Positions of the most relevant QTLs detected. a, Intrinsic elongation rate; b, slope of the response of elongation rate to meristem to air VPD; c, slope of the response of elongation rate to soil water potential; b₀ and c₀, x intercept of the same relationships (see Fig. 1B). QTLs of concentration of abscisic acid (ABA) in the xylem sap in plants grown at a predawn leaf water potential of −0.20 MPa. Only QTLs with highest F and high bootstrap values are presented, for better legibility (see Table II for other QTLs). QTLs that decrease the value of the trait in the PL F-2 are on the left side of the chromosomes and those that increase it are on the right.
