种子败育型葡萄胚珠中内源多胺含量与胚珠发育及败育的关系
Endogenous polyamines in stenospermocarpic grape ovules and their relationship with ovule development and abortion
摘要
Abstract
In order to clarify the relationship between endogenous polyamines and embryo abortion,the selfing fruits of stenospermocarpic grapes and seeded grapes were taken as materials,the polyamine content changes of ovules at different developmental stage after florescence were researched.The results showed that Pas content,Put content and Spd content were all increasing first and then decreasing,except the Spm content of seeded grape was always increasing.The PAs content,Put content and Spd content in seedless grape ovules were obviously lower than that of the seeded grape ovules.Spm content of seedless grape ovules at later developmental stage were lower,too.The ratio of（Spd＋Spm）/Put and Spm/Pas of Ruby Seedless displayed falling trend and that of Mars Seedless was rising first then falling,but that of seeded grapes was always increasing.Besides Put content,the other polyamine contents of V.vinifera had significantly positive correlation with ovule weight,while this correlation of hybrid of V.vinifera×V.labrusca was not significant except Spm contents.So the lower polyamine content and the sharply decreased polyamine content in seedless grape ovules might be the major factors that caused embryo abortion.关键词
