Abstract:

Study on “effect of plant growth regulators and chemicals on seed germination of avocado (Persea americana Mill.)” was carried out in college of Horticulture, Mudigere, during the year 2019-2020, under Complete Randomized Design with thirteen treatments and replicated thrice. Seeds were soaked in different solutions of plant growth regulators and chemicals. Among all treatments seeds soaked in GA3 400 ppm recorded early germination (13.00 days), 50 per cent germination (19.33 days), highest germination percentage (95.22), maximum shoot length (75.67 cm) and seedling vigour index-I and II (9878.54 and 806.60, respectively). Among all the treatments, GA3 400 ppm was superior to the other treatments, followed by GA3 600 ppm for the enhancement of germination traits.
