Abstract:
This experiment was conducted at Bihar Agricultural University, Sabour, and Bhagalpur in the Department of Horticulture (Fruit & Fruit Tech.) to show the effect of methyl jasmonate on physical, biochemical and yield behavior of strawberry cv. Nabila. Highest fruit length (4.70 cm) was recorded in treatment T3. There were no significant differences in fruit width, fruit weight, fruit volume were observed among the treatments of different doses of MeJA. The treatment of MeJA in regards to total soluble solids content in fruits was found significant with highest (11.77 ^oB) in 0.6 mM MeJA treated fruits. However, a non-significant difference in acidity of treated fruits was observed. The total sugar content of fruits had the highest (7.78%) and ascorbic acid content (78.65 mg/100g) under fruits treated with 0.6 mM MeJA. In case of phenolic content, the 0.9 mM MeJA treatment showed the highest (79.39 mg/100g). The effect of chemicals on the antioxidant and anthocyanin content of the fruits was found to be non-significant. Antioxidant content ranged between (25.94 µmol TE/g to 19.42 µmol TE/g). The anthocyanin content ranges from (32.35 mg/100g to 36.70 mg/100g). Maximum yield (18.33 fruits per plant) and was found in 0.6 mM MeJA treated plants.
