2,3,5——三碘苯甲酸(简称TIBA)是一种植物生长调节剂。1947年就有人开始研究它在大豆上的应用。经过多年研究证明,TIBA能够抑制大豆的顶端优势,加速植株下部花芽发育,使花芽增多,结荚数目也显著提高。1965年Anderson等将TIBA应用于大田,结果表明在大豆开花期喷施TIBA,使无限结荚型的大豆植株矮化,倒伏现象减轻,结荚增加而增产。1968年Cdviness报道,施用TIBA对有限结荚型大豆无增产效果。1974年Tanner指出,须在良好的生长条件下喷施TIBA才能增产。
2,3,5 - triiodobenzoic acid (referred to as TIBA) is a plant growth regulator. Someone started to study its use in 1947 in soybeans. After years of research, TIBA can inhibit the top edge of soybean, speed up flower bud development in the lower part of the plant, increase flower buds and increase the number of pods. 1965 Anderson and other TIBA will be applied to the field, the results show that sprayed at the flowering stage of soybean TIBA, infinite pod-type soybean dwarf plants, lodging reduced, increased yield pods. 1968 Cdviness reported that the application of TIBA did not increase the yield of limited pods. In 1974, Tanner pointed out that spraying TIBA under good growth conditions should increase production.
