Feb. 1988, quasi-biennial and quasi-3-to-4-year oscillation are invenstigated. It is found that the two oscillations are propagating from west to east at all levels, being out of paase for the tropics but in phase for the mid-latitudes; for the latter oscillations in West Pacific, it travels equatorially from both mid-latitudes at low-levels while from south to north through a well-defined channel at...

结果发现：纬向风准两年、准3─4年振荡在热带地区上、下层均一致自西向东传播，但位相相反；在中纬度地区，纬向风准两年、准3─4年振荡上、下层均盛行自西向东传播，且位相一致；西太平洋地区低层纬向风准3─4年振荡均为从南、北半球中纬度地区向赤道传播；高层纬向风准3─4年振荡在175─140°W附近存在一明显的通道，且为自南向北传播，而且在经向上呈1波特征。

Lesion numbers on the inducer-treated plants treat with BTH, JZG and TS were significantly less than on control plants, in the meantime, treatment with BTH, JZG and TS led to an increase in activities of chitinase and β-1,3-glucanase in tobacco leaf tissue. Indicated these inducers triggered SAR in tobacco plants; in the same, BTH, JZG and TS were sprayed on the 1st leaf on melon plant before challenge inoculation with Erysiphe cidhoracerum.

发酵液、3—氨基丁酸(3-amin-butyric acid，3—ABA)和茉莉酸(Jasmonic acid，JA)等9种供试诱导剂在珊西烟上进行筛选：用各种诱导剂分别处理珊西烟从下数第6片真叶，上部第7、8、9叶挑战接种TMV，调查比较发病后枯斑数，筛选结果表明，只有经BTH、JZG和TS三种诱导剂处理的珊西烟叶片上的TMV枯斑数较对照显著减少，并能诱导珊西烟叶片中几丁质酶和β-1，3-葡聚糖酶活性增强。
