摘要

以毛乌素沙地优势植物柠条(Caraganaintermedia)和沙蒿(Artemisiasongaricaschrenk)种子为对象

采用人工模拟干旱试验方法

研究不同电场处理后这2种植物种子萌发和生物量对土壤干旱胁迫的响应。结果表明

电场处理缓解了2种植物随干旱程度加重出现的负效应

不同处理条件

种子萌发和生物量对干旱胁迫的适应性的影响不同

电场处理能够提高种子在干旱胁迫条件下的发芽率和发芽势

提高2种沙生植物生物量干重和鲜重。这些变化缓解了干旱胁迫对柠条和沙蒿种子的伤害

提高了其对干旱胁迫的适应性。

Abstract

Seeds of the Caragana intermedia and Artemisia schrenk songarica in Maowusu sandland were treated with different strongths of electric current. Under controlled conditions the effects of the exposure to electric fields on the drought resistance of the seeds in the germinating stage were tested. The results show that electric field treatment can reduce the negative impacts of drought. The different electric field strengths have different effects on the drought stress adaptability of the seeds in the germinating stage and on plant biomass. It is concluded that electric field treatment can increase seed germinating potential

germination rate

plant biomass and both wet and dry weights. All these changes are favorable for reducing drought damage and improving plant adaptation.
