球根花卉郁金香(Tulipa heterophylla )对菌根依赖性较大。为筛选促进该花卉生长的高效菌剂，作者于盆栽条件下试验了丛枝菌根(AM)真菌Acaulospora laevis (AC1)、Acaulospora appendicula (AC2)及Acaulospora laevis、Acaulospora appendicula 和Acaulospora colossica(AC3)的混合菌种对郁金香幼苗生长的影响。结果表明，接种 AM真菌的郁金香叶片数目、株高、地径、地上鲜物质质量、地上干物质质量、根平均直径、根系总体积、根系长度、叶表面积、超氧化物歧化酶、过氧化物酶、过氧化氢酶、叶片叶绿素 a、叶绿素 b和总叶绿素含量、叶片 N、P、K 含量高于对照，而丙二醛含量比对照降低，其中接种混合菌种处理与对照差异显著，各指标分别提高了90%、45%、85%、45%、38%、78%、19%、84%、71%、63%、67%、5%、18%、9%、46%、100%、15%，丙二醛比对照降低21%。结论认为供试的3种 AM真菌混合菌种促进郁金香幼苗生长的效应最大。
毬根花卉鬱金香(Tulipa heterophylla )對菌根依賴性較大。為篩選促進該花卉生長的高效菌劑，作者于盆栽條件下試驗瞭叢枝菌根(AM)真菌Acaulospora laevis (AC1)、Acaulospora appendicula (AC2)及Acaulospora laevis、Acaulospora appendicula 和Acaulospora colossica(AC3)的混閤菌種對鬱金香幼苗生長的影響。結果錶明，接種 AM真菌的鬱金香葉片數目、株高、地徑、地上鮮物質質量、地上榦物質質量、根平均直徑、根繫總體積、根繫長度、葉錶麵積、超氧化物歧化酶、過氧化物酶、過氧化氫酶、葉片葉綠素 a、葉綠素 b和總葉綠素含量、葉片 N、P、K 含量高于對照，而丙二醛含量比對照降低，其中接種混閤菌種處理與對照差異顯著，各指標分彆提高瞭90%、45%、85%、45%、38%、78%、19%、84%、71%、63%、67%、5%、18%、9%、46%、100%、15%，丙二醛比對照降低21%。結論認為供試的3種 AM真菌混閤菌種促進鬱金香幼苗生長的效應最大。

Tulipa heterophylla has great dependence on mycorrhizas.In order to select the efficient inocu-lants to promote the growth of the flower plants,the present author tested the effects of arbuscular my-corrhizal(AM)fungi Acaulospora laevis,Acaulospora appendicula and the mixed inocula with Acaulos-pora laevis,Acaulospora appendicula and Acaulospora colossicaon seedling growth of T.heterophylla under pot conditions.The results showed that leaf number,plant height,ground diameter,shoot fresh weight,shoot dry weight,root average diameter,total root volume,root length,leaf surface area,SOD, POD,CAT,chlorophyll a,chlorophyll b and total chlorophyll content,leaf N,P,K was higher than that of the control and the content of MDA was lower than that of control,the treatment with the mixed inocu-la showing the best effects,with increasing by 90%,45%,85%,45%,38%,78%,19%,84%,71%, 63%,67%,5%,18%,9%,46%,100%,15% respectively,and 21% for MDA lower than the control. It was concluded that the mixed inoclua with the 3 species of AM fungi gave the best benefits on seedling growth of T.heterophylla.
