摘　　要：以杂种榕萍１号为父本，以榕萍１号原母本小叶满江红为母本进行回交，获得回交满江红３号（ＭＨ３－１），脂酶同功酶谱等鉴定为真杂种。其抗热能力和耐盐性均比父母本及其他满江红为高，品质好，繁殖速度快，适用于我国南方晚季和滨海盐土开发利用。回交满江红３号较其他萍种在细胞内超氧化物歧化酶和过氧化物酶均有大幅度提高，是回交满江红３号免受盐害的生理基础之一。By using hybrid azolla Rongping No. 1 as paternal,A. microphylla which was the maternal plant of Rongping No. 1 as maternal material for combination,a back-crossed hybrid azolla,MH 3-1 has been achieved.It was proved to be a real hybrid azolla by the identification of esterase zymogra-phy.Its heat-tolerant capacity is higher than paret plants and other tested azolla strains;the salt-toler-ant capacity showed the same tendency. Furthermore,it gets good quality,high multiplying speed,and suitable to be cultured in paddy field in late rice season,and utilized for the development of coastal saline soil.The analysed results showed that,MH 3-1 increased significantly the activities of its intra-cellular enzymes,including peroxidase and super-oxide dismutase to compare with other azolla strains,which is considered as the physiological basis of cell membrane to protect the back-crossed azolla from the harmness of salt stress.
