Description

This paper deals with the results of experiments on the relation between the occurence of ripe-rot disease of grapes and the seasonal change of reducing sugar, hydrogenion concentration and nitrogenous compound in the fruit.
Reducing sugar and total nitrogen increased with the process of ripening of fruits. Ammonium and non-proteid nitrogen increased remarkably in well-developed fruit. These components may be available for the fungus growth, and it might be possible that the increase of these substances might take a part for the occurence of the present disesae.
