چکیده

گل همیشه­ بهار گیاهی زینتی و دارویی است و دارای مصارف آرایشی و صنعتی نیز می ­باشد. به­ منظور بررسی اثر ورمی­ کمپوست و کود مایع جلبک دریایی بر خواص مورفوفیزیولوژیکی این گیاه، آزمایشی به­ صورت فاکتوریل بر پایه طرح کاملاً تصادفی با سه تکرار در شهرستان میانه انجام شد. در این آزمایش، فاکتور اول شامل کود ورمی­ کمپوست در چهار سطح (صفر، 5، 10 و ۱۵ تن در هکتار) به­ صورت افزودن به خاک گلدان و فاکتور دوم کود مایع جلبک دریایی در چهار سطح (صفر، 1، 2 و 3 درصد) به­ صورت محلول ­پاشی بر روی شاخ و برگ بودند. صفات مورد ارزیابی در این آزمایش شامل وزن خشک برگ،‌ ریشه و ساقه، حجم ریشه،‌ شاخص محتوای کلروفیل، تعداد شاخساره­ های فرعی، ارتفاع بوته، تعداد برگ، طول دوره گل­دهی، تعداد گل در هر بوته،‌ قطر گل، وزن خشک گل، درصد نشت الکترولیت از برگ، سطح برگ، درصد و عملکرد اسانس بودند. نتایج نشان داد که کاربرد ورمی­ کمپوست باعث افزایش در برخی صفات از جمله ارتفاع (18/58 سانتی­ متر)، تعداد شاخه فرعی (4/3 شاخه)، حجم ریشه (3/4 سانتی متر مکعب) و سطح برگ بوته (65/55 سانتی­ متر مربع) گردید. همچنین، در اکثر صفات مورد مطالعه، کاربرد ۳ درصد کود مایع جلبک دریایی مؤثر واقع شد. در کل، کاربرد معادل ۵ تن در هکتار ورمی­ کمپوست به همراه ۳ درصد کود جلبک دریایی برای اکثر صفات مانند وزن خشک گل و وزن خشک ساقه بهترین نتیجه را به دنبال داشت.

چکیده [English]

Marigold is an ornamental and medicinal plant and has also industrial in cosmetalogical uses. To evaluate the effects of vermicompost and seaweed fertilizers on some morpho-physiological properties of the plant, a factorial experiment based on a randomized complete block (RCB) design with three replications was conducted in pot in Mianeh. In this experiment, the first factor was vermicompost fertilizer at four levels (0, 5, 10 and 15 t.ha-1) added to the pot soil and the second factor was for levels of liquid seaweed fertilizer (0, 1, 2 and 3 percent) sprayed on foliage. The assessed traits were leaf, root and stem dry weights, root volume, number of secondary shoots, plant height, leaf number, flowering period, number of flowers, flower diameter, dry weight of flowers, leaves electrolyte leakage, leaf area (LA) and essential oil percentage and yield. The results showed that application of vermicompost increased some traits, including plant height (18.58 cm), number of branches (4.3 branches), root volume (3.4 cm³) and leaf area index (65.55 cm2). Using 3 percent of liquid seaweed fertilizer was also effective. In general, application of 5 tons per hectare of vermicompost with 3 percent of liquid seaweed fertilizer resulted in highest flower and stem dry weights.
