3个猕猴桃品种花粉直感效应研究

为进一步研究猕猴桃花粉直感效应,选用I-3-2-2、I-1-5-3、I-1-6-5、I-1-15-4等4种花粉,分别给哑特、秦美、徐香猕猴桃雌株授粉,以自然授粉为对照,建立15个授粉组合。结果表明,猕猴桃在果实坐果率、单果质量、可溶性固形物含量、横径、纵径、果形指数、硬度、果实形状等方面表现明显的花粉直感效应,而在果柄离难易方面无花粉直感效应。通过果实平均单果质量、横径、纵径、果形指数、可溶性固形物含量、硬度等内外观性状的新复极差多重比较分析,得出不同花粉对猕猴桃果实影响差异较大。相同花粉在不同品种上授粉后表现有时相同有时不同。

Studies on pollen xenia of kiwifruit

Total of 4 kiwifruit pollinators,I-3-2-2,I-1-5-3,I-1-6-5 and I-1-15-4,were used for pollinating 3 female kiwifruit cultivars for studying the xenia. The 3 female kiwifruit cultivars,Yate,Qinmei,Xuxiang,were spontaneously pollinated as CK; 15 pollination combinations were made. The results showed that except on fruit stalk abscission,the pollen xenia obviously appeared on fruit-setting rate,fruit mass,soluble solids content,transverse diameter,longitudinal diameter,fruit shape index,flesh firmness and fruit shape. Statistical multiple according to the Duncan’s SSR,cross-pollinated fruits showed significant difference in average fruit mass,transverse diameter,longitudinal diameter,fruit shape index and flesh firmness. However,different cultivars pollinated by same pollen showed significant difference,sometimes the same,or sometimes not.
