Abstract

The aim of the present study was to enhance the germination rate of Andrographis paniculata seeds which have a very low germination rate under normal conditions. The seeds were soaked in different hormonal solutions i.e. GA (10ppm), IAA (10ppm), IBA (10ppm), Kinetin (10ppm), GA+ Kintetin (10 ppm), IAA+ Kintetin (10ppm) and IBA + Kintetin (10 ppm), and 50 o C hot water at three treatment times (5,10 and 15 min) before placing in Petri plates. The seeds of A. paniculata treated in hot water for 5 min showed maximum germination percentage of 93%. Analysis of variance indicated that both hormonal and hot water treatments had a significant effect on seed germination and final germination percentage. The results showed that hormonal treatments are not useful methods for breaking the seeds dormancy.
