| 摘 要： | 在早熟禾的杂交中利用温汤去雄，从４５℃到４９℃，从１ｍｉｎ到５ｍｉｎ共设２５个组合，每个组合内又分去雄后直接套代和去雄后授粉２种处理，得出草地早离禾温汤去雄的最佳处理为４７℃、２ｍｉｎ，扁秆早熟禾（采集地天祝）的最佳处理为４８℃、１ｍｉｎ和４７℃、３ｍｉｎ

| Abstract: | Emasculation with hot water is widely used in the grass family, but it has hardly applied in herbage till now. In this paper, it was used in Poa breeding. From 45℃ to 49℃, from 1 min to 5 min, either bag or pollination 50 compositions was made, which indicate that the best composition is: 47℃、2 min for Poa pratensis, 48℃、1 min and 47℃ 、3 min for Poa pratensis L. var. anceps Gaud. |
