摘  要：
通过扦插试验研究了由植物生长物质和树木菌根菌组成的复合制剂对108杨扦插苗成活率、苗高、地径、根茎 比、菌根侵染率、毛根数、生物量、树体电容、叶绿素含量以及抗病性相关酶活性等指标的影响。发现复合制剂可以 促进苗木的根系生长,苗木根系的毛根数、菌根侵染率及根茎比指标较对照有显著提高;可以促进苗木地上部分的 生长发育,成活率、苗高、地径、生物量、叶绿素含量、长势等指标较对照均有显著提高;可以提高苗木的抗病能力,苗 木的树皮相对膨胀度、过氧化物酶活性、多酚氧化酶活性及苯丙氨酸解氨酶活性较对照均有显著提高。经IBA溶液 浸泡处理亦可有效提高苗木的生长,但整体效果不及复合制剂的最佳处理。初步确定了复合制剂的最有效成分配 比及处理方法。

摘  要：
The authous studied the efttct of compound preparation made by ectomycorrhizal fungus and hormone on the growth and disease resistance of poplar cuttings. The results showed that the compound preparation could accelerate the growth of the poplar cuttings, because the amount of absorbing root, mycorrihizal infectin rate and ratio of root and stem were enhanced. Meanwhile, the compound preparation could accelerate the growth of the other part of the cuttings , because the cutting survival rate, height, diamete , biomass, content of chlorophyll and capacitance were increased. Finally, the compound preparation could enhance the disease resistance of poplar cuttings, because the RT, activity of POD and polyphenolase and PAL were increased. The IBA solution could also accelerate the growth of cuttings, but the effect was not as good as that of compound preparation.
