The influence of leaf blade, nutrients, water and light on the promotion of axillary bud growth of isolated single-node stem segments of Paspalum distichum L.
Weed Research 31 (6), 385-394
Abstract: The presence of the leaf blade for 5 days or longer on isolated single-node stem segments of Paspalum distichum with an adequate supply of nutrients, water and light, produced better axillary bud growth than was observed on those segments without the leaf blade. Presence or absence of the leaf blade had no effect on segments in distilled water. Segments in Hoagland's solution of any strength exhibited significantly more growth than those in distilled water. In one-half or full-strength Hoagland's solution, segments generally showed significantly more growth than segments in lower strength solutions. Segments subjected to flooding, daily watering, submergence or hydroponic treatments exhibited significantly more growth than the segments that were watered every 3 days. Segments with the leaf blade retained, and those exposed to constant light, showed significantly better growth than segments without an attached leaf blade, or without light. It is concluded that the interactions between leaf blade, water, nutrients and light, which favoured photosynthesis and reduced transpiration, increased axillary bud growth. This interaction may provide a survival mechanism for isolated stems of P. distichum, assisting its rapid spread in wetlands.
