本试验以41个木麻黄种源为材料,对无性苗的高、地径生长进行测定。结果表明,不同种源无性苗的高、地径生长差异达显著水平;种源原产地的经度、纬度和海拔高度对无性苗高生长无显著影响。木麻黄的速生种源有E_7、E_(13)、E_(21)、E_(31)、E_(33)、E_(39)等6个种源。
In this experiment, 41 species of Casuarina equisetifolia were used as materials to determine the height and diameter growth of vegetative shoots. The results showed that the difference of height and diameter of asexual seedlings from different provenances reached significant level. The longitude, latitude and altitude of provenances did not significantly affect the height growth of asexual seedlings. The provenances of Casuarina equisetifolia were E7, E13, E21, E31, E33 and E39.
