Abstract

The invention discloses a solid culture medium for culturing garlic epigamous embryo, belonging to the field of agricultural biotechnology. The solid culture medium includes the following components: potassium nitrate, ammonium nitrate, monopotassium phosphate, magnesium sulfate, calcium chloride, potassium iodide, boric acid, manganese sulfate, zinc sulfate, sodium molybdate, copper sulphate, cobalt chloride, ferric sulfate, sodium ethylene diamine tetracetate, cyclohexanehexol, nicotinic acid, puridoxine hydrochloride, thiamine hydrochloride, glycin, coconut cream, sucrose, 6-benzylamino adenine or zeatin, indoleacetic acid or rhodofix and agaragar. The solid culture medium for culturing garlic epigamous embryo has the advantages of good culturing effect and high success rate; based on the original foundation, the planting percent is increased by more than 30% and the propagation coefficient is improved by two times, thus greatly improving the culturing success rate of the garlic epigamous embryo or the whole plant thereof and solving the key technology of the difficult problem that the garlic can not be reproduced sexually.

Description

technical field [0001] The invention relates to a solid medium for cultivating garlic embryos, which belongs to the field of agricultural biotechnology. Background technique [0002] Garlic (A. Sativum L.) is a spicy vegetable of the Liliaceae. It is an important useful vegetable. It is not only used as a condiment in large quantities, but also developed as a health food and medicine, which can excite nerves, increase appetite, and It has certain functions of sterilization, disease prevention and treatment, and has high edible and medicinal value. [0003] However, in production, due to the abortion of garlic flowers under conventional cultivation conditions, normal seed formation and sexual hybridization cannot be carried out, so it has been possible to rely on garlic bulbs for asexual reproduction for a long time. The reproduction coefficient is very low, the amount of seeds used is large, and the production cost is also high. At the same time, the genetic background of ...
