“…For the purpose of the study, only one European plum variety, 'Stanley', was used. Although this variety branches relatively well in nurseries (Wolf et al, 2018), in this study 'Stanley' produced lateral shoots only on Pumiselekt (2.5 feathers) and Penta (2.3 feathers) rootstocks and were of a very poor quality. The poor quality branching of variety 'Stanley' could be associated with the poor growth of this variety, which reached an average height of only 16.45 ± 2.64 cm.…”

The main objective of this work was to verify the possibility of shortening the time needed to produce nursery trees of plums, in view of the economic profitability in nursery production. To achieve this goal, rootstocks Citation®, Ishtara®, Penta®, Torinel®, Pumiselekt and St. Julien (from Wädenswil) were chip budded in the springtime with ‘Shiro’, ‘Angeleno’®, ‘Black Amber’, SLE2014/1, ‘Fertility’ (Asian type plums) and ‘Stanley’ (European type plum) as a control. At the end of the vegetation period, height (from the grafting position), trunk diameter above the place of budding and the number of shoots was recorded for each tree. The Penta® rootstock was evaluated as the most efficient, while ‘Shiro’ variety was evaluated as the most suitable variety. The best variety/rootstock combination was the combination of ‘Shiro’ on Ishtara® rootstock, where 100% of the budded trees reached an average height of 33.0 ± 3.6 cm. The highest trees of an average of 68.3 ± 4.6 cm were recorded for the combination of SLE2014/1 on Torinel® root-stock.

Of the many chemicals tested by Wolf et al (2018), the most effective and available branching agent was the cytokinin 6-benzyladenine (BA) often applied with gibberellins GA 4/7 or GA 3 (Hrotkó et al 1998;Hrotkó et al 1999;Elfving, Visser 2006a;Koyuncu, Yildirim 2008;Moghadam, Zamanipour 2013). Leaf pinching is a mechanical method that removes (by pinching out) some of the youngest leave blades while the growing tip (meristem) stays intact (Neri et al 2004).…”

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.
