摘要:
为明确灰葡萄孢菌与蓝莓果实互作的发生规律,为蓝莓结构抗病育种及采后灰霉病的防治提供理论依据。在室温条件下将灰葡萄孢菌株接种于蓝莓果实表皮,每间隔0、8、16、24、32、40、48 h切取4 mm×4 mm大小表皮组织用于组织透明检视及扫描电镜(SEM)观察。结果表明,灰葡萄孢菌孢子接种于蓝莓果实8 h后,孢子开始萌发,蓝莓表皮细胞壁及气孔器结构完整;病菌接菌16 h,可见凸起的菌丝顶端侵入细胞壁;接种24 h灰葡萄孢菌孢子的侵染菌丝部分溶解,并与寄主表皮融合,侵染菌丝末端可见2个分支,并侵入蓝莓果皮细胞;接种32 h,灰葡萄孢菌菌丝末端可见绒毛状结构,并侵入蓝莓果皮细胞内部;接种40 h,灰葡萄孢菌侵染菌丝进一步向果皮细胞内扩展;接种48 h,灰葡萄孢菌菌丝已大量侵入蓝莓果实表皮。明确了在室温条件下病菌初侵染的时间以及主要侵入方式:即接种16 h,病菌即可侵入蓝莓果实表皮细胞,接菌40~48 h病菌即完成侵入并大量扩展、繁殖。病菌侵入方式主要以菌丝直接穿透寄主表皮为主,尚未发现病菌从气孔器侵入的证据。
