Topography strongly affects the distribution of insolation in the terrain. Patterns of incoming solar radiation affect energy and water balances within a landscape, resulting in changes in vegetation attributes. Unlike other regions, in seasonally dry tropical forest areas the potential contribution of topography-related environmental heterogeneity to β-diversity is unclear. In Mt. Cerro Verde (Oaxaca), S. Mexico, we: (1) modelled potential energy income for N- and S-facing slopes based on a digital elevation model, (2) examined the response of vegetation structure to slope aspect and altitude and (3) related variations in plant diversity to topography-related heterogeneity. Vegetation survey and modelling of potential energy income (SOLEI-32 model) were based on 30 plots equally distributed among three altitudinal belts defined for each slope of the mountain; combining the three altitudinal belts and the two slopes produced six environmental groups, represented by five vegetation plots each. Potential energy income was about 20% larger on the S than on the N slope (9,735 versus 8,138 MJ/m2), but it did not vary with altitude. In addition, the temporal behaviour of potential energy income throughout the year differed greatly between slopes. Vegetation structure did not show significant changes linked to the environmental gradients analysed, but altitude and aspect did affect β-diversity. We argue that the classic model of slope aspect effect on vegetation needs reconsideration for tropical landscapes.

Yield management is important subject in modern grape growing and winter pruning and cluster thinning treatments were used for yield control. Standard cluster thinning is generally labor intensive and expensive method and grape growers try to new methods, which are alternative to cluster thinning for reducing berry set. The goal of the present research was to investigate the effects of chemical thinning treatments such as ethephon (ETH), gibberellic acid (GA3), naphthalene acetic acid (NAA) and non-chemical thinning treatments such as early leaf removal (ELR) and standard cluster thinning (SCT) on decreasing grape yield and enhancing berry composition of cv. Shiraz. In this study, percentages of berry set of cv. Shiraz were decreased by both chemical and non-chemical thinning treatments compared to Control. The results from these two different thinning methods shown certainly significant differences in berry composition of cv. Shiraz. Eventually, the best results in improved quality characteristics of cv. Shiraz were obtained from ELR treatment and treatments of ELR, ETH, GA3, NAA and SCT successively resulted in considerable enhancements in quality attributes of cv. Shiraz.  相似文献

Utilization from bio fertilization is well known a considerable tool to improve the yield and fruit quality of various crop fruits through the increasing emphasis on maintain of soil health, minimize environmental pollution and decrease the use of chemical fertilization. In this study, in order to improve wine grape quality features of cv. Shiraz, four different doses of foliar microbial fertilizer, including 0, 1000, 2000 and 3000?ppm were applied at two different terms as Term I (mostly; pre-bloom applications) and Term II (mostly; post-bloom applications). However, there were no influences of application terms of foliar microbial fertilizer treatments; treatment doses had considerable effects on yield and quality parameters. The lowest p-values, meaning the highest berry quality, from doses of foliar microbial fertilizer were obtained from 2000?ppm (105.08?μW), 1000?ppm (110.40?μW), 3000?ppm (112.97?μW) and 0?ppm (119.58?μW). Comparing the applications of foliar microbial fertilizer, it was observed that doses of 2000?ppm (3155.56?mg/kg), 1000?ppm (3000.92?mg/kg) and 3000?ppm (2530.19?mg/kg) exhibited higher total phenolic compounds content when compared with 0?ppm treatment (2206.97?mg/kg). Berries from grapevines applied with the doses of 2000, 1000 and 3000?ppm foliar microbial fertilizer respectively shown higher total anthocyanin content such as 1230.19, 1160.85 and 865.86?mg/kg compared to 0?ppm (637.37?mg/kg). As a result, research the findings indicated that 2000 and 1000?ppm doses of foliar microbial fertilizer were obviously effective on wine grape quality features of cv. Shiraz in terms of electrochemical property, total phenolic compounds content and total anthocyanin content.  相似文献

