Growth and flowering of tuberose as affected by adding natural zeolite to the culture medium

This research was conducted to investigate the effect of natural zeolite on vegetative growth and flower characteristics of tuberose (Polianthes tuberosa L.). The experiment was performed as a completely randomized design with seven treatments (5, 10, 15, 20, 25 and 30 g zeolite/kg soil mixture along with control) and four replicates. Results indicate that zeolite increased the height of flowering stem, diameter of flower, leaf area and chlorophyll content, but decreased the diameter of flowering stem, dry weight of shoots, and roots and bulblets. Overall, zeolite added to the soil mixture had beneficial effects on only some of the parameters of tuberose growth and development.
