Effect of temperature on seed germination of bird of paradise (Strelitzia reginae)

Abstract

The first experiment consisted of exposing seeds to five different temperatures i.e., 20 ºC/30 ºC -16/8 hrs., Constant 30 ºC for 24 hrs., constant 35 ºC for 24 hrs., 25 ºC/35 ºC for 16/8 hrs. and control (room temperature-25±2 ºC) in Complete Randomized Design with four replications. Significant differences were observed among the treatments for mean germination percentage, days taken for initiation of germination, days taken for fifty percent germination, days taken for seventy percent germination and on growth parameters. The mean germination percentage and growth parameters were found to be maximum in the temperature 20 ºC /30 ºC -16/8hrs.
