دگرآسیبی (آللوپاتی) به اثر متقابل گیاهان توسط مواد شیمیایی آزاد شده آن ها بر یکدیگر اشاره می­کند. مطالعه حاضر به منظور بررسی اثرات دگرآسیبی گیاه دارویی گل محمدی (Rosa damascene Mill) بر جوانه زنی بذر گندم (Triticum aestivum L.) انجام شد. آزمایش به صورت فاکتوریل در قالب طرح کاملا تصادفی در سه تکرار انجام شد. تیمارهای آزمایش شاهد و غلظت های مختلف (1، 2، 3، 4 و 5 درصد) عصاره آبی گلبرگ های خشک گل محمدی نمونه بوکان و خوانسار بودند که در سه تکرار انجام شد. نتایج این آزمایش نشان داد عصاره­ی گل محمدی با غلظت های ذکر شده، کاهش جوانه زنی را نسبت به شاهد در پی نداشت. عصاره ی آبی نمونه ی بوکان باعث کاهش معنی دار طول ساقه چه، طول ریشه چه، وزن خشک ساقه چه، وزن خشک ریشه چه و مقدار پروتئین محلول در گیاه گندم شد همچنین عصاره ی نمونه ی خوانسار بیشترین اثر بازدارندگی را بر صفات وزن تر ساقه چه و ریشه چه و مقدار قند محلول بر گیاه گندم داشت. جدول تجزیه‌ی واریانس نشان داد که تفاوت بین عصاره‌ها، تیمارها و عصاره × تیمار معنی‌دار (05/0 >P) بود. در هر دو گیاه بین وزن تر، خشک و طول ساقه چه و نیز بین محتوای پروتئین و قند محلول همبستگی مثبت معنی داری (9/0<r,05/0>P) وجود داشت.

چکیده [English]

Allelopathy refers to the interaction of plants with their released chemicals on each other. Allelopathic compounds play an important role in biodiversity and the ability to produce ecosystems.In order to investigate the effects of allelopathy on Rosa damascena Mill on germination of wheat (Triticum aestivum L.) seeds. The experiment was done as factorial based on completely randomized design with three replications. The distilled water treatments used as control and different concentrations (0, 1, 2, 3, 4 and 5%) of aqueous extract of dried Rosa flowers used as treatments. Rosa flowers were from Boukan and Khansar, the designwere completely randomized in three replications. The results of this experiment showed that the juice extract with the mentioned concentrations did not reduce germination as compared to the control.The aqueous extract of Boukan showed a significant decrease in plumulelength, radiclelength, plumuledry weight, radicledry weight, and soluble protein content in wheat. Also, the extract of Khansar showed the highest inhibitory effect on plumule fresh weight, radicle fresh weight and soluble sugar content on the wheat plant.The analysis of variance showed that the difference between the extracts, treatments and extract × treatment was significant (P <0.05). There was a significant correlation (P <0.05) between fresh weight, dry weightand length, as well as protein and sugar content in both plants.
