In vitro regeneration
of banana
Shoot tip of BARI Banana-1
(Musa sp.) was cultured on MS
medium supplemented with 5.0
mg/l BAP for shoot proliferation.
Well developed shoots were used
for rooting. Among the six different
concentrations of IBA (0.1,0.2,0.3,0.4,0.5,0.6
mg/l) with half strength MS
medium, a good number of healthy
roots (7.86) were produced on
half MS + 0.5 mg/l IBA. 95-100
percent plantlets were survived
when they were transferred to
small plastic pots after 15
- 20 days in vitro culture and
7 days hardening at room temperature.

In vitro regeneration
of jackfruit
Shoot tip from matured tree
of jackfruit (Artocarpus heterophyllus
Lam) were cultured on MS medium
supplemented with different
concentrations of BAP. The highest
multiple shoot was observed
in 2.0 mg/l BAP. Rooting of
in vitro regenerated shoot was
made in half MS medium with
different concentrations of
IBA. Good rooting was obtained
in 2.0 mg/l IBA.

In vitro regeneration
of pineapple
The response of explant to various
combinations of auxin and cytokinin
in the MS medium were studied.
A combination of 1.76 mg/l NAA,
1.93 mg/l IBA and 2.0 mg/l Kn
was found optimum for establishment
of cultures and subsequent shoot
formation. The overall roots
and plant growth were also found
excellent in medium containing
0.2 mg/l NNA and 0.4 mg/l IBA.

Regeneration of teasle gourd
(Momordica dioica Roxb) through
tissue culture
Four types of explants of
teasle gourd viz. node, shoot
tip, leaf and the cotyledon
were used in this study. The
cotyledon showed best performance.
The combination of 1.0 mg/l
BAP and 0.1 mg/l/NAA were found
most suitable in callus induction.
The highest number of multiple
and tallest shoots were obtained
on MS medium supplemented with
1.0 mg/l BAP and 0.1 mg/l NAA.
Half strength MS medium supplement
with 0.3 mg/l IBA showed better
performance for root induction.

In vitro culture
of watermelon
In vitro grown shoot tips
and nodal segments from physiologically
mature seeds were cultured aseptically
on MS medium supplemented with
different concentrations of
cytokinin (BAP and Kn) and auxin
(IBA and NAA) for regeneration.
Shoot tips were found better
than nodal segments for shoot
induction. The highest number
of multiple shoots (15.4) and
longest shoot (5.2 cm) were
obtained on MS medium supplemented
with 0.2 mg/l BAP. The highest
number of roots/culture (7.5)
and the longest root (1.9 cm)
were produced in ½ MS
medium supplemented with 0.4
mg/l IBA.

In vitro regeneration
of chrysanthemum
Shoot tips of Chrysanthemum
morifolium ramat cv. 'super
yellow' and 'light violet' was
periodically subcultured on
IAA, NAA, Kn, BAP and coconut
water (CW) singly or in combinations.
Maximum explants regeneration
was observed in cv. super yellow
and light violet from MS media
supplemented with 0.8 mg/l Kn
+ 2.0 mg/l BAP + 0.5 mg/l IAA
+ 0.5 mg/l NAA + 10% CW and
0.8 mg/l Kn + 0.5 mg/l IAA +
10% CW combinations, respectively.
Cultivar light violet gave highest
number of multiple shoots per
culture on MS medium supplemented
with 5.0 mg/l BAP + 0.5 mg/l
NAA. The maximum number of root
was found in cv. super yellow
and light violet from the half
strength MS medium supplemented
with 0.2 mg/l IBA and 0.2 mg/l
IAA, respectively. The rooted
shoots were acclimatized and
successfully transferred to
plastic pots. After hardening,
they were transferred to the
main field and the survival
rate was observed 85%.

In vitro regeneration
of gladiolus
Flower stalk and cormel
tip explants were tested for
in vitro propagation of gladiolus.
The nodal segments of flower
stalk produced higher number
of shoots when cultured on MS
medium supplemented with 1.0
mg/l BAP. Shoot length was also
highest at the same concentration.
Regenerated shoots produced
roots and induced large cormlets
at the basal end when 2.0 mg/l
IBA and 60 g/l sucrose were
added to half MS medium. In
vitro cormlets germinated in
the field and produced flowers.

In vitro culture
of orchids
Seed of Dendrobium hybrid
orchid were cultured on MS medium
supplemented with different
concentrations and combinations
of growth regulators. Highest
percentage of seed germination
was observed in 2.0 mg/l NAA.
Highest shoot length, leaf number
and root length were observed
in 0.5 mg/l IAA + 1.0 mg/l IBA.

In vitro propagation
of rose
Node culture of hybrid tea
(Peace, Virgo, Inhar Canex),
climbers (Crimson Glory) and
miniature (Sunburst red) roses
were cultured on MS medium supplemented
with different concentrations
and combinations of BAP and
Kn. Kinetin was found less effective
than BAP for all cultivars.
However, the best response of
shoot multiplication was observed
at Sunburst Red with 1.5 mg/l
BAP. Crimson Glory, Inhar Canex
and Peace showed intermediate
response at 0.5 mg/l BAP with
0.2 mg/l Kn. Rooting occurred
within 5 weeks in all cultivars.
But the highest percentage of
rooting was obtained in Peace
(90%) at 0.5 mg/l IBA. The combination
of IAA (0.5 mg/l) and IBA (0.5
mg/l) showed intermediate result
(50%) for rooting in Crimson
Glory and Sunburst red.
