Out of 21 varieties investigated in 2 successive years, 2 had high contents of chlorophyll a + b (>0.38 g/msuperscript 2) in the leaves, while 9 had low contents (<0.34 g/msuperscript 2). The rest were intermediate. Significant positive correlations were found between chlorophyll content and N, P, K, Mn and Na contents (highest for N, with r = 0.799) and negative correlations with Fe, Zn, Ca and Mg (reaching r = -0.556 for Mg). The correlation with Cu content was nonsignificant, as were the correlations between leaf chlorophyll content and relative growth rate, leaf growth rate and net assimilation rate.