In this study, average weight, colour, soluble solids content and titratable acidity were determined as quality parameters of strawberry fruits while ascorbic acid, total anthocyanins, total phenolics, total flavonoids, minerals and trace elements content as nutritional parameters. All these attributes along with the DPPH radical scavenging activity were screened in two strawberry genotypes grown on the same site at the ripe stage. Also, the phenolic profiles of the strawberry fruits were obtained by HPLC. Except colour, results showed no significant differences between cultivars in quality parameters. Ascorbic acid found for ‘Premial’ cv. (81.62?mg/100?g) was twice the amount found in ‘Magic’ cv. (42.15?mg/100?g), total phenolics varied from 207.95 (cv. ‘Premial’) to 249.98 (cv. ‘Magic’) mg GAE/100?g while total flavonoid content in fruits of ‘Magic’ cultivar (79.56?mg/100?g) was 2?fold higher than the one of the ‘Premial’ cv. The quercetin content ranged from 2.72 to 4.66?mg/100?g, whereas free ellagic acid ranged from 6.79 to 9.03?mg/100?g. The pale shiny fruits of ‘Premial’ cv. (higher L*, ho and chroma index) had a lower total anthocyanin content (19.07?mg CG/100?g) than the bluish fruits of the ‘Magic’ cv. (23.96?mg CG/100?g). An inverse relationship between the levels of ascorbic acid and anthocyanin contents was also noticed in strawberry samples. Significant differences were found also in minerals and trace elements content of the two strawberry cultivars. The results revealed the importance of genetic background for the content of antioxidant compounds in strawberry fruits.  相似文献

This study has been conducted with the aim to determine the type of nutrient medium that can be used in micropropagation studies for ‘Öküzgözü’ and ‘Bo?azkere’ and to specify BAP concentrations. In the study where ejectors with a length of 0.7–0.8?cm that are obtained with single-node culture are used, it was focused on four different nutrient media such as MS, DKW, QL and WPM and on six different concentrations such as 0.2–0.4–0.6–0.8–1.0–1.5 mg l?1 BAP. Single-node suspension explants which will be used in initiating the culture, are taken into culture in MS nutrient medium and the nutrient medium is supported with 30?g l?1 sucrose, 6?g l?1 agar and 1?mg l?1 BAP. In the trial environment, parameters such as number of shoots, shoot length (cm), number of nodes and callus ratio have been investigated. For both grape varieties, the best outcome was obtained with MS nutrient medium with respect to number of shoots, shoot length, and number of nodes. These values were found as 4.66, 1.24 and 6.39 for ‘Öküzgözü’ variety respectively, whereas they are determined as 6.28, 1.15 and 6.81 for ‘Bo?azkere’ variety respectively. In both grape varieties in DKW nutrient medium, starting from the 2nd week of culture, obscuration began to appear on the shoots and after this stage no other development has taken place.  相似文献

The aim of the present research was to investigate the fruit quality of twenty different local pear varieties (Pyrus communis L.), namely Ahlat, Ankara, Arpa, B?ld?rc?n, Çermai, Cinci, Gelin Bo?an, Hac? Hamza, Hah?r, Kabak, K?z?l, Kokulu, Mehrani, Menendi, Sulu, ?algam, Tokat Sultan?, Tur?u, Yaz, and Yaz Meyri?i, grown in Gumushane province in terms of pomological and morphological characteristics and chemical compositions. The fruit mass, fruit width and length, fruit stem thickness and length, fruit kernel width and length, hardness of pulp, number of seeds, leaf width and length, leaf stem length and thickness, and water soluble dry matter (WSDM) of the pear fruits have been determined as pomological and morphological characteristics. On the other hand, the chemical compositions of the pear varieties have been evaluated in terms of protein, ash, sucrose, fructose, glucose, total sugar, titratable acidity, moisture, and mineral element levels.Both pomological and morphological results demonstrated that the local pear varieties are important in terms of rehabilitation studies and detailed selection studies on these local varieties should be performed. The chemical analyses result of the pear varieties revealed that there is no component that may be harmful to human health when consumed, and also these varieties contains the necessary amount of mineral elements.  相似文献

