Abstract
Leaf area index of spur and minimal pruned vines was measured directly by destructive leaf sampling and indirectly from light transmission m easurements using the LAI-2000 and the DEMON instruments. Both instrum ents provided good estimates of plant and leaf area index. The LAI-200 0 had a tendency to underestimate leaf area index. The DEMON instrumen t provided the most accurate estimate of plant and leaf area index. Wi th both instruments it is important to validate indirect with direct e stimates of vine leaf area.
