Munıre Nıhan Bagdatli, Bengı Baba Erdağ
In this study, spore germination features and protonema development of Grimmia dissimulata, Syntrichia ruralis, Syntrichia laevipila and Syntrichia princeps were investigated under in vitro culture conditions for the first time. All of these species are positively photoblastic with exosporous germination. Spore swelling and germination was observed in the Distilled Water medium supplemented with 1.5 % (w/v) sucrose (Grimmia dissimulata, Syntrichia ruralis, Syntrichia laevipila and Syntrichia princeps with germination percentages 94%, 34%, 54% and 43% respectively) and half strenght Murashige and Skoog medium without sucrose (for only Grimmia dissimulata; germination percentage was 51%). The sporeling types were identified as “Bryum type” for G. dissimulata and S. laevipila and “Encalypta type” for S. ruralis and S. princeps.
