From: Developmental program impacts phenological plasticity of spring wheat under drought
The phenotypic plasticity was measured by the grain number in all charts. The Charts shows that environmental variance of GxE under drought stress was promoted by the adaptive developmental plasticity more than the stress duration only. A the developmental plasticity, in respect to the genetic and stress duration variances. An insignificant difference was found between the non-stressed plants and the plants that were exposed to drought stress during the tillering stage. B A significant reduction in grain number in response to any of drought stress durations of 7, 14 and 21 days. For A and B, the displayed letters; a, b and c indicate the significance (P < 0.05; one-way ANOVA and Tukey’s multiple comparisons tests). C The distribution of genotype variance in response to drought stress treatments, classified by alleles at the Rht loci. D Genotypes demonstrated dynamic responses to prolonged drought. Onas, Indian, Edmore, Klein Dragon and PWB343 had increased grain number for 21 days of drought while others had decreased grain number
