چکیده

embryogenic calli production in vitis is mainly possible by use of such regenerative tissues as anther and ovary. because of long periods of time required for obtaining such tissues, use of such vegetative organs as leaf explant would be a promising alternative. towards this end, leaf explants were taken from two varieties of ‘flame seedless’ and ‘red sultanina’ to be raised in. ms medium, consisting of 2.5 µm 2,4-d, 1.1 µm bap, 1 g/l cazein hydrolizate, 20 g/l sucrose, and 7 gr/l of agar. after two months, calli were transferred to the same medium except for 2-4, d which was replaced by naa. three months after explants' culture, calli were transferred to ms medium containg varied concentrations of bap (1, 2 & 3.5 mg/l), and iaa (2, 5 & 15 mg/l). results showed that among diffrent hormonal treatments, the fifth medium (bap 5 mg/l & iaa 2mg/l) induced a maximum embryogenesis in calli of cv. flame seedless.

تولید جنین‌های سوماتیکی در انگور بیشتر با کشت اندام‌های زایشی مانند بساک و تخمدان معمول است. با این حال استفاده از اندام‌هایی مانند برگ به عنوان ریزنمونه، به علت محدودیت زمانی جمع‌آوری اندام‌های زایشی در طی سال مورد توجه می‌باشد. در این آزمایش از دو رقم انگور بیدانه قرمز و فلیم سیدلس ریزنمونه برگ تهیه و در محیط پایه MS به همراه 2,4-D با غلظت 5/4 میکرومولار و BAP با غلظت 1/1 میکرومولار، 1 گرم در...
