摘要
为了解锁阳(Cynomorium songaricum)寄生生长特性,使用物理方法和化学方法对其种子进行萌发诱导处理,观察萌发情况。结果表明:锁阳种子较小,成熟的种胚发育不完全,萌发前后处于球形原胚阶段。试验结果证明,锁阳种子萌发的启动,需有来自寄主根中的某种萌发刺激信号;外源赤霉素(GA3)及乙烯溶液对种子休眠的破除具有作用。
In order to understand the parasitic property of Cynomorium songaricum,the dormancy and germination properties of C.songaricum seeds are researched.The seed germination was promoted with both physical and chemical ways.The results show that the C.songaricum seeds are small,and the embryo of matured seeds develops incompletely and at the globular proembryo stage all the time before and after germination.The results testified that the germination of C.songaricum seeds need a certain stimulating signal form the host roots;exogenous GA3 and ethylene solution have a function of breaking the dormancy of C.songaricum seeds.
