中华猕猴桃雄性营养系选配的研究

STUDIES ON SELECTION OF SUITABLE MALE STRAIN FOR FEMALE VARIETY 'LQ-8'OF ACTINIDIA CHINENSIS

对中华猕猴桃三个雄性系的花期、花量、花粉生活力、花粉量和雄花开花的时间进行了观察,分析了用不同雄株授粉于雌性品种‘LQ—8’.对果实外观、品质和种子的影响.结果表明:‘开雄’雄株有效花粉量最高;用‘杭雄’授粉.其雌株‘LQ—8’果实单果重、碳水化合物明显低于‘开雄’和‘白花岩82—3’授粉;顶花明显优于侧花,一朵雄花的有效花期一般只有3天,经试验认为‘开雄’为雌性品种‘LQ—8’的适配雄株.

In this paper,flowering dates,the quantity of flower,the number andviabitity of pollen ect.of three male strains were investigated and compared,the effects of the different male pollenizers on fruit appearance,qualityand seed of a variety‘LQ-8’were studied.The results showed that theyeild of effective pollen per flower of‘KH-Y’male strain was highest;Thefruit of‘LQ-8’pollinated with‘HZ-Y’male strain was obviously smallerin the weight and lower in the total sugar contents than two others,andfruit-shape,ripen-date,contents of organic acid and Vitamin C were notdistinctly affected by male pollenizers.It was suggested that‘KH-Y’malestrain was the best pollinator for the female variety‘LQ-8’.The affinityand xenia were discussed.
