Regulatory dynamics of axillary bud competition in Arabidopsis
… of a plant depends on the activity of its axillary buds, which are continuously produced during development. Each axillary bud can either stay dormant or activate to form a branch, giving rise to a large number of possible branching forms. Whether a bud activates depends on the integration …

The effect of 6-benzylamino purine on axillary bud growth of Ilex crenata Thunb. 'Rotundifolia'
… timing of BA application at various phases of bud development of Ilex crenata Thunb. 'Rotundifolia' were studied. Foliar applications of BA at 800 ppm to unbranched rooted cuttings enhanced axillary bud development resulting in well branched Iiners. Axillary bud development of rooted cuttings …

Efficacy of Sucker Control Method and Effect of Topping Height on Axillary Bud Growth in Dark Fire-Cured Tobacco
The removal of terminal buds (topping) and sucker control are two practices that have an impact on yield and quality of dark tobacco (Nicotiana tabacum L.). Topping breaks apical dominance and encourages the growth of axillary buds (suckers). Following topping, growth regulator chemicals known as …

Height control of Eschscholtzia californica using ancymidol, cycocel, and limited inductive photoperiod
… with LIP included an increasing number of bud abortions and plants remaining vegetative, while the number of axillary buds decreased. Ancymidol [alpha-cyclopropyl-alpha-(4-methoxyphenyl)-5- pyrimidinemethanol] at 35, 45 and 50 ppm reduced stem length, but had no effect on peduncle length. …

The role of strigolactone and auxin in the regulation of shoot branching
… role of strigolactone and auxin in controlling bud growth dynamics and their effect on plant branching levels and development more generally. Firstly, I present a novel molecular mechanism for strigolactone perception, developed in collaboration with Prof. Ning Zheng’s group; I then link …

Floral initiation in <i>Rudbeckia hirta</i>: limited inductive photoperiod, polyamines and cytokinins
… rib meristem commenced after approximately 8 LD. Axillary bud development and final plant height were dependent on the number of inductive LD received. Polyamines have been linked to floral initiation and, in this study, were strongly correlated to the stage of floral initiation. As initiation …

The complex foraging strategy of the specialised gallfly Urophora cardui (Diptera: Tephritidae) for host plants (Cirsium arvense, Asteraceae)
… against conspecifics. The females lay eggs into axillary buds in order to initiate gall development. Male and female body size, measured as weight at eclosure or capsule width, was not correlated with male respectively female longevity. Males lived shorter than females. Capsule width of males and …

Influence of ethephon on growth and flowering of flue-cured tobacco
… and allow production of additional leaves from axillary bud. This practice requires additional labor and increases production costs. Objectives of this study were to 1) determine how application timing, rate, localization, and on-plant duration of ethephon (2-chloroethylphosphonic acid) …

Efficiencies of Mass Encapsulation in Alginate of Vegetative Explants
… Nodal segments, each containing a single axillary bud, were harvested and cut to 4mm prior to mass encapsulation. Results showed that using 2.75% alginate with a concentration of 60 or 80 mM calcium chloride produced an alginate mass, or “cookie”, which was able to hold together during …

The adaptive potential of plant endopolyploidy in response to herbivory
… to maximize rapid regrowth (particularly in axillary bud break and stem elongation), recent studies have targeted possible mechanisms for facilitating rapid regrowth in overcompensating organisms. One possible mechanism is the replication of the genome without mitotic cell division via an …
