Abstract :

Nowadays heavy metal contamination in environment is becoming a big problem. The aim of this research was to study the effect of heavy metal copper on spore germination of Pteris vittata Linn. The concentrations of copper sulphate were 0 ppm, 5 ppm and 50 ppm. The characteristics of germinated spores were observed on an interval of 10 days and the study was continued till 30th day from the day of spore sowing. The result showed that the spore germination percentage and rhizoid mean number both increased gradually day by day in case of control set and 5 ppm set, though in 5 ppm set spore germination was delayed but in 50 ppm set, spore germination started very late as compared to the former two sets and the germinated spores were arrested in single celled stage, no further development occurred till 30th day. Key words: Pteris vittata Linn, copper sulphate, spore germination, protonema, spatulate, cordate.
