Carbon gain and hydraulic limits on water use differ between size classes of Larrea tridentata
Juvenile woody desert perennials often exhibit higher rates of transpiration than co-occurring adults, which may facilitate establishment by increasing carbon gain when water is plentiful, but increase the risk of hydraulic failure during drought. We tested three hypotheses regarding the role of hydraulic limits in two size classes of Larrea tridentata: 1) small plants grow faster and use more ...

this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
15 صفحه اولInfluence of the Soil Water Content and Distribution on Both the Hydraulic and Transpiration Performance of ‘Manzanilla’ Olive Trees
This work was made with mature ‘Manzanilla’ olive trees in an orchard of a semi-arid area in southern Spain. Three water treatments were considered: Rainfed, in which the trees had rainfall as the only source of water supply; FAO, in which the trees were under localized irrigation to replace the crop water demand, with some roots left in drying soil; Pond, in which the whole rootzones of the tr...

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
Hydraulic limits on maximum plant transpiration and the emergence of the safety-efficiency trade-off.
Soil and plant hydraulics constrain ecosystem productivity by setting physical limits to water transport and hence carbon uptake by leaves. While more negative xylem water potentials provide a larger driving force for water transport, they also cause cavitation that limits hydraulic conductivity. An optimum balance between driving force and cavitation occurs at intermediate water potentials, th...
