Gibberellins Stimulate Lateral Branch Development in Young Sweet Cherry Trees in the Orchard

nana plant2 Encodes a Maize Ortholog of the Arabidopsis Brassinosteroid Biosynthesis Gene DWARF1, Identifying Developmental Interactions between Brassinosteroids and Gibberellins

“…BR and auxin positively regulate each other's biosynthesis (Li et al, 2005;Kim et al, 2014), resulting in a positive regulatory loop. GA also influences plant height, branching, reproductive organ development, stomatal development, and disease resistance (Evans and Poethig, 1995;Eckardt, 2002;Saibo et al, 2003;Elfving et al, 2011).…”

Mechanisms of vegetative propagation in bulbs : a molecular approach

“…Auxin seems to interact with the hormone strigolactone to inhibit bud growth (Bennett and Leyser 2006;Brewer et al 2009;Liang et al 2010), while cytokinins directly activate outgrowth (Dun et al 2012;Shimizu-Sato and Mori 2001). Additionally, two other classical and antagonistic acting hormones, gibberellin and abscisic acid, involved in seed dormancy release and dormancy induction maintenance respectively, also seem to play a role in the control of axillary bud development and branching (Elfving et al 2011;Jiang et al 2009;Reddy et al 2013;Yao and Finlayson 2015;González-Grandío et al 2017). …”

Effect of the co-application of Promalin® at different bud phenological stages and notching at different distances on lateral branching of three sweet cherry cultivars (Prunus Avium L.) in central Chile

“…Growers require well-branched maiden trees for planting intensive orchards as feathered trees with wide angled secondary laterals provide earlier and higher yields (Hrotkó et al, 1999). Most of the sweet cherry cultivars exhibit strong apical dominance, particularly in young trees (Elfving and Visser, 2007). If not properly managed, scaff old branches and leaders of young trees produce hardly any laterals (Jacyna and Puchała, 2004).…”

“…Diff erent methods to increase branching have been examined. These methods included disbudding, deblading and notching among others (Neri et al, 2002;Zucconi, 2000;Elfving and Visser, 2007). Yet branching responses brought by these procedures are o en inconsistent (Elfving and Visser, 2007).…”

The mixture of Benzyladenine (BA) and gibberellic acid isomers (Promalin®) has been used as a branching agent in nurseries and in young cherry tree orchards.…”
