摘要
于晚秋梢萌芽前叶面喷布250~2000ppm多效唑,对5年生宫川温州蜜柑的晚秋梢控制具有良好作用,同时能增加枝条内可溶性糖、淀粉、钾及叶片中脯氨酸含量,降低细胞电解质外渗率,提高抗寒性。
Plant growth regulator, paclobutrazol, at the concentration ranging from 250~2000ppm was applied as foliar spray before budding of late autumn shoots in 5-year-old Miyagawa Wase (Citrus unshiu). Results showed that the growth of the late autumn shoots was inhibited and the content of soluble sugar, starch, potassium and proline in the autumn shoot was increased. Reduction of the exudate ratio of cell electrolyte may result in the increase of winter hardiness of the autumn shoots.
