Metabolic aspects of the transport of ions by cells and tissues of roots

摘要: There is no clear cut viewpoint concerning the mechanism of transport solutes into and within roots that applicable to all plants solutes. Most attention has been given ionised species, particularly those are not incorporated organic molecules, e.g. K+, Na+, Ca+ + Cl−. Ions rapidly metabolised such as NO 3 − , SO 4 H2PO give rise special problems do uncharged sugars become charged during entry by phosphorylation.
