Leaf Area Determination in Grain Sorghum¹

Abstract

Synopsis Maximum length × maximum width × 0.747 was found to be an accurate and reliable method of estimating leaf area in 6 grain sorghum varieties. Using the component of variance technique, it was shown that most of the variability in area from leaf to leaf on the sorghum plants within a set of data was due to position on the plant.

Phylogenetic Relationships Among Teosinte, Maize and Its Hybrids

“…mexicana) and eight different maize genotypes (Zea mays L.) including three inbred lines, two single crosses, one three-way cross and two composite populations were used in this investigation ( Table 1) The morphological traits of the parents and their hybrids were measured on ten randomly selected plants in the field such as plant height (cm), number of basal tillers plant -1 , stem diameter (cm) at the third internodes above soil, length and width of the fourth basal leaf (cm), fourth leaf area (cm 2 ) estimated according to Stickler et al (1961), leafiness % = (leaf weight)/ (leaf + stem weights)*100 on dry basis estimated from a random sub-sample of stem, dry weight plant -1 (g) and crude protein (%) according to A.O.A.C. (1980).…”

RSSV 313: A Sweet Sorghum Donor for High Biomass

“…The mean SCMR reading was taken out in the end and presented at average SPAD value. The leaf area (dm 2 ) of the plant was calculated by taking maximum length and width at the broadest point of the green leaves and multiplying by the factor 0.747 (Stickler et al, 1961). Leaf area index (LAI) is the ratio of total leaf area per unit ground area or land area, both expressed in the same units.…”

“…The leaf area of plants was estimated by the relation of length, the largest leaf width and an adjustment factor equal 0.747 (STICKLER et al, 1961).…”
