Vermicomposts are produced through interactions between earthworms and microorganisms in the breakdown of organic wastes. Aqueous extracts were prepared in commercial brewing equipment (Growing Solutions Inc.) from vermicomposts processed from pre-consumer food waste. The ratio of vermicompost to water was 1 to 5 v:v to produce a 20% aqueous solution. The effects of soil drenches at dilutions of 20%, 10%, and 5% vermicompost extracts, were compared with those of deionized water, in the suppression of green peach aphids, mealybugs, and two spotted spider mites attacking tomatoes and cucumbers, in greenhouse cage experiments. 相似文献

Stem brown canker or Botryosphaeria canker disease impairs the growth and kills the shoots, limbs and even trunks of infected apple trees. Apple roots are usually colonized by arbuscular mycorrhizal fungi, which may have a positive influence on plant growth and suppression of diseases. In order to assess the efficacy of AM to suppress the disease severity and plant growth enhancement, nine AMF inoculation treatments (Sclerocystis dussi, Glomus intraradices, G. fasciculatum, G. bagyaraji, G. leptotichum, G. monosporum, Gigaspora margarita, a mixed AM culture and a non-mycorrhizal control treatment) were used in this present study. Two-year-old potted apple plants, maintained under glasshouse conditions, were either pre-inoculated with AMF followed by stem inoculation with Botryosphaeria ribis or simultaneously inoculated with Botryosphaeria ribis and AM. The results indicated that the incidence of canker was less severe in plants inoculated with AMF in comparison to non-mycorrhizal control. Timing of inoculation also had a significant effect on disease development and plant survival. Plants pre-inoculated with mycorrhiza performed better over those inoculated simultaneously with Botryosphaeria ribis and AM fungi. Furthermore, AM inoculation resulted in improved survival and growth of AMF-colonized plants; though, it varied by species of AM fungi utilized. 相似文献

A large number of soybean (Glycine max L.) genotypes of diverse growth habit and adaptive characters were used in the experiment. Soil salinity-induced changes
in nine morpho-physiological characters of 30-day-old seedlings of 170 soybean genotypes were compared in the study. The first
and second principal components (PC) of principal component analysis (PCA) results accounted for 97 and 2.5%, respectively,
of the total variations of soybean genotypes. The variation for the first PC was composed mainly of relative total dry weight
(DW), relative shoot dry weight, as well as petiole dry weight. There were four clusters distinguished in the cluster analysis.
The genotypes in cluster IV performed better in respect to relative total dry weight and relative shoot dry weight and hence
having salt tolerance. The genotypes clusters III performed very poorly and those of clusters II and I were moderate to poor.
D2 analysis indicated that the clusters differed significantly from each other. Discriminant function analysis (DFA) again
asserts strongly that more than 92% of the genotypes were correctly assigned to clusters. Both PCA and DFA confirmed that
the relative total DW followed by shoot and petiole DW were the major discriminatory variables, and the root DW were the secondary
important variables to distinguish genotypes into groups. In this study, multivariate analyses were used in identifying the
soybean genotypes of desirable traits for salt tolerance. 相似文献

An exploratory survey was carried out to assess economics and employment generation of the trade of bamboo and bamboo-based
secondary products in the eastern Bangladesh, to obtain reliable information about their status, socio-economic significance,
production and marketing. The study was undertaken over 30 bamboo-based enterprises in a suburban market of eastern Bangladesh,
to investigate regional product details, economic profitability and employment opportunities. The sample entrepreneurs, corresponding
to about 25% of the bamboo enterprise population were interviewed using a semi-structured questionnaire. About 202 full and
part-time workers were employed in the factories, under categories of artisan (who manufactured secondary products). The average number of worker’s in the large, medium and small factories were 9 (artisan
40%), 6.45 (artisan 35%) and 5 (artisan 25%) respectively. The study revealed that there was always a satisfied demand of
skilled artisans. Most of the workers were relatively newly employed (not more than 5 years). The daily wage rate varied between
70 and 130 Tk. ($US 1 equals approximately 70 Bangladeshi Taka (Tk.), as at December 2008). Bambusa balcooa was the most utilized species (39.96%) in terms of monetary value. The price of a single B. balcooa culm in the local market was Tk. 160–210. Nine sizes of articles under seven bamboo categories were identified, these being
bera (36″ × 120″ and 72″ × 96″), bookshelf (36″ × 24″), chaluni (12″ × 12″), chatai (48″ × 60″ and 36″ × 48″), jhuri, rickshaw hood and tukri. Net average profit per article was the highest for rickshaw hoods (Tk. 400 at the retailer stage). The total expected annual
income for an enterprises from all articles types sold was estimated to be Tk. 85,800. Three distinct marketing channels were
identified for selling bamboo and value-added secondary products. The study also generated policy implications for effective
management of bamboo-based enterprises. 相似文献

