盆栽樱桃

樱桃是蔷薇科,李属,樱桃亚属果树,我国栽培的有4种,即中国樱桃、甜樱桃、酸樱桃及毛樱桃,分布很广,北起辽宁、华北,南至云、贵、川,西至甘肃、新疆等地。园艺品种很多,常见的有垂丝樱桃、泰山樱桃、短杷大果等。20世纪以来引入欧洲大樱桃,经过选育,品种日益丰富,常见的有红灯、先锋、黑珍珠、龙冠等。由于樱桃开花早,果实成熟早,加之果实含铁量比苹果、柑桔、梨高20多倍,每100克樱桃中含铁量多达59毫克,居于水果首位。

今夏樱桃售价整体下降

含铁量是苹果和梨的20倍的“贵族水果”———樱桃,今夏以“平易近人”的价格走进京城百姓家。近期,从北京四道口方正园果品批发中心了解到,目前樱桃上市量比去年扩大了30%以上,价格明显低于去年,因此销量大增。目前市场上的樱桃以山东樱桃为主,分为反季和应季两种。个头较小的应季樱桃价格在6元/kg左右,一些果肉少、味道偏酸的樱桃最低能达到5元/kg。个头偏大的应季樱桃批发价格在14～16元/kg之间。从市场上了解到,目前应季樱桃品种非常多,有“红灯”、“大紫”、“大红”、“先锋”、“意大利早红”等,还有一种名为“雷尼”的黄色樱桃。从…

Controlled vocabularies for plant anatomical parts optimized for use in data analysis tools and for cross-species studies

Background

It is generally accepted that controlled vocabularies are necessary to systematically integrate data from various sources. During the last decade, several plant ontologies have been developed, some of which are community specific or were developed for a particular purpose. In most cases, the practical application of these ontologies has been limited to systematically storing experimental data. Due to technical constraints, complex data structures and term redundancies, it has been difficult to apply them directly into analysis tools.

Results

Here, we describe a simplified and cross-species compatible set of controlled vocabularies for plant anatomy, focussing mainly on monocotypledonous and dicotyledonous crop and model plants. Their content was designed primarily for their direct use in graphical visualization tools. Specifically, we created annotation vocabularies that can be understood by non-specialists, are minimally redundant, simply structured, have low tree depth, and we tested them practically in the frame of Genevestigator.

Conclusions

The application of the proposed ontologies enabled the aggregation of data from hundreds of experiments to visualize gene expression across tissue types. It also facilitated the comparison of expression across species. The described controlled vocabularies are maintained by a dedicated curation team and are available upon request.

     

文冠果种子休眠解除方法研究

以文冠果种子为试材,设置10种不同催芽方法,包括水浴加热、不同浓度的H2_SO_4、KNO_3、PEG-6000等试剂处理文冠果种子,诱导发芽后调查种子的发芽率、活力、发芽势等发芽参数,并对不同催芽方法进行了比较分析,筛选适合文冠果种子快速解除休眠的方法。结果表明:80℃水浴加热、4%KNO_3溶液、5%PEG-6000溶液、GA_3溶液、2%KNO_3溶液、10%PEG-6000溶液、4℃蒸馏水浸种、50%H_2SO_4溶液处理,均可不同程度的提高文冠果种子的发芽率,而高浓度H_2SO_4溶液处理对文冠果种子发芽有抑制作用;文冠果种子经80℃水浴加热10min处理可使发芽率提高到55.83%,为未处理的9.3倍。     

Tables for calculating desired light flux densities for horticultural crops

Light emissions in lux from single incandescent lamps ranging from 60 to 200 watts were arranged in tables according to the lamp height above the ground. The method of calculating the desired lamp spacing to achieve a desired light intensity is illustrated. A table showing the reduced light emission due to various voltage drops is given along with precautions to avoid them.

Bromeliad growers report severe leaf quality problems for Aechmea cultivars grown under commercial greenhouse conditions. In this research, a leaf damage ‘sensitive’ and ‘insensitive’ A. cultivar were compared for their C-metabolism and hydrophysiology under these greenhouse conditions. Stomata opening index indicated CAM (Crassulacean acid metabolism) for both cultivars, with 45–50% open stomata around 4:00 a.m. and 5–10% in the afternoon. Malic and citric acid were the major organic acids present in the leaves, with diurnal malic acid accumulation during the night. The leaf damage ‘sensitive’ cultivar showed higher malic acid accumulation than the ‘insensitive’ cultivar (200 μmol/gfw versus 170 μmol/gfw). Leaf osmotic potential and turgor pressure were linked with diurnal malic acid fluctuations: organic acid accumulation during the night generated high leaf turgor pressures (up to +0.86 MPa).A leaf damage sensitivity test was designed and confirmed previous experiences of several bromeliad growers. Both cultivars showed higher leaf damage percentages (98 and 78%) when leaf malic acid accumulation was high. We attribute this elevated sensitivity to lethal turgor pressures and consider them to be caused by the water capturing mechanism generated by high organic acid accumulation. Under current greenhouse conditions, this water capturing mechanism can be disastrous for plant leaf quality. Especially, under high relative humidity, hindering plant transpiration and stimulating water uptake by dew formation, leaf quality could be endangered.
