Effectiveness of in vitro Mycorrhizal Inoculation of Tissue Cultured Eucalyptus grandis×E.urophylla in Field Trials

  • Received Date: 2001-12-01
  • In 1993 and 1994,two inoculation experiments of clonal Eucalyptus grandis×E.urophylla tissue culture plants,inoculated in total of 16 ectomycorrhizal fungi from Australia and China,in tissue culture containers,were established at Zhenhai State Forest Farm,Kaiping,Guangdong,China.After planting,tree height(H),diameter at ground level(D)and diameter at breast heigh(DBH)were measured at regular intervals.From 6 months after planting,all indices(H,D,DBH)showed significant growth increase due to inoculation(P =0.01 or P =0.05).Based on Duncan's Multiple Range Test (method),isolates E4070,H4509,E4240,H6177,H4339,E4726,C9301,C9213 and C9203 clearly improved tree height and diameter,indicating that these ectomycorrhizal fungi were effective on Eucallyptus grandis×E.urophylla trees.

Abstract: In 1993 and 1994,two inoculation experiments of clonal Eucalyptus grandis×E.urophylla tissue culture plants,inoculated in total of 16 ectomycorrhizal fungi from Australia and China,in tissue culture containers,were established at Zhenhai State Forest Farm,Kaiping,Guangdong,China.After planting,tree height(H),diameter at ground level(D)and diameter at breast heigh(DBH)were measured at regular intervals.From 6 months after planting,all indices(H,D,DBH)showed significant growth increase due to inoculation(P =0.01 or P =0.05).Based on Duncan's Multiple Range Test (method),isolates E4070,H4509,E4240,H6177,H4339,E4726,C9301,C9213 and C9203 clearly improved tree height and diameter,indicating that these ectomycorrhizal fungi were effective on Eucallyptus grandis×E.urophylla trees.
