Abstract
In the wheat, the development of seedlings at the time of endosperm exhaustion is the growth stage of the 3 rd foliage leaf and 5.9 roots, in the naked barley, the 2 nd foliage leaf and 4.6 roots, and in the hulled barley, the 2 nd foliage leaf and 5.8 roots, at the mean soil temperature of 14.8°C. 2. The consumption curves of the stored foods in seeds and the growth curves of seedlings are represented by application of the ROBERTSON'S formula log x/(A-x) = K(t-t1). 3. The inflection points in the curves of the top dry weights appear 1∼3 days later than those in the curves of the stored foods dry weights. 4. The stored foods in the hulled barley were consumed more rapidly in the middle period than those in the other plants. This, with the slowness of the consumption in the early period, may represent the speciality of germination in the hulled barley.
