Figure 4.
Overall representation of contrasting responses from Vigna unguiculata L. Walp cultivars, Aracê (yellow line), Novaera (dark blue line), Pajeú (dark red line), Pitiúba (red line), Tumucumaque (dark yellow line), TVU (blue line), and Xique-xique (green line), subject to different water levels treatments: 75 (A), 60 (B), and 45% (C) field capacity (FC). The data refer to relative alterations in the following parameters: shoot (SFM), root (RFM), and total fresh mass (TFM); shoot (SDM), root (RDM), and total dry mass (TDM); relative tolerance to drought (RToler); relative water content (RWC); membrane damage in leaf (MDleaf) and roots (MDroot); contents of chlorophyll a (Chla), b (Chlb), total (Chlt), and carotenoids (Carot); contents of soluble carbohydrates (SCleaf), free amino acids (AAleaf), and proline (Proleaf) in the leaves. The radar plot was designed using the data of TVU cultivar (blue line) as a reference.
