Effect of different culture medium types and benzyl adenine concentrations on Cornelian Cherry (Cornus mas L.) shoots proliferation rate

Cornelian cherry (Cornus mas L.) is one of the Cornus species members belonging to Cornacea family. It is one of the native shrubs of the central and north-western parts of the Alborz Mountains in Iran. This study was conducted with the aim of establishment and proliferation of Cornelian cherry shoots with under invitro culture of lateral buds. For this purpose, two types of WPM and QL mediums and four levels of benzyl adenin (BA) (0, 0.5, 1 and 2 mg/L) with constant concentration of 0.5 mg/L of IAA for all replicates were used in a factorial experiment base on a completely randomized design with 5 replications. The highest proliferation indices, including number of shoots (4.79 for each sample), shoots length (1.41 cm) and number of nodes (32.5 for Each sample) was recorded at a concentration of 1 mg/L BA in QL medium. Also, the results of correlations between traits showed that all traits were positively and significantly correlated at p≤5% level. Considering the proliferation factors, the results showed a significant difference with the control group, and the positive and significant effect of benzyladenine and QL medium on the proliferation of cornelian cherry shoots is reported.
