“…When standardized by unit, the leaf tissue density and linear density of the leaf area were highly correlated with the NDF results; this finding is in accordance with the works of McClelland and Spielrein (1957), Prince (1961), andHerrero et al (2001), which state that NDF can be correlated to strength parameters and can be a good parameter for the selection of accessions. There is a clear possibility for correlating the NDF with the standardized parameters per unit of leaf tissue, shear strength by linear density and leaf area.…”

“…Accession BGP 123, belonging to P. atratum, which differed morphologically from the other accessions of this species when the shear strength values were recalculated by density per leaf area (Table 5), was again included in the P. atratum species. The patterns of the ste values can be explained by McClelland and Spielrein (1957) and Prince (1961), who stated that the intrinsic differences in length and weight of leaves between species could be explained by the expression of the shear strength measurements based on the density per leaf area (g cm -2 ).…”

The present study aimed to evaluate the application of shear strength and its correlations with leaf blade morphological and chemical variables as a tool capable of detecting differences between species and accessions of the genus Paspalum in the early stages of a forage plant breeding programme. A total of 13 Paspalum accessions from two species (Paspalum atratum and Paspalum regnellii) were subjected to analyses of shear strength, which also analysed the neutral detergent fibre, acid detergent fibre, lignin, and digestibility. Morphological measurements were also performed to standardize the shear strength per unit of leaf tissue. The experimental design consisted of complete randomized blocks, with four replications and eight cuts performed over 2 years. Shear strength was evaluated for its potential usefulness for detecting differences between accessions of the same species and the correlations of accessions. It was possible to use the shear strength measured with the texturometer to detect differences between species and accessions of the Paspalum genus. The results showed significant correlations of shear strength and neutral detergent fibre (r = 0.49), and negative correlations were found between digestibility and shear strength (r = -0.55). These correlations were maintained when the strength variables were standardized according to the morphological variables. Thus, shear strength can be used in the initial stages of the selection of species of the genus Paspalum.
