Abstract
The death rate of susceptible Japanese black pine was 91.1% after 3 months inoculated with Bursaphelenchus xylophilus.The death rate of second generation resistance Japanese red pine inoculated with different concentration was only 4.46%,no death for second generation resistance Japanese black pine. The results showed that resistance pine had high resistance to pine wood nematode,and resistance had no positive relevance with the inoculation number of pine wood nematode.The occurrence of cavitation had been seen in the pulp of the second generation resistance Japanese red pine inoculated,the cambia and the outer xylem had unaffected.The second generation resistance Japanese black pine had similarity with the second generation resistance Japanese red pine except that 2 tested pines had serious cavitation.There was the greatest number of pine wood nematode isolated from the second generation resistance pine after 1 week and the pine wood nematode could be isolated in the middle of pine stem.
