| Abstract: | This study revealed that an area meter with a semi-automaticfeeding mechanism underestimated the area of yellowish leavesand wavy leaves in crop plants. It is recommended that areameasurements should be made using photocopied leaves and leafsegments. The degree of underestimation should be checked whenchlorophyll meter (SPAD) values are less than 30.Copyright 1999Annals of Botany Company Glycine max Merr., Hordeum vulgare L., leaf area meter, leaf colour, Oryza sativa L.,Solanum tuberosum L., SPAD, Triticum aestivum L., Zea mays L. |
