摘要
在室外条件下,研究了单—高剂量B—9的三个不同施用时期对春蚕豆品种Maris Bead的株高、同化物的分配、产量及产量结构的影响。收获时由于不同节间的缩短,所有处理显著降低植株高度。五叶期喷施B—9暂时抑制了营养生长,提高了收获指数。十五叶期施用B—9在整个后期抑制营养生长,增加了收获指数。二十五叶期施用的B—9增加了总干物重和产量。三个处理均增加了每株豆荚数和产量,对单粒重和每荚粒数无影响。
Effects of application times of daminozide at a single, high dose rate on plant height, partitioning of assimilates, yield and yield components of spring sown field dean cv. Maris Bead were studied in potted plants plunged out doors in ash. At harvest time, all treatmemts had decreased plant height significantly due to the shortening of different internodes. Daminozide used at 5 leaf stage temprarily retarded growth and increased harvest idex. Later applications permanently retarded vegetative growth and increased HI. Daminozide used at 25-leaf stage increasd total dry weight and yield, All three treatments increased yield by increasing the number of pods per plant but did not influence single seed weight and seedsper pod.
