“…This technique aims to reduce the vigor of plants, increase yield efficiency, and improve fruit quality. These effects have already been verified in several fruit species, such as peach (Rufato et al, 2006;Scarpare Filho et al, 2000;Telles, Biasi, Mindello Neto, & Peters, 2006;Tomaz, Schuch, Peil, & Timm, 2014), orange (Guilherme, Marinho, Biazatt, Campos, & Bremenkamp, 2014), pear (Baciu, Achim, & Cosmulescu, 2008), apple (Marcon Filho, Rufato, Rufato, Kretzschmar, & Zancan, 2009;Vaio, Cirillo, Buccheri, & Limongelli, 2009), cherry (Magyar & Hrotkó, 2008), and mango (Posada & Guzmán, 2009). Theoretically, rootstocks may indirectly affect fruit quality by several mechanisms, including budburst, time and abundance of scion flowering and flower quality (Daza, Galavis, Grande, & Santamaria, 2008).…”

Performance of interstocks in the plant development and fruit quality of plum trees

et al. 2019

The production of compact plants, which are slightly lacking in vigor and as productive as conventionally sized plants, is a trend in fruit growing. The objective of this study was to evaluate the vegetative performance and fruit quality of Gulfblaze and Reubennel plums intergrafted into two peach genotypes (UFV 186 and UFV 286). The experiment was arranged in a randomized block design using a 3x2 factorial arrangement (interstocks x cultivar) with four replications and one plant per plot. The non-intergrafted treatment was considered the control. Ten fruits were collected per plot for physical and chemical analyses. The evaluations were performed in the years 2014 and 2015. The interstock UFV 286 produced Gulfblaze trees with lower height in the two years of evaluation. When using the UFV 286 interstock, the trunk diameters were 50.2% smaller in Gulfblaze and 44.25% smaller in Reubennel than the control cultivars. Intergrafting had no influence on the fruit mass of Reubennel. In general, the peach genotypes UFV 186 and UFV 286 can be recommended as interstocks for reducing plant size in the plums studied. Intergrafting had no effect on fruit quality of Reubennel plums.

“…In this sense, the use of this method might be a suitable option for sites where the use of rootstocks does not present any clear advantage, such as nematode resistance (OLIVEIRA et al, 2003). A study of vegetative propagation of selfrooted Maciel plants through minicuttings in a semi-hydroponic system, concluded that this system improves the development of self-rooted peach seedlings (rooting > 90%) compared to propagation through minicuttings in plastic bags (TOMAZ, 2014). The cutting method combined with the semihydroponic system could, therefore, be an interesting alternative to seed propagation, because it provides better tree uniformity (excludes the possibility of genetic variability), reduces of the time needed for seedling production, and increases the possibility of producing well-nourished seedlings with strong root systems (TOMAZ, 2014).…”

“…An investigation by Tomaz (2014), which involved semi-hardwood cutting propagation in a semi-hydroponic system using sand as the substrate, demonstrated the favorability of a soilless technique. The resultant plants in this study were found to have average lengths that were three times longer than those from an independent study that was conducted during the same time frame, which involved a conventional system (CS), (PICOLOTTO et al, 2007).…”

Worldwide, peach propagation has been performed mainly by grafting scions of desirable cultivars on rootstocks obtained from seeds. There are, however, other potential propagation methods not widely adopted due to the limited reports on the field performance of the resultant trees. This study addressed this knowledge gap and investigated the field performance of peach trees of the cultivar Maciel that were established in an orchard (5.0 m × 1.4 m spacing) in 2011. The trees were trained in a "Y" system, with seedlings from three propagation techniques: 1) Conventional System (CS) -vegetative bud grafting of the scion on the rootstock of the Okinawa cultivar obtained from seed; 2) Rootstock by Minicutting (RM) -vegetative bud grafting of the scion on the rootstock of the Okinawa cultivar obtained by minicutting in a semi-hydroponic system; 3) Self-Rooting (SR) -self-rooting of the scion in a semihydroponic system. The vegetative, productive, and fruit quality parameters were assessed during 2012 and 2013. The Maciel peach trees that were propagated by the SR technique were found to have similar or even superior field performance to those propagated by the CS. The RM propagation method was also found to be an important potential alternative to peach propagation, since this it combines two techniques (cutting and grafting) to reduce tree vigor, especially if the goal is high-density planting.

ResumoEm todo o mundo, a propagação de pessegueiro tem sido realizada principalmente por enxertia de cultivares copa em porta-enxertos obtidos a partir de sementes. No entanto, existem outros métodos de propagação potenciais que não são amplamente adotados devido à pouca informação em relação ao desempenho a campo das plantas. A fim de responder a esta pergunta, em 2011, pessegueiros da cultivar Maciel foram plantados (5,0m ×

Selection of Peach Genotypes for Biochemical Fruit Quality Characterization

et al. 2017

-Peach is much appreciated by consumers and its popularity is mainly related with organoleptic characteristics. However, with emergence of concepts of functional foods (health promoters), there is high interest to study and to quantify the biochemical components of fruits. The aim of this work was to perform the biochemical characterization of peach genotypes, evaluating the genetic diversity and selecting those with desirable biochemical qualities for use as parents in future breeding programs. The experiment was carried out at the Laboratory of Plant Physiology -UTFPR -Campus of Dois Vizinhos, PR (Brazil), with fruits from 26 and 29 peach genotypes (Prunus persica) in the 2009/2010 and 2010/2011 crop years, respectively. The experimental design was entirely randomized, considering each genotype as treatment, using four replicates and four fruits per plot. Total and reducing sugars, total proteins, amino acids, total phenols, anthocyanins, flavonoids and phenylalanine ammonia-lyase enzyme activity (PAL) in fruits were evaluated. According to the results of two crop years, 'Cascata 967', 'Conserva 985', 'Kampai', 'Tropic Snow' and 'Cascata 1055' were selected as those with the highest levels of these compounds. Index terms: biochemical compounds, genetic divergence, Prunus persica. SELEÇÃO DE GENÓTIPOS DE PESSEGUEIRO QUANTO
