摘要
１９９４～１９９７年，利用化学药剂处理小麦杂种Ｆ１及ＡＬ型不育系，诱导单性结实并探讨有关规律。结果表明：（１）不同化学药剂及小麦材料间诱导效果均呈极显著差异；（２）在小麦不同生育时期处理，以抽穗期诱导效果最佳；（３）花期重复处理，以连续处理４次的诱导结实率最高；（４）处理穗以下部结实最多，中、上部次之，顶部和基部最少。
Parthenocary of wheat has been induced by chemicals Since 1994.The results show:(1)The inducing effects vary evidently in different chemicals and varieties of wheat.(2)The inducing effect of heading stage is the best in growing period. (3)During florescence,the highest rate of set seeds was obtained by treating continually four times once per day. (4)In different parts of treated spikes, set seeds of the lower part is the most ,the middle and upper parts are fewer,the top and bottom are the fewest.
