不同烟草种质对玉米田除草剂的耐药性鉴定

关键词：
烟草;玉米田除草剂;药害;耐药性
摘  要：
为研究生产上主栽及常用的烟草种质对玉米田常用除草剂的耐性水平,于温室中鉴定了35份烟草种质对炔草酯和莠去津的耐药性。参试的35份种质,在品种耐药性反应谱系图上可划分为高度耐药、中度耐药、中度敏感和高度敏感4类。对炔草酯高度耐药的有9份,中度耐药的有11份,中度敏感的有9份,高度敏感的有6份;对莠去津高度耐药的有14份,中度耐药的有8份,中度敏感的有5份,高度敏感的有8份。不同种质的耐药性差异分析结果显示,不同耐药类型种质的药害率、药害指数和相对耐药指数差异显著。

摘  要：
In order to identify tolerance of tobacco ge rmplasm to common corn herbicides clodinafop-propargyl and atrazine, 35 tobacco germplasms were tested in greenhouse. According to variety tolerance response ancestry, 35 tobacco germplasms can be divided into four types: the highly tolerant, the moderately tolerant, the moderately sensitive and the highly sensitive. The results showed that there were 9 varieties with the highly tolerant to clodinafop-propargyl, and 11, 9 and 6 varieties with the moderately tolerant, the moderate sensitive and the highly sensitive, respectively.s. And there were14 varieties with the highly tolerant germplasms to atrazine, and 8, 5 and 8 varieties with the moderately tolerant, the moderately sensitive and the highly sensitive, respectively. Based on analysis on tolerance of different germplasms, damage leaf ratio, damage index and relative damage index were significant different(P<0.05) among tolerance types.
