Embodiment

[0021] Material collection method: select the seeds with full grains of the year, and wrap them with a damp cloth after picking;

[0022] Medium:

[0023] The MS basic medium was prepared using the formula in "Tissue Culture and Application of Woody Plants" published by Beijing Higher Education Press and edited by Chen Zhenghua in 1986.

[0024] The preparation of culture medium: basic medium is MS, add growth hormone to be BA, NAA, IAA, IBA, also add Su (sucrose) to be 20g / L in the medium, Ag + 7.5g / L, PH value is 5.8, the additive is activated carbon Ac; the thickness of the medium is generally 1.4 ~ 1.6cm;

[0025] Bud induction medium→MS+BA(1.0mg / L)+NAA(0.5mg / L)+IAA(1.0mg / L)+Ag + (7.5g / L)+Su(20g / L)+Ac(2~2.5g / L)

[0026] Bud Proliferation Medium→MS+BA(2.0mg / L)+NAA(0.3mg / L)+IAA(1.0mg / L)+Ag + (7.5g / L)+Su(20g / L)+Ac(2~2.5g / L)

[0027] Rooting medium→1 / 2MS+NAA(0.1mg / L)+IBA(0.5mg / L)+Ag + (7.5g / L)+Su(20g / L)+Ac(2~2.5g / L)

[0028] Ag in medium + Derived from AgNO 3 .

Abstract

The invention provides a method for embryo culture in vitro and plant regeneration of euscaphis konishii hayata, and belongs to the technique of culturing euscaphis konishii hayata embryo. The method solves the problems existing in the prior art that the seed germination rate of the euscaphis konishii hayata embryo is low, and well purified tissue culture seedlings cannot be provided in large amount. In the method, the full seeds in the same year are selected as materials, and the embryo undergoes induced culture for 15 to 20 days to grow strong seedlings; after proliferation for 20 to 30 days and induced rooting for 20 to 25 days, the seedlings are grown and transplanted, and the survival rate is as high as more than 95 percent; and the propagation factor is higher, and the survived seedlings are tall and strong, and well grown.

Description

technical field [0001] The invention belongs to the cultivation technique of the embryos of Crows rotundum, and more specifically relates to a method for cultivating and regenerating the isolated embryos of Crows sliver in vitro. Background technique [0002] Eascaphis kohlshli Hayata (Eascaphis kohlshli Hayata) belongs to the genus Eascaphis kohlshli Hayata, also known as Eascaphis kohlshli Hayata, Eascaphis kohlshli Hayata, and Eascaphis kohlshli Hayata. It is a unique native ornamental tree species in my country. It blooms in summer, bears fruit in winter, and has a long fruit period. When the red fruit matures, it cracks along the ventral suture. Together with its black seeds, it looks like a beautiful and lifelike red butterfly. It has great ornamental value and can be used as a landscape tree or street tree. The fruit-hanging time is very long, from the exocarp turning red to the peel off, the time is as long as half a year. Therefore, it can be viewed for a long time...
