日光温室葡萄结果母枝粗度、芽位与新梢孕穗率的关系

摘要

The relationship between different diameters of bearing basal shoots, bud position and fruiting rate were studied on grapevine in greenhouse. The result showed that diameters of bearing basal shoots of Panjin and Zhuosexiang were 0.81~1.3 cm, both of bearing shoots rate and fruiting coefficient of shoots had higher level, when the diameter of new shoots were less than 0.8 cm which had less shoots, which exceed 1.31 cm had a lower level of fruiting rate. Zana, Victoria, Baifeng which the diameter of bearing basal shoots were between 0.8~1.4 cm, the rate of bearing shoot were 50%~100%, fruiting coefficient of shoots were 1.46~1.85. The diameter of bearing basal shoots on Red Globe were less than 0.7 cm, new shoots couldn't setting fruit, if the diameter of bearing basal shoots exceed 1.4 cm had a lower level of fruiting rate;Range 0.9~1.3 cm, there were which the shoot located on 5~8 bud position could show a ideal fruiting performance, shoot fruiting coefficient reached 0.986~1.318.%对日光温室的6个葡萄品种结果母枝的粗度、芽位萌发的新梢与孕穗率的关系进行了研究。结果表明，攀金和着色香以结果母枝粗度在0.81～1.3 cm时，母枝上的结果枝比率及新梢结果系数均较高，粗度小于0.8 cm时，抽生的结果新梢少，大于1.31 cm时，孕穗率又降低；乍娜、维多利亚和白峰结果母枝粗度在0.8～1.4 cm时母枝上的新梢结果枝比率达50%～100%，新梢结果系数为1.46～1.85；红地球葡萄结果母枝粗度小于0.7 cm，其上抽生的新梢不能孕穗，大于1.4 cm时，孕穗率又降低，母枝粗度在0.9～1.3 cm时，5～8节芽位上抽生的新梢结果性能较好，新梢结果系数为0.986～1.318。
