Abstract
Seed germination is a vital event in the life cycle of a plant which determines its efficiency of survival. Irradiated carrageenan (ICR) is considered as gene regulator acting as signal molecules of the plant. Eucalyptus is one of the important essential oil-bearing plants and its oil is extremely valuable in medical and cosmetics applications. The study was aimed to find out the efficacy of best soaking concentration of ICR on the germination of Eucalyptus. The seeds were treated with aqueous solution of different concentrations viz. un-irradiated carrageenan (UCR) of 30 mg L-1 and four aqueous concentrations of ICR (irradiated at 250 KGy) viz. 30, 60, 90 and 120 mg L-1. Double distilled water (DDW) used as the control. The effect of ICR was found significant for the germination. Out of five tested concentrations of ICR, 60 mg L-1 proved optimum for the seed germination of Eucalyptus.
