Abstract

Polyoxin B在200 ppm以上濃度，可抑制水稻稻熱病菌菌絲之生長，20 ppm以上則可抑制胞子之發茅。在15~60 ppm範圍內，對Alternaria級屬菌之胞子發茅及菌絲生長都不共有抑制之作用；惟不論在任何供試濃度下，對於稻熱病菌及Alternaria屬菌胞子之發茅管皆能引起球狀膨大之變異現象。在比較試驗之藥劑中，Kasumin對稻熱病菌菌絲生長之抑制情形與Polyoxin B相同，而對胞子發茅之抑制卻無多大作用；對於胞子發茅管亦不引起變異現象。其他如PMA, Granosan M在供試濃度下完全抑制供試菌之胞子發茅及菌絲生長；Arasan則可抑制胞子之發茅，但對菌絲之生長抑制，則因試驗之方法有所差異。而Suzu, Mertect及F1911則在供試濃度下（500, 1,000, 2,000 ppm一按成品稀釋），對胞子發茅及菌絲生長則均無顯著之抑制作用。由上述室內藥效檢定結果，吾人可推知Polyoxin對胞子發茅能引起發茅管呈球狀膨大之變異現象，以致對菌之侵入有顯著之阻礙作用，因之，預防的功效要比治療效果為佳。 The mycelial growth and spore germination of Pyricularia oryzae was inhibited Polyoxin B at concentratlons 200 ppm and 20 ppm, respectively. However, they were inhibited at concentratlons 15-60 ppm while Alternaria spp.were tested. The pronoumced morphorlogical effect on spore germination of P. oryzae and Alternaria spp. at tested concentrations was the formation of a bullbous germ tube. It was proposed that the formation of a bulbous germ the tube was inhibited to penetrate the host plant to achieve the protective effect against disease development. Among the other comparative tested chemicals. the inhibition of Kausmin on mycelial growth of P. Oryzae was similar with Polyoxili B, while it was no inhibition on spore germination. PMA and Granosan M completely inhibited the spore gormination and mycelial growth at tested concentratios of tested fungi. Arasan inhibited the spore germination and the inhibition of mycelial growth was changed depend on different methods tested. Suzu, Mertect and F1991 did not inhibit the mycelial growth and spore germination at concentrations on tested fungi.
