Biomass Yield Stability of Switchgrass Cultivars
INTRODUCTION The development of viable bio-based energy systems offers many potential benefits relative to energy availability, national security, a cleaner environment, and associated economic rewards (DOE 2000). Largescale bioenergy use will require the deployment of environmentally acceptable energy crops and cropping systems for producing large quantities of low-cost, high-quality biomass f...
متن کاملYield and Physiological Responses of Modern versus Obsolete Cultivars Grown under Water-deficit Conditions
Year-to-year variability in yield is a major concern in U.S. cotton production. Recent literature and hypotheses indicate that this yield variability is mostly related to extreme environmental conditions, particularly high temperatures and drought, as well as a peak in genetic improvements in yield. It is speculated that modern and obsolete cultivars partition dry matter and energy pools differ...
متن کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Switchgrass ultimate stresses at typical biomass conditions available for processing
Biomass tensile and shear ultimate failure stresses were measured with the aim of identifying biomass ‘‘weakest mode of failure’’ or ‘‘natural fracture point’’ as a basis for future grinder designs. Switchgrass (Panicum virgatum L.) ultimate stresses were determined for Alamo and Kanlow varieties over ranges in maturity and moisture content. Alamo had greater ultimate tensile stress than Kanlow...
متن کاملYield and growth characteristics of sunflower cultivars inoculated by arbuscular mycorrhizal fungi under drought tension conditions
One of the new methods for optimum management and increasing the efficiency of water resources utilization in agricultural uses is the use of irrigation methods. Considering the importance of this issue, this research was carried out to determine the effect of mycorrhizal fungi on the yield of sunflower cultivars under drought tension conditions and as split split plots based on randomized comp...
