该文在搜集大量葡萄品种的基础上,并根据对吐鲁番地区葡萄品种资源的调查,探讨该地区现有栽培葡萄品种的"种级"隶属关系和分类问题.截至目前,吐鲁番地区的葡萄品种数量已达到555个,其中属于新疆本地的品种45个,引进品种505个(引进国内品种55个,国外品种450个),选育的品种5个.通过采集标本及对有关研究资料的分析及汇总,选出吐鲁番地区常见的具代表性葡萄品种54个,并根据其果实、种子、卷须等分类特征,首先对其进行种级分类与鉴定,而后分别进行每一种内品种的分类探讨.结果表明,上述54个葡萄品种中43个隶属于葡萄、山葡萄、圆叶葡萄、网脉葡萄4个种,11个为杂交品种或杂交种(其中3个拟定为本地杂交种). 相似文献

Atmospheric Particulate Matter (PM) constitutes a considerable fraction of urban air pollution, and urban greening is a potential method of mitigating this pollution. The value of living wall systems has received scant attention in this respect. This study examined the inter-species variation of particulate capture by leaves of seventeen plant species present in a living wall at New Street railway station, Birmingham, UK. The densities of different size fractions of particulate pollutants (PM1, PM2.5 and PM10) on 20 leaves per species were quantified using an Environmental Scanning Electron Microscope (ESEM) and ImageJ image-analysis software. The overall ability of plant leaves to remove PM from air was quantified using PM density and LAI (Leaf Area Index); any inter-species variations were identified using one-way Anova followed by Tukey’s pairwise comparison. This study demonstrates a considerable potential for living wall plants to remove particulate pollutants from the atmosphere. PM capture levels on leaves of different plant species were significantly different for all particle size fractions (P < 0.001). Smaller-leaved Buxus sempervirens L., Hebe albicans Cockayne, Thymus vulgaris L. and Hebe x youngii Metcalf showed significantly higher capture levels for all PM size fractions. PM densities on adaxial surfaces of the leaves were significantly higher compared to abaxial surfaces in the majority of the species studied (t-test, P < 0.05). According to EDX (Energy Dispersive X-ray) analysis, a wide spectrum of elements were captured by the leaves of the living wall plants, which were mainly typical railway exhaust particles and soil dust. Smaller leaves, and hairy and waxy leaf surfaces, appear to be leaf traits facilitating removal of PM from the air, and hence a collection of species which share these characters would probably optimize the benefit of living wall systems as atmospheric PM filters. 相似文献
