Problems solved by technology

Although warm water, sand storage and other treatments can increase the germination rate of unisexual magnolia seeds, the effect is not good. The highest germination rate is only about 60%, which cannot fully break the dormancy of unisexual magnolia seeds and shorten the time required for germination.

Embodiment 1

[0017] A method for breaking dormancy of unisexual magnolia seeds, the method comprising the following steps:

[0018] (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;

[0019] (2) Remove the seed husk: Soak in clean water for 2 days, remove the seed husk after fully absorbing water;

[0020] (3) Soak the unisexual magnolia seeds 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 composed of 20ppm gibberellin, 15ppm salicylic acid and 15ppm potassium nitrate, the remainder of the extract...

Abstract

The invention relates to a method for breaking the dormancy of kmeria septentrionalis seeds. The method mainly comprises the steps of seed selection, seed soaking treatment, magnetic field treatment and low-temperature stratification treatment. According to the invention, the technologies of soaking, low-temperature stratification treatment and the like for breaking the dormancy of seeds are utilized, so that the germination time of the kmeria septentrionalis seeds is greatly shortened, and the root systems of the kmeria septentrionalis seed seedlings obtained by the method are developed. In addition, the growth potential is good, the speed is high, and the survival rate is high.

Description

technical field [0001] The invention relates to a method for breaking the dormancy of unisexual magnolia seeds. Background technique [0002] Monosexual magnolia, an evergreen broad-leaved tree species belonging to the genus Monosexual Magnolia of the family Magnoliaceae, is 18m high and has gray bark. It is a national first-class protected plant in China. Distributed in Guangxi, Guizhou, in limestone mountain forests at an altitude of 300-500m. The tree species has a straight trunk and a beautiful tree shape, and is the preferred tree species for urban landscaping and building timber forests. [0003] Parthenosexual magnolia seeds begin to germinate about 100 days after sowing, and it takes more than 80 days to complete the germination process. Although warm water, sand storage and other treatments can increase the germination rate of unisexual magnolia seeds, the effect is not good. The highest germination rate is only about 60%, which cannot fully break the dormancy of ...
