摘要
目的研究滇重楼种子在萌发过程中内源激素变化,为滇重楼种苗繁育提供理论依据。方法以室外与室内两种不同处理的滇重楼种子为材料,采用高效液相法测定滇重楼种子内源激素含量。结果经层积处理120d后,滇重楼种子开始萌发;整个萌发过程中,滇重楼种子内源激素GA显著升高,ABA显著降低,IAA含量变化不明显;室外处理的滇重楼种子萌发整体水平优于室内处理。结论在滇重楼种子育苗过程中,内源激素ABA和GA起着重要的作用。
Objective To study the change of endogenous hormone of the Paris polyphylla var in the course of seed germination and provide theory basis for seed breeding of Paris polyphylla. Methods After the seeds were treated by two different conditions including indoors and outdoors,the content of endogenous hormone（GA、IAA and ABA）was mensurated by RP-HPLC.Results After being treated for 120 days,the seed of Paris polyphylla var breed;During germination,the content of GA rose,the content of ABA reduced,the content of IAA remained;The germination level of the seed treated by outdoor conditions was higher than that of the seed treated by indoor conditions. Conclusion ABA and GA have a significant impact on the germination of Paris polyphylla var yunnanensis seeds.
