ＢＡ能促进水稻超丰早１号（高粱稻）种子苗的发生，在０．５～２．５ ｍｇ·Ｌ－１浓度下，配以 ２，４Ｄ促使多分蘖，形成“多芽蘖”（芽蘖为胚芽腋芽或第１叶叶腋的叶芽）。黑暗中生长时，节间伸长，叶基部发生多芽蘖和次生腋芽，数目有３～７个不等。先照条件下，节间伸长不明显，虽有多芽蘖发生，但数略少，芽蘖由茎基部发生侧芽，也可由侧芽再分裂形成。
BA can promote the seedling emergence of the rice variety “Super Fengzao 1” (sorghum rice). When the concentration of 0.5-2.5 mg · L-1 was combined with 2,4D, the multi-tillering was promoted to form “multi-shoot tiller” Bud tillers axillary bud germ or leaf axils of the first leaf bud). When growing in the dark, the internodes elongate, with more sprouts and secondary axillary buds at the base of the leaves, ranging from 3 to 7 in number. Under the first condition, the internode elongation is not obvious, although there are many sprout tillers, but the number of slightly less, the bud tiller occurs from the base of the lateral bud bud, but also by the side bud re-division formed.
