“…Results from other studies indicate that cytokinin-GA products are effective for inducing sweet cherry buds to grow into shoots (Elfving and Visser, 2006;Jacyna and Puchała, 2004;Miller, 1983;Veinbrants and Miller, 1981). Results of the trials reported here…”

“…Sweet cherry trees exhibit strong apical dominance, producing vigorous, upright shoot growth with limited lateral branching, particularly in young trees (Elfving and Visser, 2006;Jacyna, 2002;Jacyna and Puchała, 2004;Jacyna et al, 2005;Miller, 1983). The interaction of endogenous auxins and cytokinins is thought to play a role in the control by apical dominance of lateral bud activity in the spring and during shoot development (Sachs and Thimann, 1967;Theron et al, 1987;Wickson and Thimann, 1958).…”

Improving lateral branch development in young sweet cherry trees without reliance on pruning is a desirable component of tree training programs, especially for high-density systems. Applications of two proprietary formulations of 6-benzyladenine and gibberellins A4 and A7 (Promalin, Valent Biosciences, Walnut Creek, Calif.; and Perlan, Fine Americas, Walnut Creek, Calif.) to individual buds or intact bark of unpruned sweet cherry central leader shoots at green-tip had little effect on lateral shoot growth from buds or on distribution of new shoot growth along the treated leader shoots. Scoring, nicking, or notching cuts alone also had inconsistent effects on shoot development and distribution. In some trials, bud removal (or disbudding, removing every fourth bud on 1-year-old shoots) produced limited improvement of lateral shoot development and vertical distribution. Combining nicking, notching, scoring, or bark scraping with the application of cytokinin–gibberellic acid solution to the cut area greatly improved both number of shoots developed and the numbers originating from the lower portions of treated leader shoots. Removing the physical barrier to bioregulator product contact with active tissues was a primary factor in improving treatment efficacy.

“…Most studies of the branching ability of sweet cherries have been done with vigorous rootstocks or in hotter and more climatically favourable regions (Hrotkó et al 1999;Neri et al 2004;Elfving, Visser 2006b;Koyuncu, Yildirim 2008;Moghadam, Zamanipour 2013). Evidence of effective treatments applicable to often suboptimal temperate zone conditions and to trees on lowvigour rootstocks is scarce (Baryla et al 2014).…”

The promising branching agent cyclanilide [1-(2,4-dichlorophenylaminocarbonyl)-cyclopropane carboxylic acid] is not permitted in the EU and the low vigour rootstocks preferred by growers make the branching of young sweet cherry (Prunus avium) trees difficult in the temperate zone production regions. To increase the number and length of new branches (“feathers”) on such trees, chemical (6-benzyladenine [BA], gibberellic acid [GA<sub>4/7</sub>]), mechanical (leaf pinching, summer notching) and various combined treatments were tested from 2015–2018. The numbers of feathers divided into three different lengths (1–10 cm, 10–30 cm and > 30 cm) were assessed as the main indicator of quality, supplemented with other morphological characteristics. Summer notching induced an insufficient number of feathers and led to some negative effects on the trees. The number of feathers from BA or BA with GA<sub>4/7</sub> treatment also was insufficient. The effect of pinching alone was variable. The number of all feathers generally was highest when pinching was combined with BA, regardless of the year or cultivar.

“…In recent decades cyclanilide, which acts as an auxin transport inhibitor (Pedersen et al, 2006), was tested as a promising branching agent of sweet cherry and apple trees (Elfving and Visser, 2006;Sazo and Robinson, 2011). Among plant growth regulators (PGR's) with inhibition effect, paclobutrazol (PBZ, anti-giberrelin) was used together with Promalin to produce compact and well branched sweet cherry trees (Jacyna et al, 1989).…”

“…Studies proved positive effect of 6-benzylaminopurine (6-BAP, cytokinin) and gibberellic acids 4+7 (GA4+7, gibberellins) in different concentrations and doses on branching of sweet cherry (Hrotkó et al, 1999;Elfving and Visser, 2006;Koyuncu and Yidirim, 2008) and plum trees (Magyar and Hrotkó, 2002). GA4+7 and 6-BAP have been commercially available in combination as Perlan, Promalin or Progerbalin LG and also separately as Paturyl (6-BAP), Globaryll (6-BAP) or Gibb plus (GA4+7).…”

Modern high quality nursery trees pruning as knipboom grow and crop significantly better during the first years after planting in the orchard. High quality nursery trees perform better in the first years after plantation in the orchard than average or low quality nursery trees. Nurserymen are focused on production of such trees in the shortest time (one year). However, fruit tree species and varieties differ in their abilities to produce these trees. The goal of this work was to increase the quality and branching of one-year-old nursery trees at two plum and two sweet cherry varieties by the treatments of 12 different preparations of plant growth regulators (PGRs). Before lifting, branching and trunk parameters were recorded. Data showed that Ethephone+Putrescine+GA4+7 and Ethephone+Putrescine+6-BAP significantly increased almost all parameters at both plum varieties. Both sweet cherry varieties were sufficiently branching with Globaryl+epibrassinolide treatment, however the lateral shoots of ‘Celeste’ sweet cherry variety were of low quality. The same was observed after treatment with Progerbalin+4-CPPU+Putrescine. Sweet cherry ‘Kordia’ branched very well after Globaryl and TIBA+PBZ treatments too, however, the lateral shoots after treatment with the latter preparation were of low quality. ‘Kordia’ trees after Globaryl treatment were branched in 94% of cases with more than four lateral shoots.
