Mechanisms of Phosphorus Acquisition for Ponderosa Pine Seedlings under High CO2 and Temperature
To test the hypothesis that elevated atmospheric CO # and elevated temperature, simulating current and predicted future growing season conditions, act antagonistically on phosphorus acquisition of ponderosa pine, seedlings were grown in controlled-environment chambers in a two temperature (25}10 °C and 30}15 °C)¬two CO # (350 and 700 μl−") experimental design. Mycorrhizal seedlings were watered...
متن کاملKinetics of phosphorus absorption by mycorrhizal and nonmycorrhizal tomato roots.
Kinetics of P absorption were investigated in mycorrhizal (Glomus fasciculatus) and nonmycorrhizal tomato (Lycopersicon esculentum) roots to determine why increased ion absorption by mycorrhizae occurs. Initial rates of absorption of (32)P were measured at 1 to 100 micromolar KH(2)PO(4) (pH 4.6). Absorption rates of mycorrhizae were about twice those of control roots. Augustinsson-Hofstee analy...
متن کاملNon-nutritional stress acclimation of mycorrhizal woody plants exposed to drought.
Mycorrhizal enhancement of drought resistance of two woody plant species, loblolly pine (Pinus taeda L.) and rose (Rosa hybrida L. cv. Ferdy), occurred independently of phosphorus nutrition. Mycorrhizae tended to alter root morphology and carbon allocation patterns of shoots and roots. Increased drought resistance of mycorrhizal plants was in part attributed to drought-induced colonization by m...
متن کاملPhosphorus Inflow into Two Species of Clover Root with Different Morphology Colonized by AM Fungi
The effects of arbuscular mycorrhizal (AM) fungi on growth and phosphorus (P) inflow into two species of clover plant with different root morphology were studied. The experiment was arranged as a randomized complete block design consisting of a 2×3×3 factorial combination of two clover species (Trifolium alexandrinum L. and Trifolium pratense L.), three mycorrhiza states (without mycorrhiza, Gl...
متن کاملEffect of Waterlogging on Mycorrhizas of Radiata Pine and Douglas Fir
Radiata pine (Pinus radiata D. Don) and Douglas fir (Pseudotsuga menziesii (Mirb.) Franco.) seedlings were subjected to waterlogging periods of 1, 2, 4, 3, and 16 weeks. Phosphorus-32 uptake and succinic dehydrogenase activity of waterlogged mycorrhizas were measured and compared with non-waterlogged mycorrhizas. After 2 weeks of waterlogging Douglas fir mycorrhizas absorbed less P than control...
