Summary

A study was made of the effect of Kitazin systemic blast fungicide on the ion uptake and leakage of rice roots. Parallel experiments were carried out on the growth rate and free amino acid content.

In the presence of 10-3 M and 5 × 10-4 M Kitazin the potassium and phosphate ion uptakes were effectively inhibited, while the K-ion leakage from the roots was abnormally high, due to change of cell-membrane permeability and damage. Also the free amino acid content was very low as compared to the control. The growth of the plants was markedly retarded.

At 10-4 M Kitazin and less, the effects exhibited were not injurious, but rather favourable.
