| Abstract: | A regional plantation experiment was carried out in Wugong County of Shaanxi on introducing twenty excellent Juglans nigra varieties into the field. By observing and analyzing their survival rates, keeping rates, stem diameters with side-branch growing within two years, their local growth characteristics were assessed. Preliminary conclusion is that variety No.19 is obviously best; No.4, 18 and 8 are relatively bad; cold-resistance of No.17 is worse than others; survival rate of No.13 is lowest; the other varieties are of no remarkable diffrence in growth. |
