چکیده انگلیسی
Polyploidy is common in many plant species. Up to date, few studies were reported on photosynthesis and leaf anatomy of tetraploid black locust (Robinia pseudoacacia L.), which has considerable value for agriculture and forest. This study compared photosynthesis and leaf ultrastructure on two black locusts. The values of Pn and Ci in tetraploid were significantly higher than those in the corresponding diploids. Significantly lower stomata dimensions (6.0 μm in length and 2.4 μm in width) and tomatal density were observed in 4Ã. Leaf trichome density was statistically different between 2à and 4Ã. However, no substantial difference in the ultrastructure of chloroplasts and mitochondria between diploid and tetraploid was observed under any stress. These ultrastructural characteristics may contribute to tetraploid a better protection mechanism than diploid.
