C.nigrum<\/i> is a much-desired, multi-purpose tree species. Wood can be used for house construction, common furniture making and as plywood raw material. Prompted by this fact the research subject focuses on selection productivity for their germplasms and on propagation technique by grafting so as to obtain new generations of high and stable productivity. Fifteen plus trees of three provenances: Hoa Binh, Ninh Binh and Ha Tay have been obtained as the research result together with two grafting methods top wedge grafting and stem lateral grafting with survival rates of 25.8% and 30.8% respectively.<\/p>\n","protected":false},"excerpt":{"rendered":" Tr\u00e1m \u0111en (Canarium nigrum Engler) l\u00e0 c\u00e2y g\u1ed7 b\u1ea3n \u0111\u1ecba c\u00f3 chi\u1ec1u cao t\u1eeb 20 m -30 m, \u0111\u01b0\u1eddng k\u00ednh ngang ng\u1ef1c c\u00f3 th\u1ec3 \u0111\u1ea1t 50 cm \u2014 70 cm, th\u00e2n tr\u00f2n th\u1eb3ng, t\u00e1n l\u00e1 r\u1ed9ng v\u00e0 xanh quanh n\u0103m.
