Popis: Water stress brings about changes in growth and dry matter partition in peanut plants and the changes vary depending on peanut cultivars. The objectives of this study were to investigate the effect of 3 regimes of available soil water on leaf development and dry matter partitioning of 4 peanut cultivars. A 4×3 factorial experiment in randomized complete block design with four replications was used. Treatments were combinations of 4 peanut cultivars; Tainan 9, Khon Kaen 60-3, ICGV 98308 and ICGV 98324, and three soil water regimes; field capacity (FC; 20% soil moisture content), 1 2 available soil water ( 1 2 AW; 8.6% soil moisture content) and 1 4 available soil water ( 1 4 AW; 4.3% soil moisture content). On day 75 after seedlingemergence, depleting available soil water from FC to 1 4 AW significantly (p
