To evaluate the efficacy of the recombinant fowlpox virus vaccine against the heterotype IBV, the chickens were challenged with the homotype IBV LX4 strain and the heterotype IBV LTJ95I strain after three weeks post vaccination. Antibodies against IBV were detected in vaccinated chickens one week post inoculation. The CD4+ T-lymphocytes in the peripheral blood increased rapidly in all groups challenged with IBV, except for the vaccinated group challenged by heterotype strain and the low level of CD4+ T-lymphocytes remained until end of the experiment. In all the groups, a high level of CD8+ T-lymphocytes only was observed in the vaccinated group after challenging with IBVhomotype strain. The morbidity and the mortality of this group were 21.43 % and 0 %, respectively, which showed significant difference with other groups. In addition, the lesions of chickens and virus shedding were less in the vaccinated group challenged by IBV homotype strain comparing with other groups, but there was no difference for the average body weight of chickens in all groups.

Six bacteria and five mildews have been separated from 119 strains, wliich grew well on the culture media contained lignin. The result of taxonomic identification is that XI, X2 and X3 belong to Pseudomonas, X4 and X5 belong to Xanihomonas, X6 belongs to Mycoplana. A preliminary study has been carried out on the capacity of lignin degradation of the 6strains of bacteria, and strains X2 and X4 were chose to carry out the experiments. The most favorable temperature for the 2 strains is 30癈, and the pH is 7; After being treated by ultraviolet rays, activity of all the three kinds of lignin-degrading enzyme produced by the strains can be increased greatly, the bacteria increasing rate is remarkably improved.

The results showed that the sex ratio of trees was 1 m 2 f, and the natural T. cuspidata tree was able to sexually reproduce for many years. Male trees had fecundity when the diameter at breast height ranged from 1.5 cm to 92 cm, while female trees had fecundity when the DBH from 9.5 cm to 68.1 cm. Male trees typically flowered at the age about 20 years earlier than female trees. The numbers of microstrobili were 3 times more than that of megastrobili, and only 1/10 megastrobili developed into seed. The numbers of strobili and seed were correlated with DBH, crown diameter and height of trees; however, no significant correlations were observed with other site factors. Numbers of strobili decreased from the upper to lower canopy layers, while the quantity of seed decreased from the middle, upper to lower canopy layers. Seed-setting rate increased from the upper to lower canopy layers. Numbers of strobili and seeds in different directions of the canopy were not uniform, but the differences weren't significant.