Protection of biodiversity and ecosystem functions requires a better understanding of spatial diversity. Here we studied diversity patterns of true bugs and saproxylic beetles, sampled in 28 forest stands of southern Germany, using a hierarchical nested design of five increasingly broader spatial levels: trap location, stratum, forest stand, forest site, and ecoregion. We predicted that: (1) for large body-sized species (as a surrogate for highly mobile species) and host generalist species (low host specificity), the proportion of β-diversity decreases from small to large spatial scales; and (2) the differences between trait-based functional guilds in the proportion of β-diversity increase with increasing weighting of more-abundant species. Our results indicated that the ecoregion level is the most important diversity scale for both taxa and among functional guilds sampled, followed by the forest stand level. Specialized species were more strongly affected on the ecoregion level than generalist species. Differences in the proportion of β-diversity between functional guilds increased with increasing weighting of abundant species. The β-diversity patterns based on body size and host specificity were similar for true bugs, but partly contrasting for saproxylic beetles. Our results suggest that (1) future conservation schemes should focus on establishing new conservation sites in new ecoregions, rather than on enlarging existing protected areas; (2) host specificity might be a more meaningful trait than body size to be considered in biodiversity studies; and (3) common conservation approaches restricted to only large, conspicuous, but rare species might result in a mismatch of important biodiversity scales.  相似文献

Uneven grape ripening, leading to decreases economic valued of grapes is one of the main problems faced by grape growers in early table grape growing. In recent years, there has been increasing concern about improving of fruit quality in fruit crops. Among the various quality improvement methods, different types of foliar compounds are used for this purpose and hydrogen peroxide (H2O2) and phenylalanine (Phe) can be given as examples to some of these chemicals. This research was carried out during the 2015 growing season by using early ripening table grape cv. Trakya Ilkeren. In the study, it was assessed that how different doses of hydrogen peroxide (0, 10, 20 and 40?mM) and phenylalanine (0, 1, 2 and 4?mM) affected physical and biochemical properties of cv. Trakya Ilkeren. In terms of physical properties, doses of hydrogen peroxide and phenylalanine had only significant effects on grape firmness and cluster length. The best results were obtained from 4?mM Phe application (6.76?N) in grape firmness and were obtained from applications of 10, 20 and 40?mM H2O2 (23.66, 23.86 and 23.99?cm) and applications of 1, 2, and 4?mM Phe (23.95, 24.46 and 24.88?cm) in cluster length. However, most of biochemical properties were considerably affected by doses of hydrogen peroxide and phenylalanine except for juice pH and p-value. It was recorded that the highest total phenolic compounds contents varied from 3571.28 (10?mM H2O2) to 3871.22?mg GAE kg?1 fw (40?mM H2O2) compared to 0?mM application (2591.48?mg GAE kg?1 fw). In terms of total anthocyanin content, the highest mean was recorded for 4?mM Phe application (330.56?mg GAE kg?1 fw) than 0?mM application (168.79?mg GAE kg?1 fw). As a result, 4?mM Phe application particularly improved the most of biochemical properties in cv. Trakya Ilkeren.  相似文献

The goal of this study is to do the energy input-output analysis of organic mulberry. This study was conducted at the organic mulberry producing facilities during the 2015–2016 production seasons in Adiyaman-Tut region of Turkey. The agricultural input energies and output energies used in organic mulberry production were computed to determine the energy input-output analysis. According to the research findings, the energy inputs in organic mulberry production were computed respectively as 3948?MJ ha?1 (59.01%) drip and sprinkler irrigation energy, 1092.42?MJ ha?1 (16.33%) gravity irrigation energy, 449.33?MJ ha?1 (6.72%) diesel fuel energy, 416.52?MJ ha?1 (6.23%) farmyard manure energy, 335.14?MJ ha?1 (5.01%) human labour energy, 253.52?MJ ha?1 (3.79%) machinery energy, 93.12?MJ ha?1 (1.39%) transportation energy, 75.78 MJ ha?1 (1.13%) animal labour energy and 26.62?MJ ha?1 (0.40%) organic fertilizer energy. Total input energy was computed as 6690.46?MJ ha?1. Production output organic mulberry yield were calculated as 37,627.84?MJ ha?1. The energy output/input ratio, specific energy, energy productivity and net energy computations were computed respectively as 5.62, 1.51?MJ kg?1, 0.66?kg MJ?1 and 30,937.37?MJ ha?1. The consumed total energy input in organic mulberry production could be classified as 88.20% direct, 11.80% indirect, 88.10% renewable and 11.90% non-renewable.  相似文献

