Auxins in Immature Maize Kernels

Article metrics


ETHER extracts of maize-kernel pulp at pH 6 contain only part of the growth-promoting activity of the kernels. The juice expressed from the ether-extracted kernels is still highly active in the straight-growth test. In Table 1 the activity of the expressed juice from ether-extracted maize kernels is compared with that of an equivalent concentration of ether-extractable material.
