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

BENNEWITZ, E., FREDES, C., GUTIERREZ, L., LOSAK, T.: Eff ect of the co-application of Promalin® at different bud phenological stages and notching at diff erent distances on lateral branching of three sweet cherry cultivars (Prunus Avium L.) in central Chile. Acta univ. agric. et silvic. Mendel. Brun., 2010, LVIII, No. 2, pp. 45–50 A study was carried out during 2005 in the Maule Region of Chile (34.56°S, 71.5°W) to evaluate the effect of the co-application of Promalin® at diff erent bud phenological stages and notching at diff erent distances on lateral branching of three sweet cherry cultivars. Treatments signifi cantly increased total feather length in comparison to the untreated control only in the case of ‘Bing’. Total feather growth in these cases was more than double that of control trees. On ‘Lapins’ treated trees, total number of lateral shoots was in most cases signifi cantly increased. In ‘Stella’ trees, total feather length and total number of lateral shoots were not aff ected by treatments. cherry, branching agents, feather production, plant growth regulator
