The orchids have contributed immensely to the international trade in floriculture due to their beautiful lustrous foliage and long lasting flowers of myriads shapes, sizes and colors. Though, the orchids represent one of the largest families of the flowering plants as state above, but orchid based floriculture has revolved around not more than 100 species in 10-12 genera. Presently, morphological and physiological changed have been documented in pollinated and un-pollinated flowers. The potential inhibitors namely TIBA (inhibitor of Auxins) and silver nitrate (Ethylene inhibitor) have also been used to enhance shelf life by delaying senescence related events. First visible change after pollination was observed in lip colour followed by wilting and swelling of ovary; start from 24 hrs following pollination. Shelf life of the flowers have been enhanced by 10-12 days using inhibitors of auxin and ethylene and ethylene found to be more pronounced effect in delaying senescence to enhance shelf life in taxa under investigations.
