    Effect of Growing Conditions on Wheat Hormonal Status and Productivity in Experimental Ecological System / R. A. Karnachuk [et al.] // Russian Journal of Plant Physiology. - 2003. - Vol. 50, Is. 2. - P237-242, DOI 10.1023/A:1022933516663 . - ISSN 1021-4437

Аннотация: The levels of free and bound forms of IAA, ABA, cytokinins (CK), and gibberellins, as well as growth characteristics and productivity were investigated in two wheat lines. The plants were grown under controlled conditions in an artificial ecosystem that allowed the irradiance, CO 2 concentration, and rhizosphere temperature to be changed. The main difference in the hormonal status of leaves of tall spring wheat, line 232, and dwarf wheat, line 95-3, was the absence of GA9 gibberellins in the latter. It was found that the light intensity and temperature of rhizosphere insignificantly affected the balance of endogenous phytohormones and HI in wheat. The elevation of CO2 concentration resulted in a considerable increase in the content of free IAA, an appearance of free GA9, and a rise in the productivity of wheat, line 232. The concentration of CO 2 was shown to be a major parameter that determined HI in the experimental ecological system.

The main difference in the hormonal status of leaves of tall spring wheat, line 232, and dwarf wheat, line 95-3, was the absence of GA(9) gibberellins in the latter. It was found that the light intensity and temperature of rhizosphere insignificantly affected the balance of endogenous phytohormones and HI in wheat.
