通风对好好吧无性系芽的增殖能力和抗旱能力的影响作用

该文旨在研究通风在不同好好吧无性系芽增殖阶段对它们增殖体的叶面积、地上部分总面积和失水能力的作用,筛选抗旱性好的好好吧无性系。研究结果表明,在13个好好吧无性系中,通风使他们的叶面积、总面积和抗失水力均有增加。其叶面积分别增加了72.2％到470.5％,其总面积分别增加了39.0％到145.8％,其抗失水力分别增加了(失水分别减少了)22.2％到138.0％。从中选择了一个叶面积和总面积都增加最多(分别为470.5％与145.8％)和失球减少次多(86.7%)的耐旱好好吧无性系CQ63,可供沙漠和旱地种植。

Effect of ventilation on the proliferation and drought-resistance of jojoba (Simmondsia chinensis ) clones

The purpose of this research is to study effect of ventilation on leaf area,shoot area and water loss in different jojoba clones,and select some drought-resistant jojoba clones from those at their proliferation stage. The research results showed that ventilation helped increase their leaf areas from the percentage of 72. 2% to 470. 5%,total area of jojoba propagules from 39% to 145. 8% and their resistance to(decrease in)water loss from 22. 2% to 138. 0% in 13 jojoba clones. One good drought-resistant jojoba clone,CQ63, was selected with the most increase of 470. 5% in leaf area and 145. 8% in total area as well as a greater decrease of 86, 7%(the second-most one among 13 clones)in water loss to be planted in arid desert and land.
