Studies to Evaluate Hydroponic Culture of Teak Seedlings in a Temperate Greenhouse

Teak (Tectona grandis L.f.) is one of the premier timber species globally. High demand, combined with harvesting restrictions across its natural range, has resulted in extensive plantation establishment. Plantations, in turn, depend on the production of healthy seedlings for successful establishment. As a lead up to assist growers in diagnosing seedling nutrient issues, we conducted a series of studies to test the feasibility of growing teak seedlings hydroponically in temperate greenhouses. Teak seedling studies were conducted in both sand and liquid culture hydroponic systems. Within each system, different strength nutrient solutions, solution pH levels, and pH buffers were tested to determine optimal conditions for growing seedlings. These studies indicated that teak seedlings could be successfully grown hydroponically in temperate greenhouses and responded best to a full-strength nutrient solution with a pH of 5.8 and a sodium hydroxide buffer. These results will be useful for conducting future studies to evaluate nutrient disorders in teak seedlings.
