Penambahan Kulit Pisang dan Umbi Ubi Jalar pada Media Pertumbuhan Dua Varietas Krisan (Dendrathema grandiflora Tzvelve) secara In vitro

Abstract

This research aims to study the effect of addition various organic materials on the growth of chrysanthemum by in vitro. It was conducted at the Laboratory of Tissue Culture, Department of Agronomy and Horticulture. The experimental design was using a completely randomized design (CRD) with two factor. The first factor was media's treatment of organic material consists of seven standards (MS0 without the organic material, banana peels 50 g/l + ½ MS (½ concentration of macro, micro and vitamin), banana peels 100 g/l + ½ MS, banana peels 150 g/l + ½ MS, purple sweet potato 50 g/l + ½ MS, purple sweet potato 100 g/l + ½ MS and purple sweet potato 150 g/l + ½ MS). The second factor was the treatment of chrysanthemum varieties with two variety (Puspita Nusantara and Puspita Pelangi). The results showed that the addition of organic material in tissue culture media chrysanthemums influenced on plant height, number of leaves, number of roots, number of branches roots and root length. Chrysanthemum varieties influenced on plant height, number of leaves and number of branches roots. The interaction between organic media and chrysanthemum varieties occured in plant height at 4-10 weeks after cultured and root length of the longest at 10 weeks after cultured.
