Abstract
The objective of the study were to clarity the mechanism by Pestalotia theae incites the disease and the defense mechanism oh the pine seedling against the attack by the pathogen. The germination tube. 29 mm in diameter, produced by the germinating conidiospore penetrated the leaf cells via the stomata, which were wider in diameter. The pathogen was able to able to produce pectinolytic and cellulolytic enzymes required for the for host cell wall components. The epidermis was covered by a thick cuticulae layer. The activity of the peroxidise reduced the cotyledon, the primary leaf and the secondry leaf decreased, when the seedling were 1-2, 2-3 and >3 month old.
