影响苜蓿锈病夏孢子萌发因素的研究

Study on Factors of Influencing Germination of Uromyces striatus Urediniospores.

研究结果表明，粉锈宁、多效唑、翠竹牌植物生长剂对夏孢子的萌发均有显著的抑制作用，农用稀土和细胞分裂素对夏孢子的萌发没有抑制作用；苜蓿锈菌夏孢子在冬季时间较长的北方。

ffects of five medicaments were tested on the germination of Uromyces striatus urediniospores. The result showed that triadimefon. Paclobutrazol and plant-growth substance “green bamboos Pai' have obvious effects on urediniospores, but the farm rare-earth and cytokinin have not. Furthermore, it was ascertained that the urediniospores have lost their germinabilities after six months in north China where the winter time is long.
