赤桉组培苗和实生苗的早期生长对比表明,种内各基因型(生活型)间存在着较强的形态学上的差异,但是没有外表上的差异,无论是地上部分还是地下部分,都具有其微繁(组培苗)属性。9个月生的无性系林木较之实生苗林分稳定。实生林木和无性林木大都有发达的深生根和穿透粘重土壤的相同能力。然而,每种无性系群体都有一种特定属性,其根的分布集中在土壤(剖面)上部的20cm 优越的养分和水分条件下,9个月生的实生林和组培林的优势木高生长都超过2.5m,地上部分生物量大于500g 和发达根系长度超过8m。在盐渣饱和粘重的土壤条件下赤桉无性系在人工林中生长具有优势。
The comparison of the early growth of Eucalyptus urophylla between tissue culture seedlings and seedlings showed that there was a strong morphological difference among the genotypes (life forms) within the species, but there was no apparent difference. Whether aboveground or underground, Have their micro-propagation (tissue culture) properties. Clones of 9-month-old clones were more stable than the seedlings. Most of the live trees and vegetative forests have developed deep roots and the same ability to penetrate viscous soils. However, each clonal group has a specific attribute. Its root distribution is concentrated in 20 cm of superior nutrient and water conditions in the upper part of the soil (profile), and the dominant woody growth of 9-month-old seedlings All more than 2.5m, above-ground biomass more than 500g, and developed root length more than 8m. In the salt-saturated soil conditions sticky erythrocytic clonal growth in artificial plantation has an advantage.
