摘要:
 以24个西南桦无性系的组培苗为试验材料，对其叶绿素荧光特性进行研究。结果表明：无性系间叶绿素荧光参数Fo、Fv、Fm、Fv/Fo以及Fv/Fm均差异显著(p＜0.05)；FB4、BY-1无性系的Fv/Fo和Fv/Fm与A3及1-202无性系差异不显著，而显著高于绝大多数其他无性系，说明这些无性系光合效率高；无性系的苗高和地径均与Fo呈显著负相关，与Fv、Fm、Fv/Fo和Fv/Fm大多呈显著正相关；A3、FB4、1-202和BY-1等4个无性系生长表现好且光合效率高，可作为优良无性系在生产上推广应用。
Abstract:
 Chlorophyll fluorescence characteristics of the seedlings of 24 Betula alnoides clones were investigated.The results showed that chlorophyll fluorescence parameters including Fo,Fv,Fm,Fv/Fo and Fv/Fm were significantly different among these clones (p＜0.05).Fv/Fo,Fv/Fm of FB4 and BY-1 clones did not remarkably differ from those of A3,B3 and 1-202 (p＞0.05),while were quite higher than those of the majority of other clones,indicating that these clones were of high photosynthetic efficiency.The seedling height and root collar diameter were negatively correlated with Fo,while positively correlated with Fv,Fm,Fv/Fm and Fv/Fo.The above four clones were of good growth performance and high photosynthetic efficiency,and were therefore recommended as prior clones for application in practice.
