LI Wei, SUN Zhong-Hai, ZHANG Wei-Cai and LIU Dao-Hong   

Abstract: Cold-resistance of citrus protoplasm and field plants in 5 different varieties was studied. The relative analysis between cold resistance of citrus protoplasts and that of field plants indicates that the cold resistance of citrus protoplasm can be considered as an index of cold resistance of field plants.

Key words: Citrus, Protoplast, Cold resistance index
