Vegetative propagation and planting techniques for Cinnamomum balansae H.Lec in Doan Hung, Phu Tho province

Abstract

The research aims at vegetative propagation of Cinnamomum balansae H.Lec by stem cutting method and planting trial 3 provenances of C.balansaecan species originated from Tuyen Quang, Ninh Binh and Phu Tho by strip plantation and on bare land in 2013. The result shows that: C.balansaecan get 33.7% growing adventitious roots without using growth stimulants. The average rate of growing roots for IBA stimulant is 60%, IAA is 53.3% and NAA is 51.7%. The concentration at which we get the highest rate of growing roots for IBA and NAA is 1.5%. Only for IAA, all 4 samples of concentration stimulate the same rate of growing roots after 40 days. After 3 years, C.balansae which planted by strip planting have higher D o and H vn than on bare land. By strip planting, C.balansae originated from Tuyen Quang provenance has largest with o D= 4.10cm, vn H= 3.43m; the ones from Ninh Binh provenance and Phu
Tho provenance have o D= 2.93cm, vn H = 2.15m. On bare land, C.balansae from Tuyen Quang also has largest with o D = 3.72cm, vn H = 3.09m; the one from Phu Tho has smallest with o D = 2.69cm, vn H= 2.1m. From this result, we can have initial assessment that C.balansae from Tuyen Quang has highest growth rate, following is Ninh Binh and Phu Tho provenances.
