Abstract
The application provides a method for improving nutrient supply of female floral branches of Populus deltoides artificial hybridization. According to the technical links of the hybridization operation, the method separately integrates and improves the cultivation of female floral branch nutrient-supply seedlings (i.e., grafting rootstocks of floral branches), the pre-management of female floral branch nutrient-supply seedlings, the hydroponic management of floral branches, the Marching between female floral branches and rootstocks, the management of female floral branch nutrient-supply seedlings and the hydroponic management of female floral branches, so the goal of improving the seed-setting rate and quality of poplar hybrid seeds which came from the floral branches cultured in water has been achieved. Compared with the conventional method, the method of the invention not only can realize good seed quality, but also improve the seed-setting rate, and has a remarkable effect when applied to Populus deltoides artificial hybridization.
