The Relationship Between Primary Root Hair Development And Net K+ Flux In Drought Resist And Drought Sensitive Wheat

The relationship between primary root hair development and net K+ flux in drought resist and drought sensitive wheat after being drought is researched in this paper. The Changwu 134(drought resist) and Zhongguochun (drought-sensitive) were treated by 10% PEG 6000.The net K+ ion flux was tested by Scanning ion-selective microelectrode scanning technology(SIET) before and after being treated by PEG 6000.Our results indicate that:(1)The development of primary root hairs of wheat were infected by net K+ ion flux.(2)The number of primary root hairs of drought-resist wheat was more than that of drought-sensitive wheat for strong ability of K+ absorption.
