Ilex dabieshanensis seed germination method

Abstract

The invention discloses an ilex dabieshanensis seed germination method. The method comprises seed pretreatment and seed germination treatment, wherein the seed germination treatment is to bury the pretreated ilex dabieshanensis seeds in wet sand to perform laminating treatment, wherein the laminating treatment comprises the following specific steps: (1) laminating and germinating in a dried sheltered cool environment of 20-30 DEG C for 50-60 days; (2) separating the seeds from the wet sand, and soaking the seeds in a treatment solution at the temperature of 15-25 DEG C for 4-6 hours, wherein the treatment solution comprises the following components: 300-400mg / LZnSO4, 100-150mg / L cytokinin and 200-250mg / L of ethylene; and (3) laminating and germinating the seeds soaked by the treatment solution with the wet sand at a low temperature of 1-5 DEG C for 100-130 days. According to the method disclosed by the invention, the seed activities are improved to the greatest degree, the seeds can be germinated within 180 days, and the germination rate can reach 36.7%.

Description

technical field [0001] The invention belongs to the field of plant breeding, and in particular relates to a method for accelerating germination of Dabie Mountain holly seeds. Background technique [0002] Holly belongs to the Ilex family Ilex, and is an evergreen tree. It has broad development prospects in landscaping, drug development, and materials. As an excellent landscaping tree species, it is named for its evergreen leaves all year round. In actual production, holly is commonly used for sowing and propagation, and cutting and tissue culture are also used. Although cutting and tissue culture can maintain the excellent traits of the breeding offspring and speed up the propagation speed, cutting propagation of holly plants is often difficult to root, and most of them are difficult to root. species. [0003] Regarding sowing and reproduction, because the seeds of holly trees have a dormant habit and have the characteristics of germination every other year, under natural ...

Problems solved by technology

[0004] For example, the patent of Application No. 201110211460.5 "A Stratification and Accelerating Germination Method of Ilex Ilex" discloses that the seeds of Ilex radix L. are directly mixed with wet sand in October-November and then dried in the shade outdoors for stratification until October-November next year. , take out the seeds and sow them on the hotbed, so that some of the seeds will germinate in white. Although the time required for this method is shorter than that of Ilex red-fruited dormancy, it still needs more than one year; Soak in warm water, then treat at low temperature for 15-20 hours, then soak in potassium permanganate, then soak in a mixed solution, and finally soak in clean water, put it in a sand bed for germination, but the invention does not disclose how to grow seedlings from sand bed germination time

[0005] "Emerald Coral" Dabie Mountain holly seeds are newly selected varieties in recent years. They are selected from wild Dabie Mountain holly. The method of germination treatment of "Emerald Coral" Dabie Mountain holly seeds
