Abstract

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

摘要： 选取发育正常和败育一串红( Saliva splendens ) 5 个不同时期的胚胎, 分别提取、测定多胺( 精胺、亚精胺、腐胺与尸胺) 的含量变化。通过比较一串红胚胎发育不同阶段多胺物质的变化规律, 探讨多胺在一串红胚胎发育中的生理作用。结果表明, 一串红的胚胎败育和胚珠中较低的多胺含量及其在发育进程中较大的降幅有关; 在盛花期, 胚胎发育的关键时期, 正常胚珠中亚精胺的含量有一个明显的峰值, 而败育的胚珠中则无, 这表明亚精胺含量变化在胚胎发育中起关键调节作用。
