【摘要】 江西板栗炭疽病菌 (Colletotrichumgloeosporioides (Penz)Sacc .)于初花末期开始侵染雌花柱头 ,侵染高峰在盛花初期。病菌经柱头侵入后 ,首先定殖于花柱 ,然后在花柱中潜伏或进一步蔓延至子房。病菌具有潜伏侵染现象 ,已展开叶片、托叶、枝梢皮层、花器 (雄花序、雄蕊、花柱 )、幼果、幼嫩总苞的针刺及坚果 (果皮和涩皮 )普遍潜伏带菌 ,以上结果系首次报道更多还原

【Abstract】 The pathogen (Colletotrichum gloeosporioides (Penz.) Sacc.) colonization in the styles started from the evening of early blossoming and reached the peak in the early full-blossoming. After colonization, it followed by ingression into ovary. Latent infection of pathogenic fungi exited widely in the outspread leaves, the cortex of twigs, flowers (including alabastras, styles), young fruit, the needles of young invoiucra and the capsules of seeds.更多还原
