  A highly reproducible in vitro shoot regeneration system in Aralia elata Seem. using root explants was developed in this investigation. Multiple shoots were induced in vitro directly from root explants through adventitious shoot bud regeneration. The ability of root explants to produce shoot buds depended on the supplementation of Plant Growth Regulators (PGRs). Maximum multiplication of shoots (18 shoots per explant) was achieved in a Broad-leaved Tree (BT) medium supplemented with 1.00 μM 6-benzyl aminopurine (BAP). The best and healthiest rooting was observed in a BT medium supplemented with 2.00 μM α-naphthaleneacetic acid (NAA). Regenerated plants were successfully acclimatized under ex vitro condition.

  Protocol for induction of callus and regeneration response of two sugarcane varieties (Isd-16, Isd-28) was established through callus culture using leaf sheath. Multiple shoot regeneration at various frequencies was observed using different concentrations and combinations of growth regulators. The highest percentage of callus induction was observed in the medium containing 3.0 mg l -1 2,4-D with 10% coconut water (CM). The best response in terms of multiple shoot formation was observed that on MS medium supplemented with BAP 1.0 mg l -1 +IBA 0.5 mg l -1. NAA (3.0 mg l -1) was found effective in the production of roots. The variety Isd-16 showed better response than the variety Isd-28 towards shoot multiplication. Seventy percent of the plantlets produced from in vitro culture method survived in the ex vitro condition.

  Shoot multiplication of Chrysanthemum morifolium was achieved from the nodal and shoot tip explants of mature plant using MS medium with different concentrations and combinations of growth regulators. Maximum frequency of explants produced axillary shoot and the highest number of shoots per explant were obtained when MS medium fortified with 1.0 mg l-1 BAP.The combination BAP+GA3 was found effective result. But Kinetin (Kn) showed low performance for producing multiple shoots. The degree of shoot formation was affected by explant types and the exogenous hormonal regime in the medium.

  Leaf segments from field grown mature plants of Elaeocarpus robustus Roxb. were used to initiate cultures for inducing callus and subsequent differentiation of shoot buds. Callus production was obtained within seven weeks and adventitious shoot formation was observed after five weeks of incubation on ½ MS medium supplemented with 0.5 mg l-1 BA + 0.1 mg l-1 NAA + 15% CW. Complete plantlets were obtained upon transfer of shoot cuttings on ½ MS with 0.1-2.0 mg l-1 IBA, NAA, IAA or without any auxin. The best and healthy rooting was observed on ½ MS medium supplemented 0.2 mg l-1 IBA. In vitro regenerated plantlets were transferred to potting soil and successfully established under natural condition with about 60% survival.

  Microshoots were cultured on MS medium supplemented with different combinations of auxin, sucrose and pH level for in vitro rooting of callus induced sugarcane (Saccharum officinarum) variety namely Isd 31. Among the types and concentrations of auxin used the best rooting in all the microshoots was obtained with half strength (major salts) MS basal medium supplemented with NAA at 5.0 mg l‾1, sucrose at 50 g l‾1 and pH level 5.7 were the optimum conditions for rooting when microshoots were incubated 25+ 2°C under 16 h photo period regime. The regenerated plantlets were successfully transferred to soil and the percentage of survivability under ex vitro conditions was 75.

  Leaf sheath were used as explants to induce callus on modified MS media supplemented with 2, 4-D as growth regulators. Different concentrations of BAP, IBA, NAA and IAA were used to regenerate shoots and a concentration of 1.0 mg/l BAP and 0.5mg/l IBA was found superior in the optimum production of multiple shoots. NAA (5mg/l) showed best performance in the production of roots. The plantlets were successfully transferred to soil with 70 percent survivability.

  An efficient protocol was developed for direct regeneration, multiplication and rooting under in vitro conditions of Chrysanthemum. The frequency of multiple shoot regeneration response was 95 and 91%, for nodal segments and shoot tips, respectively when cultured on the medium containing MS +1.0 mg l-1 BAP. Efficient rooting was achieved on half strength of MS+0.2 mg l-1 IBA. In vitro raised plantlets were transferred to potted soil and finally transferred to the field.
