| چکیده | ||
| به‌منظور تعیین اثر تراکم بوته بر عملکرد و موسیلاژ دانه گیاه دارویی اسفرزه (Plantago ovata Forsk.)، آزمایشی در دو شرایط دیم، در دو ایستگاه تحقیقاتی مراوه‌تپه (کم‌باران) و چالکی‌گرگان (پرباران) انجام شد. این مطالعه در قالب بلوک‌های کامل تصادفی اجرا و به‌صورت تجزیه مرکب در مکان، تجزیه واریانس شد. کرت‌های آزمایشی با تراکم‌های 100، 200 و 400 بوته در مترمربع و با فاصله بین ردیف 20 سانتی‌متر کاشته شدند. نتایج تجزیه مرکب نشان داد اثر تراکم بوته بر طول سنبله، تعداد دانه در سنبله، وزن هزاردانه، درصد موسیلاژ و شاخص برداشت معنی‌دار نبود، در حالی‌که تعداد سنبله، عملکرد دانه و موسیلاژ در سطح 1% معنی‌دار شدند. تحت تأثیر مکان نیز تعداد سنبله در مترمربع، عملکرد دانه و موسیلاژ در هکتار در سطح 1% و شاخص برداشت در سطح 5% معنی‌دار شدند. اثر متقابل تراکم بوته و مکان بر عملکرد دانه و موسیلاژ در هکتار در سطح 1% معنی‌دار شد و سایر صفات اختلاف معنی‌داری نداشتند. عملکرد دانه و عملکرد موسیلاژ با افزایش تراکم از 100 بوته به 400 بوته در مترمربع در چالکی‌گرگان به‌ترتیب 3/2 و 9/2 برابر و در مراوه‌تپه به‌ترتیب 94/1 و 86/1 برابر افزایش یافتند. نتایج این تحقیق نشان داد که عملکرد دانه و موسیلاژ در هکتار در چالکی‌گرگان به‌ترتیب 71/1 و 69/1 برابر آن در مراوه‌تپه می‌باشد. براساس نتایج، همه صفات اندازه‌گیری شده در تراکم 400 بوته در مترمربع در چالکی‌گرگان، نسبت به تراکم‌های دیگر، در هر دو مکان برتری داشتند. | ||

| The effect of plant density on the seed yield and mucilage of Plantago ovata Forsk. was studied using a randomized complete block design under dry farming conditions at two stations: a) Maraveh-Tapeh , 240 km northeast of Gorgan, with a long-term average rainfall of 330 mm (low rainfall) and b) Chalaky station, 8 Km west of Gorgan with a long-term average rainfall of 550 mm (rainfed). The experimental plots were planted at densities of 100, 200 and 400 plants m-² with a distance of 20 cm between rows.Data were analyzed using a combined analysis. No significant differences were found for the effects of density on traits including seed number per spike, spike length, harvest index, 1000-seed weight and mucilage percentage, while there were significant differences for the spike number m-1, seed yield, and mucilage yield at 1% probability level. According to the results, the location effect was significant on spike number m-1, seed and mucilage yield (1% probability level), and harvest index (5% probability level). The interactions between plant density and location on spike number per square meter and seed and mucilage yield per hectare were significant at 1% probability level, while no significant differences were found for the other traits. The seed and mucilage yield increased with increasing plant density, so that the seed and mucilage yield at a density of 400 plants m-1 in the Chalaki station were 2.3 and 2.9 times and in the Maraveh-Tapeh station were 1.94 and 1.86 times more compared to 100 plants m-1, respectively. Seed and mucilage yield in Chalaky station were 1.71 and 1.69 times more compared to Maraveh-Tapeh station, respectively. Our results clearly showed superiority for all traits measured at a density of 400 plants m-1 in the Chalaky station as compared with other densities in both locations. | ||
