Problems solved by technology

The conventional method of selecting stress-resistant crop varieties not only requires specific stress conditions, but also needs to measure multiple growth and development indicators as well as physiological and biochemical indicators. also not comparable
Especially when comparing strains, it is necessary to obtain the yield and stress resistance information of the strains at the time of harvest, which also has a serious impact on the expansion and generation.

Embodiment 1

[0185] Example 1 Pick potato plants greater than 5 leaf stages and in the growth stage at the experimental field of Agricultural Vocational College in Qingzhen, Guiyang, and return to the laboratory quickly. After cleaning the surface dust of the leaves on the plants, collect the second one from the plants respectively. Expand the leaf to the fourth unfolded leaf as the leaf to be tested, put it in distilled water and soak for 30 minutes; blot the water on the surface of the leaf, and immediately clamp the leaf to be tested between the parallel electrode plates of the measuring device, set the measuring voltage and frequency, and change the iron Different clamping forces are set according to the quality of the block, and the crop leaf physiological capacitance, physiological resistance and physiological impedance under the parallel mode are measured under different clamping forces; Utilize the present invention, with the second expanded leaf of the first plant of Potato Feureta ...

Abstract

The invention discloses a method for selecting stress-resistant crop varieties based on electrophysiological characteristics, and belongs to the technical field of crop breeding. By measuring the physiological capacitance, physiological resistance and physiological impedance of crop leaves under different clamping forces, the physiological capacitance and physiological reactance of crop leaves are further calculated; the physiological capacitance, physiological resistance, physiological impedance, physiological capacitance and physiological resistance of crop leaves are constructed respectively. Using the parameters of these models to calculate the specific effective thickness, inherent physiological resistance, inherent physiological impedance, inherent physiological capacitive reactance and inherent physiological inductive reactance of crop leaves, and then calculate the metabolic energy of crop leaf cells and the relative persistence of crops. Water time, crop low nutrient tolerance, crop nutrient utilization efficiency, normalize the above indicators, comprehensively evaluate the scores of each sample to be tested, and quantitatively compare the pros and cons of the tested varieties with the average value of the comprehensive score.

Description

technical field [0001] The invention belongs to the technical field of crop breeding, and specifically relates to a method for selecting stress-resistant crop varieties based on electrophysiological characteristics, which can not only quickly and online quantitatively detect the comprehensive ability of different crop material metabolism and energy metabolism, but also screen high-yield and stress-resistant crop varieties. The results of the measurement are comparable, and biophysical indicators can also be used to characterize the adaptation characteristics of different crops to drought and low nutrition, which greatly improves the efficiency of crop variety selection, reduces costs, and provides technical support for intelligent breeding. It is an important component of smart agriculture. part. Background technique [0002] Stress-resistant crop varieties refer to crop varieties that can obtain high yield in adversity. Common stress-resistant varieties are characterized by...
