Effect of harvesting time of flowers on concrete and absolute recovery in tuberose (Polianthes tuberosa L.): A comparative study of single and double Petalled cultivars

Abstract

The present investigation was carried out to study the effect of harvesting time of flowers on concrete and absolute recovery in single and double petalled tuberose (Polianthes tuberosa Linn.) genotypes. It has been found that flowers of Single petalled cultivars gave maximum concrete and absolute as compared to the double petalled type of flower. The flower harvested in the morning gave better results as compared to the flower harvested in the evening. In single type of flowers, maximum concrete and absolute recovery (0.161 - 0.047%), and (0.153 - 0.037%) was recorded in cultivar Prajawal when flowers harvested in the morning and evening respectively. However, in double petalled cultivars, the maximum concrete and absolute recovery (0.076 - 0.015%), and (0.066 - 0.012%) was obtained from the cultivar Suvasini when flowers were harvested in the morning and evening respectively. The results indicated that the flowers were harvested in the morning to get for better recovery of concrete and absolute in tuberose.
