Nutritional efficiency for nitrogen, phosphorus and potassium in peach rootstocks

Vegetative growth and foliar nutrient contents of peach on different clonal rootstocks

“…Despite the statistical differences for P absorption observed for the Sunraycer nectarine own-rooted and budded on 13 rootstocks, all concentrations of this nutrient were within the sufficiency range, being 1.57 g kg -1 for Santa Rosa and 2.50 g kg -1 for 'Okinawa' (Jimenes et al, 2018). Menegatti et al (2021) found no differences among the evaluated rootstocks regarding P absorption and transport efficiencies, but reported significant differences in the use efficiency of the nutrient for 'Capdeboscq' and Flordaguard.…”

“…As verified for P, rootstocks showed no statistical differences for K absorption and transport efficiencies. In another study, K use was more efficient for 'Capdeboscq' and Flordaguard than for Okinawa Roxo (Menegatti et al, 2021).…”

“…However, Jimenes et al (2018) found that the Sunraycer nectarine presented a N concentration within the sufficiency range when budded on 13 rootstocks, but a low one of 27.10 g kg -1 when own-rooted. Menegatti et al (2021) evaluated the 'Capdeboscq', Flordaguard, and Okinawa Roxo rootstocks for N absorption, transport, and use efficiencies, and concluded that the first two presented better results for transport and use efficiency. As observed for N, in the present study, the absorption of other nutrients, such as sulfur, Fe, and Mn, also did not differ significantly among rootstocks (Figure 5).…”

“…nucipersica), while Ishtara reduced this characteristic (Jimenes et al, 2020). Menegatti et al (2021) concluded that Flordaguard and 'Capdeboscq' were the best for macronutrient transport and use efficiency, but observed no differences among rootstocks for absorption efficiency.…”

“…It should be noted that distinct rootstocks may present different capabilities for controlling vigor and yield and for absorbing nutrients (Chatzissavvidis et al, 2008;Mayer et al, 2015;Mestre et al, 2015;Jimenes et al, 2018;Menegatti et al, 2021). In a study conducted with the 'Maciel' and 'Chimarrita' scions budded on the Aldrighi, 'Capdeboscq', Flordaguard, Nemaguard, 'Okinawa', and Japanese apricot (Prunus mume Sieb.…”