Host immune responses conducted against antigens of Eimeria bovis are key factors for the development of protective immunity against this protozoan disease. In this study we investigated
the expression of E. bovis-derived antigens on the host cell surface membrane during E. bovis first merogony in vitro. Host cells carrying E. bovis-meront I stages expressed E. bovis host cell surface antigens (EbHCSAg) on their surface membrane which were recognised by hyperimmune sera of calves and by
sera from rats immunized with E. bovis merozoites I, when tested by indirect immune fluorescent antibody test (IIFAT), laser scanning confocal microscopy (LSCM)
and immune electron microscopy. Expression of EbHCSAg on permissive host cells was earliest detected 7 days p. i., thus coinciding
with the onset of the parasite replication. Membrane-associated EbHCSAg were removed from infected host cells by proteinase
K, partially by Triton X-100, Triton X-114 and Triton X-405, but not by 1 M NaCl, CHAPS or phospholipase C treatment. Antibodies,
affinity-purified on paraformaldehyde/glutardialdehyde (PAGA)-fixed E. bovis meront I-infected bovine host cells bound to the surface meront I-carrying cells and to merozoites I (IIFAT, LSCM) but, in
contrast to untreated sera, not to sporozoites. When tested on methanol-fixed merozoites I and sporozoites by IIFAT, affinity-purified
antibodies bound to structures in the apical complex area of merozoites I, but not to sporozoites, whilst untreated sera caused
diffuse labelling of internal structures of both parasite stages. Immune electron microscopy demonstrated binding of affinity-purified
antibodies to micronemes and dense granules of merozoites I. Although the function of EbHCSAg is still unknown, results of
this study might suggest an involvement in the development of protective immunity against E. bovis infections. 相似文献

Previously, the distribution of myoepithelial cells (mecs) in the salivary glands was studied by both immunohistochemistry,
and transmission electron microscopy; however, little was elucidated concerning their morphological features, especially in
goats. This study was performed to investigate the correlation between the cytoarchitecture of the mecs in goat major salivary
glands (parotid, mandibular, and sublingual glands) and the nature of the saliva secretion. The cytoarchitectural features
of the mecs were examined by scanning and transmission electron microscopy as well as immunohistochemically. The secretory
endpieces in the parotid gland are of the pure serous type, but in both the mandibular and sublingual glands they are of the
mixed type. In all studied glands, the intercalated ducts were covered by mecs which, unlike the large stellate cells that
surrounded the secretory endpieces, were spindle-shaped with few cytoplasmic processes. Interestingly, the mecs were found
to bulge on the basal surfaces of the serous acini and intercalated ducts in all glands and to be in close contact to the
seromucous tubules surface in the mandibular and sublingual glands forming a continuous network around it. In conclusion,
the differences in the degree of development of the mecs as well as the number of their cytoplasmic processes may be correlated
with the nature of the secretion and the number of the secretory granules. Thus these observations may have some relevance
in the diagnosis of atrophy and pathogenic conditions of these glands. 相似文献

Detailed chemical studies and RAPD analysis were done in different populations of Podophyllum hexandrum collected from high altitude regions of North Western Himalayas. Random amplified polymorphic DNA (RAPD) analysis revealed a high degree of genetic diversity among the 12 collected accessions, attributed to their geographical and climatic conditions. HPLC analysis also revealed variation in the concentration of two major marker compounds which lead to the identification of a chemotype. The study demonstrated that RAPD and chemical markers are very useful tools to compare the genetic relationship and pattern of variation among such prioritized and endangered medicinal plants. 相似文献
