Embodiment 1

[0015] The glucose powder, sucrose, soluble starch, and borax were pulverized respectively, passed through a 60-mesh sieve, and light calcium carbonate was passed through a 600-mesh sieve, and set aside. 25 parts by weight of glucose, 25 parts of sucrose, 49 parts of soluble starch, 0.5 part of borax and 0.5 part of light calcium carbonate are uniformly mixed to obtain the required composite pollen medium.

Embodiment 2

[0017] Example 1 was repeated, with the following differences: the composite pollen medium was prepared in proportions of 25 parts of glucose, 30 parts of sucrose, 45 parts of soluble starch, 0.5 part of borax, and 0.5 part of light calcium carbonate.

Embodiment 3

[0019] Repeat Example 1, with the following differences: the composite pollen medium is prepared in the proportion of 30 parts of glucose, 25 parts of sucrose, 45 parts of soluble starch, 0.5 part of borax, and 0.5 part of light calcium carbonate.

Abstract

The invention discloses a tobacco compound pollen medium and a preparation method thereof. The tobacco compound pollen medium is prepared by respectively smashing and evenly mixing the following components in parts by weight: 25-30 parts of glucose, 25-30 parts of cane sugar, 40-49 parts of soluble starch, 0.5 part of sodium borate and 0.5 part of light calcium carbonate. The tobacco compound pollen medium can promote the germination of the pollen and the elongation of pollen tubes, improves the fertilization success rate, improves the tobacco seed yield at per unit, and lowers the seed production cost of the tobacco seeds. The method of the invention has simple operation, low cost, popularization and application values and good economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of tobacco artificial pollination, specifically relates to a tobacco composite pollen medium, and also relates to a preparation method of the composite pollen medium. Background technique [0002] In the process of tobacco male sterile line and hybrid seed production, artificial pollination is an important and indispensable work. Due to the botanical characteristics of tobacco itself, a flower has only 5 stamens, the number of pollen grains produced is limited, and pollen collection is difficult. In production, it is often necessary to plant a large number of male parents and invest a lot of manpower to collect pollen to meet the pollination needs of the female parent. Therefore, pollen Collection is an extremely costly endeavor. At present, in the process of producing tobacco male sterile lines and hybrids, artificial pollination is mainly performed by using tobacco pure pollen or a single pollen medium mi...
