Figure 2.

Frequency distributions of parameters of the response curves in the 100 studied RILs. A, Intrinsic LER (parameter a). B, Slope of the relationship between LER and meristem to air vapor pressure difference (parameter b). C, x Intercept of the same relationships (parameter b₀). D, Slope of the relationship between LER and predawn leaf water potential (parameter c). C, x Intercept of the same relationships (parameter c₀). The values corresponding to parental lines (PLs) are also shown. Insets in A, B, and D, Frequency distributions of r² corresponding to each RIL.
