- Abstract
Knowledge of the leaf area is critical to be important in several areas, especially in physiology, to evaluate the development of plants. The objective of this study was to evaluate different statistical models and identify what best fits leaf area yellow passion fruit (Passiflora edulis Sims. f. flavicarpa Degener) from linear measurements of the leaf. Were collected randomly 192 leaves from of 20 plants, and the measurements of length of the central lobe (LCL), the greater width of the central lobe (WCL), the greater width of the leaf (WF) and real leaf area (RLA), which is by means of digital images. Were evaluated the linear models, circumscribed, potential and exponential, using the RLAin function of LCL, WCL, WF, LCLxWCLand LCLxWCL. The most appropriate setting requires the use of LCL measures and WCL, and the equation is indicated is LA ?1.5885(LCLCxWCL).
