Abstract: -The objective of this work was to evaluate the effect of prohexadione calcium (P-Ca) and root pruning (RP) on the control of the vegetative growth and on fruit production and quality of 'Shinseiki' pear trees, under the climatic conditions of Southern Brazil. The experiment was conducted during the 2013/2014 and 2014/2015 crop seasons, in a 15-year-old orchard of 'Shinseiki' pear trees, trained to a central-leader system, with a 2x5 m spacing between plants, grafted onto Pyrus calleryana rootstock. The experi… Show more

“…When part of the root system is removed by root pruning, the plants are able to regenerate a new root system with a smaller size and more branches ( Wang et al 2014 ). This new root system provides an efficient intensive production system with reduced vegetative growth (by reducing the flow of nutrients, water and hormones from root to shoot), which led to the promotion of solar radiation interception, increased flower buds, more regular production ( Rademacher 2004 , Vercammen et al 2005 , Rodríguez-Gamir et al 2010 , Carra et al 2017 ), as well as the production of better quality fruit with smaller size, firmer fruit, more soluble solids content and less pre-harvest drop ( Schupp and Ferree 1987 , Ferree 1992 , Carra et al 2017 ). It has also been used by horticulturists to control plant size or vigor, as occurs in the production of bonsai plants.…”

“…It also facilitates the acquisition of nutrients with low mobility in the soil, such as phosphorus, an essential element for seedling growth (Azevedo et al, 2010). Finally, root pruning increases the total soluble solids content at harvest (Carra et al, 2017).…”

“…Alguns autores têm demonstrado que a poda do sistema radicular pode apresentar vários benefícios para o desenvolvimento das mudas (FREITAS et al, 2009;AZEVEDO et al, 2010;CARRA et al, 2017). Por outro lado, na literatura, há poucos relatos dos efeitos negativos da poda radicular sobre a formação e desenvolvimento das mudas em nível de viveiro (CASTRO FARIA et al, 2007).…”
