Abstract

AbstractCassava is propagated through vegetatively by stem cuttings. However, cassava sexual seeds are widely used by the breeders with the objective of developing new variety with its adaptibity in varying environmental conditions, disease resistance and high yield. But the limiting factors like hard seed coat, light, temperature and other intrinsic factors leads to poor   seed germination rate. The aim of this study was to enhance and obtain early seed germination in cassava, which takes 16 to 20 days under normal condition. The efficacy of different treatments like mechanical scarification, water treatment and Gibberellic acid was investigated. It was found that seed germination percentage was significantly varied among different treatments (p<0.01) and maximum seed germination at 7th day after treatment was observed for 50 ppm gibberellic acid treatment (T5), followed by 60ppm gibberellic acid for 30 minutes on cotyledons (T14). By comparing the results, 50ppm GA3, overnight soaked seeds (T5) had significant effect on germination (66.67 %) and can be used as a best treatment for getting early germination in cassava before 10 days.
