In Kyoho grape, the shoots of 30-60cm in length at blooming period had the best fruit-setting. Shoots shorter than 30cm bore short clusters as well as condensed berries, therefore it took more labor on fruit thinning, and it resulted in smaller berries, lower sugar contents, bad coloring and worse fruit quality because the leaf-fruit ratio was not enough. A shoot that arised from strong pruning and of more than 60cm long at blooming could influence fruit setting and produced seedless berries, the distribution of berry was uneven so the appearance was poor. Furthermore, the shoot grew vigorously following fruit set and both of the shoot and fruit competed the nutrients so the berries grew slowly, therefore in the late stage of fruit growth the shoot grew over 200cm and the berries were smaller and poor colored. The proper shoot growth at blooming is 40-50cm long, which has good percentage of stopping of shoot tip at blooming and late stage of fruit growth and could improve fruit setting, berry growth as well as fruit quality.
