One commonly used bioassay is seed germination. In current research study effect of contami...
گونه Puccinellia distans گیاهی چندساله و مرتعی از تیره گندمیان است. در این تحقیق برای بررسی اثر پرایمینگ بر جوانهزنی بذر گونه مذکور، آزمایشی در قالب طرح آماری کاملاً تصادفی در 4 تکرار انجام شد. تیمارهای پرایمینگ بذر عبارت بودند از: سه سطح اسید سالیسیلیک (100، 200 و 300 میلیگرم در لیتر)، سه سطح اسید جیبرلیک (125، 250 و 500ppm ) و دو سطح اسید اسکوربیک (100 و 300 میلیگرم در لیتر). مدت زمان پرایم...
A lot of salt-affected soils in the world are also affected by compaction and waterlogging due to shallow water tables or decreased infiltration sodicity. Waterlogging cause reduced oxygen exchange (hypoxia). Research on combined impacts salinity hypoxia turfgrass growth is limited. The interactive effects availability nine perennial ryegrass entries (Lolium perenne L.) one alkaligrass [Puccine...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
