Effects of different media vitamins and various concentrations of 6-Benzylaminopurine on in vitro proliferation of Rosa canina

Dog rose (Rosa canina L.) is a medicinal plant. The fruits of this plant have many medicinal properties that are unknown to many people, especially in Iran. In vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and production of healthy and disease-free plants. Vitamins of media and plant growth regulators are one of the most important factors in the plant micropropagation. The aim of this study was to investigate the effects of various concentrations of 6- Benzylaminopurine (BAP) and vitamins of media (MS and LS) on the proliferation of nodal segments of Rosa canina. This experiment was performed as completely randomized design (CRD) with factorial arrangement. The results of this study showed that the highest percentage of proliferation (90%) and number of shoots (4.7) were observed in 0.5 mg/l BAP in MS medium vitamins. While the highest number of nodes (4.24) was obtained in 1 mg/l BAP in MS medium vitamins. As a general conclusion, the results of this study showed that MS medium vitamins have a better effect on proliferation of nodal segments of Rosa canina than LS medium vitamins.
