基质类囊体

具体反映在：（1）小麦叶绿体中除了比对照积累有较多的淀粉粒外，其基粒和基质类囊体膜发育较好；

The results were briefly summarized as follows : ( 1 ) The wheat leaves possessed normally developed chloroplasts with intact grana and stroma thylakoid membranes ;

幼叶细胞的叶绿体发育分化减慢、基质类囊体形成滞后、基粒数及基粒类囊体片层减少；

The deceleration of differentiation and growth of the chloroplast in young leaf cells , the retardation in forming thylakoid , the decrease of the grana numbers and thylakoid lamella ;

突变体叶绿素含量为野生型58%的黄绿植株与其突变亲本叶绿体超微结构无明显差异，基质类囊体与基粒类囊体高度分化，基粒数目以及基粒片层数目较多；

Yellowish-green plants whose chlorophyll content was 58 % of the wild type did not obviously differed in chloroplast ultra-structure from the parent , but their stroma-thylakoids and granum-thylakoids were highly differentiated and their granum and grana lamellae were relatively plentiful ;

超微结构观察表明，光合片层的减少或消失与降解及叶绿体分裂特别是不均等缢缩分裂而致基质组分和类囊体膜稀释有关。

This decrease or disappearance of photosynthetic lamellae is found to be correlated with the degradation of internal membranes , coupled With the diluting out of stroma constituents and thylakoid membranes due to chloroplast divisions , especially unequal constriction .
