Abiyotik stres koşullarında yetiştirilen Gypsophila pilulifera (Caryophyllaceae) tohumlarının in vitro çimlenme ve vejetatif büyüme özellikleri

Gypsophila pilulifera Boiss. & Heldr. is an economically important critically endangered (CR) endemic species of Turkey. This a Mediterranean element and type sample located in square C3 (Antalya). Plants are much more sensitive to abiotic stress factors, especially during germination seedling development stages. In this study, vitro growth properties G. (Caryophyllaceae) were investigated under salt drought stress. The seeds cultured hormone-free MS media containing increasing doses NaCl (50, 100, 150, 200 mM) PEG 6000 (5%, 10%, 15% 20%). Germinated counted every three days for the first week day second week. root hypocotyl length, number leaves, fresh weight vigor index plants determined at end 21 days. A negative correlation was between increased all vegetative parameters. Although obtained on medium with highest level (20%), there no mM NaCl. As result, it that plant salinity than high concentrations inhibited by 100%.
