Characterization of some Vitis vinifera L. Indigenous Varieties by Analysis of Leaf Photosynthetic Pigments

Chlorophyll content in leaves of 11 Vitis vinifera L. indigenous varieties (Iasi vineyard, Romania) was determined by two independent methods: spectrophotometry (extraction) and with a Opti-Sciences CCM-200 plus chlorophyll content meter (non-destructive method) with the aim of comparing the results. Also, this study was conducted to establish the values of chlorophyll a/ chlorophyll b and chlorophyll/carotenoid ratio in middle leaves of vine stocks, in the phenophase of progressive growing of shoots. Area and perimeter of leaves in this phenophase were determined. Total chlorophyll concentration in leaf extract varied from 0.67+ or -0.01 mg/g f.w. to 1.00+ or -0.03 mg/g g being highly correlated with the chlorophyll content index values (CCI) recorded by CCM-200 (R super(2)=0.9839; p
