| چکیده | ||
| گونههای شورروی بهدلیل سازگاری با شرایط خاص مناطق خشک و بیابانی میتوانند بخشی از نیاز علوفهای دام را در اوایل بهار، تابستان و بهویژه اواخر پاییز تأمین کنند. بااینحال، اطلاعات کمی در مورد ارزش غذایی این گیاهان در دسترس است. از سوی دیگر، شوررویها (هالوفیتها) دارای تغییرات قابل توجهی در ارزش غذایی خود هستند. بنابراین، آگاهی از کیفیت علوفه شوررویها در هر مرحله فنولوژیک علاوه بر اینکه به بهرهبرداران در مناطق خشک و بیابانی کمک میکند تا گونههای گیاهی مناسب را برای کاشت در برنامههای شورورزی انتخاب نمایند، بلکه باعث میشود زمان مناسب چرا برای دستیابی به عملکرد بیشتر دام در اراضی شور نیز تعیین شود. در این تحقیق، اثر مراحل مختلف فنولوژیک بر شش فاکتور مؤثر در کیفیت علوفه دو گونه مرتعی Atriplex leucoclada و Suaeda fruticosa بررسی شد. نمونههای گیاهی در سه مرحله فنولوژیک شامل رشد رویشی (اواخر خرداد) گلدهی (نیمه شهریور) و بذردهی (آبان) از اراضی شور در گرمسار، استان سمنان جمعآوری شدند. دادهها بهصورت آزمایش فاکتوریل در قالب طرح کاملا تصادفی تجزیه واریانس شدند. مقایسه میانگینها با آزمون چند دامنهای دانکن انجام شد. نتایج نشان داد که اثر مراحل فنولوژیک و اثر متقابل مراحل فنولوژیک در گونه بر کیفیت علوفه در سطح آماری یک درصد معنیدار بود. حداکثر کیفیت علوفه در مرحله رشد رویشی بهدست آمد و پس از آن کیفیت علوفه تا مرحله بذردهی کاهش پیدا کرد. بهطور کلی، نتایج این تحقیق حکایت از برتری گونهfruticosa Suaeda از نظر ارزش غذایی نسبت به گونه Atriplex leucoclada داشت، بهطوریکه میتواند بهعنوان منبع جدید علوفه در اراضی تحت تأثیر شوری که سایر منابع مرسوم علوفه امکان رشد و تولید در این اراضی را ندارند در نظر گرفته شود. | ||

| چکیده [English] | ||
| Due to the adaptability to arid and desert conditions, halophytes could supply a part of livestock forage requirement in early spring, summer, and especially autumn. However, there is little information on the forage quality of these plants. On the other hands, halophytes vary considerably in their nutritive value not only among species but also among phenological stages. Therefore, knowledge on forage quality of halophytes at each phenological stage could help the beneficiaries in arid regions to opt proper species for cultivation in haloculture programs as well as determining the suitable time for livestock grazing. In the present study, the effects of phenological stages on six forage quality traits were investigated for two halophytes ie., Atriplex leucoclada and Suaeda fruticosa. Plant samples were collected from saline lands in Garmsar, Semnan Province. The study was conducted in a completely randomized design with three replications. The results showed that the effects of phenological stages and species on forage quality were significant (P<0.01).The highest forage quality was obtained at vegetative growth stage and then it declined at the seeding stage. Overall, our results clearly indicate the higher forage quality of Suaeda fruticosa as compared with Atriplex leucoclada. Therefore, Suaeda fruticosa could be introduced as a new source of forage in saline lands on which other conventional fodders have no chance to grow and yield. | ||
