Fig. 2.24 Relationships (a) between percent stimulation of rhizosphere bacteria that can utilize phenolic acids as sole carbon sources and percent inhibition of absolute rates of leaf expansion of cucumber seedlings growing in CecU A soU treated with a 0.6 p.mol/g soil 4-equal-molar phenolic acid mixture (a = 0.50), where CPU equals colony-forming units and the 4-phenoUc...

Fig. 2.25 Effects of total phenolic acid composed of a 4-equal-molar mixture of p-coumaric acid, ferulic acid.p-hydroxybenzoic acid, and vanillic acid on absolute rates of leaf expansion (cm /day ...

Fig. 3.19 Effects of total phenoUc acid composed of a 4-equal-molar mixture of p-coumaric acid, ferulic acid,p-hydroxybenzoic add, and vanillic acid on absolute rates of leaf expansion (cm /day r = 0.44) of 12 day-old cucumber seedlings and microbial populations (CFU/g sod F = 0.49) that can utilize phenolic acids as a sole carbon source in Cedi A soil (a). Relationships between phenolic add-utilizing microbes (CPU, colony forming units) and percent inhibition of absolute rates of leaf expansion for cucumber seedlings are presented in (b). Values for (b) were calculated from (a). Figures based on regressions from Blum et al. (2000).

Fig. 2.6 Effects of ferulic acid and initial nutrient solution pH on net phosphorous uptake (a 22 day old r for pH 5.5 = 0.71, and pH 6.5 = 0.45), absolute growth rates of leaf expansion (b 16-18 day old r for pH 5.5 = 0.90, pH 6.25 = 0.69, and pH 7.0 = 0.72), and net water utilization (c 16-18 day old r for pH 5.5 = 0.95, for pH 6.25 = 0.88, and for pH 7.0 = 0.69) of cucumber seedlings. Figures based on regressions and data from Lehman and Blum (1999b) (a) and regressions from Blum et al. (1985b) (b, c).
