Grapevine is one of the oldest and most economically fruit crops. Grapes are a rich source of vitamins A, C, B6, as well as essential minerals, such as potassium, calcium, iron, phosphorus, magnesium and selenium. Crown gall disease (Agrobacterium vitis) is an economical disease in most vine yards. Since the bacterium remains in soil for a long time control of Agrobacterium is very difficult. Use of resistant rootstocks is the most effective methods for control of soil-borne pathogens, especially this bacterium. In this study, the reaction of the eight grape varieties (Shahani, Askari, Rish baba, Sefid-e-yaghuti, Qazvin Sefid-e-Keshmeshi, Qazvin Ghermez-e-Keshmeshi, Mehre and Rotabi) to crown gall was studied. In the first experiment, the rooted cuttings of different varieties inoculated in four sections with 20 ml of 108 cfu A. vitis and distillated water were compa.. View more»
