Spring Tieguanyin tea tree pests have empoasca, tea leaf blight of aphids, and so on.

春季安溪鐵觀音茶樹主要病蟲害有茶小綠葉蟬、茶蚜蟲、葉枯病等。

The physiological and biochemical resistant mechanism of tea cultivars to tea brown blight caused by Guignardia camelliae. Making use of the mensuration of spectrophotometric analysis to study the enzyme activity of Peroxidas, Polyphenol Oxidas, Catalas, Phenylalamine Ammenia-lyase. The result showed that there was definite difference to the metabolic rule of defence enzymes activity in the annual leaf tissue of the resistant and susceptible cultivars after infecting.

The identification of tea plant resistance to tea brown blight The resistance of 13 tea plant cultivars to tea brown blight had the difference or remarkable difference. In general, the resistance of big leaf cultivars was relatively weaker, the resistance of middle leaf cultivars was relatively stronger.

茶樹品種抗云紋葉枯病的鑒定 13 個(gè)茶樹品種對(duì)茶云紋葉枯病的抗性存在顯著差異日本特级永久黄色网站?，一般大葉種材料的抗性較弱，中葉種材料的抗性較強(qiáng)。

Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1～5.9, the optimum pH for sporulation ranged 5.0～6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.

In the experiment, the tea plant shoots were cultured in vitro, and inoculated artificially. The result showed the disease condition in vitro was basically consistent with that of the tea plantation in nature. Therefore, we thought this identification method of tea plant resistance to tea brown blight was feasible, especially a large number of cultivars.
