摘要
为了给猕猴桃花果管理和果实适时采收提供理论依据,并为制定科学的猕猴桃栽培技术和管理措施提供参考,连续3a(2009～2011年)对猕猴桃不同结果部位的果实产量和质量进行研究。结果表明:在结果母蔓上顶芽、次芽和三芽等形成结果蔓的果实单果重、产量之间都存在差异显著水平;果实含糖量之间不存在差异显著水平,其大小顺序,次芽蔓果>顶芽蔓果>三芽蔓果;果实后熟时间,顶芽蔓果>次芽蔓果>三芽蔓果。在树体上部结果母蔓、中部结果母蔓和下部结果母蔓的果实单果重、产量之间都存在差异显著水平;果实含糖量之间不存在差异显著水平,其大小顺序为中部果>下部果>上部果;果实后熟时间,上部果>中部果>下部果。在结果蔓上第1、2、3节位果与第4节位果的单果重之间存在差异显著水平,而前3节位果实单果重相互之间不存在差异显著水平,第2节位与第1节位的果实产量之间不存在差异显著水平,第1节位与第3节位的果实产量和第3节位与第4节位果实产量之间都存在差异显著水平;果实含糖量之间不存在差异显著水平,其大小顺序,第3节位果>第4节位果>第2节位果>第1节位果;果实后熟时间,第1节位果>第2节位果>第3节位果>第4节位果。可见不同结果部位直接影响着果实的单果重、产量和果汁含糖量,也影响着果实在后熟过程中的单果失重率、果形指数和后熟时间等的变化程度。建议在猕猴桃生产上把不同结果部位作为疏花疏果和判断猕猴桃果实成熟的重要依据之一,为制定科学的猕猴桃栽培技术和管理措施提供参考。
In order to give the flowers and kiwi fruit harvested management and timely provide theoretical basis, and for making scientific kiwi fruit cultivation techniques and management measures for reference, from 2009 to 2011, the influence of different fruit part on yields and quality of kiwi fruit between terminal bud,time bud and the third bud were studied. The results showed that the fruit yield and quality between the crown, time shoots mother and three had significant differences and there was no significant difference between sugar content,the order were,time buds terminal bud the third bud;after ripening order were,terminal bud time bud the third bud there were significant difference between the upper mother tendril,the central mother tendril and the lower mother tendril on fruit yield and quality,and there was no significant difference between sugar content, the order were the central mother fruit the lower mother fruit the upper mother fruit during after ripening was the upper mother fruit the central mother fruit the lower mother fruit there were significant difference of the first,second,third quarter of fruit tendril between the fourth quarter of fruit tendril on weight, there was no significant difference between the former three treatments, and there were no significant difference between the first and second fruit tendril on fruit weight, but had significant difference between first and third, and the third and fourth quarter of fruit tendril on yields, there was no significant difference of sugar content, the order was,the third quarter of fruit tendril^fourth quarter of fruit tendril the second quarter of fruit tendril^first quarter of fruit tendril after ripening order was,the first quarter of fruit tendril the second quarter of fruit tendrilS〉the third quarter of fruit tendril 〉 fourth quarter of fruit tendril. It was easy to know different fruit part significantly influenced single fruit weight, yield and fruit sugar, also affected the fruit weightlessness rate, shape index and after ripening time. This paper ad~,ised different fruit parts as one of the important basis for thining flowers and fruits,and for judgment of the ripening time of kiwi fruit,to provide scientific cultivation technology and management measures on kiwi fruit.
