当落叶剂作为接触剂使用时,一般认为此药剂不能从叶子转移到植株的其他部分,尤其是在种籽里积累。我们研究了使用氯酸镁后的棉株上收获的棉籽里该药剂的吸收的可能性和积累量。选用的品种是塔什干一号和108—Φ。按常规的方法将棉花种籽种在盆钵里,出苗后使每盆留下一株棉苗,土壤含水量保持在其饱和 When deciduous agents are used as contact agents, it is generally considered that the agent can not be transferred from the leaves to other parts of the plant, especially in the seed. We investigated the potential for uptake and accumulation of this agent in cottonseed harvested on cotton plants after the use of magnesium chlorate. Selected varieties are Tashkent and 108-Φ. Cotton seeds are planted in pots in a conventional manner, leaving a cotton seedling per pot after emergence, with soil moisture remaining at its saturation
