The importance of rapid, nondestructive, and accurate measurements of leaf area (LA) in agronomic and physiological studies is well known, but a search of the literature revealed little information available for grape (Vitis vinifera L.). The results described herein include a comparison of 12 different mathematical models for estimating leaf area in 'Cencibel'. The simplest, most accurate regression equations were: LA 1 =0.587 LW (R 2 = 0.987) and LA 1 =0.588 LW (R 2 = 0.994), where LA, is leaf area measured using image analysis and LW is leaf length x maximum width. Use of maximum width (W), leaf length (L), petiole length (L p ), and dry weight of leaves (DML) as single variables in the regression equations were not as closely associated with total leaf area, although their R 2 values were also highly significant.

• Leaf area estimation by simple measurements and evaluation of leaf area prediction models in Cabernet-Sauvignon grapevine leaves (2008, background): “For all the models, highly significant linear functions were found between calculated and measured LA. Based on r2 and the mean square deviation (MSD), the model proposed for LA estimation in cv. Cencibel [LA = 0.587(L×W)] was the most appropriate.”
• Nondestructive leaf area estimation of ‘Niagara’ and ‘DeChaunac’ grapevines (2003, background): “In another study using V. vinifera, Montero et al. (2000) reported that linear (area ¼ 0:587WL, R2 ¼ 0:987) and power (area ¼ 0:647L1:956, R2 ¼ 0:968) models provided best estimates of ‘Cencibel’ leaf area.”

(Montero et al. 2000), 0.62 for soybean (Wiersma and Bailey 1975), and 0.73 for corn (McKee 1964).”
