The genetic gains of superior families selected by progeny tests on early tree height, diameter breast-high and volume growth were 8.24%, 14.33% and 24.16% respectively.
And there are obvious difference of stemflow among different species, the main factors that affect the stemflow are crown structure, diameter breast-high and crown width.
