Abstract

The anti-mold effects of Phyllostachys pubescens extracted with solutions such as cold water , hot water , benzene +alcohol , benzene +ether , 10 g kg-1 HCl and 10 g kg-1 NaOH were studied .The results were as follows :(1)Bamboo specimens extracted with 10 gkg-1 HCl could successfully resist the testing molds including Trichoderma viride , Penicillium citrinum and Aspergillus niger .The average infection values of the treated specimens after a month were all zero .(2)Bamboo specimens extracted with 10 gkg-1 NaOH resisted Trichoderma viride and Penicillium citrinum better than Aispergillus niger .When the specimens were extracted only with 10 gkg-1 NaOH , the infection values were all zero .But when they were extracted with 10 gkg-1 NaOH and washed with water , the resistances to Trichoderma viride and Penicillium citrinum decreased dramatically , and the infection values being 1.58 and 0.35 respectively .Bamboo timbers treated with 10 g kg-1 NaOH had poor resistance to Aspergillus niger , and the infection values of the treated specimens before and after being washed with water were 1.82 and 2.79 respectively .(3)Bamboo timbers extracted with cold water , hot water , benzene +alcohol , benzene +ether were hardly effective to the testing mold .The infection values of the treated specimens were all over 3.00 . The different anti-mold effects were caused by different types and amounts of extractives .[ Ch , 3 fig .2 tab .12 ref .]
