Abstract
The leaf mesophyll of Triticum and Aegilops is constructed from cells with one to ten arms. Volume of mesophyll cells per unit leaf area was larger in some monogenomic (A and B genome) plants than in polyploids, while leaf volume per unit leaf area was smaller in the former than in the latter. Consequently, the compactness of leaf blade is higher in these monogenomic plants than in the polyploids. D genome plants showed a much lower volume of both mesophyll cells and leaf blade per unit leaf area, but the compactness of the leaf blade was generally higher than in the polyploids. Mesophyll surface area per unit leaf area tended to be larger in the A and B genome than in the D genome and polyploid plants. Out of the polyploids, AB genome plants showed a larger mesophyll surface area per unit leaf area as compared with AG and ABD genome plants. Therefore, either the D or the G genome seems to have the effect of decreasing the mesophyll surface area per unit leaf area. A decrease of the compactness of leaf blade and the mesophyll surface area per unit leaf area in the polyploids was considered to be associated with the reduction of their physiological activities on the unit leaf area basis.
