Germination in Salt Stress of Sweet William (Dianthus barbatus L.) Seeds Applied Pretreatment of Gibberellic Acid

28904

This research was carried out to determine the effects of salt stress with pre applications in different doses of Gibberellic Acid (GA3) on germination of sweet william (Dianthus barbatus L.) seeds. Sweet william (Dianthus barbatus L.) was used as herbal material and the seeds were subjected to nine different applications. In the study, while the highest germination rate (83.50%) of sweet william seeds was found in watered with distilled water applied 40 ppm GA3 pretreatment, the lowest germination rate (4.00%) was determined on seeds pre-treated with distilled water and watered with 100 mM NaCl. The lowest mean germination time had been found in the seeds applied 20 ppm GA3 pretreatment and watered with distilled water with 3.10 (day). Salinity blocked the germination of sweet william seeds in depending on the concentrations. Pretreatment of GA3 plant growth regulators before germination, effect of inhibiting germination of salt stress had considerably diminished.
