从土壤和小麦根部分离到100多个草酸青霉菌,从中选出5个分离物,测定其对小麦苗的促生长作用.在温室进行4次试验.试验结果表明,在3次试验中,与对照相比,菌株Po-41处理组麦苗高,并有统计上的显著差异.Po-41处理还在一个实验中,表现为提高幼苗鲜重,在另一实验中,提高根鲜重,并均有显著性差异.在4个试验中,Po-41处理组的所用其他指标,也都表现比对照好,不过,没有显著性差异.Po-41发酵液中植物激素种类及含量测定表明,在酸性条件下,吲哚乙酸含量高.

More than 100 isolates of Penicillium oxalicum were isolated from soil and roots of wheat. Among them, 5 isolates were selected for testing the efficacy in promotion of growth of wheat seedlings. The testing was conducted in greenhouse for four times, i.e. four experiments. The data showed that the highness of wheat seedling responded to treatment of Po-41 in three experiments was higher than CK. Fresh weight of seedling and fresh weight of root responded to Po-41 were higher in one experiment separately comparing CK. All the difference mentioned above was significant based on statistic analysis. Responding to treatment with Po-41 in four experiments, all indexes seemed better comparing with that in non-treated CK, although it was not supported by statistic analysis. Analysis of phytohormones concentration in fermented solution of the isolate showed that IAA content was high in the acetic condition.
