The G × E interactions were highly significant ( P ≤ 0.01) among the three seeding densities, suggesting the effect of seeding density on seedling traits should not be ignored (Table 1 ).

However, the quality of seedlings became worse with the increase of seeding density, and the seedling quality indexes such as dry matter of seedlings and root vigor showed a decreasing trend with the increase of seeding density [ 7 , 16 , 18 , 20 , 26 ].
