The formation of leaf surface of EKADA 113 soft spring wheat plants in Penza region with the usage of different growth regulators

For the first time photosynthetic activity of Ekada 113 spring soft wheat plants was studied in Penza region after the usage of the following growth regulators - ribav-Extra, epin-Extra, mival-Agro and kresacin. The results of the research proved that ribav-Extra and kresacin are contributing to leaf growth functions, that may serve as a basis for increasing plant productivity and may have some practical importance in some stressful environment (such as insufficient moisture supply) during the growing season.
