چکیده

جهت بررسی مناسب‏ترین تاریخ کاشت، مکان کاشت و رقم گل شب‏بو برای عرضه در فصل بهار، آزمایشی به‏صورت کرت‏های دوبار خرد شده در قالب طرح بلوک‏های کامل تصادفی با سه تکرار در گلخانه تحقیقاتی دانشکده کشاورزی بردسیر، دانشگاه شهید باهنر کرمان در سال 1395 اجرا شد. تیمارهای آزمایش شامل تاریخ کاشت (15 شهریور، 15 مهر، 15 آبان، 15 آذر و 15 دی) به عنوان عامل اصلی، مکان کاشت (داخل و بیرون گلخانه) به عنوان عامل فرعی و رقم (دو رقم محلی قرمز و سفید و دو رقم اصلاح شده بنفش و صورتی) به عنوان عامل فرعی-فرعی بودند. نتایج تجزیه واریانس نشان داد که تأثیر تاریخ کاشت بر صفات ارتفاع بوته، تعداد روز تا غنچه‎دهی و گلدهی، قطر گلچه و گل‎آذین، تعداد گلچه در بوته، وزن تر گلچه و گیاه و دوام گل در سطح احتمال یک درصد معنی‎دار بود، ولی اثر معنی‎داری بر ارتفاع گل‎آذین نداشت. تأثیر مکان کاشت بر کلیه صفات به استثنای ارتفاع بوته و گل‎آذین و تعداد برگ در بوته معنی‎دار بود. نتایج نشان داد با تاخیر در کاشت، تعداد روز تا غنچه‎دهی و گلدهی در همه ارقام و در هر دو مکان کاشت کاهش یافت. دوره رشد ارقام محلی به‏طور معنی‎داری طولانی‏تر از ارقام اصلاح شده بود. کاشت در بیرون از گلخانه شرایط مطلوب‎تری نسبت به داخل گلخانه داشت. به‏طورکلی، کاشت رقم محلی قرمز در 15 مهر و در شرایط بیرون گلخانه مناسب‏ترین شرایط برای عرضه شب‎بو در اول بهار بود.

چکیده [English]

In order to study the most suitable planting date, planting site and variety of hoary stock for the supplying at spring season, an experiment was conducted as split-split-plot arranged based on randomized complete block design with three replications at experiment station of Shahid Bahonar University of Kerman in 2016-2017. Treatments were planting dates (5 September, 5 October, 5 November, 5 December, 5 January) assigned to main plot, planting sites (inside and outside of greenhouse) as subplot and variety (two red and white ecotypes and two violet and pink breeding varieties) as sub-subplot. The significant difference of planting date was detected in plant height, number of days to budding and flowering, floret and inflorescence diameter, number of florets per plant, fresh weight of floret and plant, and vase life of flowers but did not detect in inflorescence height. The planting site had significant effect on all the traits except plant height, inflorescence height, and leaf number per plant. The results showed that the delay in planting decreased number of days to budding and flowering in all the varieties and both planting sites. The growth period of local varieties was longer than the breeding varieties, significantly. Planting outside the greenhouse had more appropriate conditions than inside. In general, planting the local red variety at 5 October and out of greenhouse conditions was the most suitable treatment for supplying the hoary stock to the market on the first of spring.
