Abstract
This experiment was investigated on the consumption of the stored foods in the seeds in germination of various species (dent, flint, sweet and pop). (1) The stored foods of sweet corn were consumed most rapidly, then pop, flint and dent corn followed in order. (2) In the dent corn, the development of seedlings at the time of endosperm exhaustion was the growth stage of the 4th foliage leaf and 10.2 roots, in the flint corn, the 4th foliage leaf and 9.6 roots, in the sweet corn, the 3rd foliage leaf and 6.0 roots, and in the pop corn, the 3rd foliage leaf and 4.9 roots, at the mean soil temperature of 24.9°C. (3) The consumption curves of the stored foods in endosperms and the growth curves of seedlings are represented by application of the ROBERTSON's formula log x/(A-x)=K(t-t1). (4) The suspension of dry weights in seedlings appeared after the time of endosperm exhaustion. (5) The increase of dry weights in roots was slow in the early period and rapid in the following period and it was not recognized to decrease till the time of endosperm exhaustion.
