【摘要】 利用透射电镜对经水杨酸(SA)和高温锻炼处理过的葡萄幼苗叶肉细胞进行了超微结构观察。观察到高温下,叶绿体与线粒体关系非常密切,线粒体数量较多,且常分布在叶绿体附近,二者靠的很紧,常常可以看到5~6个线粒体将叶绿体包围起来的现象。研究表明,葡萄叶肉细胞中线粒体和叶绿体在位置上的这种变化是对逆境的一种适应,是高温胁迫的结果。更多还原

【Abstract】 Observation on ultrastructure of mesophyll cell in young grape plants after heat acclimation and SA pretreatment under high temperature.It showed that there was a close correlation between chloroplast and mitochondria under high temperature.There were abundant mitochondrions,they often located near and enclose chloroplast.Especially,the phenomena of 5～6 mitochondrions surround chloroplast were often observed.The above changes are the result of the high temperature stress.更多还原
