Method for inducing kiwi fruit 'miliang-1' variety to produce seedless fruit through parthenocarpy

Abstract

The invention discloses a method for inducing kiwi fruit 'miliang-1' variety to produce seedless fruit through parthenocarpy and belongs to fruit tree growth of the technical field of agriculture. Mixed liquid in the method mainly contains four effective components of gibberellic acid, 2,4-D, amino acid and calcium with concentration being 60mg / l, 5mg / L, 100mg / L and 160mg / L respectively. The method includes that spray time is from 8-10 o'clock in sunny mornings when dew is dried in blow (in rainy days, the spray time is performed any time after rain stops and leaves are dried in blow) in the flowering phase of maliang-1 kiwi fruit and the wind is small; mist spray of the mixed liquid is performed for 4 seconds each time so that the liquid can be evenly sprayed on stigma of female flowers; the mixed liquid is only needed for once without repetition, so that marks are timely made after mist spray (such as hanging a tag or putting on red paint on sprayed branches); the situation that it does not rain within 2-3 hours after spray is good. The method is simple in operation and easy to master, the seedless fruit can be produced from the kiwi fruit 'miliang-1' variety through the parthenocarpy, quality is improved, yield is increased, and storage time is prolonged.

Description

Technical field: [0001] The invention belongs to the production of fruit trees in the field of agricultural technology, and in particular relates to a method for inducing parthenocarpy of the kiwifruit "Miliang No. 1" variety to produce seedless fruits. Background technique: [0002] Kiwi fruit is a dioecious plant, and artificial cultivation must plant male and female plants in a certain proportion. The traditional pattern is 8:1 planting, that is, 8 female plants with 1 male plant. However, recent studies have shown that it is better for male plants to be higher than this ratio. In fruit tree cultivation, phytohormones are used to induce parthenocarpy in female flowers to produce seedless fruits, which have been applied in strawberries, sweet oranges, grapes, etc., but have not been reported on kiwifruit. Compared with seeded fruit, seedless fruit has the characteristics of good quality, convenient eating, high edible rate, long shelf life, etc., and has higher applicati...
