Garlic leaf area estimation using leaf blade dimensions and dry mass

The aim of this study was to estimate the leaf area of the garlic, based on leaf dimensions and leaf
dry mass. The leaf shape factor (f) and the dry mass factor (fb) were determined for cultivars Contestado 12, Caçador 40, Chonan Takashi, Jonas, Quitéria, Roxo Caxiense and Fuego Inta through the analysis of linear regression crossing the origin, through the leaf blade dimensions and leaf blade dry mass, respectively. The leaf blade dimension equations allowed lower estimate errors in relation to the leaf blade dry mass equations for all cultivars. The leaf area of all garlic cultivars can be estimated by a unique f equal to 0,59. It was determined an
fb equal to 150,86 for the group of cultivars Caçador 40, Jonas and Quitéria; 136,95 for the group of cultivars Contestado 12, Chonan Takashi and Roxo Caxiense; and 123,97 for the cultivar Fuego Inta.
