1) The value of the critical reaction (Cr.) indicated by pHi (isoelectric point)〜pH, of the protoplasm of the embryo of the wheat and barley, is small at the beginning of water absorption, then gradually increases, and finally reaches to the maximum point when the germination commences. 2) The effect of ultra short wave on the germination of wheat seed appears in the change of the value of Cr. of the protoplasma, as soon the seed begins to absorb water. 3) The Cr. value of the protoplasm in the wheat embryo increases with the ripening of the seed, reaching to the maximum value at its full maturity. 4) Seeds on the ear of the wheat plant standing in field, biggin to germinate to rnake the so-called "viviparous head", as soon as the Cr. value of the protoplasm attains to the maximum value. 5) The afer-ripening of wheat seeds is found to affect the Cr. value of the protoplasm to an extent that the fact is enough to indicate some physiological processes to have took place.
