Abstract
The present investigation entitled, “Effect of Storage Temperature, Storage Containers and Storage Duration on Seed Viability of Stevia rebaudiana” was carried out in laboratory and experimental area, located at Nauni of the Department of Forest Products. The experiment comprised of treatments: (A) Storage conditions: 1) At room temperature, (2) In refrigerator (4⁰C – 6⁰C): B) Storage containers: (1) Plastic bags, (2) Paper bags, (3) Cloth bags; C) Storage duration: (1) 0 month (immediate after harvest) ( control), (2) Up to 1 month, (3) Up to 2 months, (4) Up to 3 months, (5) Up to 4 months, (6) Up to 5 months, (7) Up to 6 months with 3 replications in Completely Randomized Design. The results showed that the seed viability was found to decrease with the increase in storage duration irrespective of storage container and storage temperature. Seed viability was found to decrease from 83.33% (freshly harvested seed) to 52.78 % (under refrigerated condition) and 40% (under open storage) after 6 months of storage. Among different storage containers, plastic bags retain maximum viability (53.33%) and cloth bags recorded minimum (40.00%) after 6 month of storage. However, mean viability of seeds decreased to 46.39 % after 6 month of storage. Hence plastic bags under refrigerated conditions proved to be the best containers for retaining maximum seed viability of Stevia rebaudiana.
