ARAUJO, Eugênio Celso Emérito; SANTOS, Elizandra Paulino dos  and  PRADO, Carlos Henrique Britto de Assis. Leaf area estimation of mango (Mangifera indica L.) cvs Tommy Atkins and Haden, using linear dimensions. Rev. Bras. Frutic. [online]. 2005, vol.27, n.2, pp.308-309. ISSN 0100-2945.

Reports on leaf area estimation in mango is rare and with little convergent results. The objective of this work was to determine the equations that best describe the relationship among the linear dimensions (length and maximum width) and the leaf area (LA) of mango cvs Tommy Atkins and Haden, allowing the fast and non-destructive estimation of the leaf area just using the length (L), the maximum width (W), or both. The leaf area of mango can be obtained multiplying the product of the length for the width, and by the factor 0,74 (in Tommy Atkins cultivar) or by 0,78 (in Haden cultivar), as well as using the equations: LA = 4,96349 L - 33,429 (R2=0,86); LA = 17,02964 W - 18,88065 (R2=0,85) and LA = 0,73499 (LxW) + 0,59459 (R2=0,92) in Tommy Atkins cultivar or LA = 5,35282 L - 33,17061(R2=0,88); LA = 19,09951W - 24,61777(R2=0,89) and LA = 0,76015(LxW) + 0,43257(R2=0,99) in Haden cultivar.

Keywords : leaf length and width; non-destructive method.
