EFFECT OF SEED PRIMING ON GERMINATION, GROWTH AND FLOWERING OF SNAPDRAGON (ANTIRRHINUM MAJUS)Kirandeep Kaur and Jujhar SinghAbstract The present investigation entitled âEffect of seed priming on germination, growth and flowering of snapdragon var. Snapshot burgundyâ was carried out during 2022-23. The experiment was laid out in randomized block design with seven treatments and three replications. The treatments were non-primed seeds, Distilled water, GA3 150 ppm, GA3 250 ppm, KNO3 0.02M, KNO3 0.002M and Trichoderma viride. Observations were recorded for germination, vegetative and flowering parameters. Among all the treatments maximum germination percentage (65.33%) and early germination (5.00 days) was recorded in GA3 (150 ppm). Vegetative growth parameters such as plant height and branches per plant were found best in KNO3 (0.002M). Maximum number of spikes per plant (22.25 spikes) and maximum spike length (24.87 cm) were also found in KNO3 (0.002M). Therefore, GA3 and KNO3 in low concentration can be recommended for seed priming of Snapdragon. |
