摘 要:
Compared with Pinus yunnanensis and P.armandii,P.squamata is similar to the former in terms of its eco-anatomic characteristics,such as the size of epidermis cells,the thickness of epidermis and the hypodermis.P.squamata may also be a kind of sun plants like P.yunnanensis.The density of mesophyll is between that of P.yunnanensis and that of P.armandii.The stomatal apparatus in P.squamata is the largest in size,while the stomata density in P.squamata is the lowest among the three pines.The size of stomatal apparatus and density of stomata in P.squamata may indicate its adaptation to more humid and cooler climate,implying that the present habitat may not be the most preferable environment for P.squamata.
