From: Experimental comparison of two methods to study barley responses to partial submergence
Effect of partial submergence with water or a 0.1% starch solution on chlorophyll content. SPAD values for leaf 1 were determined using a hand-held SPAD meter. Data on the left was obtained for plants subjected to partial submergence with water or control conditions. Three independent replicates were performed, with four plants per replicate for each condition. Data in the centre was obtained when partial submergence was applied using a 0.1% starch solution or under control conditions. Three independent replicates were performed, with the number of plants used per replicate varying between one and three. Data on the right represent SPAD values after partial submergence relative to the SPAD values obtained with control plants for a given variety. Mean values and standard error of the mean for the three replicates are shown. Statistical significance of the differences was determined using a Welch’s t-test because of unequal variance and sample sizes. Significant statistical differences are indicated with: ** for p-values \(<\) 0.01; * for p-value \(<\) 0.05
