Ultraweak luminescence generated by sweet potato and nonpathogenic Fusarium oxysporum interactions associated with a defense response was detected by a photoncounting method using ultrahigh-sensitive photodetectors. The time-dependent intensity variation, the spectrum and the two-dimensional imaging of the ultraweak luminescence are indicative of the defense response of the sweet potato to F. oxysporum. The production of ipomeamarone as a phytoalexin means that F. oxysporum induced the defense response in the sweet potato.
利用超高灵敏度光电探测器的光子计数法检测了甘薯与非致病性尖孢镰刀菌相互作用产生的与防御反应相关的超微弱发光。超微弱发光的强度随时间变化、光谱以及二维成像表明了甘薯对尖孢镰刀菌的防御反应。植保素甘薯黑疤霉酮的产生意味着尖孢镰刀菌诱导了甘薯的防御反应。
