Axillary meristems are formed in all mainstem leaf axils of 2-mo-old hoop pines (Araucaria cunninghamii Aiton ex D Don) not occupied by first order branch buds. They have no bud-like organization or vascular connections and remain in this little differentiated and quiescent state unless stimulated to bud formation by release from apical dominance. With increasing plant age and hence increasing stem diameter, the meristems are not abscised via periderm formation, nor do they differentiate into… 

Axillary Meristems and the Development of Epicormic Buds in Wollemi Pine (Wollemia nobilis)

The study shows that, unlike most conifers, W. nobilis possesses long-lived meristematic potential in most, if not all, leaf axils, and unlike other araucarias that have been investigated, many of the meristems in the orthotropic main stem will slowly develop into bud primordia beneath the bark in intact plants.

Partial shoot reiteration in Wollemia nobilis (Araucariaceae) does not arise from 'axillary meristems'.

Axillary meristems in Wollemia characterize the leaf axils of trunk axes so that the origin of reiterated shoots is clear and demonstrates limited understanding of branch initiation in trees generally.

Epicormic buds in trees: a review of bud establishment, development and dormancy release.

Four different developmental strategies for epicormics based on characteristics of meristem development are described, showing control over epicormic bud dormancy is complex, but it is clear that the traditional view of auxin-mediated dormancy release is incomplete.

Ontogeny of proventitious epicormic buds in Quercus petraea. I. In the 5 years following initiation

The Epicormic potential in Q. petraea is characterized by a balance between the epicormic buds in apparent rest, enclosing meristematic areas and secondary bud primordia, and their mortality over the years.

Development of supernumerary buds from the axillary meristem of pea, Pisum sativum (Fabaceae)

Examination of leaf axil anatomy and external morphology indicated that new buds were derived from the axillary meristem, which exhibited strong apical dominance whereas WL5951 plants (rms-2) contained branches at several nodes.

Epicormic strand structure in Angophora, Eucalyptus and Lophostemon (Myrtaceae): implications for fire resistance and recovery

The outer portion of epicormic strands excised from the bark of large diameter stems of 18 Eucalyptus species, two Angophora species and Lophostemon confertus was examined anatomically in semithin sections and the strands appeared to have a reduced regenerative potential in the outer bark.

Buds, bushfires and resprouting in the eucalypts

The present review concentrates on axillary buds, their subsequent development into epicormic or lignotuber buds and their degree of protection from fire, which seems best adapted to regeneration after fire, rather than damage from insects, storms or drought and this also correlates with ecological observations.

Root suckering in a Triassic conifer from Antarctica: paleoecological and evolutionary implications.

The production of root suckers in Notophytum indicates that some of the trees growing in polar forests during the Triassic could respond to environmental stresses by regenerating their vegetative structures and had the potential to reproduce vegetatively.

Axillary Meristem Ontogeny in Araucaria cunninghamii Aiton ex D. Don

The presence of axillary meristems in apparently blank leaf axils from the main stem of 2-year-old Araucaria cunninghamii is demonstrated, which is apparently unique amongst conifers in possessing distinct, long-lived, exogenously initiated meristematic appearance and bud primordia in macroscopically blank Leaf axils.

Morphology and development of the primary and accessory buds of Eucalyptus regnans

The widened concept of the axillary meristem shifts attention from individual buds to the continuous generative powers of theAxillaryMeristem and helps to explain the outstanding capacity of the eucalypts to produce new shoots.

Leaf Axil Anatomy of the Araucariaceae

Well defined, persistent meristems, which possess neither a bud-like organisation nor vascular connections with the central vascular cylinder, were found in the apparently blank leaf axils of six

Role of water relations and photosynthesis in the release of buds from apical dominance and the early reinvigoration of decapitated poplars

The results suggest that after a brief moisture stress, decapitation increases moisture availability by increasing the root/shoot ratio and by reducing shoot competition for moisture, which leads to the acceleration of growth observed when plants are reinvigorated by decapitation.

The origin and morphology of epicormic branches in Rocky Mountain Dougas-fir (Pseudotsugamenziesii var. glauca (Beissn.) Franco) was studied by dissecting pole-sized trees. Epicormic shoots arose

SUPPRESSED BUDS EMBEDDED IN THE BARK ACROSS THE BOLE AND THE OCCURRENCE OF THEIR CIRCULAR VESSELS IN FICUS RELIGIOSA

It is found that the lateral swellings are suppressed buds which are embedded in the outer bark which forms secondary xylem and phloem in F. religiosa.

Seed production in Araucaria cunninghamii—the influence of biological features of the species

Several of the biological features of Araucaria cunninghamii have had a major impact on the development of techniques for the production of high quality seed, including the rigidly defined branching system, wide interclonal variation in flowering season, intermittent flowering, the pollination mechanism, seed structure and grafting incompatibility.

On the Comparative Anatomy and Affinities of the Araucarineae

Jeffrey, in reading specialisation into the structure of the Araucarinese, and in calling in question their connection with the Cordaitese, has done much to permit the Lycopod theory of the ancestry of the Conifers to become the rival of the CordAitean.

Spatial arrangement of lateral buds at the time that they form on leaders of Picea and Larix.

Lateral buds were formed on Piceasitchensis (Bong.) Carr in April–May before the leaders emerged from the winter buds, and seemed to be evenly (not randomly) distributed among the lateral buds.
