ABSTRACTS An experimental study was conducted to find out the effect of Blue light on Salvinia molesta. It was found that blue light enhances the vegetative growth under laboratory conditions. Another experiment was performed to find out the effect of acoustical waves on the growth of Pterisvittata. It has been observed during experiment that this fern grows even in the area where exhaust fumes are emitted by generators. This fern was subjected to wave frequencies of 1000, 500, 420, 380 & 100 Hz under a photoperiod of 14/10 h (day/night). Maximum growth was recorded to be dependent on the medium composition and independent of sound application. Sound waves applied during the dark period had no significant effect.
