Seedling Growth of Two Honey Mesquite Varieties Under CO2 Enrichment
Seedlings of 2 varieties of honey mesquite (Prosopis glandulosa var. glandulosa and P. glandulosa var. torreyana) were exposed to 2 concentrations of atmospheric carbon dioxide (CO2) (368 and 704 lmol mol ) in environmentally controlled glasshouses under near-optimal temperature and soil water conditions to determine if CO2 enrichment alters aboveand belowground growth responses. CO2 enrichment...
متن کاملgradual erasure of subjectivity: a study of samuel beckett’s trilogy in the light of postmodernism
ساموئل بکت بیشتر از هر نویسنده دیگری در نیم? دوم قرن بیستم با گفتارش زمان? ما را به آستان? از هم پاشیدگی کشانده است، آستانه ای که در آن مدرنیته با سرانجام گریزان اما غیرقابل اجتناب خود مواجه می شود. در این تحقیق روی مفهوم فردیت و محو آن در دوران پسامدرن تاکید شده و در طی آن سعی شده است که فردیت مدرن و پسامدرن در رمان های سه گانه بکت بررسی گردد. تحقیق حاضر یک بررسی کتابخانه ای و کیفی بر روی سه ر...
15 صفحه اولHerbage Response to Sagebrush Spraying
Information that is presently available makes chemical control of sagebrush (Artemisia’ tridentata) a practical operation. Yet additional information is needed regarding ecological responses to assure that the practice of spraying for sagebrush control will be used wisely. The economy of brush control must be determined by the amount of forage and meat products gained; however, the principal ob...
متن کاملCarbon dioxide enrichment improves growth, water relations and survival of droughted honey mesquite (Prosopis glandulosa) seedlings.
Low water availability reduces the establishment of the invasive shrub Prosopis on some grasslands. Water deficit survival and traits that may contribute to the postponement or tolerance of plant dehydration were measured on seedlings of P. glandulosa Torr. var. glandulosa (honey mesquite) grown at CO(2) concentrations of 370 (ambient), 710, and 1050 micro mol mol(-1). Because elevated CO(2) de...
متن کاملStem flow and porometer measurements of transpiration from honey mesquite (Prosopis glandulosa)
The objective of this study was to compare stem flow and porometer methods of measuring transpiration of honey mesquite (Prosopis glandulosa) trees on a semiarid site. Stem flow was measured using heat balance stem flow gauges. Porometer measurements of leaf stomatal conductance (gs) were made within foliage layers of each stem and scaled to transpiration values for the entire stem (Estern) usi...
