Abstract :
این آزمایش به منظور بررسی تاثیر کوکوپیت و پرلیت با سه نسبت (1:1 3:1 1:3 v/v ) در برخی از پارامترهای رویشی، گلدهی و بیوشیمیایی دو رقم گلادیول در شرایط بدون خاک در سال 2016 انجام شده است. داده ها حاکی از آن است که بیشتر پارامترهای رویشی عبارتند از: ارتفاع گیاه، تعداد برگ و سطح برگ، پارامتر گلدهی مانند ظهورشاخه، قطر شاخه، طول شاخه و تعداد گل گل در شاخه و پارامترهای بیوشیمیایی مانند کلروفیل a، کلروفیل b، قندهای محلول و جذب مغذی ( N، P و K ٪ در برگ ها) به طور معنی داری در ارقام، محیط کشت های و اثر متقابل آن ها تحت تاثیر قرار گرفت. نتایج نشان داد که بین اثرات متقابل ارقام و محیط کشت های در ارتفاع گیاه و وزن خشک گل که در رقم strong ومحیط کشت کوکوپیت و پرلیت با نسبت 1: 3 بالاتر از رقم white ومحیط کشت کوکوپیت و پرلیت با نسبت 3:1 به دست می آید . تمام پارامترهای مورد بررسی نشان دهنده افزایش قابل توجهی در محیط کشت کوکوپیت و پرلیت با نسبت 1: 3 در هر دو رقم بوده اند.
