Embodiment 1

[0018] A method for breaking the dormancy of Torreya hainanensis seeds, the method comprises the following steps:

[0019] (1) Seed collection: select robust plants without pests and diseases, pick them with scissors when they are fully mature, soak them in cold water, scrub them with your hands, remove the peel and pulp, use water washing to remove residues, remove empty seeds, and screen out Seeds with plump and fully mature seeds are dried for later use;

[0020] (2) Remove the seed husk: Soak in clean water for 2 days, remove the seed husk after fully absorbing water;

[0021] (3) Soak the seeds of Torreya hainanensis in 20g / L potassium dihydrogen phosphate solution for 10 hours, then soak them in thiophanate-methyl 500 times solution for 1.5 hours, and finally wash the seeds with warm water at about 23°C, and then The cleaned seeds are added to the 100ml extract solution consisting of 20ppm gibberellin, 15ppm salicylic acid and 15ppm potassium nitrate, the remainder of t...

Abstract

The invention relates to a method for breaking the dormancy of Cephalotaxus mannii seeds. The method mainly comprises the steps of seed selection, seed soaking treatment, magnetic field treatment andlow-temperature stratification. Soaking and low-temperature stratification processes and other seed dormancy breaking processes are comprehensively utilized, so the germination period of the Cephalotaxus mannii seeds is greatly shortened, and seedlings obtained by using the obtained Cephalotaxus mannii seeds have prosperous roots, good growth vigor, fast speed and high survival rate.

Description

technical field [0001] The invention relates to a method for breaking the dormancy of Torreya hainanensis seeds. Background technique [0002] Hainan rough torreya (scientific name: Cephalotaxus hainanensis Li) is a tree of the family Cephalotaxus hainanensis, which can reach a height of 20 meters. Leaf blades are strip-shaped, arranged in two rows, apex slightly acute, acute or nearly acuminate, midrib raised above, stomata below. The seeds are usually slightly flat, with green arils before maturity and often red after maturity. It is a rare tree species unique to my country, and its distribution range is narrow, only found in Hainan, Guangdong, southeastern and western Yunnan, Rongxian County, Guangxi, and southeastern Tibet. Scattered in the forest. This kind of wood is solid and fine-grained, and can be used for construction, furniture, utensils and farm tools. Branches, leaves, and seeds can extract a variety of plant alkaloids, which have certain curative effects o...
