Shoot tip culture of Bilecik İrikarası, Sarı Üzüm, Kartal Çavuş and Razakı grape varieties grown in Bilecik province

Abstract

The aim of this study was to determine the propagation potential of some local varieties using the in vitro shoot-tip culture method. Bilecik İrikarası, Sarı Üzüm, Kartal Çavuş and Razakı were used as materials. As a result of the study, the values of rooting rate, number of roots, length of roots, number of shoots, length of shoots, number of leaves and number of nodes of the grape varieties were determined. When the cultivars were compared in terms of rooting characteristics, the highest rooting rate was 54.7%, the highest root number was 3.71 per plant, and the highest average root length value was 17.93 cm from Bilecik İrikarası. When the cultivars were evaluated in terms of shoot length, the highest shoot length value was determined in Razaki variety with 5.72 cm. Similarly, considering the number of leaves and nodes in the shoots were determined, with the highest leaf number value was of 8.71, the highest node number value was of 6.71 in Razakı variety. As a result of the study, local varieties that used as material in this study showed positive results in in vitro propagation.
