Application of GA3 (Gibberellic Acid) and Kinetin Plant Growth Agents in Relieving the Effects of Salt (NaCl) Stress on Germination and Seedling Growth of Common Vetch (Vicia sativa L.) Seeds

Abstract

In this study, the effects of different doses of GA3 and Kinetin plant growth agents were investigated in order to alleviate the inhibitory effect of salt (NaCl) stress on common germination and seedling growth of common vetch (Vicia sativa L.) seeds. The study was carried out in parallel with coincidence blocks in petri dish and pot. Different doses of NaCl (NaCl solution prepared in 0,5, 1,0, 1,5 and 2,0 dS doses) at different doses in the experiment. Kinetin and Gibberelic acid doses in different doses (Vicia sativa L.) seeds (Control-pure water, 300ppm Gibberellic acid, 50ppm Kinetin, 300ppm Gibberellik acid × 50ppm Kinetin) seed germinated in petri dish. The effects of germination percentage, average germination time, germination value, root and stem length, root age and dry weight, root age and dry weight on GA3 and Kinetin applications were observed. At the end of the research, GA3 and Kinetin applications did not have any effect on germination percentage, shorten germination time, increased germination value, GA3 application increased root and stem elongation Kinetin application had no positive effect, maximum root age and dry weight were obtained from GA3 and control units. The effects of GA3 and Kinetin applications on the properties examined in the study on common vetch seeds were very different. It was determined that GA3 applications increased root and stem length and kinetin application adversely affected
