QUALITY IMPROVEMENT OF SOME VEGETABLE SEEDLINGS THROUGH SEED PRIMING WITH H2 O2 AND GA3

Abstract

This experiment was carried out at The Net House of Horticulture Farm of Sher-eBangla

Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka-1207 during the period from 1 st November to 30 th November 2018 to study the quality improvement of three vegetable seedlings viz. tomato, brinjal and chilli through seed priming with H 2 O 2 and GA 3 3 . Six priming treatments were applied under the present study viz. P

(no priming), P 1 (Hydro priming), P 2 (Priming with 0.5% aqueous solution of H ), P 3 (Priming with 1% aqueous solution of H (Priming with 100 ppm GA 3 2 O 2 ), P 4 (Priming with 50 ppm GA ). The experiment was laid out in Completely Randomized Design (CRD) with three replications. Data were collected on seed germination and growth parameters for each crop and analyzed statistically. Regarding seed priming performance on tomato (Part-1),P showed the highest percentage of seed germination (96.00%), shoot length (19.60 cm), root shoot ratio (0.38), RGR (0.30) and vigor index (3367.68)

whereas P 0 4 showed lowest performance for the respected parameters. The lowest abnormal seedlings of tomato were also found from P 4 treatment. In case of seed priming performance on brinjal (Part-2), P gave the highest percentage of seed germination (97.33%), shoot length (18.92 cm), RGR (0.30) and vigor index (3421.15) whereas P showed lowest results for the aforesaid parameters. The lowest abnormal seedlings of brinjal were also recorded from P 5 0 treatment. Consideration of seed priming performance on chilli (Part-3), P showed highest percentage of seed germination (88.00%), shoot length (17.88 cm), RGR (0.30) and vigor index (2921.60) whereas P showed lowest performance. The minimum abnormal seedlings were also recorded from P 0 5 treatment.
