Fig. 3From: Drought tolerance of the grapevine, Vitis champinii cv. Ramsey, is associated with higher photosynthesis and greater transcriptomic responsiveness of abscisic acid biosynthesis and signalingStem water potential of the four Vitis species depending on the RSWC. Relationship between the stem water potential and the RSWC in the four different genotypes grown in small pots. Red, green, blue and purple colors correspond to CS, RG, RM and SC, respectively. They are represented by 27, 52, 59 and 78 individual potted vines, respectively. Non-linear regression models were predicted for each genotype using an exponential equation (One-phase association) and the corresponding regression curves were drawnBack to article page
