Correlation of <i>M</i>. <i>spicatum</i> and <i>E</i>. <i>nuttallii</i> RGR in the concurrent treatment.

Abstract

<p>Thin, solid line is 1:1 line. Most points fall to the upper left of this line, indicating a higher RGR for <i>M</i>. <i>spicatum</i> over <i>E</i>. <i>nuttallii</i>. The Pearson correlation coefficient (r) and p-values for each shade level are as follows (DF = 10 for all tests): zero: r = 0.54, p = 0.07; low: r = 0.80, p = 0.002; medium: r = 0.61, p = 0.04; high: r = 0.14, p = 0.68.</p
