Robinia pseudoacacia cross-pollination isolation device

Abstract

The invention relates to a robinia pseudoacacia cross-pollination isolation device which comprises a supporting frame and an isolation bag, wherein the supporting frame comprises a clip and a supporting rod which are connected with each other; two annular hooks are arranged on the supporting rod and are used for fixing a robinia pseudoacacia inflorescence; two detachable supporting rings are arranged at the two ends of the supporting rod and are used for supporting the isolation bag; a V or U-shaped bayonet is arranged at a closed opening of the isolation bag, thus conveniently fixing the isolation bag to a branch. According to the device, a bag body can be fully isolated from flowers and is firmly fixed, and the influence on a plant pollination effect due to friction between the bag body and stigma and falling of a hybridization bag is eliminated. The device is pervious to light, breathable, rainproof, and convenient to dismount, store and transport.

Description

technical field [0001] The invention relates to a pollen isolation device used in the process of sexual reproduction of plants, especially in the process of artificially assisted sexual reproduction. Background technique [0002] Hybridization is the mating between two parents of different genetic composition, the resulting offspring are called hybrids. For forest tree species, hybridization usually refers to mating between different tree species or different varieties or types of the same tree species. Tree hybridization is a method of effectively integrating good genes, and it is an important and rapid means of cultivating new varieties in traditional breeding. Hybrids produced by hybridization may have excellent characteristics unique to both parents, and may be stronger than their parents in terms of growth vigor, productivity, or stress resistance, which gives breeding researchers room for choice and provides basic selection for the cultivation of new varieties Materi...

Problems solved by technology

[0007] The purpose of the present invention is to aim at the technical problem that the hybridization bag exists in the artificial cross-breeding process of black locust, to provide a kind of hybrid isolation device that can protect the inflorescence of black locust especially the stigma from damage. The inflorescence is fully separated, and the inflorescence of Robinia pseudoacacia can be fixed firmly, eliminating the friction between the bag body and the pistil, and damage to the stigma, which affects the pollination and fertilization of the plant; and the hybrid isolation device of the present invention is light-transmitting, air-permeable, rain-proof, and easy to disassemble. convenient and easy to store
