Abstract:
Tuberose (Polianthes tuberosa L.) is a perennial, bulbous flowering plant, belongs to
family Amaryllidaceae. The study was conducted at postharvest research laboratory,
Department of CIHAB, Palli Siksha Bhavana, Visva-Bharti, Sriniketan, Bolpur during the
period of May 2014 to June 2014. Treatment details of experiment consists of T1= Control,
T2= Sucrose 2.5%, T3= Sucrose 5%, T4= Citric acid 2.5%, T5= Citric acid 5%, T6= AgNO3
15ppm, T7= AgNO3 30ppm, T8= Sucrose 2.5% + Citric acid 2.5%, T9= Sucrose 2.5% +
Citric acid 5%, T10= Sucrose 2.5% + AgNO3 15ppm and T11= Sucrose 5% + AgNO3
25ppm. Flowering spikes were kept in 200ml solution of 250ml conical flask and recorded
different post-harvest observations. Conical flask mouths were covered with a sheet of
polyethylene film. The experiment was laid out in Completely Randomized Design (CRD)
with three replications. Experimental results relieved that different vase preservatives
solutions were significantly affected the vase-life of tuberose flowers. The combination
and concentration of Sucrose 2.5% and AgNO3 15ppm were found to most suitable
preservative solution for extending the vase life of tuberose cut flowers.
