对不同地区的19禾谷镰刀菌菌株进行培养性状比较试验,在PSA斜面上培养,菌株生长势无明显差异,基质色素可归纳为两类:一类为石竹紫,一类为苋菜红。浅盘培养各菌株有性子实体和分生孢子产生量差异明显,分生孢子产生量每克基质4.87万—441.54万个。25—30℃为禾谷镰刀菌生长最适温度,13.5—20℃生长缓慢,35℃以上明显受抑制。 Nineteen strains of Fusarium graminearum from different regions were tested for their traits. There was no significant difference in the growth of the strains when grown on the PSA slant. The matrix pigments were classified into two types: one is Dianthus caryophyllus and the other one is Amaranth. There was a significant difference in the amount of vegetative and conidial production of each strain cultivated in the tray, and the number of conidia produced was 48,700-44,154,000 per gram of substrate. 25-30 ℃ for F. thuringiensis growth optimum temperature, slow growth of 13.5-20 ℃, significantly inhibited above 35 ℃.
