TAILIEUCHUNG - Dissertation summary: Study of biological characteristics and propagation techniques of the Phay’s seedlings (Duabanga grandiflora Roxb.Ex DC) in Bac Kan province

Research objectives: Supplement and complete a biodata and production technics of a native species with high economic values; the findings of the study are references for future researches, curriculums, technical officers, advisors and students; the study is also expected to build a technical guidance for producing Phay’s seedlings contributing to development andproduction of Phay, a native large-timber species, in Bac Kan province and other provinces with similar natural conditions. | MINISTRY OF EDUCATION AND TRAINING THAI NGUYEN UNIVERSITY LE SY HONG STUDY OF BIOLOGICAL CHARACTERISTICS AND PROPAGATION TECHNIQUES OF PHAY S SEEDLINGS Duabanga grandiflora Roxb. ex DC IN BAC KAN PROVINCE Speciality SILVICULTURE Study Code SUMMARY OF PHILOSOPHY DOCTORAL DISSERTATION IN FORESTRY Thai Nguyen - 2015 The dissertation has been completed at College of Agriculture and Forestry - Thai Nguyen University Scientific supervisors 1.

Necessary of the study The Circular 35 2010 MARD has introduced an additional list of forest trees which can be lucratively planted and produced in 63 poor districts of 21 provinces. This list included both timber and non-timber product species. Further the Resolution 30 A 2008 NQ-CP of Prime Minister has determined Phay Duabanga grandiflora DC as one of prioritized species which can be applied for both watersheds and production forests in Bac Kan province. However information depicting this species is limited and unavailable in national data systems of forest trees. Accordingly the Study of biological characteristics and propagation techniques of the Phay s seedlings Duabanga grandiflora DC in Bac Kan province is necessary since it is likely to contribute in development and production oflarge timber forests. 2. Purposes of the study . Contribute to national data systems of forest trees The study is expected to provide scientific data of the Phay Duabanga grandiflora DC species including the morphological physiological ecological silvicultural features and seedlings-producing techniques. . Contribute to .
