5 lots<br /> of E. urophylla x E. pelita x E. grandis, E. urophylla x E. pelita x E. urophylla and one lot of E.<br /> pellita in Chieng Den - Son La city at the height of 790 m with sea level.<br /> The results after 39 months showed that of 10 lots, trees in 3 lots have met the target (over 20<br /> m3/ha/year), the trunk quality is the best or good: Uro in Ba Vi, 24xPG and 69xPG; 2 lots have<br /> reached expected development (15-20 m3/ha/year), best or good quality trunk is 24xPM and<br /> 24xPUX); rest 5 lots have reached medium expected development (9.1-11.6 m3/ha/year), the<br /> quality of trunk is quite good.<br /> Keywords: Eucalyptus seed, Son La province<br /> Ng ờ<br /> <br /> ẩ<br /> <br /> ị<br /> <br /> :<br /> <br /> .<br /> <br /> 5<br /> <br />
