The symptoms of chilling and freezing injury of aubergine: When the chilling injury occurs at low temperature, the chlorophyll of the eggplant decreases, the roots grow stagnant, the plant grows slowly, the leaf margins and the tips of the leaves appear watery spots, and the leaf tissue becomes brown. In severe cases, the leaves wilted and died, the fruit was water-stained and softened, the fruit was dehydrated and shrunken, the fruit surface was sunken, and the flowers fell and fell. Low temperature chilling is aggravated by the decrease of temperature and the extension of low temperature. The daytime temperature is less than 17 degrees Celsius. The growth is slow. If the temperature is lower than 15 degrees Celsius, the fruit is dropped and the fruit set is stopped. If the temperature is lower than 10 degrees Celsius, the growth is stopped; the temperature will be minus 1 to minus zero. Cold damage occurs at two degrees Celsius.
Precautionary Measures: 1. Use of protective facilities that can ensure the normal temperature of eggplant growth. Second, the use of good cold-resistant varieties. Third, the cold period before the plants spray cold resistance, such as plant cold resistance.
