Figure 7From: Rapid determination of leaf area and plant height by using light curtain arrays in four species with contrasting shoot architectureCalculated plant pixel area (A) and calculated max height (base to the highest leaf tip; B) versus measured values in four species (maize, blue; barley, red; tomato, purple; rapeseed, green). Correlation coefficients for all species ranged between 0.9542 and 0.9925 (P < 0.0001). For maximum height a single regression model was highly significant (P < 0.0001). For leaf area the slope of a single regression model is significant for monocyledonous species (P < 0.0001) but not for dicotyledonous ones (P = 0.34). The dashed line depicts the 1:1 relationship. Measurements were conducted at a constant scanning speed of 0.9 m min−1.Back to article page
