Abstract. Scientific novelty and practical significance. The increasing rates of soil degradation processes in the southern regions Russia make it urgent to increase productivity agricultural land, stabilize ecosystems restore potentially valuable forage vegetation. Phytomeliorative reconstruction low-productive lands is great importance for ensuring sustainable development region national food...
With the exception of the undesirable characteristic of summer dormancy and the accompanying low aesthetic value, crested wheatgrass has many desirable characteristics in semiarid environments, making it a promising candidate for lower water use turf. Using a population of 27 half-sib families, this study characterized the underlying genetics of turf quality (based on a 1–9 rating scale) of cre...
Limited availability of herbage during the cool season creates a problem of a supply of nutrients for livestock producers throughout the southern Great Plains of the USA and, particularly, on small farms where resource constraints limit possible mitigating strategies. Six coolseason grasses were individually sown into clean-tilled ground, no-till drilled into stubble of Korean lespedeza [Kummer...
پیشتیمار بذر موجب بهبود صفات جوانهزنی و استقرار گیاهچه و افزایش کارایی بذر در شرایط تنشهای محیطی میشود. به منظور تعیین اثر پیشتیمار جیبرلیک اسید بر رفتار جوانهزنی گیاه مرتعی علف گندمی (agropyron elongatum) تحت شرایط تنش بحرانی خشکی با استفاده از پتانسیل 12- بار ایجاد شده با پلیاتیلنگلایکول، آزمایشی به صورت فاکتوریل در قالب طرح کاملاً تصادفی با چهار تکرار طراحی و اجرا شد. بذور به مدت 12 ...
Petroleum hydrocarbons as organic contaminants are among the materials that pollute the soil. These compounds and the resutant stress to plants limit selection of suitable species to be planted in hydrocarbon contaminated sites. The aim of this research was to determine the effects of petroleum compounds on germination and morphophysiological characteristics of wheatgrass (Agropyron desertorum)...