In order to study the effect of nitrogen spray at different times on color and yield parameters of grape cv. Pykany, an experiment was carried out in factorial based on randomized complete block design with four replications in Khalil Abad County in 2015. The treatments included three concentrations of nitrogen (0, 5 and 10?ppm) and three spray times (Late April, before bloom stage, and after pollination and fruit set stage). Color parameters such as brightness rate (L), redness (a) and yellowness (b), chroma, hue angle and browning index were evaluated in this experiment. The results of variance analysis and means comparison showed that the effect of treatment containing spray at concentration of 10?ppm on yield was significant at 1%. There were not significant differences among treatments of urea concentrations and spray times on L and b but different concentrations of urea had significant effect on a* at the level of 1%, so that the highest amount of significant difference was due to the treatment of urea spray at the concentration of 10?ppm and the lowest amount was due to the control treatment. Furthermore, the interaction effect of concentration and different times of nitrogen application on color intensity index was significant at the level of 5%. Based on the results, the effect of different concentrations of urea spray on hue angle was significant at 1% so that the highest level of significant difference was due to the concentration of 10?ppm and the lowest was related to control treatment.  相似文献

Sunlight influences many morphological, biochemical and molecular changes in fruits and the most important is color change associated with the development of pigments. The exposure to sunlight influences the anthocyanin content of the fruit peel. With the aim to understand the influence of bagging of fruits on the mango peel color, anthocyanin and expression of anthocyanin biosynthetic genes, an experiment was conducted by covering fruits of red colored cv. ‘Lily’ with muslin cloth. The observations were recorded for fruits of control (non-bagged) and fruits developing in shade. In bagged fruits, the color of peel changed towards lightness and yellowness. The reduction in anthocyanin was observed up to 17 times in bagged and shaded fruits. We also observed the down-regulation of all anthocyanin biosynthetic genes in fruits under bagged and shaded conditions. This study reports the influence of bagging and shade on anthocyanin biosynthetic genes and subsequent change in the color of fruit peel.  相似文献

This research was conducted to determine the changes in the seasonal carbohydrates of annual shoots and growth characteristics of 10 years old ‘Trakya ?lkeren’ grape variety. Grapevines are grafted on 5BB and 5C rootstocks and they were grown in heavy clay soil conditions. In the study, changes of sugar, starch and total carbohydrates were determined from bud burst to dormancy. While sugar, starch and total carbohydrates showed significant differences (P < 0.01) there were no differences between rootstocks. Although sugar, starch and total carbohydrates of shoots decreased from bud burst to blooming, they increased thereafter until vegetative growth stopped. Total carbohydrates of annual shoots have been found to accumulate in period from blooming to harvest. Total and mean leaf area, shoot length and diameter, total chlorophyll and chlorophyll a/b ratio showed significantly variation among rootstocks and phenological stages (P < 0.01). Whereas the highest chlorophyll contents were found in the blooming, it was found at the lowest through to harvest. Overall mean and total leaf area, shoot length and shoot diameter, total chlorophyll content and chlorophyll a/b ratio were significantly higher on 5BB grafted vines. In the study, 5BB rootstocks are found suitable in terms of shoot carbohydrate accumulation and growth characteristics for ‘Trakya ?lkeren’ grape variety.  相似文献
