Abstract

The present study was designed to investigate the influence of gibberellin (GA) priming under vernalization on the growth response, content and fractional composition of soluble carbohydrates in seedlings of 3 varieties of winter wheat - Doridna, Statna and Alians. Modeling different levels of trophic support of the vernalization process and investigating the influence of GA, the following variants were used in the experiments: 1) grains + water (control, optimal trophic support); 2) grains + 10 mg / l GA3, (optimal trophic support); 3) isolated embryos + water (control, lack of trophic support); 4) isolated embryos + 10 mg / l GA3 (lack of trophic support). Vernalization was carried out during 45 days at 4 ° C in Petri dishes on wet filter paper. According to the results, the stimulation of growth processes was identified under the GA effect in all investigated winter wheat varieties. The stimulation occurred as linear growth and biomass accumulation of seedlings, the intensity of which depended on the level of trophic support of these processes. The GA priming in the variant with the lack of trophic support did not significantly stimulate the content of carbohydrates in the varieties Doridna and Statna. It noticeably stimulated the content of carbohydrates in the Alians variety due to changes of oligosaccharides content. The patterns of phytohormonal and trophic regulation of vernalization processes in winter wheat are discussed.
