Pertumbuhan Planlet Anggrek Cattleya sp. Setelah Penambahan Ekstrak Tomat (Solanum lycopersicum L.) pada Medium Vacin and Went

The purpose of this study was to determine the effective concentration of tomato extract (Solanum lycopersicum L.) for plant growth factors Cattleya sp. is percentage of number of small plants, plant height, number of leaves, number of buds and chlorophyll content. The study was conducted using a fully randomized design (CRD) consisting of 1 factor in the form of tomato extract using 5 levels of tomato extract concentration, namely 0%(as a control), 5%, 10%, 15%and 20%. The investigation was performed with 5 repetitions at each concentration and each repetition consisted of 2 stems of Cattleya sp. The results showed that the concentration of tomato extract in Vacin and Went medium was effective for the growth of Cattleya sp. namely a concentration of 15% (v / v) to increase the number of leaves and a concentration of 5% (v / v) to increase the number of shoots. The application of various concentrations of tomato extract on the plant height and chlorophyll content a, b and its amount gave a blocking effect.
