Influence of Salinity and Temperature on Germination of Trifolium repens

Abstract

In this study, germination character and growth of Trifolium repens were studied by using a completely randomized design with four replications at two levels of temperature regime (25°C and 35°C) and at five levels of salinity (distilled water, 3, 6 and 12 ds/m). The results of variance analysis showed that the different levels of salinity and temperature were highly significance on germination percentage, germination speed, length of root and length of shoot (p<0.01). Germination percentage showed that rate of germination decreased with an increase in salinity. Maximum germination speed, root length, and shoot length was related to 25°C temperature and control treatment and minimum of these character was belong to 5°C and 12ds/m salinity. In both of two levels of temperature treatment (25 and 35°C) differences between shoot length and root length was less by increasing in salinity levels.
