Effects of Isosmotic Concentrations of Inorganic and Organic Substrates on Entry of Water into Corn Roots

摘要: The data are interpreted as indicating that the osmotic pressure of substrate is one primary factors in controlling rate entry water into roots. It also recognized character solute and toxicity salts or ions may have a significant bearing on function intake, further experiments planned-especially with mixed salts. conflicting regarding effect organic substrates discussed light other work. results inorganic indicate that, under conditions these experiments, no differences intake occur when isosmotic pressures Na2SO4, NaCl, CaCl2 used single
