Impact of LG and WU CIM on medium browning from immature embryo explants of diverse sorghum genotypes, following two weeks of culture on CIM. (a) Digital images were analyzed as described in the Materials and Methods and plotted as the mean area per petri plate (± SE) exhibiting medium browning. (b) Representative photos of petri plates for each genotype and protocol combination illustrating the levels of medium browning. Data shown in (a) were analyzed by one-way ANOVA, and tested for significance using Tukey’s HSD Post-hoc Test. For comparisons across genotypes for LG CIM, those with the same lowercase letter are not significantly different at p ≤ 0.05. For comparisons across genotypes for WU CIM, those with the same uppercase letter are not significantly different at p ≤ 0.05. For comparisons across the two media within a genotype, those with the same asterisk pattern are not significantly different at p ≤ 0.05.
