Media containing Weblite were compared to various media for its effectiveness in germination, plant growth and rooting. The 2M media were compared by determining the percentage germination and the dry weight after U2 days of Lycopersicon esculentum cv Better Boy, grown to transplant size. These media were composed of various proportions and combinations of Weblite, vermiculite, Jiffy Mix, peat moss and sand. The available moisture, porosity,field capacity and permanent wilting point of these 2b media were determined. This information was compared with the results from the germination and growth study of tomato plants. Weblite was a constituent of the seven best media for germination. Tomato plants grown in media containing vermiculite had the highest dry weights. Chrysanthemum morifolium cv Sunny Mandalay stem cuttings were rooted in six media. These media were composed of various proportions and combinations of sand, peat moss, Weblite, and perlite. Their root system and foliage condition were evaluated 18 days later. Weblite was significantly better in rooting Chrysanthemums than the six other media.Dianthus caroyphyllus cv Caribe stem cuttings were rooted in nine media. These media were composed of various proportions and combinations of sand, peat moss, Weblite. perlite, and vermiculite. Their roots, stem and foliage condition were evaluated 26 days later. The best root system developed in media with vermiculite as its main constituent. / Master of Science
