Uji Daya Simpan Biji Anggrek Dendrobium Stratiotes Rchb.f

Different storage times of Dendrobium stratiotes seeds were germinated to observe their longevity after the seeds were stored in a cold condition (freezer) under the temperature of -20 ºC. Four different media cultures were used to test the germination in in vitro culture. The result showed that the seeds of D. stratiotes were able to germinate in 4 different media i.e. Knudson C, modified Knudson C, modified Vacin & Went and modified Hyponex media, but the best medium was on modified Hyponex medium. The result showed that the viability seeds of Dendrobium stratiotes decreased within 3 months, and mostly no germination within 9 months. Storage seeds in low water content (10-13%) give higher result on the percentage of germination than on the higher water content (18-20%). The seeds of D. stratiotes should be sown soon after harvesting, and preserve them as seedling culture. Cryopreservation technique could be tried to extend the seed viability.
