چکیده

آثار مفید و مثبت همزیستی میکوریزائی بر رشد گیاهان مختلف در گذشته اثبات شده است. این قارچ­ها با ایجاد رابطه همزیستی با ریشه اغلب گیاهان منجر به بهبود ویژگی­های مورفولوژیک و فیزیولوژیک گیاهان و حفظ تعادل در تنوع زیستی خاک می­شوند. اغلب گیاهان زراعی قادر به برقراری همزیستی با قارچ­های اندومیکوریزا هستند ولی تاکنون مطالعه­ای در مورد امکان برقراری ارتباط همزیستی این قارچ­ها با گل سوسن انجام نشده است. به­همین منظور تحقیقی جهت بررسی تأثیر گونه­های مختلف قارچ میکوریزا شامل Glomus intraradices، Glomus etunicatum،  Glomus mosseaeو Glomus clorum بر عملکرد دو گونه سوسن چلچراغ و سوسن شرقی انجام گردید. این تحقیق به صورت فاکتوریل در قالب طرح کاملاً تصادفی و در سه تکرار انجام گرفت. نتایج نشان داد که ریشه سوسن چلچراغ و سوسن شرقی با قارچ مذکور در حد قابل قبولی همزیستی ایجاد نموده است و اثر متقابل میکوریزا بر دو گونه سوسن از نظر صفات مورد بررسی معنی­دار می­باشد. بالاترین درصد کلونیزاسیون ریشه در سوسن شرقی در تیمار تلقیح با قارچ G. etunicatum مشاهده شد در حالی­که کمترین درصد کلونیزاسیون ریشه در سوسن چلچراغ تلقیح شده با قارچG. clorum  و سوسن چلچراغ شاهد مشاهده شد. همچنین بالاترین ارتفاع بوته در سوسن شرقی تلقیح با قارچ G. etunicatum و کمترین ارتفاع آن در سوسن چلچراغ شاهد مشاهده گردید. اثر متقابل سوسن و میکوریزا نشان داد که بالاترین میزان جذب فسفر، آهن و روی در سوسن چلچراغ و سوسن شرقی تلقیح شده با قارچ G. etunicatum مشاهده شد. در واقع نتایج این تحقیق حاکی از تأثیرگذاری همزیستی قارچ G. etunicatum بر رشد و میزان جذب عناصر می­باشد که زمینه را برای بررسی امکان کاربرد آن در بهبود رشد گیاه سوسن چلچراغ فراهم می­سازد.

چکیده [English]

Positive and beneficial effects of mycorrhizal symbiosis on growth of different plants have been demonstrated in the past. These fungi by creating a symbiotic relationship with the roots of plants leads to improved morphological and physiological characteristics and are balancing on soil biodiversity. Most of the crops are capable of establishing symbiosis with endo-mycorrhizal fungi, but so far, no study has been done on the possibility of establishing a symbiotic relationship between these fungi and lily. For this purpose, this study was performed to investigate the effect of different species of mycorrhizal fungi, including Glomus intraradices, Glomus etunicatum, Glomus mosseae and Glomus clorum on yield of Lily longiflourm and Lily ledebourii.This research carried outas a factorial in a Completely Randomized Design with three replications. The results showed that the root of L. longiflourm and L. ledebourii has developed a symbiosis at an acceptable level and the interaction of mycorrhiza on two species of lily is significant on investigated traits. The highest of root colonization percentage was observed in L. longiflourm inoculated with G. etunicatum, while, there was the lowest of root colonization percentage in L. ledebourii inoculated with G. clorum and L. ledebourii without inoculation. Also,the highest and lowest of plant height was observed in L. longiflourm inoculated with G. etunicatum and L. ledebourii without inoculation, respectively.Interaction effect oflily×mycorrhiza showedthe highest absorption of phosphorus, iron and zinc was observed in L. longiflourm and L. ledebourii inoculated with G. etunicatum. Actually,the results of this study indicate to affect symbiotic of G. etunicatum on growth and nutrients uptake that provides background to investigate the feasibility of its application to improve plant growth in lily.
