Abstract: The change of polyamines content were examined from five different normal and abortion embryonic developmental stages. Through comparing the rule of the change of polyamine material at different embryo developmental stage , we investigated physiological functions of polyamines . The results showed that embryo abortion was related with less polyamine content in ovule , and its dramatically drop during development . In flourishing florescence which was key period of embryo development, spd content in normal ovule had a apparent peak amplitude , while this peak amplitude wasn′t appear in
abortion ovule , which indicated that spd played an important effect on embryo development .

Key words: Saliva splendens
