PROMOTION OF INFECTION OF PLANT BELONGING TO GENUS EUCALYPTLIS WITH MYCORRHIZAL FUNGUS AND INFECTION PROMOTER

摘要

PROBLEM TO BE SOLVED: To promote the infection of a plant of the genus Eucalyptus with a mycorrhizal fungus useful for improving the growth of a plant of the genus Eucalyptus suitable as a pulp material, etc., by infecting a plant of the genus Eucalyptus with a mycorrhizal fungus in the presence of an extract of the root of the plant of the genus Eucalyptus with an aqueous organic solvent. ;SOLUTION: A plant of the genus Eucalyptus is infected with an ectotrophic mycorrhiza such as Pisolithus tinctrius, Scleroderma areolatum or S. citrinum as a mycorrhizal fungus in the presence of an infection promoter of a plant of the genus Eucalyptus with a mycorrhizal fungus comprising an extract of the root of the plant of the genus Eucalyptus with an aqueous organic solvent such as methanol, ethanol, propanol or butanol so that the period of the infection of the plant of the genus Eucalyptus with a mycorrhizal fungus is shortened, a infection ratio is improved and the infection of the plant of the genus Eucalyptus with a mycorrhizal fungus for improving growth of the plant of the genus Eucalyptus useful as a firewood, charcoal, a pulp material, etc., in soil deficient in phosphorus component is promoted.;COPYRIGHT: (C)1999,JPO
