摘要：

[Objective] The experiment aimed to provide technical guidance for cutting propagation of forage maize SAUMZI.[Method]The survival situation of cuttings at different stem parts and with different internodes numbers and nutrient basis of cutting growth were studied in this experiment.[Result]The survival of young cutting was high while the rooting rate,germination rate and soluble sugar content of lower part of old stem and young cutting were all high.The rooting rate and survival rate with two nodes were higher than those with one node.The total nitrogen content in young stem and in all stems of two-year-old strain were relatively high while soluble sugar content was positively correlated to germination rate,however,total nitrogen content did not show obvious correlation with rooting rate and germination rate.[Conclusion]The young cutting possessed the highest survival rate and germination rate.
