A kind of assay method of sunflower seed vigor

Abstract

The invention discloses a method for measuring the vigor of sunflower seeds. The method comprises: uniformly sowing sterilized sunflower seeds in a germination box with wet coarse sand at the bottom, covering the sunflower seeds with qualitative filter paper, and then covering the sunflower seeds with qualitative filter paper. Then cover the surface with a layer of wet coarse sand, and then place the germination box at 13°C for 2 days; take out the germination box after cultivation, and put it at 24-26°C for germination test. After 4-5 days of germination , count the germination rate of sunflower seeds through paper, and measure the vigor of sunflower seeds according to the germination rate of sunflower seeds through paper. The present invention combines low-temperature treatment and paper-through germination test to effectively simulate the adversity environment of sunflower field emergence, and through correlation analysis and regression analysis, it is found that there is a significant correlation between the paper-through germination rate obtained by the method of the present invention and the field emergence rate of seeds, It can accurately predict the emergence of seedlings in the field, and the results are accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of seed detection, in particular to a method for measuring the vigor of sunflower seeds. Background technique [0002] Seeds are the most basic means of agricultural production, and seed quality is the most important factor for seed safety. Improving seed quality is an important guarantee for high-efficiency, high-quality and high-yield agricultural production. Seed vigor is a general term that determines the potential ability of seeds (batches) to emerge quickly and neatly in the field and grow into normal seedlings, and is an important indicator of seed quality. High-vigorous seeds have obvious growth advantages and production potential, and are of great significance for improving seed storage tolerance and field seedling rate, resisting seedling adversity (low temperature, drought, pests and weeds, etc.), saving sowing costs, and increasing crop yield. High-vigorous seeds are an important guarantee for ...

Problems solved by technology

However, the use of this method has certain limitations due to the difficulty in obtaining brick and gravel particles, and it can only reflect the single soil topping ability of seeds and cannot simulate the complex environmental conditions in actual production.
