“…Veinbrants and Miller (1981) also reported that the application of Promalin increased the number of shoots from 4 to 11. Bennewitz et al (2010) found that in treated Lapins trees, the total number of lateral shoots (in most cases) significantly increased, while in Stella trees, the total feather length and the total number of lateral shoots were not affected by Promalin treatments. Jacyna et al (1989) suggested that Promalin increased both shoot and spur numbers in sweet cherries.…”

2. Materials and methods 2.1. Materials This study was carried out in Bafra in North Anatolia from 2015 to 2017. The altitude of the experimental area is 16 m. The area is located at the coordinates of 41°33′50″N, 35°52′17″E. The region has a mild climate. The hottest months are July and August and the coldest months are January and February (https://www.mgm.gov.tr/). The soil was a silty clay loam (33.73% clay, 55.35% silt, and 10.92% sand) with an oxidizable organic matter content of 2.71% (moderate). The pH was 8.03 (moderately alkaline reaction), the EC in soil was 0.55 dS

“…Summer notching did not increase branching. Greene and Autio (1994), Elfving and Visser (2007), Atay and Koyuncu (2013), andvon Bennewitz et al (2014) reported increased branching when late winter notching was used. The higher shoot numbers recorded in combined treatments with summer notching were a reaction to the preceding application of pinching or phytohormones.…”

“…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). Another mechanical method that occasionally can be used for prolepsis induction is the notching of one-year-old whips at the end of winter (Greene, Autio 1994;Elfving, Visser 2007;von Bennewitz et al 2014). This technique is nevertheless labour-demanding, extends the growing period in the nursery by one year, and may increase susceptibility to disease infections such as bacterial canker (Pseudomonas syringae) in some climates.…”

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.

The study was carried out in the spring of 2020 in the north of the country, variety Grace Star grafted on the rootstock Gisela 6, thin spindle crown shape. Planting distance 4.2x1.8 m. In spring 2021 was organized with the following gradation: 1. Trees trained after the thin spindle crown (control); 2. Solitary incision above the buds and processing the cut with water; 3. Solitary incision above the buds and treatment of the cut with growth regulator Progerbalin LG; 4. Circular incision at 25-30 cm distance on the axis with processing of the cut with Progerbalin LG growth regulator; 5. Extirpation removal of 4-5 axillary buds from top to bottom of the leader while keeping a bud intact. It was established that, to increase the branching potential of the tree axis when training intervened with solitary incisions above the buds and circular incisions at a distance of 25-30 cm on the axis with the processing of the cut with the growth regulator Progerbalin LG in the ratio one part of product to 8-10 parts of latex paint.
