بررسی تأثیر غلظت‌های مختلف تنظیم‌کننده‌های رشد گیاهی بر ریزازدیادی گوجه‌فرنگی گیلاسی در شرایط in vitro

Cherry tomato, with small fruits, is one of the several varieties of tomato which is rich in vitamins such as C, A and K and antioxidant agents like lycopene. Therefore, it is very important from pharmaceutical and food perspectives. This research was carried out to optimize the best culture medium for micropropagation of this plant using single node culture technique under in vitro conditions. Results showed that the best treatment for micropropagation of cherry tomato plant, considering regeneration percentage, rooting percentage, shoot length, root length and number of internodes was basal MS medium supplemented with 1 mg/L Kin and 1 mg/L NAA, in which shoot length and number of internodes were highest among the treatments. All the plantlets that were transferred to the greenhouse survived and reached the fruiting stage. Maximum weight of fruits was obtained from explants grown in the MS medium (containing 1 mg/L Kin and 1 mg/L NAA).
