Silica content, leaf softness and digestibility in tall fescue (Festuca arundinacea Schreb.)

Abstract
In tall fescue breeding, a great deal of effort is devoted to develop soft-leaved varieties as it is generally accepted that leaf softness is positively correlated with digestibility and animal preference. In advanced breeding programs, it becomes difficult to discriminate the leaf softness between genotypes. Moreover, there is evidence that the digestibility of the softest varieties is not necessarily higher compared to varieties with coarser leaves. We studied the presence of trichomes (dentation) on the leaf margins and the silica content of plants in relation to the leaf softness and digestibility on a selection of 19 tall fescue clones. On average, soft genotypes had fewer trichomes (2.74 mm −1 ) on the leaf margins than coarse genotypes (9.03 mm −1 ), but there was no relation between leaf softness or trichome number and digestibility (R 2 = 0.05), nor between silica content and softness or digestibility (R 2 = 0.09).
