以根径15、25cm香樟假植苗为材料，研究不同剂量国光生根剂对2种香樟假植苗根系生长动态的影响。结果表明：经生根剂处理的2种规格香樟假植苗的生根数、总根系长度、平均根系直径等指标均明显高于清水处理。根径25cm香樟假植苗经生根剂处理的根系生长及各形态指标均高于根径15cm香樟假植苗经生根处理。初步确定国光生根剂1．0L处理根径15cm香樟假植苗与国光生根剂1．5L处理根径25cm香樟假植苗能用于刚移植苗木的生根处理，可提高生根数量。
以根徑15、25cm香樟假植苗為材料，研究不同劑量國光生根劑對2種香樟假植苗根繫生長動態的影響。結果錶明：經生根劑處理的2種規格香樟假植苗的生根數、總根繫長度、平均根繫直徑等指標均明顯高于清水處理。根徑25cm香樟假植苗經生根劑處理的根繫生長及各形態指標均高于根徑15cm香樟假植苗經生根處理。初步確定國光生根劑1．0L處理根徑15cm香樟假植苗與國光生根劑1．5L處理根徑25cm香樟假植苗能用于剛移植苗木的生根處理，可提高生根數量。

The influence of different doses of Guoguang rhizogenic agent on different dimeter-elass of Cinnamomum camphora （L.）Pres [ was studied based on the experiments which used the Cinnamomum Camphora （L.） Pres I of Ф15 cm and Ф25 cm. The main results were as follows：the morphology parameters of the transplanted Cinnamomum Camphora（L.） Pres I were root number,total root length and mean root diameter. The effect of rhizogenic agent on rooting of Cinnamomum Camphora（L.） Pres I was significant. Compared with CK （water） ,the influences of rhizogenic agent on Ф25 cm was bigger than that on Ф15 cm. Furthermore, 1.0 L Guoguang rhizogenic agent was selected for treatment of the Ф15 cm transplanted Cinnamomum camphora（L. ）Pres I , and 1.5 L Guoguang rhizogenic agent was selected for treatment of the Ф25 cm transplanted Cinnamomum Camphora（k） Pres I . They could accelerate the root survivor and growth as well.
