این تحقیق با هدف بررسی اثرات محرک های شیمیایی جیبرلیک و سالیسیلیک اسید بر بهبود جوانه­زنی و حمایت گونه Cassia angustifolia تحت تنش با ترکیبات آللوپاتیک Eucalyptus camaldulensis در شرایط کنترل شده آزمایشگاهی پرداخته شد. تیمارها شامل پیش تیمار بذر با جیبرلیک اسید (۱۲۵، ۲۵۰ و ۵۰۰ پی‌پی‌ام) و سالیسیلیک اسید (100، 200 و300 میلی گرم در لیتر) و 5 غلظت (۰، ۲۵، ۵۰، ۷۵ و ۱۰۰ میلی‌گرم در لیتر) از ترکیبات آللوپاتیک حاصل از اندام‌های هوایی و زمینی اکالیپتوس بود که بصورت آزمایش فاکتوریل در قالب طرح پایه کاملاً تصادفی در چهار تکرار اجرا گردید. با توجه به نتایج حاصل از تجزیه واریانس اثر متقابل پیش تیمار و اللوپاتی بر کلیه صفات اندازه‌گیری شده در سطح یک درصد معنی‌دار بود. مقایسه میانگین‌ها نشان داد که عصاره اکالیپتوس اثر آللوپاتیک بازدارنده بر جوانه‌زنی بذر و رشد اولیه گیاهچه­های Cassia angustifolia دارد. به‌طوریکه پیش تیمار بذر با باعث بهبود درصد و سرعت جوانه‌زنی و رشد اولیه گیاهچه‌ها گردید. کاربرد تیمار جیبرلیک اسید با غلظت ۵۰۰  پی‌پی‌ام بیشترین تاثیر را بر بهبود جوانه‌زنی و رشد اولیه گیاهچه‌ها داشت. به‌طور کلی نتایج نشان داد که پاسخ گونه Cassia angustifolia به پیش تیمار بذر با جیبرلیک اسید مثبت است و تکنیک پیش تیمار بذر با غلظت ۵۰۰ پی‌پی‌ام جیبرلیک اسید قبل از کاشت اثرات بازدارنده ترکیبات آللوپاتیک اکالیپتوس را در مرحله جوانه‌زنی بطور معنی‌داری کاهش می‌دهد.

چکیده [English]

The aim of this study was to investigate the effects of gibberellic and salicylic acid on germination improvement and protection of Cassia angustifolia under allelopathic stress of Eucalyptus camaldulensis compounds in laboratory conditions. Treatments consisted of pretreatment with gibberellic acid (125, 250, and 500 ppm) and salicylic acid (100, 200, and 300 mg / l), and 5 concentrations of extracted allelopathic compounds of eucalyptus aerial and terrestrial organs (0, 25, 50, 75, and 100 mg / l). Each treatment had four replications and a factorial experiment in completely randomized design was performed. Results of analysis of variance indicated that the interaction effect of pretreatment and allelopathy on all measured traits was significant (p≤0.01). Means comparison showed that eucalyptus extract has allelopathic inhibitory effects on seed germination and early growth of Cassia angustifolia seedlings such that seed pre-treatment with chemical stimulants improved germination percentage and speed and also early growth of seedlings. Seed pre-treatment with gibberellic acid 500 ppm had the best effect on improvement of germination and early growth of seedlings. Overall, the results showed that Cassia angustifolia's response to seed pre-treatment with gibberellic acid was positive, and the seed pretreatment technique with gibberellic acid 500 ppm before planting decreased significantly the inhibitory effects of eucalyptus allopathic compounds at germination stage.
