Abstract

The effect of different temperatures and different germination media in J. curcas seeds was studied in the present work. The influence of 8 constant temperatures viz. 20°C, 22°C, 25°C, 27°C, 30°C, 32°C, 35°C and 37°C, 4 alternate temperatures viz. 37/27°C, 35/25°C, 32/22°C and 30/20°C and 6 germination media viz. vermiculite, coco-peat, perlite, normal soil, sand and filter paper were used for the observation. The optimum temperature for the germination of J. curcas seeds was recorded “30°C” and suitable germination media was recorded “Vermiculite” for the reason that the highest germination percentage 84.44 recorded at 30°C whereas in Vermiculite has recorded 85. Key worlds: J. curcas, seed germination, different temperatures and different germination media.
