叶片方位严重影响光合有效辐射(PAR)的吸收,因而也严重地影响光合作用。本文研讨了荒漠龙舌兰麻的叶片方位和辐射截获量。荒漠龙舌兰麻是生长在莫哈维和索诺拉沙漠地区,海拔1700米以下的砂质或多石土壤上的一种常见肉质植物。叶片丛生呈莲座状,其特征为:①刚直挺立;②不透明;③大致呈辐射对称;④能贮存水分;⑤具景天酸代谢(CAM)过程,在此代谢过程中,二氧
Leaf orientation seriously affects the absorption of photosynthetically active radiation (PAR) and thus also seriously affects photosynthesis. This paper discusses the leaf position and radiation interception rate of desert agave. Desert Tequila is a common succulent plant growing on sandy or stony soils below the sea level of 1,700 meters in the Mojaw and Sonora deserts. The leaf tufts are rosettes, characterized by: ① upright; ② opaque; ③ roughly radiating symmetry; ④ can store moisture; ⑤ with Sedum acid metabolism (CAM) process, in this metabolic process,
