GRAPEVINE LEAF DEVELOPMENT IN RELATIONSHIP TO POTASSIUM CONCENTRATION AND LEAF DRY WEIGHT AND DENSITY

Brian M. Freeman, W. M. Kliewer

Open publisher page 5 citations

Abstract

The plastochron index (PI) was developed for Vitis and related to lamina K + concentration. The concentration of lamina K + declined with increase in leaf age and PI, whereas total lamina K + content increased. Part of the decline in lamina K + concentration was attributed to an initial decrease in lamina density. Therefore, expression of K + concentration on a leaf area basis is recommended rather than on a dry weight basis.
