Abstract

The study conducted to standardize the seed dormancy breaking treatment in senna (Cassia auriculata) revealed that soaking the seeds in hot water (boiled to 100°C and removed from the flame) for 15 min and soaking with 100 ppm GA3 for 3 h had effectively improved the germination (98%), root length (7.2 cm), shoot length (9.5 cm), dry matter production (0.258 g per ten seedlings) and vigour index (1637) compared to hot water treatment for 15 min alone (89% germination) and non-scarified seeds (20% germination). The seeds scarified with concentrated sulphuric acid also showed better germination than the non scarified seeds but less than the hot water scarified seeds.

Key words: Senna, Cassia auriculata, seed dormancy breaking, hot water treatment.
