Abstract
An investigation was conducted at College of Horticulture, Mudigere during the year 2022-23 to study the effect of plant growth stimulants on seed germination of birdâs eye chilli. The statistical design adopted for seed germination study was Completely Randomized Design with fourteen treatments. Among the different treatments, the seeds treated with T4 (Thiourea @ 2 %) recorded significantly minimum days taken for germination (14.68) and maximum number of leaves (5.30). The seeds treated with T11 (GA3 @ 50 ppm) recorded significantly maximum germination percentage (91.65 %) and seedling vigour index (840.43). While, seeds treated with T12 (GA3 @ 100 ppm) recorded significantly maximum shoot length (5.26 cm), root length (5.18 cm), fresh weight of shoot (0.24 g), dry weight of shoot (0.032 g), number of primary roots (14.00), secondary roots (10.69) and seedling length (10.44 cm). The results revealed that soaking the seeds in GA3 @ 50 ppm would help improve seed germination in birdâs eye chilli.
