Application of the spectrometric analysis for the estimation of soft wheat adaptive potential to conditions of the Northwest region of the Russian Federation
In the work the data according to reflectivity of spring soft wheat grades and lines, possessing various level of yield and resistance to the wheat powdery mildew agent is presented. The tool for the work was the active two-channel optical tester ADT-M. As the integrated plants condition indicator, the stress index (reverse vegetative index), which characterizes the degree of plant suppression, was used. The increase in a stress index values caused decrease in wheat yield (weight of 1000 grains, crop capacity, the flag leaf area), decrease in grains content of nitrogen, phosphorus, potassium and increased presence of powdery mildew agent. For use of the results in farming practice and plants protection a polynomial and exponential regression models, and also accounting scores, representing mentioned interrelations, were constructed.
