Flowering Control of Tuberose (Polianthes tuberosa L.) in Subtropical Conditions

Effects of temperature and the duration of corm storage on flowering and flower quality of tuberose were examined to establish the most practical method for controlled cut flower production in subtropical conditions. Low temperature storage did not increase cut flower production of the crop at all. Storage at 25C increased the loss of water content in the corms, but accelerated sprouting and flowering after planting and improved the quality of cut flowers when compared with low temperature treatments. It is advised that tuberose corms be stored at temperatures higher than 5C for late planting.
