Abstract
The present investigation was carried out in premises of Biotechnology cum Tissue Culture Centre, Odisha University of Agriculture and Technology, Bhubaneswar during 2015-16 and 2016-17. The objective of the study was to standardize suitable bio regulators on post harvest life of gerbera cut flowers. Apart from control, eight treatments of growth regulators like Gibberellins (GA3) @ 100ppm and 150ppm; cycocel @ 700 ppm and 800 ppm with and without amino acid were used as foliar spray. In winter season percentage gain weight of flower stalk (19.95%), percentage gain in flower diameter (4.95%), solution uptake (33.17 ml) and vase life (13.83 days) were maximum with application of cycocel @ 700 ppm + Amino Acid while percentage gain in stalk length (1.28%) of flower in vase was maximum in Gibberellin @ 150ppm + Amino Acid. Similar trends in change in above post harvest parameters were also observed in summer and rainy season.
