Abstract/Contents:"Warm-season grasses had superior drought tolerance and post-drought recovery, compared to cool-season turfgrasses. In this study, seashore paspalum (Paspalum vaginatum cv. '2000') and Kentucky bluegrass (Poa pratensis cv. 'Excursion II') were chosen as research material. Leaf relative water content (RWC), water use efficiency (WUE), net photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (Tr), specific leaf area (SLA), osmotic adjustment (OA) and root length were measured to clarify the mechanisms of their differential drought tolerance. Seashore paspalum had superior drought tolerance as shown by higher RWC (11%), Pn (33%), Tr (52%), Gs (119%) and WUE (27%). Total root length in the 0-20 cm soil layer under Kentucky bluegrass was reduced significantly more after 20 d drought stress than under seashore paspalum, suggesting the former was less drought-tolerant. During post-drought recovery, seashore paspalum had higher RWC (9%), Tr (43%), Gs (154%) and WUE (34%), as well as lower SLA (8%) than Kentucky bluegrass. Further, total root length in the 0-20 cm soil layer showed the same changes as that during drought stress. The results indicated that lower water loss, higher water use efficiency and the fact that root growth in 0-20 cm soil layer was less reduced under drought, were the main reasons for the superior drought tolerance and post-drought recovery ability of seashore paspalum, compared to Kentucky bluegrass."
