非豆科作物生产力部分依赖于硝酸盐的吸收与还原.为了研究植物的硝酸盐同化途径,将除草剂氯酸盐用作硝酸盐的同功模拟.15个软红粒冬小麦幼苗表现出对120μM氯酸盐可见叶片失绿症的显著变异已由其他学者报道.从其研究中,我们选择了3个耐氯酸盐和3个敏感品种并测定了(15)~硝酸直注入量与同化作用,以确定这些特性是否与氯酸盐敏感性差异有关.120μM氯酸盐对植株生长、叶片叶绿素含量以及营养成份的影响也被进行了定量评价.除1个耐氯酸盐品种外,其它品种在氯酸盐存在时都减少了生长量和主茎老时叶绿素水平.不论是组织硝酸盐含量,还是(15)~N-硝酸盐注入量和同化作用都与氯酸盐敏感性无关.那些与硝酸盐同化无关的氯酸盐毒害作用以及吸收的硝酸盐和氯酸盐间的互作会改变这些品种对氯酸盐的反应.那些与硝酸盐吸收和同化有关的小麦氯酸盐敏感性推断是不恰当的.
In order to investigate nitrate assimilation pathways in plants, herbicide chlorate was used as a synergistic simulation of nitrate. Fifteen soft-red winter wheat seedlings showed no effect on 120 μM Chlorate-visible leaf chlorosis significant variability has been reported by other scholars.From its study, we chose three perchlorate and three sensitive varieties and measured (15) ~ nitric acid injection and assimilation To determine whether these characteristics are related to the chlorate sensitivity differences.120 μM chlorate on plant growth, leaf chlorophyll content and nutritional content has also been quantitatively evaluated.In addition to a perchlorate variety, other varieties In the presence of chlorate, both the amount of growth and the chlorophyll level in the main stem were reduced both in terms of tissue nitrate content, (15) -N-nitrate influx and assimilation were not associated with chlorate sensitivity Chlorate poisoning, which is not associated with nitrate assimilation, and the interaction between absorbed nitrate and chlorate alter the response of these species to chlorate, and those associated with nitrate uptake and assimilation Off it is not appropriate.
