Abstract: The appearance of variedness and biological characteristics of three variegated sport varieties and their mother
lant of Loropetalum chinense var. rubrum Mizhi Meihong were compared with virological identification, anatomy of
blade, content of pigments and photosynthetic traits. The leaf extracts from the plants were used to inoculate Glycine max
Cucumis satinus, apsicum annuum, Solanum lycopersicum L. chinense var. rubrum. The results showed that the
inoculated plants grew well, and did not exhibit any virus symptom. No viral granule was detected by TEM. The bud sport
varieties were able to maintain their Trait of variegated color by cutting propagation, and they had higher resistance to plunt
diseases and insect pests and were suitable to rowing in field in Ilunan Province. There was remarkable difference in
thickness of leaves, upper epidermis and lower epidermis among 4 plant specimens. The contents of carotenoid and
anthocyanin of variegated sport leaves were distinct dissimilar among 3 sport varieties, and the net photosynthetic rates

their mother plant. The varieties were elite germ plasm resouree for breeding of L. chinense var. rubrum. Especially, the
