Abstract

The effect of thiamin application on the respiration of the following three kinds of horticultural plants, potatoes, sweet potatoes and kidney beens, has been studied by the conventional WARBURG manometry.
The results obtained were as follows:
1. The thiamin solution of moderate concentration added to the leaves and roots, increased their respiration.

2. The calculated data on metabolic rapidity by the conventional WARBURG method, indicates that the thiamin solution added moderately advances the metabolic activities of the plants.
3. By adding thiamin, the values of respiratory quotient of leaves are approaching to 1.0. In my opinion, this result seems to indicate that thia-min is useful for decomposition of sugar or smooth oxidation of carbohydrates in leaves.
