چکیده مقاله :

In order to evaluate the effect of medium and spraying calcium nano-fertilizer on quality of cut gerbera flowers, an experiment was conducted as factorial in completely randomized design with 7 media and 3 calcium nano-fertilizer concentrations with 3 replications. The media included cocopeat + perlite (1:1), peat moss + perlite (1:1), mushroom compost + perlite (1:1), peat moss + cocopeat + perlite (1:1:2), mushroom compost + peat moss + perlite (1:1:2), mushroom compost + cocopeat + perlite (1:1:2) and mushroom compost alone. The concentrations of calcium nano-fertilizer were 0, 1 and 2 mgL-1. Results demonstrated that different media had significant influence on flower diameter, neck flower diameter and vase life. The highest diameter of flower and neck flower were observed in peat + perlite (1:1), the highest flower fresh weight in cocopeat + mushroom compost + perlite (1:1:2) and the greatest vase life in peat + cocopeat + perlite (1:1:2) media. Calcium nano-fertilizer had a significant effect on vase life and flower quality, so that vase life was increased by enhancing the concentration of calcium nano-fertilizer. In interactions between medium and nano-calcium fertilizer, the highest flower number was observed in peat + mushroom compost + perlite (1:1:2) medium without nano-calcium fertilizer, and the greatest anthocyanin was related to peat + cocopeat + perlite (1:1:2) medium without nano-calcium fertilizer. There was no significant interaction in other traits.

چکیده انگلیسی:

به منظور بررسی تأثیر محیط کشت و محلول‌پاشی نانو کود کلسیم بر کیفیت گل شاخه بریده ژربرا، آزمایشی به صورت فاکتوریل در قالب طرح کاملاً تصادفی با 7 تیمار بستر و سه تیمار نانو کود کلسیم در سه تکرار انجام شد. محیط های کشت عبارت بودند از: کوکوپیت + پرلایت (1:1)، پیت­ماس + پرلایت (1:1)، کمپوست مصرف شده قارچ + پرلایت (1:1)، پیت­ماس + کوکوپیت + پرلایت (1:1:2)، کمپوست مصرف شده قارچ + پیت­ماس + پرلایت (1:1:2)، کمپوست مصرف شده قارچ + کوکوپیت + پرلایت (1:1:2) و کمپوست مصرف شده قارچ به تنهایی. غلظت های نانوکود کلسیم صفر، 1 و 2 میلی گرم در لیتر بود. نتایج نشان داد تیمارهای مختلف بستر اثر معنی‌داری بر روی قطر گل، قطر گردن گل و عمر گلجای داشت. بیشترین قطر گل و قطر گردن گل در بستر پیت + پرلیت (1:1)، بیشترین وزن تر گل در بستر کوکوپیت + کمپوست مصرف شده قارچ + پرلیت (2:1:1) و بیشترین عمر گلجایی در بسترهای پیت­ماس + کوکوپیت + پرلیت (2:1:1) مشاهده شد. تیمار نانو کود کلسیم بر عمر گلجایی و کیفیت گل اثر معنی‌داری داشت، به­طوری که با افزایش غلظت نانو کود کلسیم، عمر گلجایی افزایش یافت. در مورد اثرمتقابل بستر و نانو کود کلسیم، بیشترین تعداد گل در محیط کشت پیت­ماس + کمپوست قارچ + پرلیت (2:1:1) بدون نانوکود کلسیم و بیشترین آنتوسیانین در بستر پیت + کوکوپیت + پرلیت (2:1:1) بدون نانوکود کلسیم مشاهده شد. در بقیه صفات اثرمتقابل معنی داری بین دو فاکتور مشاهده نشد.
