摘要:

Leaf content of Ca remained fairly constant over three dilutions of nutrient solution. K content of the leaves fell with dilution. Porosity of the rooting medium had no effect on Fe, Cu, Mg, K in leaves but Ca and Zn decreased linearly with increasing porosity. Cation exchange capacity of the roots was not affected by porosity but there was a nutrient effect.
