WATER TRANSPORT THROUGH PLANTS--INTERNAL INTEGRATION OF EDAPHIC AND ATMOSPHERIC EFFECTS |
| Authors: | M. R. Kaufmann, Edwin L. Fiscus |
| Abstract:
Water transport through plants is influenced by plant structure along the transport pathway, physiological processes, and environmental conditions. Water movement follows standard transport principles, but the gradients and resistances within pathway segments are not independent of those in the rest of the transport system. In horticultural trees, water transport apparently is not strongly influenced by solute absorption by roots, partitioning of water for growth, or diurnal changes in stored water. Furthermore, the size of the absorbing root system, conducting tissue in the xylem, and leaf transpiring surface appear to remain in balance through physiological feedback mechanisms. | |
