Screening device for adverse-resistant plants

Abstract

The invention discloses a screening device for adverse-resistant plants. The screening device comprises a bracket, screening tanks, 96-well plates, a water storage device, a water pump and pipelines, wherein a first screening tank is arranged on an upper-layer fixing plate, a second screening tank is arranged on a lower-layer fixing plate, a water inlet pipe is arranged at the lower part of the water pump, the free end of the water inlet pipe extends to the bottom of an inner cavity of the water storage device, a water inlet pipe is arranged at the upper part of the water pump, the free end of the water inlet pipe extends to one end of the first screening tank, a first drainage pipe is arranged at the other end of the first screening tank, the upper end of the first drainage pipe is connected with the first screening tank, the lower end of the first drainage pipe is connected with one end of the second screening tank, a plurality of partition plates are arranged in inner cavities of the first screening tank and the second screening tank, a through hole is formed in one end of each of the partition plates, the through holes in adjacent partition plates are arranged in a staggered state, the 96-well plates are arranged at the upper parts of the partition plates, and a plurality of seed placing cavities are formed in the bottom parts of the 96-well plates. The screening device for the adverse-resistant plants disclosed by the invention can realize large-scale screening, and improves the screening efficiency of the adverse-resistant plants, and further has the screening characteristics of high accuracy, efficiency and controllability.

Description

technical field [0001] The invention relates to a screening device, in particular to a device for screening stress-resistant plants. Background technique [0002] Plant stress resistance refers to certain traits of plants that resist adverse environments. Adverse conditions such as drought, salinity, metal ions, and low temperature can severely inhibit plant growth and development, and cause changes in plant physiology, biochemistry, morphology, and even death. The adaptability and resistance of plants to adverse environments are stress resistance or resistance. The study of plant stress resistance has always been a hot spot in the field of agricultural science research. To carry out stress resistance research to improve the stress resistance of plants, especially food crops, It is of great significance to promote the development of agriculture and the improvement of ecological environment. [0003] In recent years, affected by global climate change, my country's extreme w...

Problems solved by technology

[0004] Due to the lack of an effective high-throughput method for accurate screening of stress-resistant plants, a large amount of screening materials are required for the screening of stress-tolerant plants, and different stress conditions are often required to be gradually provided, and the workload is huge. Therefore, there is an urgent need for an efficient and fast High Throughput Screening Methods
