To simulate soil drought culture solutions with different osmotic potential (from-0.7 to-10.0 bars) were employed for sorghum growth and changes of fresh and dry weight, water potential, relative permeability, content of free proline and total free amino-nitrogen in sorghum seedling were determined in the present study carried out in phytotron. The study showed that the characteristics order of sensitivity of mentioned above to drought was as following: water potential, content of free proline and total free...

To simulate soil drought culture solutions with different osmotic potential (from-0.7 to-10.0 bars) were employed for sorghum growth and changes of fresh and dry weight, water potential, relative permeability, content of free proline and total free amino-nitrogen in sorghum seedling were determined in the present study carried out in phytotron. The study showed that the characteristics order of sensitivity of mentioned above to drought was as following: water potential, content of free proline and total free amino-nitrogen>relative permeability and fresh weight>dry weight, indicating that first of all drought induced changes of water status and some of metabolic processes in plants, finally decrease of accumulation of dry material. "No.5 Jin Za" sorghum seedlings have certain ability of regulation and adaptation to drought expressed by that inhibition caused by gradual drought was less than that caused by shock drought, additionally along with prolongation of drought the changes of growth, physiology and metabolism showed a trend of detente and recover. The relationship between log content of free proline, log relative permibility, (?) based on fresh weight, and water potential of shoots was analysed and discussed.

本实验在人工气候室的人工光照室内进行。利用不同低渗透势的培养液模拟土壤干旱条件,观察较抗旱的高粱品种“晋杂5号”在此条件下的生长、生理和代谢的变化。实验表明植株水势、脯氨酸量、总游离氨态氮量在外界渗透势为-2.5巴时就会发生显著变化;鲜重和相对透性在-5.0巴时开始发生显著变化;而干重则在-10.0巴时才发生明显变化。对于干旱的变化敏感性顺序为水势、脯氨酸量,总游离氨态氮量>相对透性、鲜重>干重。表明干旱首先引起植物水分状况和某些代谢过程的变化,最后才是干物质的积累。“晋杂5号”幼苗在干旱条件下具有一定的调节适应能力,表现在渐进干旱处理时受到的抑制小于同样程度的突然干旱处理。另外,在一定的干旱范围内随时间延长,生长、生理代谢变化,有趋于缓和或恢复的趋势。本文分析并讨论了脯氨酸含量的对数(log PRO),相对透性的对数(log RP),鲜重和干重的日相对生长率((?))和植株水势(ψ)之间的关系。
