Some vegetable seeds undergo temperature fluctuations during the germination process. This method, known as temperature treatment, involves alternating between high and low temperatures to stimulate seed germination. The process typically involves placing the germinating seeds in a low-temperature environment of 1 to 5°C for 8 to 12 hours each day, followed by a period at a higher temperature range of 18 to 22°C for 6 to 12 hours. This cycle is repeated until the seeds fully germinate.
This technique helps the seeds adapt to temperature changes by adjusting the viscosity of their protoplasm, improving its ability to retain water. As a result, it enhances the cold tolerance of heat-loving plants like melons and nightshades, promoting better germination and stronger growth. It also accelerates the growth rate, leading to an earlier growth phase. Additionally, it strengthens the root system of seedlings, improving their resistance to low temperatures. This ultimately boosts the fruiting period of melon and fruit-bearing vegetables, increasing early yields and overall productivity. By using this method, growers can achieve healthier, more resilient plants that are better prepared for environmental challenges.
