The Influence of Rootstocks and Interstocks on the Nutrient Concentrations in ‘Valencia’ Orange Leaves (opens in a new tab)

JASHS 99(1):32–33; DOI 10.21273/JASHS.99.1.32. Table 1, p. 33 reports nutrient concentrations in Valencia scion leaves by rootstock (means of 10 determinations). Benecke is one rootstock treatment; this is not a measurement of Benecke leaves or fruit. Related 1974 California Agriculture report by the same authors may overlap and should not be counted as independent trial evidence.

Peer-reviewed article, Scientia Horticulturae 147:71–80; DOI 10.1016/j.scienta.2012.08.036. Full text consulted at https://swfrec.ifas.ufl.edu/hlb/database/pdf/00003019.pdf. Benecke results are from controlled greenhouse seedling graft-inoculation experiments, not field trials; interpretation is limited by irregular growth and leaf loss noted by the authors.

Influence of Rootstocks and Interstocks on the Macro- and Micro-nutrients in Valencia Orange Leaves (opens in a new tab)

California Agriculture 28(9):12–13. The supplied one-page PDF is printed p. 13, the end of this nutrient article above a separate bird-news item. The saved capture describes a Valencia scion nutrient study with Benecke among rootstock and interstock treatments; its authors/year/topic overlap the JASHS paper and should not be treated as independent trial evidence. See the cited paper/capture before using any specific direction of nutrient differences.
