Abstract/Contents:"The first objective of this investigation was to describe leaf blade stomatal-row patterns of 10 warm-season perennial turfgrasses, which represented samples from two subfamilies, four tribes, and nine species, and to determine the potential association between stomatal-row patterns and subfamily classification. A second objective was to provide a discussion of the literature concerning the association between whole-plant stomatal characteristics and water conservation. Three replicate turf plugs of each turfgrass were individually planted onto a fritted clay root zone contained in plastic pots and established for 9 months under glasshouse conditions. Descriptions of abaxial and adaxial stomatal-row patterns were made microscopically at X100 to 400 from polyvinyl leaf blade impressions. Newest, fully expanded leaf blades were used to make leaf blade impressions. Turfgrasses in the Panicoideae subfamily typically had three to four, ocasionally two, rows of stomata between any tow adjacent veins, depending on species and leaf blade surface. In contrast, turfgrasses in the Eragrostoideae subfamily consistently had two rows of stomata between adjacent veins on either surface of the leaf blade. These data suggest a relationship between stomatal-row patterns in Panicoideae and Eragrostoideae subfamilies of the major warm-season turfgrasses. Information in the literature does not support an association between turfgrass stomatal density and evapotranspiration (ET) rate under well-watered conditions. However, stomatal control of ET rate during a progressive drought may be an important water-conserving mechanism among turfgrasses. The literature is basically void of this information."
