摘要(Abstract)：

为揭示微繁殖导致表观遗传变异的表现特点,以草莓品种佐贺清香和全明星为试材,研究了微繁殖导致草莓表观遗传变异的生物学性状表现和生理生化变化。草莓微繁殖原种苗和一代苗繁殖匍匐茎子苗的能力明显高于普通苗,其中佐贺清香微繁殖原种苗繁苗能力比普通苗高1倍以上。微繁殖苗后代与普通苗在物候期上没有明显差异,同样在叶片形态和发育上也没有明显差异。在果实成熟期,微繁殖苗后代的生长势强旺,佐贺清香二代苗和全明星二代苗分别比普通苗增产49.8%和9.7%;微繁殖苗后代叶片中可溶性糖含量、可溶性蛋白质含量、苯丙氨酸解氨酶活性、几丁质酶活性和β-1,3-葡聚糖酶活性明显低于普通苗,这意味着微繁殖可能导致草莓的抗病性降低。
