Embodiment 1

[0026] In this example, pepper seedlings are used as the research object, and by measuring relevant physical and chemical indicators, the regulatory effect of exogenous GABA treatment on pepper seedlings under low light stress is clarified. The specific implementation plan and results are as follows:

[0027] In this embodiment, pepper seedlings are used as research objects, and they are sown in a solar greenhouse. After the seeds germinate, they are sown in a nutrient bowl, and the experimental materials are placed in an artificial incubator with peat soil as a substrate. The photoperiod was set as 10h / 14h light. In this experiment, six experimental treatments were designed, each treatment included 10 seedlings, and each treatment was repeated three times. A total of 6 concentration gradients of exogenous GABA were set up, which were prepared into aqueous solutions with concentrations of 5mM, 20mM, 35mM, 50mM, 65mM, and 80mM before use. Use a small watering can to spray eve...

Abstract

The invention discloses a method and an application for improving weak light resistance of nightshade crops, and belongs to the technical field of vegetable cultivation. The method is characterized in that the crops are treated by a GABA (gammer amino butyric acid) solution under a weak light condition. The method has the advantages that by using the GABA as a growth regulating agent, the adaptability of the crops to weak light stress is improved, the weak light resistance ability of the crops is improved, the photosynthetic efficiency of the crops is improved, and the adverse effect of adversity stress to the crops is relieved; the manual light supplementing operation is safely and efficiently replaced, the important meaning is realized for the actual production, and a theoretical basis and reference are provided for breeding of high-quality weak light-resistant pepper variety.

Description

technical field [0001] The invention relates to a method and application for improving solanaceae crops to cope with weak light growth environment, and belongs to the technical field of vegetable cultivation. Background technique [0002] Solanaceae crops mainly include tomato, pepper, eggplant and other vegetables. These crops mostly originate in tropical and subtropical regions of Central and South America, so they have very similar physiological characteristics and cultivation requirements, especially for high light intensity and temperature. , is a kind of vegetable crop with huge cultivated area in the world. At present, the off-season cultivation area of ​​chili peppers in domestic facilities has shown explosive growth. Compared with the normal production conditions in the open field, the facility environment often has reduced light intensity due to the existence of mulch and skeleton structures, and the light intensity and time in winter and spring are obviously insuf...
