Male-seducing seed-reserving method during middle and later period of cucumber female plant growth

Abstract

The invention provides a method for inducing male flowers for seed reservation in the middle and late growing period of female strains of cucumbers, which is used in the breeding field of modern agriculture. Axillae parts where have flower bud primordium germinates on the main tendrils of the female strains of the cucumbers in the middle and later growing period are selected, the axillae parts aresprayed with silver nitrate to induce the germination of male flowers which are used for seed reservation after artificial pollination. The method of the invention relieves the restriction on pollination and fertilization on the high nodes of the female strains of the cucumbers for lacking of male flowers, and solves the problem that seed reservation is hard to realize through self pollination inthe middle and later growing period of the female strains of the cucumbers.

Description

technical field [0001] The invention relates to a method for saving cucumber seeds in the technical field of agricultural breeding, in particular to a method for attracting males and saving seeds in the middle and late growth stages of cucumber female lines. Background technique [0002] my country is the country with the largest cucumber production area and the highest total output in the world. In recent years, the introduction of foreign resources has provided many excellent breeding raw materials for cucumber breeding in my country. For example, using the characteristics of strong parthenocarpy and strong females of European and American cucumbers, we have bred our own female lines and used them in production. There are four types of sex types of cucumber plants: pure female type, strong female type, monoecious plant type, and oligogyne type. Pure female varieties are also called female lines. They have similar characteristics with strong female varieties. They all have...

Problems solved by technology

[0005] Aiming at the defects and deficiencies of the background technology, the present invention provides a method for attracting males and retaining seeds in the middle and later stages of growth of cucumber female lines, so as to overcome the previous limitation that artificial male induction of cucumber female lines can only be carried out in the early growth stage of the plants, and solve the problem of Difficulty in pollination and fertilization due to lack of male flowers in the middle and late growth stages of cucumber female line plants
