Abstract
This study examined the antagonism of Penicillium griseofulvum CF3 against four soil-borne fungal pathogens of potato,i.e.,Rhizoctonia solani,Fusarium solani,F.sulphureum,and Verticillium dahliae,and its growth-promoting and resistance-inducing effects on the plants.The mycelial growth rate of fungal pathogens and the growth of melon seed radicle and plumular axis were measured after treatment with sterile CF3 culture filtrate.The growth rate and stress resistance of potato plants associated with soil inoculation or seed coating with CF3 spore powder were tested via pot experiments.The results showed that the inhibition rate of sterile CF3 culture filtrate against mycelial growth of the four fungal pathogens and microsclerotia formation of R.solani were 53%-72.1% and 36.8%-100%,respectively.Pretreatment of melon seeds by soaking in CF3 culture filtrate significantly promoted the growth of radicle and plumular axis.Application of CF3 spore powder via soil inoculation or seed coating substantially promoted potato plant growth and enhanced the plant stress resistance.In particular,the fresh weight of aboveground parts and the polyphenol oxidase activity of potato plant associated with soil inoculation of CF3 spore powder were 38.3% and 9% higher than those in the control,respectively,whereas the corresponding malondialdehyde content was 28.8% lower than that in the control soil.In conclusion,P.griseofulvum CF3 has great potential for biocontrol of common soil-borne fungal diseases of potato and growth promotion of the plants.
