Productive and vegetative performance of peach trees grafted on six rootstocks in a replanting area

“…Remorini et al (2015 also reported differences among rootstocks in replanting areas, in which rootstocks that induced higher TCSA showed higher pruning mass. In 'Maciel' and 'Chimarrita', in most conditions assessed by Galarça et al (2013), 'Umezeiro' induced a lower pruning mass. However, Comiotto et al (2013), using the same combinations of scion/rootstock, did not observe any differences among rootstocks.…”

“…Comiotto et al (2013) found that 'Umezeiro' induced lower trunk diameter than 'Flordaguard' in 'Chimarrita', as well as lower trunk diameter than 'Okinawa' in 'Maciel'. Galarça et al (2013), using the same combinations but in different locations, stated that 'Umezeiro' showed lower trunk diameter than 'Flordaguard', 'Aldrighi', 'Capdeboscq', 'Okinawa', and 'Nemaguard'.…”

“…Picolotto et al (2009) reported an average yield of 11.1 Mg ha -1 for 'Chimarrita' on 'Capdeboscq' and of 11.86 Mg ha -1 on 'Okinawa'. According to Galarça et al (2013), yield varied from 1.1 to 17.7 Mg ha -1 for 'Chimarrita' and from 4.3 to 25.2 Mg ha -1 for 'Maciel', on different rootstocks and in different locations. However, these studies were not conducted in replanting areas, which may affect plant growth and result in lower yield, as pointed out by Rutto & Mizutani (2006).…”

Growth, yield and fruit quality of Chimarrita peach trees grafted on different rootstocks

“…Both Aldrighi and Capdeboscq are the most commonly used rootstocks in the south of Brazil since it is easy to get their stones from industries to grow seedlings (Rocha et al, 2007). However, other rootstocks such as Flordaguard, Nemaguard, Okinawa, Umezeiro, Tsukuba and Seleção Viamão have been used as alternatives in terms of fruit adaptation, productivity and quality (Comiotto et al, 2012(Comiotto et al, , 2013Galarça et al, 2013).…”

“…In general, several studies have shown that fruit plants may be influenced by rootstocks because they can affect plant vigor, growth and development besides productivity (Picolotto et al, 2009;Galarça et al, 2013) and fruit quality parameters, such as soluble solids, antioxidants, total phenols, ascorbic acid and flavonoids in the fruit pulp (Remorini et al, 2008;Orazen et al, 2011;Forcada et al, 2013). Therefore, studies on different rootstocks are needed to determine alternatives to replace the most commonly used ones in South Brazil, so that compatible and productive combinations can be established, fruit quality can be achieved and economic benefits can be assured to producers.…”
