Increment of annual shoots and harvest in the top (over 2.2 m) was followed. Most commonly used practices, the June cut and tearing of young shoots resulted in the strongest growth in the top. The vigour of the top of the tree was the best reduced by the use of plant growth regulators (Regalis and NAA top coating) and replacing the top of the tree. The highest yield of the top of the tree was achieved by using Regalis, meanwhile tearing of the young shoots gave the lowest yield. The replacing the top of the tree is suitable measure for organic production, because it successfully reduces the vigour of the tree top without the use of growth regulators.</span></p>http://ojs.aas.bf.uni-lj.si/index.php/AAS/article/view/34malus pumilatree formcrownfloweringstemsplant anatomycrop yieldorganic agriculturebiological productiongrowth control
