对不同程度抗感赤霉病的４个冬小麦品种用禾谷镰孢ＦｕｓａｒｉｕｍｇｒａｍｉｎｅａｒｕｍＳｃｈｗ．ＪＦ－１２菌株的分生孢子悬浮液进行接种，并于接种后２～２２天测定寄主组织内抗坏血酸（Ａｓｃｏｒｂｉｃａｃｉｄ，ＡｓＡ）量、ＡｓＡ氧化酶及ＡｓＡ过氧化物酶的活性变化，同时观察ＡｓＡ对病菌孢子萌发和菌丝生长等的影响。结果表明，接种的感病或中感品种穗组织内较不接种的对照有明显的ＡｓＡ积累，ＡｓＡ氧化酶及ＡｓＡ过氧化物酶的活性较低，而抗病品种接种前后ＡｓＡ量无明显差异，ＡｓＡ氧化酶及ＡｓＡ过氧化物酶的活性较强。另外，适当浓度的ＡｓＡ对病菌分生孢子的萌发和芽管的伸长有一定的刺激作用，但对病菌菌丝的生长及病菌体内的ＡｓＡ水平无明显影响。作者对ＡｓＡ与小麦抗／感赤霉病性的关系进行了讨论，并认为ＡｓＡ与植物的感病性有关
Fusarium graminearum Fusarium graminearum Schw. The conidial suspension of JF-12 strain was inoculated and the amount of Ascorbic acid (AsA), AsA oxidase and AsA peroxidase in the host tissue were measured 2 to 22 days after inoculation, Bacterial spores germination and mycelium growth and other effects. The results showed that AsA accumulation and AsA oxidase activity and AsA peroxidase activity were lower in infected inoculated susceptible or susceptible cultivars than in non-inoculated controls, while there was no significant difference in AsA before and after inoculation , AsA oxidase and AsA peroxidase activity. In addition, the appropriate concentration of AsA on spores germ germination and elongation of the germ tube have a certain stimulating effect, but the growth of bacteria and pathogens AsA in vivo levels had no significant effect. The authors discussed the relationship between AsA and wheat resistance to SCF and concluded that AsA is associated with plant susceptibility
