Rapid screening method for identifying cold resistance of tomatoes and application

Abstract

The invention belongs to the technical field of tomato cold resistance identification, and discloses a rapid screening method for identifying cold resistance of tomatoes and an application; the rapidscreening system comprises a video monitoring module, a temperature detection module, a main control module, a culture module, a sterilization module, a watering module, a cold treatment module, a conductivity measurement module and a display module. According to the invention, a plurality of mixtures are adopted to prepare the culture medium, so that the fertilizer is better suitable for the growth and development of tomatoes; meanwhile, by utilizing the relative conductivity of isolated leaves, the damage degree of the low temperature to the cell membranes can be reflected, and by combiningthe recovery growth experiment after cold injury, the direct tolerance capability of the cells to the low temperature injury is identified, and the growth recovery capability of the material after thelow temperature is released is identified.

Description

technical field [0001] The invention belongs to the technical field of tomato cold resistance identification, and in particular relates to a rapid screening method and application of tomato cold resistance identification. Background technique [0002] Tomato, that is, tomato (scientific name: Lycopersicon esculentum Mill.), is an annual or perennial herbaceous plant of Tubularfloweres, Solanaceae, Tomato genus, with a body height of 0.6-2 meters. Easy to lodging, leaves pinnately compound or pinnately parted, peduncle 2-5 cm long, often 3-7 flowers, calyx radial, corolla radial, berries oblate or subglobose, fleshy and juicy, Seeds yellow, flowers and fruits in summer and autumn. Tomatoes are native to South America and are widely cultivated in northern and southern China. Tomato fruit is rich in nutrition and has a special flavor. Can be eaten raw, cooked, processed tomato paste, juice or whole fruit canned. However, the tomato planting fertilizers used in the existing ...

Problems solved by technology

However, the tomato planting fertilizers used in the existing tomato cold resistance identification process are not good for tomato growth; at the same time, the traditional method of screening and identifying tomato germplasm resources with excellent cold resistance traits by relying on natural cold climates has a large amount, a long period, and a long period of time. Instability and other disadvantages

[0003] In summary, the existing problems in the prior art are: the tomato planting fertilizers used in the identification process of the existing tomato cold resistance are not good for tomato growth; meanwhile, the traditional method of screening and identifying tomato germplasm with excellent cold resistance traits is based on the natural cold climate approach. The resource method has disadvantages such as large amount, long cycle, unstable traits, etc.

When the temperature sensor is used to detect temperature data, the error is large
