چکیده

امروزه کمبود عناصر ریزمغذی در تغذیه انسان سبب بروز مشکلات فراوان از جمله سو تغذیه می­ شود. یکی از برنامه‌های مهم متخصصان تغذیه افزایش میزان این عناصر در بخش‌های خوراکی گیاهان می‌باشد. به­ منظور تعیین تأثیر قارچ مایکوریزا و ریزمغذی‌ها بر صفات ریشه جو، تحقیقی در پاییز سال 1392 در شهرستان کرج به­ صورت آزمایش فاکتوریل در قالب طرح بلوک‌های کامل تصادفی با سه تکرار روی گیاه جو رقم بهمن اجرا شد. تیمارها شامل دو سطح قارچ، بدون مصرف، و خاک مصرف گونه intraradices Glomus به میزان 10 کیلوگرم در هکتار به صورت در کنار بذر، سه سطح آهن، بدون مصرف، مصرف 2.5 و 5 کیلوگرم در هکتار از منبع آهن سکوسترین 138 با بنیان Fe-EDDHA و سه سطح روی شاهد، مصرف 25 و 50 کیلوگرم در هکتار سولفات روی بودند. مقایسه میانگین ­های اثر ساده قارچ مایکوریزا روی صفت‌های طول کل ریشه، تراکم طول ریشه‌ها، طول مخصوص ریشه، درصد کلونیزاسیون ریشه و عملکرد دانه نشان داد که این صفات تحت تیمار قارچ به ­ترتیب به میزان 900.6 سانتی‌متر، 0.52 سانتی‌متر بر سانتی‌متر مکعب، 1738.1سانتی‌متر بر گرم، 5.41 درصد و 1 تن در هکتار افزایش نشان داده­ اند. مقایسه میانگین­ های اثر متقابل سه گانه قارچ مایکوریزا، روی و آهن نشان داد که تیمار مصرف قارچ مایکوریزا، 5 کیلوگرم آهن و عدم مصرف روی بالاترین میزان وزن خشک ریشه را به میزان 2.81 گرم دارا می باشد.

چکیده [English]

Deficiency of micro-nutrients in human diet may cause health problems. To increase the amount of these elements in the edible parts of the plants would eliminate the incidence of these health problems. Thus, the effects of iron and zinc on seed yield and morphological characteristics of mycorrhized barley (cv. Bahman) root was studied in Karaj, Iran, during growing season of 2013-14. It was carried out in afactorial experiment based on randomized complete block design with three replications. Treatments consisted two levels of mycorrhiza, non-inoculation (M0) and inoculation with 10 kg/ha of Glomus intraradices (M1), and three levels of iron from Fe-EDDHA (Sequestrene138) as control (F0), 2.5 kg/ha (F1) and 5kg/ha (F2) and three levels of zinc as zinc sulphate (ZnSO4) as control (Z0), 25 kg/ha (Z1) and 50 kg/ha (Z2). The results showed that application of mycorrhiza increased parameters like total root length (TRL), root length density (RLD), specific root length (SLR), root colonization percentage and grain yield by 900.6 cm, 0.52 cm/cm3, 1738.1 cm/g, 5.41% and 1ton/ha respectively. Mean comparisons also revealed that using iron, mycorrhiza and without Zn application increased levels of root dry weight (RDW) by 2.81 g.
