Differential Resistance to Botryosphaeria ribis Among Cercis Taxa
The eastern redbud (Cercis canadensis L.) is a popular woody ornamental plant native to eastern North America that is planted in the landscape chiefly for its showy early spring bloom. The genus Cercis (family Fabaceae) contains, depending on author, 7 to 13 species or subspecies that occur in North America, Europe, and Asia (4,7,8). Species range in size from small shrubs to trees, tolerate fu...
متن کاملDependence of photosynthetic rates on leaf density thickness in deciduous woody plants grown in sun and shade.
Comparisons of photosynthetic rates were made on leaves of ten species of woody dicotyledons grown in the field under full sun or under a canopy which transmitted approximately 18% of full light. Photosynthesis and dark respiration were measured and compared on various bases: area, chlorophyll, fresh weight of lamina, density thickness (fresh weight per unit area), and protein.Light-saturated p...
متن کاملLeaf water relations and maintenance of gas exchange in coffee cultivars grown in drying soil.
Plant water status, leaf tissue pressure-volume relationships, and photosynthetic gas exchange were monitored in five coffee (Coffea arabica L.) cultivars growing in drying soil in the field. There were large differences among cultivars in the rates at which leaf water potential (Psi(L)) and gas exchange activity declined when irrigation was discontinued. Pressure-volume curve analysis indicate...
متن کاملPhotosynthesis and Biomass Allocation in Oak Seedlings Grown under Shade
Northern’ red oak (Quercus rubra L.) (NRO) and white oak (0. alba L.) (WO) acorns were sown into wooden plots and grown under 30 percent shade screen (30 percent S) or 70 percent shade screen (70 percent S). Seedlings grown under full sun were the controls (C). At the end of the first year, the 30 percent S NRO had 30 percent greater seedling dry weight (DW) than C seedlings. No growth differen...
متن کاملResponse of three eastern tree species to supplemental UV-B radiation: leaf chemistry and gas exchange
Quantitative changes in foliar chemistry in response to UV-B radiation are frequently reported but less is known about the qualitative changes in putative UV-screening compounds. It has also not been conclusively shown whether qualitative differences in screening compounds or differences in localization patterns influence the sensitivity of plants to damage from UV-B radiation and there is some...
