چکیده

این پژوهش به‌منظور بررسی اثر تراکم‌های مختلف کاشت بر برخی خصوصیات مورفیزیولوژیک چمن ورزشی در شرایط تنش کم‌آبی انجام شد. آزمایش به‌صورت کرت‌های خرد شده، در قالب طرح بلوک‌های کامل تصادفی با سه تکرار اجرا شد. تیمارها شامل تنش کم‌آبی در سه سطح 90 (شاهد)، 60 و 30% ظرفیت زراعی و تراکم کاشت 20، 30 و g Seed/m2  40 بود. بذرها با توجه به تراکم‌های مورد نظر در کرت‌هایی به ابعادm2  3×2 کشت شدند. دو ماه پس از کاشت، تنش کم‌آبی به‌مدت 3 هفته اعمال شد. نتایج نشان داد که تیمار‌ها تأثیر معنی‌داری بر صفات مورد ارزیابی داشتند. بیش‌ترین وزن تر و خشک اندام هوایی، طول برگ و محتوای کلروفیل کل در تیمار 90% ظرفیت زراعی و تراکمg Seed/m2  20 مشاهده شد. در حالیکه بیش‌ترین وزن تر و خشک ریشه، حجم ریشه و کربوهیدرات کل در تیمار 30% ظرفیت زراعی و تراکمg Seed/m2  20 به‌دست آمد. همچنین بیش‌ترین میزان پرولین در تیمار 30% ظرفیت زراعی و تراکمg Seed/m2  40 بود. بنابراین با توجه به نتایج، تراکم کاشت g Seed/m2 20 و آبیاری در سطح 90% ظرفیت زراعی تأثیر مطلوب‌تری بر شاخص‌های رویشی و فیزیولوژیک چمن ورزشی داشت.

چکیده [English]

This research was conducted to investigate the effect of planting densities on some morphophysiological characteristics of sports turfgrass under low water stress conditions. The experiment was carried out in the form of split plots, based on a randomized complete block design with three replications. Treatments included low water stress at three levels of 90 (control), 60 and 30% of field capacity (FC), and planting density of 20, 30, and 40 g seed/m2. Seeds were planted according to the desired densities in plots measuring 2×3 m2. Two months after planting, low water stress was applied for three weeks. The results showed that the treatments had a significant effect on the evaluated traits. The highest fresh and dry weight of the aerial part, leaf length, and total chlorophyll content was observed in 90% FC and the density of 20 g seed/m2 treatment. The highest root fresh and dry weight, root volume, and total carbohydrates were obtained in 30% FC and density of 20 g seed/m2 treatment. Moreover, the highest proline content was in 30% FC and density of 40 g seed/m2 treatment. According to the results, the planting density of 20 g seed/m2 and 90% FC had a more favorable effect on the vegetative and physiological indicators of sport turfgrass.
