摘　要：

研究了不同温度和不同土壤湿度条件下, 三种甲氧基丙烯酸酯类杀菌剂吡唑醚菌酯、醚菌酯、嘧菌酯以1 g a.i.•kg^-1 (种子)的处理剂量对花生幼苗生长及生理作用的影响。结果表明: 湿度一定时, 随温度的升高, 花生幼苗的株高、主根长、地上鲜重和地下鲜重等生物学性状和保护酶(SOD、POD、CAT)等生理生化指标提高, 25 ℃下花生生长状态最佳; 60%湿度下, 花生幼苗的株高等生物学性状和保护酶、转氨酶等生理生化指标, 均好于40%和80%湿度条件下。三种药剂拌种处理后可以促进花生幼苗的生长, 提高叶片保护酶(SOD、POD、CAT)和转氨酶(GPT、GOT)活性, 增加叶绿素和叶片可溶性蛋白含量, 提高根系活力。

Abstract:

The effects of seed dressing with strobilurin fungicides (pyraclostrobin, kresoxim methyl and azoxystrobin) on the physiological and biochemical characteristics in peanut (Arachis hypogaea Linn.) seedling were investigated at different temperatures and in different humidity. The dosage was 1 g a.i.•kg^-1 (seeds). It was indicated that the plant height, main root length, above-ground fresh weight, underground fresh weight and the other agronomic characteristics of peanut plant as well as the protective enzymes (SOD, POD and CAT) and other physiological indexes increased with the increasing temperature, and the best index was obtained at 25 ℃. The agronomic characteristics such as plant height and physiological indexes such as protective enzymes, transaminase of peanut seedlings achieved the best result in the humidity of 60%. The three fungicides can promote the growth of peanut seedlings, improve protective enzymes (SOD, POD, CAT) and transaminase (GPT, GOT) activity, increase chlorophyll, soluble protein content and root activity.
