摘要: 观测了藜科滨藜族(Atripliceae)、樟味藜族(Camphorosmeae)、碱蓬族(Suaedeae)和猪毛菜族(Salsoleae)30种C4植物的同化器官的解剖结构和δ13C值,共见到12种解剖结构类型。滨藜族包含2种类型,Atriplicoid-Ⅰ型和Atriplicoid-Ⅱ型,它们的差异仅在于结构中是否含有皮下组织。樟味藜族包括3种解剖结构类型,即含有皮下组织的Kochioid-Ⅰ型、叶肉细胞和维管束鞘细胞形成近似于环形的Kochioid-Ⅱ型和不含有皮下组织的Kochioid-Ⅲ型。碱蓬族包含3种类型,Kranz-Suaedoid-Ⅰ型和Kranz-Suaedoid-Ⅱ型结构中具有皮下组织,但是Kranz-Suaedoid-Ⅱ型结构中只具有一层叶肉细胞,这种结构存在于异子蓬属的异子蓬(Borszczowia aralocaspica),而Kranz-Suaedoid-Ⅲ型结构中不具有皮下组织。猪毛菜族植物叶片/同化枝的解剖结构类型有4种,它们的差异在于结构中是否含有皮下组织、次要的较小的维管束的位置以及环形的维管束鞘细胞是否被打断。30种植物的δ13C值范围-11.1‰~-14.5‰,显示为C4植物,与其同化器官解剖结构相对应。

Abstract: To examine the anatomical types of leaves and assimilating shoots in Chenopodiaceae and evaluate their carbon isotope fractionation values, a total of 30 species representing 4 tribes (Atripliceae, Camphorosmeae, Suaedeae and Salsoleae) in Xinjiang were examined using light microscopy and carbon 13C/12C isotope fractionation value. There are 12 leaf anatomical types. In tribe Atripliceae, it includes two leaf anatomical types, Atriplicoid-Ⅰ and Atriplicoid-Ⅱ. The only difference between these two types is the presence or absence of hypodermis. In tribe Camphorosmeae, there are three leaf anatomical types, including Kochioid-Ⅰ type with hypodermis, Kochioid-Ⅱ type with Kranz cells forming arcs or almost a ring, and Kochioid-Ⅲ type without hypodermis. In tribe Suaedeae, it includes three leaf anatomical types, Kranz-Suaedoid-Ⅰ and Kranz-Suaedoid-Ⅱ are with hypodermis. Borszczowia aralocaspica is of the Kranz-Suaedoid-Ⅱ type, with a distinctive one layer of mesophyll cells. Kranz-Suaedoid-Ⅲ type is without hypodermis. There are four anatomical types of leaves and assimilating shoots in Salsoleae. The differences between four leaf anatomical types in Salsoleae are the presence or absence of hypodermis, the position of small peripheral vascular bundles and complete or incomplete Kranz layer. The carbon isotope fractionation values for 30 species are ranged from -11.4‰ to -14.5‰, suggestive of a possible C4 pathway, which coincides with the leaf anatomical structures.
