Stamens are six in number, ovary 3 locular, ovules numerous and fruits are capsule. 4. 1 Introduction. Tuberose although not strictly photosensitive, long-day exposure promotes vegetative growth as well as early emergence of the first flower spike and also increases the length of flower spike. Concrete content has been observed to be 0.08 to 0.11 per cent. To hasten curing, artificial heat of 27o to 35o C may be applied. leaves get detached from the plant. •The disease symptoms are preceded by the appearance of prominent spots of loose green colour due to rotting which extend and cover the entire leaf.
