Abstract :

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.
