Abstract/Contents:"Rates of water use, photosynthesis, leaf conductances, Leaf growth, and epidermal and stomatal characteristics were examined in Dactylis glomerata L. and D. marina Borrill. Maximum leaf conductances were negatively correlated with epidermal papilla cell height which was greatest in D. marina and least in glomerata. Apparently because of this relationship, marina was able to maintain leaf growth rates longer during a drying period than was glomerata. D. marina plants were more efficient water users than glomerata - growth rates of marina plants were greater for a given amount of water than were those of glomerata. Whole plant transpiration rates per unit leaf area were less in marina than in glomerata at any particular plant size. There were no significant differences in net CO2 uptake between glomerata and marina individual leaves. The implications of these relationships are discussed in relation to breeding for improved water-use efficiency."
