摘要
观察了8个杂交优良沙棘无性系反映丰产性的单枝果实密度、百果重,反映抗旱性的落果率、果生长恢复率,反映丰产性和抗旱性综合表现的单株果产量,比较和评价了8个杂优沙棘丰产性和抗旱性的差异,给出了防落果,育大果,促高产措施的建议。
some key features had been observed to 8 hybrid seabuckthorn clones, the features including： the fruit density and weight of 100 berries witch reflect the high yield; the fruit abscission rate and the fruit growth recovery rate which reflect the drought resistance; the total yield of single plant which reflect the comprehensive performance. The differences of 8 hybrid seabuckthorn clones had been compared and evaluated on their yield and drought resistance. The suggestations have been put out for fruit droping prevention, measures for big fruit and high yield have been promoted too.
