Seedling vigor and diastatic activity of dent corn as related to composition of endosperm and stage of maturity
1928
Tascher, W.R. | Dungan, G.H.
In a study of the influence that the composition of the endosperm and stage of maturity of seed corn have on the diastatic activity and vigor of seedlings during germination the following phenomena were revealed. 1. During the germinative process, radicles emerged more rapidly and plumules less rapidly in early harvested corn than in mature seed. 2. Corn harvested in the mature stage produced heavier sprouts than that harvested in the milk, glaze, or dent stages. 3. Horny corn produced sprouts that were 0.148 gram heavier, as an average, than those from floury corn with odds of 3,332 to 1 that this difference was significant. 4. Tests made during the germination of corn showed a relative diastatic activity of 4.23 for horny corn and 4.05 for floury corn with odds sufficiently high to indicate significance.
