Abstract

The invention discloses a method for inducing parthenocarpy of pears. The method comprises the following steps of: at 1-2 days before a full-bloom stage, using inductive agent to process flower buds; and at the 5-7th day of the full-bloom stage, using the inductive agent to process flowers again, wherein the inductive agent is GA4+7 aqueous solution with the concentration being 200-500mg/L. According to the method, the parthenocarpy of the pears can be effectively induced, the parthenocarpy fruits have better appearance, no malformed fruits, high edible rate, small kernel, small core, no seeds, small fruit-to-core ratio, better flavor and high yield. In addition, the method has reasonable design, simplicity and convenience in operation, lower requirement on equipment, less cost, and large-scale operability, and can be demonstrated to be popularized and applied in commercial orchards.

Description

technical field [0001] The invention relates to the technical field of parthenocarpy, in particular to a method for inducing parthenocarpy in pears. Background technique [0002] Pear is a plant of the genus Pyrus in the family Rosaceae, a perennial deciduous fruit tree. The main varieties of pears are Qiuzi pears, white pears, sand pears and foreign pears, which are mostly distributed in North China, Northeast China, Northwest China and the provinces along the Yangtze River Basin. China is one of the birthplaces of the Pyrus plant center. Most of the pears of the Asian Pyrus genus originate in eastern Asia, and Japan and Korea are also the original origins of Asian pears. Pear is the "family of all kinds of fruits". Because of its tenderness, sweatiness, sweet and sour taste, it is also known as "natural mineral water". [0003] Parthenocarpy is the phenomenon that the ovary does not undergo fertilization to form fruit without seeds. Parthenocarpy can be divided into two ...
