Correlations coefficients (r) for six horticultural traits and nine phytochemicals, calculated using data standardized across trials.

<p>Correlation results include means from 23 cultivars, across eight pair combinations of location (Maine/Oregon), season (Fall/Spring) and management system (Conventional/Organic), 2006–2008^a.</p>a<p>For empty cells, r is not significantly different from zero (P<0.05).
