Method for detecting seed germination by fresh keeping bag

Abstract

The invention relates to a seed detection method, in particular to a fresh-keeping bag detection method for seed germination, comprising the following steps: soaking the seeds requiring the test method in water for 24 hours; laying absorbent paper on the drag tray; Sterilized water, the sterilized water is based on the fact that the accumulated water on the absorbent paper is not higher than half the height of the seeds to be tested; according to the size of the seeds, spread the seeds evenly on the absorbent paper with different numbers of seeds; transfer them into a fresh-keeping ziplock bag Inside, placed in a constant temperature box suitable for germination; detection and investigation are carried out according to the investigation indicators and time of the seed germination detection process. The fresh-keeping bag detection method for seed germination provided by the present invention requires sufficient water to be added at one time, and there is no need to replenish the water required for germination in the middle of the test; the transparent fresh-keeping ziplock bag can be directly observed for investigation without taking out the seeds for detection and investigation; at the same time, the required Less water, easy to operate, small storage volume, and can be concentrated to measure the germination of a large number of seeds.

Description

technical field [0001] The invention relates to a seed detection method, in particular to a fresh-keeping bag detection method for seed germination. Background technique [0002] Seed formation after sowing is the result of the interaction between seed quality and the environmental conditions of field emergence. After more than 100 years of predecessors' research and improvement, germination test has become one of the important inspection items of seed quality commonly used in all countries in the world, and it is used to estimate the emergence of seedlings in the field. At the same time, with the development of agricultural mechanization and the standardization of crop production, it is necessary not only to implement precision sowing, but also to build an ideal crop population. The requirements for high-vigorous seeds will become more and more urgent. [0003] Seed vigor refers to the potential of seeds to germinate rapidly and neatly and seedlings to grow robustly under ...

Problems solved by technology

For example, in the sand culture method, the sand needs to be cleaned and sterilized before the test. At the same time, more sand is required, and the germination box is large in size, etc., and the observation time is long and inconvenient. For example, the seedlings need to be removed from the sand during observation. Pull out the roots, this process is also prone to mechanical damage to the roots

There are disadvantages such as heavy measurement workload, poor repeatability, long measurement cycle, large environmental impact, and easy damage to seeds.
