Effect of pre-sowing seed treatment on seed germination and vigour of aonla seedlings

摘要

The pre-sowing seed treatment with various concentrations of KNO. and GA was carried out to improve the germination percentage and vigour of the seedlings. The results revealed that maximum seed germination (93.33%), root length (31.33 cm) and root diameter (0.39 cm) were observed in the seeds treated with 1 % KNO, for 18 h. while lowest seed germination (53.33%), main root length (12.67 cm) and root diameter (0 22 cm) were recorded in control. The seedling height, number leaflets and survival of the100 days old seedlings were significantly more in 1% KNO, treatment.
