| 摘 要： | 目的]研究小麦生长过程中Cu和Cd胁迫对土壤蔗糖酶活性的影响。方法]以烟农19为供试小麦品种,采用盆栽方法,研究小麦不同生育期Cu和Cd胁迫及其复合污染对小麦根区、非根区蔗糖酶活性的影响。结果]Cu和Cd胁迫下蔗糖酶活性随小麦生育期的推移变化趋势存在一定差异,但从幼苗期到抽穗期同类金属处理下根区、非根区酶活性变化趋势相似,且蔗糖酶活性最大值出现在抽穗期或成熟期。除拔节期,Cu-Cd交互作用增大了Cd单因素作用下的根区、非根区及Cu单因素作用下的非根区的蔗糖酶活性,而对拔节期单因素作用总体表现为降低作用。总体上看,Cu、Cd单独作用下根区蔗糖酶活性大于非根区。结论]小麦根际对Cu、Cd胁迫下土壤蔗糖酶活性有一定的影响,并随小麦生长时期及重金属种类、处理浓度的不同而存在一定的差异。

| Abstract: | Objective]The purpose was to study the effects of Cu and Cd stress on soil invertase activity during wheat growth.Method] With Yannong 19 as the tested wheat variety,the effect of Cu and Cd stress and their compound pollution on soil invertase activity in both root-zone and non root-zone during wheat growth were studied in pot test.Result] The soil invertase activity had some difference along with the growth process of wheat under the stress of single Cu and Cd,but it had the similar trend in both wheat ... |
