This study was conducted to screen out the cultivars of cut tuberose for longer vase
life on the basis of Membrane stability index (MSI). Five cultivars of tuberose
namely; Mexican Single, Phule Rajani, Prajwal, Shringar and Vaibhav were taken
for screening. Leakage of ions from the tuberose was measured over five arbitrarily
divided stages of the flower development in tuberose. Stage 1, tepals start reflexing
during bud opening; Stage 2, half bloom; Stage 3, full bloom; Stage 4, beginning of
wilting and Stage 5, complete wilting. There were declining trend in MSI value
irrespective of whether they are Single type or Double type cultivars. There was non
significant difference in membrane stability index during their first and second stage
of flowers development, but showed significant difference at later stages in flowers.
Cultivar Vaibhav had highest MSI value throughout the developmental stages of
flower as compare to other cultivars used in the experiment. It signified that leakage
of ions through membrane is significantly low. However, cultivar Mexican Single
showed comparatively lower value of MSI at Stage 5 which indicate that leakage of
ions through membrane is significantly high. There was non significant difference
between the cultivar Phule Rajani, Prajwal and Shringar.
