RESPONSE OF POTHOS IN TEN GREENHOUSE MEDIA |
| Author: | A. Agut |
| Abstract:
Plant growth of Epipremnum aureum (pothos) was evaluated in ten greenhouse-container media. Materials commonly used to formulate these media by greenhouse growers were also evaluated for their nutrient, pH, soluble salt, cation exchange capacity and organic matter contents. Humus peats, although acidic, had relatively higher levels of nitrates, calcium, pH and soluble salts, and lower cation exchange capacity and organic matter content than peat moss. Plant growth was measured by four parameters:stem length, number of leaves, fresh weight and dry weight. Plant growth was greater in media containing peat moss than media containing humus peat. Soilless media produced more plant growth than media containing soils. Plant growth in media prepared by commercial greenhouse growers was comparable to media formulated with peat moss. Media containing humus peats were not as conductive to the growth of pothos as media containing peat moss. | |
