Plant Cell Water Relations. Jaja Amuenda. I. INTRODUCTIONIndependent of the species, plants require from the soil a water volume that overcomes its metabolic necessities. Through the transpiration process plants transmit to the atmosphere the majority of the water absorbed from soil (generally around 90%). From this perspective, it is noted that. plant water relations, as well as the consequenc es of an inadequate water supply. Broadly, the water state of a plant is controlled by relative rates of loss and absorption, moreover it depends on the ability to adjust and keep an ad equate water status. This will be considered throughout this chapter. 2. Absorption and water flow through plants Independent of the species, plants require fr. Plant-water relations. Water is the most abundant constituent of all physiologically active plant cells. Leaves, for example, have water contents which lie mostly within a range of 55–85% of their fresh weight. Other relatively succulent parts of plants contain approximately the same proportion of water, and even such largely nonliving tissues as wood may be 30–60% water on a fresh-weight.

It can be divided into two components, hydrostatic pressure P and osmotic pressure Paccording to eqn [1]. Add K. Annual Review of Plant Physiology Plant Molecular Biology Large negative values are also common, both in plants and the soil they are growing in. Pressure inlet Figure 3 Pressure chamber for measuring the water potential of a leaf. The upward movement of water in plants occurs in the xylem, which, in the larger roots, trunks, and branches of trees and shrubs, is identical with the wood.Plant Cell Water Relations. Jaja Amuenda.
