In a test with ‘Bartlett’ and ‘d'Anjou’ pear on 8 Pyrus (P.) rootstocks, leaves of ‘Bartlett’ were high in S and Fe on ‘Bartlett’ seedlings (BS), in Zn on P. ussuriensis Maxim. seedlings (USS), and in B on seedlings of P. calleryana Decne (Cal). Leaves of ‘d'Anjou’ were high in P, Zn and B on BS, in N on USS, and in S on Cal. Both ‘Bartlett’ and ‘d'Anjou’ were high in K and Ca on P. betulaefolia Bunge seedlings (Bet). Fruit of both ‘Bartlett’ and ‘d'Anjou’ were high in N, K and Mg on Bet and Cal and high in Ca on Cal and USS. With both ‘Bartlett’ and ‘d'Anjou’, moderately high correlations were found between leaf and fruit concentrations of K and Mg; positive correlations were high for Ca and S with ‘Bartlett’ and for Zn and B with ‘d'Anjou’. There was a very high negative correlation between leaf and fruit Ca with ‘d'Anjou’.
