INFLUENCE OF TEMPERATURECONDITIONS ON THE DEVELOPMENT PHASES OF VARIETIES AND RIDGES OF DURUM WHEAT

Аннотация

Today in the world 220 million hectares of land are planted with crops, most of which are affected by abiotic factors. Wheat can be exposed to heat at any stage of development. The average air temperature for wheat growth and development is +18 + 25 oC, which begins to have a negative effect when it exceeds +32 oC. An increase in air temperature above +32 oC has a strong effect on the reproductive organs and has a strong negative effect on the process of grain filling in the middle and late stages of development.
