Abstract
Symptoms of pine needle rust diseases was observed was observed in field in northeast region of China and surface structure of aeciospores from pines was observed on the scanning electron microscope on. It was found that the different symptoms of pine needle rust disease are directly related to surface of aeciospores. The pine needle rust disease of Pinus-Haploxylon has one symptom type (exceptColeosporium pini-pumilae) and one aeciospore type. The pine needle rust disease of Pinus-Diploxylon has three symptom types and three aeciospore types.
