摘要
用0.1%、0.3%、0.5%、0.7%和0.9%的硫酸二乙酯处理向日葵后,其发芽势、发芽率、出苗率、幼苗高度和细胞分裂指数均随着浓度增加而减小,染色体畸变率随浓度增加而提高。以平均苗的株高略高于对照苗株高的一半为指标,0.3%是向日葵较适宜的处理浓度。
With treated seeds of sunflower by DES, the ability and rate of germination,rate of emergence, seedling height and index of cell division all reduced, whereas the frequency of aberration of chromosome increased with the increase of DES concentration.The suitable concentration of DES was 0. 3% in sunflower seed.
