| چکیده | ||
| تنشهای محیطی،از جمله خشکی و شوری میتوانند نقش مهمی در کاهش رشد و عملکرد بخصوص در مرحله استقرار گیاهچه در اقلیمهای خشک و نیمه خشک ایران داشته باشند.بنابراین شناسایی خصوصیات گیاهان مرتعی مقاوم به تنش خشکی و شوری اهمیت زیادی دارد.به منظور بررسی تاثیر غلظت‌های مختلف خشکی و شوری بر جوانهزنی و رشد اولیه خارشتر (Alhagi maurorum)،دو آزمایش بصورت جداگانه در قالب طرح کاملا تصادفی در آزمایشگاه دانشکده کشاورزی بردسیر،دانشگاه شهید باهنر کرمان، با سه تکرار اجرا شد.تعداد 30 عدد بذر هم اندازه با محلول هیپوکلریت سدیم 10 % به مدت 30 ثانیه ضد عفونی شده و پس از سه مرتبه شستشوی بذرها با آب مقطر،در داخـل پتـریهـای 9 سانتیمتری روی کاغذ صافی واتمن شماره 2 قرار گرفتند.سـپس در آزمایش نخست برای ایجاد پتانسیل خشکی از محلول پلی اتیلن گلایکول (PEG6000) با غلظت‌های 1-، 5/1- و 2- مگاپاسکال و در آزمایش دوم از NaCl با غلظت های 100، 150 و 200 میلی‌مولار استفاده گردید.همچنین برای ایجاد سطح تنش صفر (شاهد) در هر دو آزمایش از آب مقطـر استفاده گردید نتایج نشان داد بذرهای خارشتر قادر بودند تا 2- مگاپاسکال پتانسیل خشکی و 200 میلی‌مولار پتانسیل شوری جوانه بزنند.اما افزایش تنش خشکی و شوری، درصد و سرعت جوانهزنی، شاخص بنیه بذر وزن خشک گیاهچه، طول اندام هوایی طول ریشهچه وزن خشک اندام هوایی و وزن خشک ریشهچه را بطور معنی داری کاهش داد ارزیابی پاسخ این گیاه به سطوح مختلف خشکی و شوری در مرحله جوانهزنی و رشد اولیه گیاهچه، از جهت تولید علوفه، حفاظت خاک و ارزش دارویی اهمیت دارد | ||

| چکیده [English] | ||
| Environmental stresses, including drought and salinity stress can play an important role in reducing plant growth and yield especially in the seedling establishment stage in arid and semi-arid climates of Iran.Therefore, identification of range plants tolerance to drought and salt is very important.To assay the effect of different concentrations of drought and salinity on germination and early growth of camelthorn(Alhagi maurorum) two experiments were performed separately in a completely randomized design with three replications in the laboratory of Bardsir Faculty of Agriculture, Shahid Bahonar University of Kerman.30 uniform seeds were sterilized with 10% sodium hypochlorite solution for 30 seconds and after washing the seeds three times with distilled water, they were placed in 9 cm Petri dishes on Whatman No. 2 filter paper.In the first experiment, polyethylene glycol solution (PEG6000) with concentrations of -1, -1.5 and -2 MPa was applied to obtain the osmotic potential, and in the second experiment, NaCl with concentrations of 100, 150 and 200 mM was used.Distilled water was also applied to make zero stress(control)in both experiments. Results showed that camelthorn seeds were able to germinate at -2 MPa of drought potential and 200 mM salinity potential.However, increasing drought and salinity stress significantly reduced germination percentage and rate, seed vigor index, seedling dry weight, shoot length, root length, shoot dry weight and root dry weight.Assessing the response of this plant to different levels of drought and salinity in the germination stage and early growth of seedling is important for forage production, soil protection and medicinal value | ||
