| 1 | Ecoregional variations of aboveground biomass and stand structure in evergreen broadleaved forests显示文摘Biotic and abiotic factors control aboveground biomass(AGB)and the structure of forest ecosystems.This study analyses the variation of AGB and stand structure of evergreen broadleaved forests among six ecoregions of Vietnam.A data set of 1731-ha plots from 52 locations in undisturbed old-growth forests was developed.The results indicate that basal area and AGB are closely correlated with annual precipitation,but not with annual temperature,evaporation or hours of sunshine.Basal area and AGB are positively correlated with trees>30 cm DBH.Most areas surveyed(52.6%)in these old-growth forests had AGB of 100–200 Mg ha^-1;5.2%had AGB of 400–500 Mg ha^-1,and 0.6%had AGB of>800 Mg ha^-1.Seventy percent of the areas surveyed had stand densities of 300–600 ind.ha^-1,and 64%had basal areas of 20–40 m^2 ha^-1.Precipitation is an important factor influencing the AGB of old-growth,evergreen broadleaved forests in Vietnam.Disturbances causing the loss of large-diameter trees(e.g.,>100 cm DBH)affects AGB but may not seriously affect stand density. | Tran Van Do Mamoru Yamamoto Osamu Kozan Vo Dai Hai Phung Dinh Trung Nguyen Toan Thang Lai Thanh Hai Vu Thanh Nam Trieu Thai Hung Hoang Van Thang Tran Duc Manh Cao Chi Khiem Vu Tien Lam Nguyen Quang Hung Tran Hoang Quy Pham Quang Tuyen Trinh Ngoc Bon Nguyen Thi Thu Phuong Ninh Viet Khuong Nguyen Van Tuan Dang Thi Hai Ha Tran Hai Long Dang Van Thuyet Dang Thinh Trieu Nguyen Van Thinh Tran Anh Hai Duong Quang Trung Nguyen Van Bich Dinh Hai Dang Pham Tien Dung Nguyen Huy Hoang Le Thi Hanh Phan Minh Quang Nguyen Thi Thuy Huong Hoang Thanh Son Nguyen Thanh Son Nguyen Thi Van Anh Nguyen Thi Hoai Anh Pham Dinh Sam Hoang Thi Nhung Hoang Van Thanh Nguyen Huu Thinh Tran Hong Van Ho Trung Luong Bui Kieu Hung | 2020 | Journal of Forestry Research2020，31，5： | 1 |

| 4 | Determination of the Administration Routes,Doses and Appropriate Age to Vaccinate With Ornitin Triple Vaccine For Cross-breed Colored Broilers in Vietnam显示文摘The study was to determine the appropriate dose and administration route of Ornitin Triple vaccine in cross-breed coloured broilers in Vietnam by evaluating the antibody titer against Ornithobacterium rhinotracheale(ORT)and local reactions at injection sites on chickens after vaccination.The study was divided into 2 trials.Both trials were designed with 3 vaccine dose groups:0.0ml(control group),0.25ml and 0.5ml and 2 different administration routes:subcutaneous at neck(SC)and intramuscular at breast(IM)injection.The result showed that,no statistically significant difference was found between antibody titer of two administration routes as well as 2 vaccine doses until 13-week-old.Local reactions at the injection sites of IM route was less severe than SC at neck and in higher dose would produce a more severe swelling reaction.Daily weight gain was found to have a slight decrease in the vaccinated groups within 2 weeks after vaccination,however,no statistically significant difference was found in later stage(P>0.05).In conclusion,Ornitin Triple can be used to vaccinate by IM with the dose of 0.25ml for coloured broilers at early age(3-week-old),or 0.5ml for older birds and should be careful for some reactions at the injection sites. | Nguyen Manh Ho Bui Ngoc Xuan Ha Le Thi Kim Tuyen Le Thi Anh Thu Le Thanh Hien Quach Tuyet Anh | 2019 | Veterinary Science Research2019，1，2： | 0 |
