Cotyledon Expansion as a Bioassay for Cytokinins

open access: yesPlant Physiology, 1969
The activity of cytokinins in stimulating cell division formed the basis for the original techniques for their bioassay (12, 13) and for later modifications (6,7,8). In the subsequent decade, as various other activities of cytokinins blecame evident, numerous other types of stimulations have been employed in bioassays.

Size regulation of the lateral organ initiation zone and its role in determining cotyledon number in conifers

open access: yesFrontiers in Plant Science, 2023
IntroductionUnlike monocots and dicots, many conifers, particularly Pinaceae, form three or more cotyledons. These are arranged in a whorl, or ring, at a particular distance from the embryo tip, with cotyledons evenly spaced within the ring.
