Abstract:
The present experiment was conducted to find out the “influence of plant growth
regulators and wounding to stem cutting of gardenia (Gardenia jasminoides) in
winter and summer season”, conducted at Horticulture farm, Sher-e-Bangla
Agricultural University, Dhaka. The experiment was laid out in Randomized
Complete Block Design (RCBD) with three replication comprising with one cultivar
(Gardenia Jasminoides) and the research work was conducted with one set of
treatment consisting of four growth regulator namely, T
vi
0
= Control, T
= Mixed plant
growth regulators (1000 ppm IBA + 1000 ppm NAA), T
= Wounding to cutting base
and T
3
2
= Wounding to cutting base + Mixed plant growth regulators. The effect of
these treatments on percentage of rooting, percentage of shooting, shoot no. and
length, root no. and length and survival percentage were studied. The results revealed
that the, growth regulators exerted significant influence on different parameters
studied. Among the growth regulators T
found superior in terms of significantly less
days taken for shooting and rooting of cuttings with maximum shooting and rooting
percentage. Similar trend were observed on the growth parameters such as number of
shoots and roots, length of shoot and root and survival percentage in both winter and
summer season. On the basis of the results obtained, it was concluded that the T
3
recorded the highest shooting, rooting and survival percentage of cutting and was
found most useful, healthy and vigorous planting materials of Gardenia Jasminoides.
