Method for releasing dormancy of solanum torvum swartz seeds

Abstract

The invention belongs to the field of crop seed treatment, and particularly relates to a method for releasing dormancy of a solanum torvum swartz seed. The method comprises performing variable temperature germination processing of the seed, that is, cultivating the seed at a first temperature and cultivating the seed at a second temperature to obtain a germinative seed, wherein the first temperature is in a range of 18-22 DEG C, and the second temperature is in a range of 33-37 DEG C. According to the invention, the seed is subjected to variable temperature processing, and only temperature and light conditions need to be changed, without any chemical substance or hormone for processing, so that the method is simple to operate, and the cost is saved. Under the synergistic effect of temperature and light conditions, the germination rate of the seed is raised.

Description

technical field [0001] The invention belongs to the field of crop seed treatment, and in particular relates to a method for dormant release of eggplant rootstock seeds. Background technique [0002] Eggplant (Solanum melongena L.) is an annual or perennial herbaceous plant with berries in the Solanaceae Solanaceae Solanum genus Solanum. It originated in the tropical south of Asia, and ancient India was its earliest domestication place (Li Zhiliang et al., 2006). It has a long history and is the second origin of eggplant, with rich eggplant germplasm resources (Zhang Nian et al., 2013). Eggplant is the fourth largest vegetable crop in the world, and it is also one of the main types of vegetables in my country. my country is the largest eggplant producer in the world (Li Zhiliang et al., 2006). It has high yield, strong adaptability, and long fruiting period. It is the main vegetable in summer and autumn. It is favored by consumers because of its rich nutrition and high medic...

Problems solved by technology

[0003] The eggplant planting area is wide, but there are continuous cropping obstacles

For heavy cropping, soil-borne diseases are extremely harmful, especially Verticillium wilt, Fusarium wilt, and bacterial wilt. The mild ones lead to a 30% to 40% reduction in yield, and the severe ones have no harvest (Lin Guirong et al., 2005). Over the years, the problem of "heavy cropping" has been Troubled farmers, planting eggplants has become a one-shot deal. They have just become familiar with eggplant planting techniques, but they have to give up and switch to other crops, seriously affecting the development of the eggplant industry.

[0006] Existing studies have shown that chemical substances and exogenous hormone treatments can increase the germination rate of Torubum seeds, promote germination, and break dormancy, but which chemical substance or hormone treatment has the best effect and what is the appropriate treatment concentration? Opinions vary, inconclusive

Moreover, the quality of chemicals and hormones produced by different manufacturers is different, and the treatment effects are different. More experiments are needed to prove the actual production.
