Seeds are the most basic means of production for agricultural production. The quality of seeds not only affects the performance of improved varieties, but also directly relates to the abundance of agricultural production. Germination rate is one of the most direct indicators of seed quality. Studying the factors affecting the seed germination rate has a great role in promoting the seed germination rate. The seed germination box is an important instrument for studying the influence factors of seed germination. The following is the result of our research.
Moisture: Seeds must absorb enough water to accelerate the physiological effects of the seeds, promote the activity of enzymes, facilitate the dissolution of storage nutrients and the growth of embryonic cells, thereby promoting the germination of seeds. Temperature: Temperature is the source of energy for seed germination. The role of temperature is to promote the activity of the enzyme. The optimum temperature for seed germination is the optimum temperature of the enzyme. In addition, the temperature also directly affects the speed of seed water absorption and respiratory strength. Within a certain temperature range, the higher the temperature, the faster the seeds absorb water, the stronger the respiration, and the faster the germination. Oxygen: When the seed germinates, the respiration is enhanced. If the seeds are anoxic, the seeds will not be suitable for germination. Illumination: Different crop seeds react differently to light when they germinate. Most crop seeds (such as corn, rice, and other cereals) do not require strict lighting. These seeds can be germinated with light or darkness.
It can be seen that the four factors that affect seed germination are the most important, namely, moisture, temperature, light and oxygen, and the former three factors can be controlled by the precise seed germination box. Because the precision seed germination box is a human-designed incubator that simulates the natural environment, it can provide suitable temperature, moisture, and illuminance at the same time. It is very suitable when studying the seed germination experiment.
