چکیده | ||
در این پژوهش، بهمنظور بهبود صفات کمی و کیفی انگور بیدانة ’یاقوتی‘، محلولپاشی اسید جیبرلیک در چهار غلظت صفر (شاهد)، 15، 25 و 40 میلیگرم در لیتر در سه مرحله و عملیات حلقهبرداری همزمان با محلولپاشی مرحلۀ سوم در قاعدۀ شاخههای بارور بوتهها در چهار تکرار انجام گرفت. تیمار اسید جیبرلیک بهطور معناداری موجب افزایش طول خوشه در مقایسه با شاهد شد، بهطوری که طول محور خوشه، 14 روز پس از محلولپاشی در نمونۀ شاهد در حدود 46/13 سانتیمتر بود، ولی در غلظتهای 15، 25 و 40 میلیگرم در لیتر اسید جیبرلیک بهترتیب 87/17، 73/19 و 95/23 سانتیمتر بهدست آمد. محلولپاشی اسید جیبرلیک و حلقهبرداری سبب افزایش وزن حبه و خوشه شد، بهطوری که حداکثر وزن حبه (42/1 گرم) و خوشه (7/483 گرم) در برهمکنش بین غلظت 40 میلیگرم اسید جیبرلیک و حلقهبرداری بهدست آمد. همچنین عمل حلقهبرداری در مقایسه با شاهد بهطور معناداری به افزایش طول و عرض حبه منجر شد، اما در برخی از شاخصهای مورد بررسی معنادار نبود. کاربرد اسید جیبرلیک و عملیات حلقهبرداری سبب افزایش نسبت قند به اسید شد و تفاوت معناداری با نمونۀ شاهد داشت. | ||

چکیده [English] | ||
In the current study, for improving quality and quantity of ‘Yaghooti’ seedless grape, gibberellic acid was sprayed in four concentrations including zero (as control), 15, 25 and 40 mg/l, at three stages, and girdling treatments were carried out simultaneously with the third step of GA3 spraying at the base of fruit bearing shoots with four replications. The cluster length was significantly increased by all three concentrations of GA3 in compare with the control. In fact, 14 days after GA3 spray, the cluster length respectively grew to 17.87, 19.73 and 23.95 cm at 15, 25 and 40 mg/L GA3, whereas, in the control sample it was 13.46 cm. Furthermore, the berry and cluster weight were increased by foliar application of GA3 and girdling in which the maximum berry weight (1.42 gr) and cluster weight (483.7 gr) were achieved by interaction of 40 mg/l GA3 and girdling. In addition, girdling treatment significantly led to the increase of the berry length and width as compared to control sample; however, for some traits there was not any meaningful treatment. Application of GA3 and girdling treatment significantly led to the increase of the TSS/TA ratio in compared to control. | ||
