摘要
研究了3年生葡萄杂交苗结果母枝粗度、留芽量与花芽分化的关系。结果表明,杂交后代植株结果母枝粗度为0.79~1.20 cm时,新梢结果系数达0.900以上,结果枝率达60%以上;结果母枝粗度为0.89~0.98 cm时,花芽分化最好,可达71%。葡萄杂交苗花芽分化集中分布在结果母枝第5~9芽,其中6~8芽是花芽集中分布的部位,平均分化率可达40.6%。
The relation between the diameter of fruit cane,leave bud quantity and flower bud differentiation of 3 years old grape hybrid seedlings was studied. The results shows that in order to have ideal fruiting rate,the fruiting cane should be in a suitable diameter. When fruiting cane diameter in 0.79~1.20 cm,Shoot fruiting coefficient is above 0.900,Shoot burliness ability above 60%;When fruiting cane diameter in 0.79~0.98 cm,flower bud differentiation is best,can reach 71%. The leave bud quantity has an appropriate range at the 5~9 bud of grape fruit cane,flower bud differentiation is centralized distribution at the 6~8 nodes,the average flower bud differentiation rate was 40.6%.
