Problems solved by technology

[0003] At present, the main method of propagating Zhongshan fir seedlings is cutting, which can keep the seedlings to maintain the excellent characteristics of the mother tree, but Zhongshan fir seedlings are lignified earlier, the survival rate of cuttings is low, and the number of seedlings is limited, the speed is slow, and the seedling production The rate is low, which restricts the large-scale popularization and planting of Zhongshan fir

Abstract

The invention relates to a rapid germination medium for the primary culture of Zhongshan fir, including an induction medium and a strong seedling medium; the medium provided by the invention is rich in nutrients, suitable for the proliferation and rapid germination of Zhongshan fir, and greatly shortens the cultivation time of Zhongshan fir. The cycle reduces the production cost; the germination rate of explants in the first generation of Zhongshan fir is more than 98%, the average germination time is less than 18 days, and the germination rate is fast; it can effectively reduce the browning rate of explants during tissue culture and increase the explant Implant survival rate, improve reproductive efficiency.

Description

technical field [0001] The invention relates to the technical field of Zhongshan fir tissue culture, in particular to a rapid germination medium for primary culture of Zhongshan fir. Background technique [0002] Zhongshan fir is a semi-evergreen tall tree with a tall and straight trunk and a beautiful tree shape. It is an excellent interspecific hybrid of three tree species: North American cypress, Mexican cypress, and pool fir. After years of experimental research by the Institute of Botany, Chinese Academy of Sciences, Jiangsu Province Selected and bred. It has the characteristics of long green period, fast growth, water and humidity resistance, salt and alkali resistance, strong wind resistance, less pests and diseases, wide adaptability, rapid growth, and excellent material quality than its parents. It is not only an excellent tree species for farmland forest network and tidal flat afforestation, but also presents broad development prospects in urban landscaping, water...
