本文研究了三唑酮(粉锈宁,triadimefon,Bayleton)的某些植物生长调节作用。0.0005～0.05％(1.7×10~(-5)～1.7×10~(-3)克分子浓度)的三唑酮强烈抑制小麦芽鞘切段的生长;在0.001～0.1％范围内抑制小麦幼苗的株高和地上部分的干、鲜重,促进根长和根的干、鲜重,提高了幼苗的根冠比;在0.001～0.1％范围内显著增加小麦幼苗单位叶面积的叶绿素含量和光合放氧量。 In this paper, some plant growth regulatory effects of triadimefon (Triadimefon, Bayleton) were studied. Triadimefon at a concentration of 0.0005-0.05% (1.7 × 10 -5 -1.7 × 10 -3) strongly inhibited the growth of the cuticle of wheat germplasm. In the range of 0.001-0.1%, the inhibition of wheat seedlings Of the plant height and shoot dry weight, fresh weight and root length and root weight, increased root and shoot ratio of seedlings; significantly increased the leaf chlorophyll content and photosynthesis of wheat seedling units in the range of 0.001 ~ 0.1% Oxygen consumption.
