The comparison studies on the proliferation of lateral buds of Vitis vinifera L.cv. alphonse during different periods of the year at in vitro conditions

In this study, lateral buds of Vitis vinifera L.cv. Alphonse were used as material. During micropropagation, 2mg/l BAP (6-benzylaminopurine) and during rooting, 2mg/l NAA (?-Naftalen Aseticacid) was added into the Murashige-Skoog (1) medium, which is used in culture studies. our aim is to compare proliferation capabilities of lateral buds of Alphonse grapevine in terms of various periods of year in in-vitro conditions. As a result, rooty seedling were obtained from lateral buds cultivated in yearly period of time, and it was determined that the most favourable and productive seedlings were those obtained from materials cultivated in the months November and December. It was also established that the success rate of seedlings obtained from materials cultivated in these months was about 80-85%.
