摘要:
对陕西省渭北和宝鸡地区花椒落叶病病情指数进行了调查,结果表明:常见花椒 品种的抗 病性序列为:米椒>豆椒>大红袍。对于同一花椒品种,在温暖高湿地区易感病,在海拔较 高且降 水量少的高山地区则发病较轻;花椒树冠下部感病指数高于树冠上部。对花椒落叶病病原 菌的生 物学特性研究表明:花椒盘二孢菌的生长最适温度为25℃,以燕麦片培养基生长状况最佳 ,碳源以 蔗糖最佳,氮源以蛋白胨为适宜;病菌菌落在偏酸性条件下生长良好;光照对其菌落生长 影响不大。
Abstract:
The investigation of defoliation disease indices of prickly ash in Weibei and Baoji areas of Shaanxi province showed that the resistance of different varieties (hosts) appeared in the order as follows:Mi>Dou >Daˉhongˉpao. For the same variety of prickly ash, the disease in dex in the warm and humid area was higher than cool and drought area in mountains of higher altitud e, and the lower part of the crown was easˉ ily infected than the top part. The tests on the biological charac teristics of pathogen,Marssonina zanthoxˉ yli , showed that the optimum temperature for pathogen growth was 2 5℃, with culture medium of oatmeal to be best,and sucrose to be the optimum medium from carbon so urce and peptone from nitrogen source. The pathogen favored growth condition with a little acid and lights h ad little effect on its development.
