Salinity, chitin and GA 3 effects on seed germination of chervil (Anthriscus cerefolium)

Abstract

Abstract The seed germination observation of chervil (Anthriscus cerefolium) lasted 35 days at a temperature of 20 ο C. The effect of sodium chloride (NaCl), chitin and gibberillic acid (GA 3 ) on seed germination of chervil was studied for 35 days at a temperature of 22 ο C under controlled growth chamber conditions. For this, various aqueous solutions of NaCl (80, 120, 180, 240 mM NaCl), chitin (1, 2, 3, 4% ) and GA 3 (100, 200, 500, 1000 ppm GA 3 ) were used as germination substrates. The above solutions used solely or combined and added on Petri dishes containing fifty chervil seeds. The seed germination of chervil in the control (H 2 O) was 44%. In the 80 mM NaCl concentration there was an increase in the germination (64%) while in higher NaCl concentrations the germination reduced. The seed germination percentage of the chervil in the substrates with 1% and 2% chitin as the 200, 500 and 1000 ppm GA 3 was increased than the corresponding one in H 2 O. With increasing rate of chitin and GA3 the seed germination of the chervil was reduced. In the combinations of 80 mM NaCl+ 1% Chitin, 120 NaCl + 1% chitin, 120 NaCl + 100 GA 3 , 180 NaCl + 2% chitin and 180 NaCl + 200 GA 3 germination increased and the Timson Index of germination velocity was higher than the corresponding velocity in H 2 O
