Abstract

Abstract: The objective of this work was to evaluate the effect of 19 clonal rootstocks on the vegetative growth and foliar nutrient contents of the 'BRS Kampai' and 'BRS Rubimel' peach (Prunus persica) trees. In the period of 2014 to 2018, two field trials were carried out in the municipalities of Jarinu and Jundiaí, in the state of São Paulo, Brazil. The BRS Kampai and BRS Rubimel cultivars, budded on 19 clonal rootstocks, besides their own-rooted scions, were evaluated in Jarinu and Jundiaí, respectively. In Jarinu, the Barrier, Cadaman, 'Capdeboscq', Flordaguard, GxN9, I-67-52-4, 'Okinawa', México Fila-1, Nemared, Tsukuba-2, and Tsukuba-3 rootstocks, as well as the own-rooted scion, showed the best performance for vegetative growth and foliar nutrient contents. In Jundiaí, all genotypes, except Marianna 2624 and Mirabolano 29C, did not show any statistical difference regarding vegetative growth. The performance of own-rooted 'BRS Kampai' and 'BRS Rubimel' is similar to that of traditional rootstocks, such as 'Okinawa'. Therefore, the evaluated scion cultivars may be an interesting alternative for sites with suitable biotic and abiotic soil conditions.

Highlights

Commercial orchards of stone fruits in Brazil are propagated by budding scion cultivars on rootstocks, which are often obtained from seeds (Mayer et al, 2014b; Souza et al, 2017)

Summary

Introduction

Commercial orchards of stone fruits in Brazil are propagated by budding scion cultivars on rootstocks, which are often obtained from seeds (Mayer et al, 2014b; Souza et al, 2017). Grafting or budding is used for many purposes, as for the maintenance of the genetic origin of the scion cultivar, homogeneity, vigor control, regulation of nutrient absorption, and early production (Chatzissavvidis et al, 2008; Mayer et al, 2013, 2014b). In Brazil, rootstocks from seeds are often used; they can have different cross rates and, present genetic diversity (Mayer et al, 2013, 2014b; Oliveira et al, 2018) This genetic diversity makes it difficult to maintain desirable characteristics, which may be obtained by first identifying scion cultivars of interest and cloning them by some propagation method, which requires evaluating their compatibility with rootstock cultivars (Barreto et al, 2017). Several propagation methods for Prunus spp. have been studied (Mayer et al, 2013), this technique is still rarely used in the country for the commercial production of peach
