The dynamic information of 331 animal genetic resources in 17 important animal genetic re-source provinces (regions) was analyzed. According to the population inbreeding coefficient, combiningwith the information of population dynamic change trend and cross degree, these genetic resources forthreatened degrees were classified. The results indicated that the population size of 138 breeds had in-creased, 147 breeds had decreased, 3 breeds were constant, 7 breeds (or varieties) were extinct, 9 breeds(or varieties) were critically endangered and needed urgently conserve, 50 breeds (or varieties) were endan-gered and should be conserved. We put forward a conservation and utilization plan for animal genetic re-sources.

在植物的抗光氧化过程中除了抗氧化酶起作用外,抗氧化剂也起着重要作用。在植物所有抗氧化剂中,抗坏血酸(AsA)和谷胱甘肽(GSH)最重要。外源水杨酸(SA)处理水曲柳(Fraxinusmanshurica)幼苗叶片,同时增加了AsA和脱氢抗坏血酸(DHA)的含量,使叶片中总抗坏血酸含量增加,这有利于水曲柳叶片抵抗光氧化胁迫。外源SA处理却使GSH含量降低,从而GSH在总谷胱甘肽中的比例降低。由于外源
