On the consumption of the stored foods in the seeds during germination of cereals. : (4) Relation to the sowing depth of wheat, barley and oats.

[摘要] 1. Effect of the depth of sowing, i. e. 1 cm, 3 cm, and 5 cm-depth, of wheat, naked barley, hulled barley and oats upon the consumption of stored foods in endosperms and upon the early growth of plants was studied. 2. The process of consumption was identical and the endosperm exhaution occurred at the same time in all lots of each kind of plants. 3. The dry weight of plumules was generally heavier and that of radicles was lighter under deeper sowing. 4. The development of foliage leaves was promoted under shallower sowing. 5. In all 5 cm-depth lots, the foliage leaves appeared already from the coleoptiles under soil, but the appearance of plumules on the surface of soil was very irregular, because of their insufficient penetrating power through the soil. As the stored foods in seeds were almost exhaused under soil, in all 5 cm-depth lots the 5 cm-depth sowing might be very disadvantageous to the following growth of plants.
