连续两年的试验结果表明:BAU-2对供试各品种(系)均有诱导雄性不育效果,不育率>95%;用0.2%,0.3%浓度的 BAU-2在小麦花粉的母细胞形成期至减数分裂期喷施效果最佳,人工饱合授粉结实率为53.0%,天然异交结实率为47.8%;喷药后,小麦抽穗推迟2～4天,株高略有降低。
The results of two consecutive years showed that BAU-2 had the effect of inducing male sterility on all tested varieties (lines), the male sterility was more than 95%. BAU-2 with 0.2% and 0.3% Spraying from cell formation stage to meiosis stage was the best, with artificial saturated pollination rate of 53.0% and natural outcrossing rate of 47.8%. After spraying, the heading stage of wheat was postponed for 2 ~ 4 days and the plant height decreased slightly .
