Under what weather conditions will melons and fruits be sweeter? Under what weather conditions will melons and fruits be sweeter?

1, the greater the temperature difference, the stronger the respiration of fruits and vegetables, and the more sugar they secrete.

Because of the high temperature during the day, melons and fruits have a strong respiratory function. Therefore, organic matter will be produced inside the scraper, which will promote the secretion of sugar substances by fruits and vegetables. After the temperature drops sharply at night, the respiration of melons and fruits will be weakened accordingly, thus reducing the loss of organic matter in melons and fruits, thus realizing the accumulation of sugar in melons and fruits, resulting in the situation that the greater the temperature difference, the sweeter the planted melons and fruits will be.

2. Day and night

Large temperature difference is beneficial to improve the photosynthesis of fruits and vegetables, thus increasing the sugar content of fruits and vegetables.

The temperature difference between day and night also has a certain influence on the photosynthesis of melons and fruits. When the temperature is high during the day, fruits and vegetables receive strong sunlight, which is beneficial to the photosynthesis of fruits and vegetables, thus producing high-activity enzymes, so that scraping can decompose more sugar. However, the high temperature and strong light during the day have very high intensity on the growth of melons and fruits, so it is necessary to spend the relaxation period at night with low temperature. Moreover, when the temperature is too low at night, it is also beneficial to reduce the enzyme activity of fruits and vegetables, thus reducing the loss of sugar and preserving the sugar accumulated in fruits and vegetables during the day. Therefore, the greater the temperature difference between day and night, the higher the efficiency of plant photosynthesis.
