Composted green waste as a container medium amendment for the production of ornamental plants.

摘要

Seed germination and crop growth characteristics were determined for Tagetes cv. Lemondrop, Catharanthus roseus cv. Little Pinkie, Petunia hybrida cv. Royalty Cherry, chrysanthemum cv. White Diamond, Pittosporum tobira cv. Wheeleri, Photinia Xfraseri and Juniperus sabina cv. Moon Glow grown in various size containers (pots and cellular trays) containing blends of composted green waste (CGW) and UC Mix. Seed germination, plant height, and stem and root fresh and dry mass were lowest in unamended CGW. For most plants studied, a CGW:UC Mix blend containing at least 25% UC Mix was required for adequate growth and development. Germinating seeds and young seedlings were most adversely affected by unamended CGW. As plants grew and were transplanted intolarger containers (10- and 15-cm pots), they were better able to grow in media with higher CGW content.
