EFFECTS OF PLANT VIGOR ON FRUIT SIZE AND QUALITY AND FLOWER PRODUCTION IN KIWIFRUIT

J. Cai, Z. Wang
This study investigated the relationship between plant vigor and fruit size and quality and flower production of two kiwifruit cultivars, A. chinensis ‘Cuiyu’ and A. deliciosa ‘Miliang-1’. Results showed that plant vigor was a key factor affecting fruit growth and development and the number of flowers the following year. For both cultivars, fruit from strong plants were bigger than those from weak plants. Fruit from strong and medium strength plants had similar SSC, and storability was better. And stronger plants produced more flowers than weaker plants in the following year. The proportion of long shoots (≥100 cm) in the current year can be used as an indicator to evaluate the plant vigor at the end of the shoot growing season. For both cultivars, a vigorous plant should have about one third long shoots. Proper techniques in orchard establishment, fertilizer application, pruning and fruit thinning should be applied in order to enhance plant vigor.
