Abstract: 

Three species of Graci/aria such as G.edulis, G. crassa and G. corticata were exposed to different broad band of lights. Red (> 600 nm), green (450-610 nm) and blue (390·570 nm) lights were provided to the plants kept in different growth chambers maintained with constant temperature of 28°C and photoperiod of 16:8 h light and dark period. The plants maintained under WL were considered as controL Photosynthetic activity and chlorophyll content were found to increase in all the species during 6th day of observation. Plants maintained GL exhibit higher cOIwentration of chlorophyll in G.edulis and G. corticata.
