Abstract:
Aonla (Emblica officinalis) is an important minor fruit crop of India. Demand for Aonla fruit is steadily expanding owing to its use in the cosmetic, pharmaceutical and processing industries. Aonla commercially propagated through patch budding but the availability of the quality seedling rootstock for budding technique is a major constraint in expanding area under aonla cultivation. Therefore, various physical treatments (hot water treatment and mechanical scarification using sand paper) and concentrations (200 ppm, 400 ppm and 600 ppm) of GA₃ were used for treating to aonla seeds in the experiment. The result indicated that mechanical scarification using sand paper is found to be the most effective for better seed germination (days taken to first germination, germination percentage and survival percentage) and seedling growth (length of seedling, total dry matter of seedling, Vigour Index I and Vigour Index II). Among GA₃ concentration, GA₃ @400 ppm recorded higher values for seed germination and seedling growth parameters of aonla. The treatment combination of scarification with sand paper + GA₃ @400 ppm showed better germination and seedling growth. Therefore, it is concluded that the combination of scarification with sand paper + GA₃ @400ppm was found most suitable for seed germination and seedling growth of aonla.
