摘要
结合生长情况和光合作用测定,通过生长指标和光合参数的分析,对2个白桦家系在烟台的适应性进行了评价,结果表明,在后期的生长中,黑龙江家系更能适应当地的自然环境条件,在白天能够正常生长,而陕西家系只能在早晨温度较低和光线较弱时,才能正常生长。通过光合作用测定,来分析不同家系的适应性和生长速率,对于林木引种驯化具有借鉴意义。
Combined with the growth and photosynthesis measurements,the adaptability of the two birch families in Yantai city of Shandong Province was evaluated through the analysis of growth indexes and photosynthetic parameters.The results showed that In the later stage of growth,the Heilongjiang family was more able to adapt to the local natural environment conditions and could grow normally during the day,while the Shaanxi family could only grow normally in the morning when the temperature was low and the light was weak.Through the measurement of photosynthesis,the adaptability and growth rate of different families were analyzed,which has reference significance for the introduction and domestication of forest trees.
