Embodiment 1

[0025] 1. Different concentrations of melatonin were sprayed on tomatoes in the green ripening stage (mainly divided into 5 concentrations of 0 μM, 1 μM, 50 μM, 100 μM and 500 μM, which were sprayed separately, and sprayed once every three days). Clean the tomato fruits in the green ripe stage just picked from the ground, select the fruits with the same size and color and divide them into 5 groups, each group has 10 fruits, and spray them with equal volumes of different concentrations of melatonin solutions respectively, at room temperature Place in the dark. (Each group has 3 repetitions, and the control group is the water treatment group). cut after 10 days, such as figure 1 shown by figure 1 It can be seen that the color of tomato fruit treated with 0 μM melatonin solution is blue-red; the color of tomato fruit treated with 1 μM melatonin is similar to that of the control, which is also blue-red; the color of tomato fruit treated with 50 μM melatonin is orange-red; The t...

Abstract

The invention relates to the cultivation of crops, and particularly provides a method for increasing the content of carotenoids in tomato fruits. According to the method, a melatonin solution with a concentration of 50-500 microns per liter is used for spraying tomatoes in a mature green stage. The experimental study results show that the spraying of the melatonin solution for the tomatoes in the mature green stage can increase the contents of alpha-carotene and beta-carotene in the tomato fruits significantly. The method is a non-transgenic technology, and is high in safety, high in efficiency, easy in operation and easy in promotion; the used melatonin solution has the characteristics of convenient preparation and biodegradability.

Description

technical field [0001] The invention relates to crop cultivation, in particular to a method for increasing carotenoid content in tomato fruit. Background technique [0002] With the continuous improvement of people's living standards, the level of pursuit of green and healthy food is also constantly improving. Coupled with the continuous strengthening of people's awareness of the harm caused by free radical imbalances in the body, the free radical scavenging and antioxidant capabilities of fruits and vegetables have gradually become prominent. The research on the antioxidant components and activities of fruits and vegetables has gradually become a focus of people's attention and research. [0003] Because carotenoids mainly exist in fresh vegetables and fruits, and animals and the human body cannot synthesize them by themselves, and the latest experiments also show that supplementing the human body with external chemically synthesized α- and β-carotene has no effect on huma...
