重遮阴下小种子品种净光合速率显著高于大种子品种，小种子西瓜品种幼苗期对弱光环境的适应性更强。 - The growth traits , as - tolerance and bioaccumulation of different pteris vittata genotypes , which were collected from different areas of china , were studied . the result showed that there was a remarkable difference in plant height , number of frond and sprout , fresh weight of above - ground parts and roots among different genotypes . plant height varied from 29 . 6 to 68 . 2 cm , frond from 13 . 3 to 60 . 0 per plant and sprout from 9 . 0 to 65 . 7 per plant , fresh weight of aboveground parts and soil ranged from 150 to 540 g and from 20 . 3 to 94 . 9 g per plant , respectively
研究了分布于我国不同地区的蜈蚣草基因型的生长特性、砷耐性和富集特性，结果显示：蜈蚣草基因型间株高、羽叶数、芽苞数、地上部鲜重、根部鲜重均有显著的差异，株高变化在29 . 6 - 68 . 2cm ，羽叶数变化在13 . 3 - 60 . 0个株，芽苞数变化在9 . 0 - 65 . 7个株，地上部和地下部鲜重分别变化在150 ? 540克株和20 . 3 - 94 . 9克株。 - To assess the medicinal value of cultural anisodus tanguticus , the contents of four bioactive tropane alkaloids , anisodine , anisodamine , scopolamine and atropine , in cultural and wild materials were determined by the hplc method . the results showed that content of each alkaloid in the aboveground parts of cultural and wild samples was lower than that in roots , and this explained why it was not the whole plant but the root that was used as medicinal materials . the content of each alkaloid in the roots of one - year cultural material was lower than that in the two - year plants . the discrepancy of the total of four alkaloids between one - year and wild plants is not significant . moreover , the total of four alkaloids , and the contents of anisodine , scopolamine , and atropine in two - year plants were higher than those in wild plant . thus there is medicinal value in the cultivated a . tanguticus as well as wild a . tanguticus , especially in the two - year cultural a . tanguticus
为了评估人工栽培山莨菪的药用价值,采用高效液相色谱技术对人工栽培和野生山莨菪的地上部分和根中具有生物活性的4种托烷类生物碱:樟柳碱、山莨菪碱、东莨菪碱和阿托品的含量进行了测定.结果表明无论是人工栽培还是野生植物,地上部分中4种生物碱含量均远低于根,这解释了人们为什么用山莨菪的根而不是整株入药.在栽培植物的根中,一年生山莨菪中各生物碱含量均小于二年生山莨菪,其根中4种生物碱总量与野生根相比差异不是很明显;二年生山莨菪根中, 4种生物碱总量以及樟柳碱、东莨菪碱和阿托品含量均比野生的高.这说明人工栽培的山莨菪,尤其是二年生山莨菪,同野生山莨菪一样具有一定的药用价值 - In contrast , plants from three populations of e . splendens showed high cu tolerance and substantial cu accumulation , under 100 umol l - 1 the plant of tl / zj / jd can accumulate 143 . 5 , 71 . 9 and 58 . 1 mg kg - 1 cu in the aboveground parts , respectively . the cu concentration in shoots was 16 to 27 times more than cu concentration in roots
在盆栽试验条件下，海州香薷和紫花香薷对土壤铜、锌、铅复合污染都具有很强的耐性，地上部分铜、锌、铅等重金属含量在植物生长期呈现动态变化，但植物地上部重金属积累量保持增加趋势。
