Localization of axillary meristems during different stages of radish ontogenesis

An analysis of axillary meristem (axillary bud) localization of radish (Raphanus sativus L. cv. Tetra-I?ówiecka) was undertaken on vernalized (flowering) and unvernalized (vegetative) plants. It has been shown that the localization of these meristems can be different on successive nodes of the same plant and is connected with the development stages of the plants. The axillary meristems can arise on the stem as well as in the leaf axil or on the base of the subtending leaf. The localization of axillary meristems has been discussed in relation to growth directions and growth correlations inside the meristematic region of the shoot apex.
