“…Okinawa, mensurado pelo diâmetro do tronco, massa fresca e seca de ramos grossos e finos (Mayer & Pereira, 2006a.). Entretanto, dois anos após o transplantio para o campo, plantas de 'Aurora-1', enxertadas em 'Rigitano', não demonstraram vigor menor, bem como diferenças na brotação, na floração e no número de frutos por planta (Mayer et al, 2006b. ).…”

A pesquisa brasileira não havia desenvolvido, até o presente momento, um porta-enxerto clonal para a cultura do pessegueiro com características agronômicas desejáveis, especialmente com relação à resistência a nematóides-de-galha, facilidade de propagação por estacas herbáceas e indução à melhoria da qualidade dos frutos da cultivar-copa. O presente trabalho tem por objetivo apresentar a cultivar Rigitano de umezeiro, selecionada e aprovada para constituir um novo porta-enxerto para a cultura do pessegueiro. Identificada inicialmente como 'Clone 10', a cultivar Rigitano é resultante de um amplo projeto de pesquisa, realizado a partir de 1998 em colaboração com material procedente do Instituto Agronômico de Campinas (IAC), na Faculdade de Ciências Agrárias e Veterinárias (FCAV/UNESP), Câmpus de Jaboticabal (SP). Os trabalhos de seleção e multiplicação para validação técnico-científica final iniciaram-se com experimentos de propagação por estacas herbáceas, cujos resultados indicaram viabilidade do método nas quatro estações do ano, nas condições climáticas de Jaboticabal (SP). A enxertia com o pessegueiro 'Aurora-1', borbulhia em escudo ou escudo modificado, demonstrou ser viável em porta-enxertos de maior diâmetro (± 10 mm). Em condições de campo, 'Rigitano' revelou-se o menos vigoroso dos clones de umezeiro testados. Além disso, 'Rigitano' é resistente a Meloidogyne javanica e M. incognita, entretanto é suscetível a Mesocriconema xenoplax. Os resultados de campo, como porta-enxerto da cv. Aurora-1 de pessegueiro, revelam boa produtividade e frutos com boas qualidades pomológicas e tecnológicas. Os resultados de pesquisa obtidos revelam amplas possibilidades de sucesso da cv. Rigitano em sua validação como novo porta-enxerto de pessegueiro, bem como seu uso visando à redução do espaçamento de plantio e à produção de frutos de melhor qualidade.

“…The vigor of the rootstocks is a relative characteristic, because it depends, in addition to the genetic effects, on soil and climatic conditions, cultural treatments, fertilization (mainly nitrogen), spacing between trees, number of tested rootstocks and the genetic variability being evaluated in the trial, the reference rootstock and the scion/rootstock interaction (LAYNE, 1987;LORETI and MASSAI, 2002;MAYER et al, 2006;REIGHARD;LORETI, 2008;DAVIES Jr., 2017). Rootstock vigor can be assessed by trunk diameter, TCSA, tree height, canopy volume, fresh and dry pruning mass (DE ROSSI et al, 2004;REIGHARD and LORETI, 2008;BARRETO et al, 2017).…”

The clonal rootstocks allows preservation of mother tree genetic characteristics, such as vigor and produce a fasciculated root system, with an abundant thin roots. The objective of this research was to determine the effect of fifteen clonal genotypes as rootstocks on the agronomic performance of ‘BRS Kampai’ peach, as well as the technical feasibility of own-rooted trees (without rootstock) in a no-irrigated field condictions, in Pelotas-RS, Brazil. Bagged nursery trees were planted at the field in August, 2014, under a randomized block design with four replications of one tree per plot, and evaluations of trunk diameter, trunk cross-sectional area (TCSA), yield efficiency, annual and accumulated fruit yield per tree and per hectare were carried out until 2019. In the adopted experimental conditions, we conclude that ‘Barrier’ (P. persica x P. davidiana), ‘Cadaman’ (P. persica x P. davidiana), G x N.9 (P. persica x P. dulcis), ‘Ishtara’ [(P. cerasifera x P. salicina) x (P. cerasifera x P. persica)] and ‘Santa Rosa’ (P. salicina) do not have potential as a rootstock of ‘BRS Kampai’ peach due irregular bud breaking of scion, small fruits and/or low fruit yield. Clone 15 (P. mume) stands out for increasing fruit weight and maintaining satisfactory fruit yield per tree. ‘Flordaguard’ (P. persica) is the best rootstock tested, which is vigorous, do not present any undesirable agronomic characteristics and induce the highest yields per tree and per hectare, exceeding 50 t ha-1 in accumulated yield. Own-rooted trees of ‘BRS-Kampai’ peach have technical feasibility, as long as pruning is properly carried out.

“…On the other hand, 'Clone 15' is resistant to Meloidogyne javanica and M. incognita, ease of cloning ability by herbaceous cuttings, graft compatibility with peach cv. Aurora-1 and increased fruit size (Mayer et al, 2006). 'Tsukuba1' is tolerant to excess water in the soil and resistant to some nematode species (Picolotto et al, 2009;Souza et al, 2014).…”

Peach (Prunus persica L.) rootstock cultivars are typically selected for scion compatibility, ease of propagation, vigor, development, flowering season, yield, low need for cold temperatures, resistance to diseases, effects on the physical-chemical characteristics of the fruit, plant longevity and adaptation to adverse edaphoclimatic conditions. However, kinetic parameters related to nutrient uptake efficiency are usually not considered, such as those of nitrate (NO 3 −) and ammonium (NH 4 +). N is the nutrient that most impacts growth and yield. The objective of this study was to show the importance of the kinetic parameters of NO 3 − and NH 4 + uptake as additional criteria for selecting peach rootstocks. The experiment was conducted in a greenhouse. Three rootstock ('Aldrighi', 'Tsukuba1' and 'Clone 15′) were grown for 30 days in a pot containing 0.1 mol L-1 CaSO4 solution to reduce internal reserves of N. Afterwards, the plants were placed in Hoagland nutrient solution, where periodic collections of the nutrient solution were carried out for three days and the concentrations of NO 3 − and NH 4 + were determined. After the third day of collecting the solution, the plants were collected and then separated into leaves, roots and stems. Dry matter and total N content were assessed. The kinetic parameters related to NO 3 − and NH 4 + uptake (maximum uptake rate-V max , affinity constant-K m , Minimum concentration-C min , Influx-I) were calculated using Cinética software. The most efficient rootstock for NO 3 − and NH 4 + uptake was 'Tsukuba1', as it showed the lowest values of C min and K m and the highest values of V max and I max for NO 3 − and NH 4 +. NO 3 − uptake in 'Tsukuba1' and 'Aldrighi' showed a two-phase uptake pattern, suggesting the presence of low and high affinity transport systems. On the other hand, NH 4 + uptake in the three cultivars apparently followed a one-phase uptake pattern, suggesting the presence of a high affinity transport system. The kinetic parameters of NO 3 − and NH 4 + uptake are additional criteria that can be used in selecting peach rootstocks, as they directly influence shoot and root dry matter production and N accumulation in leaves.
