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

and GA

. 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

), 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.
