چکیده مقاله :

The impact of phenylphthalamic acid (PPA) rates including 0 (PPA0), 1000 (PPA1000), 2000 (PPA2000) or 3000 (PPA3000) mgL-1 and perfect fertilizer rates including 0 (PF0), 100 (PF100), 200 (PF200) and 300 (PF300) mgL-1 was studied on vegetative and reproductive growth of ornamental pepper plants. To realize this, a factorial experiment was conducted in a Completely Randomized Design with three replications. It was found that the interaction between ‘PPA × PF’ improved the measured traits; so that the shortest time to flower initiation (55.40 day), the shortest time to fruit set (62.93 day) and the highest fruit number (98.12 fruit) were related to the application of ‘PPA2000 × PF200’. Plants treated with ‘PPA2000 × PF300’ exhibited the most number of flowers (117.36), number of flowering stems (7.4), diameter of flowering stem (3.7 mm), plant height (45.83 cm), fruit fresh weight (6.71 g), fruit dry weight (3.79 g), plant fresh weight (21.96 g) and plant dry weight (15.17 g). Also, this treatment exhibited the highest fruit anthocyanin content and total chlorophyll. Conclusively, the application of ‘PPA2000×PF200’ is recommended because of the lower consumption of perfect fertilizer and the greater effect on traits having a beautiful and economic value for ornamental peppers.

چکیده انگلیسی:

به منظور بررسی اثر فنیل فتالامیک اسید (PPA) (0 (PPA0)، 1000 (PPA1000)، 2000 (PPA2000) و 3000 (PPA3000) میلی‌گرم در لیتر) و کود کامل (PF) (0 (PF0)، 100 (PF100)، 200 (PF200) و 300 (PF300) میلی‌گرم در لیتر) بر رشد رویشی و زایشی فلفل زینتی آزمایشی فاکتوریل در قالب طرح کاملا تصادفی در سه تکرار انجام شد. نتایج نشان داد که اثر متقابل "PPA×PF" موجب بهبود صفات مورد اندازه‌گیری می‌شود؛ بطوری‌که کمترین زمان تا آغاز گلدهی (40/55 روز)، کمترین زمان تا آغاز میوه‌دهی (93/62 روز)، بیشترین عمر گلدانی (93/93 روز) و بیشترین تعداد میوه (89/15) متعلق به تیمار "PPA2000 × PF200" بود. بیشترین تعداد گل (07/20)، تعداد ساقه گلدهنده (4/6)، قطر ساقه گلدهنده (7/3 میلی-متر)، ارتفاع بوته (83/45 سانتی‌متر)، بیشترین وزن تر میوه (71/6 گرم)، بیشترین وزن خشک میوه (79/3 گرم)، بیشترین وزن تر بوته (96/11 گرم) و بیشترین وزن خشک بوته (17/7 گرم) متعلق به تیمار "PPA2000×PF300" بود. همچنین این تیمار دارای بیشترین مقدار آنتوسیانین میوه (9/372 میلی‌گرم در 100 گرم وزن تر) بود. تیمارهای "PPA2000×PF300" و "PPA3000×PF300" نیز در صفات کلروفیل a، b و کل برترین تیمار بودند.
