[ 1 ] - آثار تنش های شوری و خشکی بر روی جوانه زنی دو گیاه مرتعی Agropyron desertrum و Agropyron elongatum
The effect of various concentrations of drought and salinity solutions on germination of two species known as Agropyron elongatum and Agropyron desertrum were investigated according to factorial design. This investigation contains three repetitions, nine drought levels (0,2,4,6,8,10,12,14,16), and seven salinity levels (0,2,4,8,16,33,64). 50 seeds of any species were cultivated in Petri dishes ...
[ 2 ] - تأثیر تیمار‌های مختلف بر شکست خواب و تحریک جوانه‌زنی بذر گونه (Atriplex leucoclada Boiss)
گونۀ Atriplex leucoclada Boissیکی از گونه‌های مهم بومی مراتع خشک و نیمه خشک ایران است که دارای محدودیت جوانه‌زنی و خواب بذر است. به منظور بررسی روش‌های مؤثر شکستن خواب این گونه، آزمایشی در قالب طرح کاملاً تصادفی با هشت تیمار شامل: تیمار سنباده با دو شمارۀ 100 و 200، تیمار هیپوکلریت: در زمان‌های 5، 10، 15، 20، 25 دقیقه، تیمار آب جوش: شامل غوطه‌ور کردن بذور در آب جوش به مدت 1، 5، 10، 15، 20، 25...

[ 4 ] - Investigation of cultivation of the Seidlitzia rosmarinus on vegetation and soil traits in Shahroud – Chah bagher Region
It is unavoidable for projects of rangeland improvement and development to use key species. One of the successful projects for rangeland improvement and development is to use seeding with technical knowledge, in order to have complex success in poor rangelands that are desert regions. The cultivation of environmentally adaption plants is one of the best biological methods to prevent desertifica...
[ 5 ] - Phytoremediation of nitrogen-contaminated soil by Atriplex lentiformis, Atriplex canescens and Atriplex leucoclada
In this study, the ability of three rangeland species Atriplex halimus, A. canescens and A. lentiformis to remove nitrate from soil in vitro (greenhouse) in a completely randomized design was investigated. For this purpose, potassium nitrate salt (KNO3) was used in four treatments control, 6.3 ppm, 9.5 ppm and 14.5 ppm in three repetitions. Plant species used in this study with an approximate...
[ 6 ] - Study of effective indicators on rangeland management in collective and private exploitation systems (In winter rangelands of Golestan province)
During the last few decades, one of the most important problems of Iran rangelands is how to manage ranch units, which are managed according to the grazing license, in one of the three common methods, council, collective and private exploitation. The most important tool for achieving sustainable development and natural resource management is property right. Considering the importance of range...
