Artificial emasculation and hybrid control pollination method of robinia pseudoacacia L.

Abstract

The invention discloses an artificial emasculation and hybrid control pollination method of robinia pseudoacacia L.. The method comprises the following steps of pollenator making, selection of hybrid male parent and female parent plants, pollen collecting, artificial pollination, pollinated female plant management and hybrid ripe pod harvesting. According to the artificial emasculation and hybrid control pollination method of the robinia pseudoacacia L., the technical steps of emasculation and pollination for the robinia pseudoacacia L. are described in detail, petals and pistil are not damaged, the artificial pollination ripening rate of the robinia pseudoacacia L. can be significantly increased, and the artificial hybridization breeding success rate of the robinia pseudoacacia L. is increased.

Description

Technical field

[0001] The invention belongs to the technical field of plant breeding, and specifically relates to a method for artificial emasculation and hybrid controlled pollination of black locust. Background technique

[0002] Robiniapseudoacacia L. is a large broad-leaved tree of the Fabaceae subfamily Papilioideae. It is native to the United States and was introduced to Europe in the early 17th century (1601). By the 18th century, it spread throughout Europe. The Germans first introduced black locust seeds to Qingdao, China, at the end of the 19th century. From the 1940s to the 1960s, several batches of black locust seeds from Japan, the United States, and North Korea were planted in Liaodong, Tianshui, Gansu, Changsha, Hunan, and North China. In the late 1980s, 24 provinces, municipalities, and autonomous regions in China planted black locust trees. Only 6 provinces, including Hebei, Henan, Shandong, Shanxi, and Liaoning, had 4 billion trees, making it the most popu...
