EFFECT OF TEMPERATURE, MEDIA AND LIGHT ONGERMINATION OF PRINSEPIA UTILIS ROYLE SEEDSPrabal Kumar, Kalpana Tyagi, Manish Singh and Devendra Kumar
Effect of temperature and media was studied on seed germination of Prinsepia utilis Royle (bhekal).Germination tests were conducted at four different temperatures viz. 5Â±1 oC, 15Â±1 oC, 25Â±1 oC and ambientroom temperature with three germination media viz. top of germination paper (TP), between of paper (BP)and quartz sterilized sand at 90Â±5% relative humidity in a seed germinator for 21 days. Media andTemperature significantly affected seed traits. Seeds germinated well over wide range of temperature 15Â±1oC, to ambient room. Significantly, higher germination percentage, germination value (GV) and minimummean germination time (MGT) were obtained at 25Â±1 oC. lower than 25Â±1 oC and higher temperature (ambientroom temperature) had adverse effect on germination of bhekal seeds. Among media, between paper (BP)was found the best in which maximum germination percentage, minimum MGT and maximum GV wasrecorded. Sand media was found inferior as compared to between and top of paper. Seed germination wasunaffected with light.
