Origin and Development of Axillary Buds: Betula Papyrifera Marsh. And Euptelea Polyandra Sieb. Et Zucc.

Axillary Bud Development in Populus deltoides. II. Late Ontogeny and Vascularization

“…The axillary buds of many plants possess secondary buds in the axils of their cataphylls (Garrison, 1955;Tucker, 1963;Brundell, 1975), and it would be instructive to know more of their origin and manner of vascularization.…”

“…DIsCUSSION-Morphological studies of mature axillary buds of dicotyledons often include descriptions of the vascular anatomy as observed on transverse sections extending from the bud base upward (Reeve, 1943;Garrison, 1949aGarrison, , b, 1955Shah, 1968;Shah andUnnikrishnan, 1969, 1971). …”

“…Each Cat subtended its own axillary bud, referred to as a secondary bud by Garrison (1949a) or a basal bud by Brundell (1975). Examination of buds at the position of LPI 5 that had elongated on older plants revealed that Cats 1 and 2 remained at the base of the branch, Cat 3 extended a few mm above Cats 1 and 2, and the fused structure consisting of Cats 4 and 5 often extended several cm above Cat 3.…”

Histogenesis of the Vegetative Shoot in Echinocereus

“…In 1946, Majumbdar and Datta reported that bud traces observed up to that time all originated in the bud primordium and differentiated basipetally. More recently, Garrison (1949) reported acropetal development of bud traces in Betula and Euptelea.…”

Histogenesis of the Vegetative Shoot in Echinocereus

“…More recently, Garrison (1949) reported acropetal development of bud traces in Betula and Euptelea. Moreover, the materials used for this study indicate that the procambium later associated with the areole differentiates aeropetally in continuity with older procambium.…”
