Application of citrulline in promotion of fruit expansion and quality improvement of melon and fruit vegetables

Abstract

The invention discloses application of citrulline in promotion of fruit expansion and quality improvement of melon and fruit vegetables. The citrulline is applied to promotion of fruit expansion and quality improvement of melon and fruit vegetables. A fruit swelling agent for melon and fruit vegetables takes 2-200mg / L of citrulline as an effective component. The citrulline can be used for watermelon production in facility cultivation under weak light in early spring and autumn. Low temperature and weak light in spring and autumn seriously affect growth of watermelon plants and growth, development and expansion of fruits, and further affect yield and quality of watermelons. By exogenous spraying of the citrulline, growth of the watermelon plants can be remarkably promoted, the chlorophyll content and photosynthesis of the plants can be improved, so that expansion of the watermelon fruits is promoted, and meanwhile, the quality of the watermelon fruits is also remarkably improved. Meanwhile, the citrulline has no adverse effect on the environment, has no use risk of hormones and the like in production, is not limited by regions, and can be applied to facility watermelon production in spring and autumn.

Description

technical field [0001] The invention belongs to the technical field of application of biochemical reagents, and in particular relates to the application of citrulline in promoting fruit expansion and quality improvement of melons and fruits. Background technique [0002] Watermelon (Citrullus lanatus L.) is an important fruit crop, because it is rich in various nutrients such as carotenoids, sweet and juicy, and convenient to eat, it is deeply loved by consumers. Therefore, it is also a kind of Important vegetable economic crops. The cultivation area and output of watermelon in my country rank first in the world, and the total output can reach 70% of the world. Moreover, as people's demand for watermelon continues to increase, the cultivation area and output of watermelon in my country are still increasing year by year. One of the important means of increasing income. The size and weight of watermelon fruit are very important traits in agriculture, and are also an important...

Problems solved by technology

[0005] However, although citrulline is one of the important nutrients in watermelon fruit, and some studies have shown that citrulline in plants participates in plant stress regulation and promotes plant growth, but the use of exogenous citrulline in watermelon production applications have not been studied and reported
