Figure 6From: A novel system for evaluating drought–cold tolerance of grapevines using chlorophyll fluorescence Correlation between electrolyte leakage and Fv/Fm under drought−cold stress (gradient cooling mode) in six different grape genotypes ( V. amurensis , ‘Muscat Hamburg’, ‘Centenial’, ‘Beta’, ‘Cardinal’ and ‘Zhi168’). The values were the mean±SE of results from three replicates.Back to article page
