Abstract
The effect of foliar sprays of vitamin B1 on the photosynthesis of the following four kinds of hor-ticultural plants, namely, sweet potatoes (var. Norin No. 1), kidney beans (var. Masterpiece), potatoes (var. Danshaku) and cabbages (var. Nagaokakohai), have been studied by the method determining the rate of absorption of carbon dioxide by leaves under natural conditions, or of the conventional WARBURG manometry. The conclusion obtained was as follows. The thiamine solution of moderate concentration sprayed on leaves, promoted their photosynthesis.
