Salt tolerance and regulation of Na⁺, K⁺, and proline contents in different wild turfgrasses under salt stress.

ABSTRACT: Turfgrasses show a wide range of salinity tolerance. In this study, twenty wild turfgrasses were collected from coastal regions in Japan, and their species; evolutionary lineage; salt tolerance levels; shoot and root K⁺, Na⁺, and proline contents; and amounts of ions secreted from their salt glands were determined. Among them, eighteen turfgrass species were determined based on the internal transcribed spacer 1 sequences. All collected wild turfgrasses were identified as halophytes and were divided into two salt-tolerant levels. They maintained the shoot relative water contents and suppressed excess Na⁺ accumulation in their shoots and roots and K⁺ content homeostasis compared with rice, resulting in the maintenance of a higher K⁺/Na
