Summary
Field and laboratory experiments were conducted during 1997/98 and 1998/99 in Zhejiang, China to estimate the leaf area of 2 lettuce cultivars, Erbaipi (long leaf type) and Yuanye (oval leaf type) using linear measurements. A total of 300 measurable leaves of different sizes , each from 30 randomly selected plants of both cultivars were sampled at different growth stages (8th, 16th, 20th and 24th week). Compared with other growth stages, sampling at the 16th week of growth was found to be the best for estimation of leaf area using regression equation for both cultivars. The leaf area estimations based on linear measurements in situ were found reliable. Regression models based on linear measurements can provide a rapid and convenient approach for the determination of leaf area in stem lettuce.
