Fruit enlargement and quality improvement of the kiwifruit 'Hayward' by girdling
2016
Hayashida, S.
I investigated the influence of girdling of kiwifruit 'Hayward' in summer or autumn that gave to fruit enlargement, fruit quality, starch content of the mother branches and flower bearing of next year. And examined the most suitable girdling method. 1) Enlargement of the fruit was promoted by girdling for main stem in summer. In that case, girdling interval is from 20 days to 40 days in July or June at twice. The processing width to get an effect is 2.5mm enough. 2) A sugar content became higher by girdling for the beginning or middle of October that 50 days before harvest. The starch content of the mother branch became higher by girdling, and flowers bearing of next year increased.
