| 摘 要： | 本研究测定了不同抗性的烟草品种接种赤星病菌后,苯丙氨酸解氨酶和过氧化物酶活性以及总酚和类黄酮含量的变化。结果表明,苯丙氨酸解氨酶活性峰与抗病性呈负相关,抗病品种的总酚和类黄酮含量高峰及过氧化物酶活性峰高于感病品种。这些峰值的大小可作为鉴定品种抗病性的生化指标。

| Abstract: | Tobacco varieties with different resistance after being inoculated with brown spotfungi Alternaria alternata (Fries) Kissler], their phenylalanine ammonia lgase (PAL)the activity of peroxidase (POD) the content changes of total phenols and flavoneidswere analysised. The results showed that PAL's active peak was negatively correlatedwith the disease resistance. The susceptible varieties' PAL active peak was 4. 3 timeshigher than that of the resistant varieties. The resistant varieties' POD active peak andthe contents of flavonoid and total phenols' values were higher than that of the susceptible varieties. These peak values can be used as one of physio-chemical evidence to evaluate the varieties disease resistances. |
