ABSTRACT
Linear meassurements for non destructive estimation of leaf area in Chardonnay vines.

Angélica Gutiérrez T.1 y Arturo Lavín A.
 

The practical measurement of leaf area of vines (Vitis vinifera L.) under field conditions is necessary to establish its relation with growth and yield, especially in the evaluation of field experiments. At Cauquenes, Chile (35°57’ S, 72°19’ W), in the 1993/94 season, a trial was conducted to determine the variables that best estimated the foliage area of vine leaves. The products of multiplying maximum length x maximum width for the shoot leaves and length between leaf apex and petiolar point x width between points of the superior lobules for the leaves of lateral shoots yielded the best linear mathematical indicators.

Keywords: vine leaf area assessment non-destructive linear measurements, Chardonnay, Vitis vinifera.
