查询词典 drought

Vent were studied in this experiment based on scanner-based image analysis. The results showed that drought and AM inoculation had a large, significant effect on plant development. Biomass, total length, surface area, volume, number of root nodes, average diameter and fractal dimension of root system in Broussonetia papyrifera Vent decreased with the reduction of soil moisture, while they were increased by AM inoculation. Special root length in non-AM plants increased when soil moisture was reducing, but it was decreased by AM inoculation.

结果表明，土壤水分状况和接种菌根真菌对构树幼苗生物量积累产生了显著的影响；构树幼苗根系干重、总长度、表面积、体积、根节数目、根系平均直径和分形维数表现出随着土壤含水量的降低而降低，接种G.mosseae则使得该参数比同等水分条件下显著升高；未接种植株比根长SRL表现为随着土壤含水量的降低而升高，接种G.mosseae则降低了同等水分条件下构树幼苗的比根长；土壤水分和接种G.mosseae同样也对根节平均长度产生了影响。

The stress resistance of common roof garden plants, e.g. Dahlia hybrida, Callistephus chinensis, Calendula officinalis and Chrysanthemum multicaule were determined by mensurating such index as chlorophyll content, electrolyte leakage, water content, Pro content, MDA content and dissoluble sugar content. The result indicates that Dahlia hybrida is the best, Callistephus chinensis next, Calendula officinalis and Chrysanthemum multicaule are weaker as to drought resistance;while in the experiment on coldness resistance, the ability to bear coldness ranks from the best to the worst is Poa annua, Festuca arundinacea and Trifolium.

对小丽花、矮翠菊、金盏菊与黄晶菊等常见城市绿化植物进行的抗逆性试验研究，测定了叶绿素含量、膜相对透性、相对含水量、脯氨酸含量、丙二醛含量、可溶性糖含量等指标，结果表明：在抗旱性试验中小丽花的耐受性最强，矮翠菊次之，金盏菊与黄晶菊的耐受性较弱：抗寒性试验中所选植物材料的耐受性次序分别是早熟禾强于高羊茅强于三叶草。

The seed of Camelina sativa contain 5.67% jelly which envelopes the seed and could absorb 181.31 times water. This might be the main cause that the seeds of Camelina sativa absorb more water in more rapid speed than wheat, which can explain the drought-resistance of Camelina sativa.

亚麻荠种子的外层胶质占种子总重的5.67%，可吸收181.31倍的水分，使种子在最初10min内即可吸收相当于自身重量8倍的水分，浸泡24h后吸水量达到10倍左右；而小麦种子浸泡24h后吸水量只有54.7%，据此认为这可能是亚麻荠种子抗旱性较强的原因。
