Abstract:
An experiment was conducted on the acclimatization of tissue culture banana plantlets cv. Grand Naine. The different potting media used for the present study were Coco peat, Sawdust, Sand, Red earth, and FYM. In which different propagation media of Cocopeat + Red earth + FYM (1:2:1), Sawdust + Red earth + FYM (1:2:1), Sand + Red earth + FYM (1:2:1) were used for hardening. Different Bio stimulants are used for VAM, KSB, Humic acid, Chitosan and 19:19:19. Which were used in different combinations to study the effect of hardening potting media bio stimulants on vegetative growth performances of banana under ex-vitro conditions. The in-vitro rooted plantlets were hardened and acclimatized by using different treatments. Plantlets were transplanted from hardening after 60 days of hardening gave maximum survival and growth under ex vitro conditions. The maximum survival and growth during hardening (100%) were observed in a shade net with maintained relative humidity and light intensity. Various potting media and bio stimulants were tried, containing (Cocopeat + Red earth + FYM and AMF + KSB) gave maximum growth and development including plant height (cm), pseudo stem girth (cm) leaf length, leaf width, leaf area and growth of tissue culture banana plantlets performances under ex vitro conditions.
