Embodiment 1

[0032] Embodiment 1 A kind of evaluation method of solanaceous vegetables low-temperature resistant varieties

[0033] Evaluation index: Evaluate the low temperature tolerance of tomato varieties according to the seed vigor index.

[0034] Detection method

[0035] Suboptimal temperature stress germination test: randomly select 30-40 tomato seeds to be evaluated, disinfect with 10% sodium hypochlorite solution for 20 minutes, rinse with tap water 3 times, and place them flat on a petri dish (Φ9am) covered with 1 layer of filter paper. Add 7 mL of distilled water to the petri dish, put it into an artificial climate box at a temperature of (18±1)°C, and germinate under dark conditions. Regularly observe and replenish distilled water every day. Record the situation of germinated seeds every day, and the seeds whose radicle breaks through the seed coat by 2mm are germinated seeds; measure the radicle length v of germinated seeds on the 14th day, and the radicle length of ungermi...

Embodiment 2

[0061] Embodiment 2 A kind of evaluation method of solanaceous vegetables low-temperature-resistant variety

[0062] Evaluation index: Evaluate the low temperature tolerance of pepper varieties according to the seed vigor index.

[0063] Detection method

[0064] Suboptimal temperature stress germination test: randomly select 30-40 capsicum seeds to be evaluated, sterilize with 10% sodium hypochlorite solution for 20 minutes, rinse with tap water 3 times, and place them flat on a petri dish (Φ9am) covered with 1 layer of filter paper. Add 7 mL of distilled water to the petri dish, put it into an artificial climate box at a temperature of (18±1)°C, and germinate under dark conditions. Regularly observe and replenish distilled water every day. Record the situation of the germinated seeds every day. The germinated seeds break through the seed coat with the radicle not less than 2mm. Measure the radicle length v of the germinated seeds on the 16th day. The radicle length of the ...

Abstract

The invention discloses a method for evaluating low-temperature-resistant varieties of solanaceous vegetables. The low-temperature-resistant degree of target tomato and pepper germplasm is evaluated by using a seed vitality index under suboptimal temperature stress. By adopting the method, the low-temperature resistance of 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-temperature-resistant screening of the tomato and pepper varieties, and selection and application of the low-temperature-resistant varieties of the tomatoes and the peppers can be guided.

Description

technical field [0001] The invention relates to a method for evaluating low-temperature resistant varieties of solanaceous vegetables, belonging to the technical field of vegetables. Background technique [0002] The main problem faced by overwintering solanaceous vegetables in northern alpine regions is low temperature and weak light. Especially during the critical production period, the temperature in the greenhouse is low. When the average daily temperature is below 10°C, the growth of tomatoes and peppers will be severely restricted. Selecting low temperature resistant varieties is the most effective way to solve the low temperature damage of tomato and pepper. At present, the identification of the low temperature resistance of tomato and pepper is generally based on feeling and experience, and there is a lack of scientific and practical methods. Therefore, it is extremely necessary to establish a set of rapid and accurate evaluation methods for low temperature tolerant...
