Abstract

Asignificantreduction inseedgermination,seedlinggrowthanddryweightofAlbizia lebbeck, Peltophorum pterocarpum.
and Thespesia populnea was noted when zinc concentration was increased. A significant reduction (p<0.05) in seed
germinationduetozinctoxicityat50llg ml' wasobservedinA. lebbeck andP.pterocarpum. Higherpercentageofdecrease
in seed germination of P. pterocarpum was found with 1251lg ml' zinc treatment.The seedling length and seedling dry
weight ofA. lebbeck was significantly (p<0.05) reduced with 50llg ml' and751lg ml' treatment of zinc respectively.
