The present study deals with the callogenesis and micropropagation of grapes (Vitis vinifera L.) and biochemical investigation of protein content and peroxidase activity during different stages of growth. In the protocol of micropropagation, four different types of media with different concentration of auxin, cytokinin and their combinations were used. Best result was obtained with the TDZ 25.0 (uM) with 90% frequency rate. In the induction of callogenesis procedure, three different types of media concentration of auxin, cytokinin and their combination were used with leaf and node as explant....
