Determining some ecophysiological traits of Protea ?Pink Ice? for the quantification of productive parameters

Enrique Misle

A study was carried out in a Protea ‘Pink Ice’ stand located in the coastal area of central Chile in an alfisol, aiming to determine some ecophysiological traits useful for the productive assessment of the crop, given the limited quantitative information of this variety. Floral stems were taken in four sampling dates measuring length and diameter, leaf area, specific leaf area, leaf area ratio as well as leaf mass and area of floral stems. The specific leaf area for this Protea variety was 44.8 cm2.g-1. Allometric functions were determined for the calculation of leaf area depending on leaf length and leaf number depending on stalk length. These results contribute to the quantitative crop assessment using fast and non-destructive estimation of some parameters.
