英国剑桥作物研究所的R.A.Bayles等于1982-1984年间,进行了16个冬小麦品种对于Septoria tritici(小麦叶斑病)自然感染的抗性差异显著性测定,他们用小麦叶斑病菌进行人工接种(共做29个处理)后发现,品种间的自然感染抗性呈正相关(r=0.56,P<0.05).供试小麦品种中,以Stetson和Aguila感病率最低(3.8%),Longbow最高(9.4%),一般在5-6-7%范围内.另将小麦叶斑病和S.nodorum(小麦颖斑枯病)的病原菌进行对比接种处理,发现品种对两种病的抗性并无相关性(r=0.28).
RABayles, of the Cambridge Crop Institute, UK, between 1982 and 1984 conducted a significant difference in the resistance of 16 winter wheat cultivars to natural infection with Septoria tritici (Wheat Leaf Spot), and they were inoculated artificially (R = 0.56, P <0.05) .There was the lowest prevalence of Stetson and Aguila (3.8%) and the highest of Longbow (9.4 %), Usually in the range of 5-6-7% .Other wheat leaf spot and S.nodorum (wheat spot blotch) pathogenic bacteria were vaccinated and found that the varieties of two kinds of disease resistance was not related Sex (r = 0.28).

在中国神话传说里，最富的神仙并非天上的玉皇大帝，而是海底的龙王，就连刚出道的齐天大圣孙悟空也明白其中道理，所以时不时敲诈一番邻居老龙王。 既然人类己有勇气探索火星，更不会放过家门口的未知地带。海洋面积有3.6亿平方千米，人类一直只能在浅海区活动和开发，对深海的情况几乎一无所知。到了近代，深海探测器技术突飞猛进，科学家也只探测了1%的海区，大部分海域还是等着认识的处女地。陆地资源大半已经用完，海洋
