Abstract Effects of temperature, light, salinity and depths of sowing on the germination of certain grass seeds (Lasiurus sindicus, Cenchrus ciliaris and C. setigerus) have been investigated. Seeds of C. ciliaris have the capacity to germinate under a wide range of temperatures but germination falls at temperatures above 45[degree]C. The other two grasses, however, show optimum germination around 32[degree]C. It was further observed that adverse effects of high temperature pretreatment are magnified with increasing duration of treatment and imbibed seeds are more affected than the dry seeds. Seeds of L. sindicus seemed to be less resistant to such pre-treatment, in comparison with the other two grasses. Under continuous light germination was reduced in all the three grasses and this inhibition was released when transferred to darkness. Tolerance to NaCl during germinative stage, also, varied considerably in these grasses. Seeds of C. setigerus showed maximum tolerance and least tolerance was observed in L. sindicus; C. ciliaris holds an intermediate position in this respect. Optimum depth of sowing for both large and small seeds of these grasses was found to be at 1.3 cm from the surface. || ABSTRACT AUTHORS: Authors
