Studies on vase life of different cultivars of tuberose (Polianthes tuberosa Linn)

Abstract

The present investigation entitled “Studies on vase life of different cultivars of tuberose (Polianthes tuberosa Linn)” was conducted during the period from September, 2016 to January, 2017 at the Department of Floriculture and Landscape Architecture, K.N.K. College of Horticulture, Mandsaur, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M.P.). The varietal difference had significant influence on the vase life parameters and biochemical parameters of tuberose in the present study. Among the varieties studied Suvasini recorded the maximum fresh weight (g) of cut spike during the all stages of observation (at harvest, on 3rd day and 5th day in vase and at senescence). Suvasini recorded the maximum moisture percent of cut spike both at harvest and at senescence. Suvasini recorded the maximum water uptake (ml) in vase during all the stages (on 3rd day and 5th day in vase and at senescence i.e., total water uptake) Suvasini recorded the maximum number of florets per spike, length of florets (cm) and diameter of florets (cm) Suvasini recorded the longest vase life (days) of cut spike Suvasini recorded the maximum sugar content (mgg fresh weight) in petals. Suvasini recorded the maximum peroxidase content (Units g tissue-1 min.-1) in petals.
