This study compared the stomata frequency, stomata size, chlorophyll content and leaf characteristics (leaf length, width & leaf area) of 11 cultivars of walnuts. The stomata frequency, stomata size (stomata length and width) of all 11 cultivars were in the range 183-335 stomata/mm(2), 17.21-30.10 and 10.65-20.06 mu m, respectively. The stomatal frequency of Chandler was the largest and the stomata length and width of Fernor were the largest among all the walnuts cultivars. Chlorophyll and leaf characteristic were measured in same leaf, which were used for measured stomata frequency and size previously. The total chlorophyll and leaf area in all cultivars were in the range 0.34-2.37 mg/g and 26.77-86.92 cm(2). The largest chlorophyll content was measured in Pedro, while the largest leaf area was measured in Howard. Remarkable positive correlation was found among leaf characteristics and stomata frequency in walnut cultivars. (C) 2011 Friends Science Publishers
