| 摘 要： | 通过对6个薄壳山核桃无性系开花物候、花期长短、雌花开花数量以及雄花序数量等进行观测。结果表明,不同薄壳山核桃无性系雌雄花开花物候差异明显,6个无性系间雌花差异最长为10 d,差异最短为2 d;6个无性系间雄花差异最长为9 d,差异最短为1 d。6个薄壳山核桃无性系雌花、雄花序数量差异极显著(P<0.01),无性系21号、28号和104号雌花开放数量大,可以将其定为高产、丰产的主栽品种;无性系5号、27号、35号雄花序数量大,可以将其定为授粉品种,为其它花期相遇的无性系授粉用。根据试验的研究结果,无性系5号、27号、35号可以作为无性系21号、28号和104号的授粉品种。

| Abstract: | The flowering phenology,period of flowering phase,quantity of pistillate flowers,and the amount of staminate flowers were observed.The results showed that different clone Carya illinoensis had different flowering phenology.As to the flowering phase,the largest difference among the 6 clone pistillate flowers reached 10 days,and 9 days among the 6 clone staminate flowers.The smallest difference among the pistillate flowers was 2 days,and 1 day among the staminate flowers.There were significant differences among the quantity of pistillate flowers,as well as the amount of staminate flowers(P<0.01),clone No.21,28 and 104 had large quantity of pistillate flowers,which can be used as the main high yield breeds for planting.Clone No.5,27 and 35 had large amount of staminate flowers,which can be used as pollination breeds. |
