摘要

本文介绍了2017- 2019年在安卡拉进行的实地研究，以确定红花(Carthamus tinctorius L. var. Remzibey-05)对草甘膦漂移率的响应。采用CO2加压背负式喷雾器，以18.9、4.5和1.44 g有效成分(a.i) ha-1的剂量，以19.2 L ha-1的喷雾量施用于2-4个真叶期的红花幼苗。在处理后28天(DAT)和收获时测定除草剂对作物的伤害和减产。随着草甘膦漂移剂量的增加，红花植株发生的植物毒性也随之增加，达到68.75-73.75% 28 DAT。与未处理的对照相比，草甘膦最低漂移率造成的产量下降有限，为13-25%。在最高漂流剂量下，植株不能产生穗和种子。

Safflower (Carthamus Tinctorius L.) Response to Drift Rates of Glyphosate

The paper presented the field studies carried out in Ankara during 2017- 2019 to established the safflower responses (Carthamus tinctorius L. var. Remzibey-05) to drift rates of glyphosate. The herbicide at the rate of 18, 9, 4.5 and 1.44 g active ingredient (a.i.) ha-1 was applied at a spray volume of 19.2 L ha-1 to safflower seedlings at 2-4 true leaf stage using a CO2 pressurized knapsack sprayer. Crop injury and yield reduction caused by the herbicide was determined at 28 days after treatment (DAT) and at harvest. As the drift dose of glyphosate increases, the phytotoxicity occurring in the safflower plant also increases and reached to 68.75-73.75% 28 DAT. Yield reduction caused by the lowest drift rate of glyphosate was limited, 13-25%, compared to the nontreated control. At the highest drift dose, the plants could not produce spike and seeds.

期刊介绍： The Journal ROMANIAN AGRICULTURAL RESEARCH is an “open access” one, which publishes original articles, short communications, presenting new scientific results – theoretical, experimental and technical – on plant breeding and genetics, physiology, biotechnology, mineral nutrition and plant protection, in field crops. Reviews on up-to date subjects and recent research, preferably from Eastern Europe, may also be published.
