枣疯病是枣树的严重病害,在枣树、酸枣种植区经常发生。主要病症:花器返祖,产生小叶和黄化,芽萌发不正常,枝叶丛生,冬季小枝不易脱落。病症特别严重的小树当年即死亡,病症轻的小树一般1～2年,大树3～6年也会枯死。该病系由类菌原体病原引起。四环素、土霉素对枣疯病树有治疗作用。为了进一步研究类菌原体病原的性质,对枣疯病类菌原体进行抽提,用土霉素处理所得枣疯病类菌原体抽提物,并用电子显微镜观察对类菌原体粒子的影响。取具典型枣疯病症的病枣树及健康枣树叶片、
Jujube Bates is a serious disease jujube, jujube, jujube growing areas often occur. The main symptoms: flowers return ancestral, produce lobular and yellow, bud germination is not normal, branches and leaves, winter branch is not easy to fall off. Illness is particularly serious when the tree is dead, the disease is generally small tree 1 to 2 years, trees 3 to 6 years will die. The disease is caused by mycoplasma pathogens. Tetracycline, oxytetracycline on jujube tree has a therapeutic effect. In order to further study the nature of the pathogen of mycoplasma, jujube baker’s pathogen was extracted, and the extract of jujube baker’s disease was treated with oxytetracycline, and the mycoplasma particles influences. Take a typical date mad disease jujube and jujube leaves,
