Embodiment 1

[0032] Embodiment 1 A kind of evaluation method of solanaceous vegetables resistant to low light varieties

[0033] Evaluation index

[0034] The low light tolerance of tomato varieties was evaluated according to the seedling growth vigor index.

[0035] Detection method

[0036] Low light stress seedling growth experiment and non-stress seedling growth experiment, the specific operations are as follows:

[0037] 1) Select 120 tomato seeds for plug seedling cultivation, select 80 seedlings with the same growth potential when 3 leaves and 1 heart, and divide them into 2 parts, one part is used for weak light stress experiment, and the other part is used for non-stress experiment;

[0038] 2) Choose a solar greenhouse, divide it into two, separate it with plastic film in the middle, and cover half of it with a black sunshade net, so that the light intensity inside the greenhouse is reduced by 40% compared with that without the black sunshade net. It is used for weak light stre...

Abstract

The invention discloses a method for evaluating a low-light-resistant variety of solanaceous vegetables. The low light resistance of target tomato and pepper varieties is evaluated by using a seedlinggrowth vigor index under low light stress. By adopting the method, the low light resistance of the solanaceous vegetable varieties such as tomatoes and peppers can be evaluated quickly, accurately, scientifically and efficiently, feasible technical indexes and detection methods are provided for low light resistance screening of the solanaceous vegetable varieties such as the tomatoes and the peppers, and selection and application of the low light resistance varieties of the tomatoes and the peppers can be guided.

Description

technical field [0001] The invention relates to a method for evaluating low-light resistant varieties of solanaceous vegetables, belonging to the technical field of vegetables. Background technique [0002] With the continuous expansion of the area of ​​solar greenhouses in the northern region, the planting area of ​​solanaceous vegetables such as tomatoes and peppers in protected areas has also increased accordingly. Low temperature and weak light are the main problems faced by overwintering solanaceous vegetables in northern alpine regions. How to reduce the adverse effects of low light conditions in energy-saving greenhouses and greenhouses on the growth and development of tomatoes and peppers is a new topic for agricultural extension workers. . Selecting low-light-tolerant varieties is the most effective way to solve the low-light hazards of tomatoes and peppers. At present, the identification of low-light resistance of tomato and pepper is generally based on feeling a...
