| 摘 要： | 大豆孢囊线虫（SCN）是大豆生产上的毁灭性病害之一，土壤一经感染，则极难防治。利用植物本身的抗性，培育抗病品种是目前采用的最经济有效的控制措施。培育抗病品种首先要筛选和鉴定抗源材料。本研究采用抗感大豆孢囊线虫的野生、半野生、栽培大豆在接种和未接种大豆孢囊线虫3号生理小种条件下总酚含量动态变化以揭示其抗SCN3的生化机制。初步探讨了在SCN3侵染过程中，抗源生化指标总酚的表达情况，整个侵染期动态变化以及其与抗性关系，目的在于揭示抗源品种抗病的内在规律，从而为抗SCN3资源的筛选和鉴定及抗SCN3育种提供理论依据，为研究抗SCN3的遗传提供参考。试验结果表明，总酚可以作为鉴定SCN3生化指标之一。鉴别SCN3最佳时期为后期。

| Abstract: | SCN 3 is one of the most destruction diseases which is hard to cure when infected. Though effective, its price and pollution makes chemical medicine unusable. The most effective and economical way as to use the resistance inherent in the plant. The first step of cultivating resistant cultivar is the choosing and identifying resistant germplasm. Wild, semi-wild and cultivated resistant or susceptible to SCN 3 material is used in this study. Total phenolicis is measured to SCN 3 to determine the biochemical mechanism of SCN 3 resistance. The invasion process discussed. The aim is to disclose to internal regularity of cultivar resistance, so to lay academic foundation for choosing, identifying and cultivity SCN 3 resistant material. The results show,total phenolicis is one of identifying biochemical indexes. The best identifying period is the later period. |
