- After the leaf senescence, chloroplasts became round and grana lamellae changed into disarray arrangement and blurring. 衰老后叶肉细胞叶绿体由长椭圆形趋于圆形,基粒片层逐渐变得杂乱至模糊不清。
- Results indicated that tabtoxin made the endomembrane system of the chloroplast be destroyed, the grana lamellae he disorganized and the chloroplast form vesicles. 结果表明:毒素导致叶绿体内膜系统破坏,基粒片层解体,叶绿体形成泡囊;
- The IUFA of grana lamella were significantly decreased, but the IUFA of stroma lamella were increased firstly and then decreased. 低温处理后,不饱和脂肪酸指数均比对照上升,但两优培九上升幅度没有汕优63大。
- At the time, in the their chloroplast grana, there are remarkable expansion and stroma thylakoid expanding are circular, the reduplication of grana lamellae are reduced obviously. 基粒和基质类囊体膨大,膨大的类囊体呈梭形或圆形,没有发现脂质小球的存在;基粒叠垛程度很低,平均每个基粒类囊体的片层数为5.;4。
- Stroma (pl. stromata) 1. The colorless ground matter between the grana lamellae in a CHLOROPLAST. It is the site of the dark (light-independent) reactions of photosynthesis. 基质:是叶绿体内的叶绿体基粒片层结构之间的无色透明物质。为光合作用暗反应(依赖光)的发生场所。
- The uniformity of chloroplast grana lamellae,, the numbers and cristae of mitochondria, and the concentration of nucleus karyolymph were different among different mature grade leaves. 不同成熟度叶片超微结构变化明显,主要表现在叶绿体片层结构整齐程度、线粒体个数和嵴数以及细胞核核液浓度上。
- Ultrastructural changes occurred in the chloroplasts in the yellow part including grana lamellae and grana decreasing and significant a ccumulation of starch grains and osmiophilic globules. 结果表明,在一定 条件下,叶片的失绿、复绿与叶绿素含量的下降、上升变化趋势一致;叶绿体结构在失绿区 表现为严重退化,基粒和基粒片层减少,淀粉粒和嗜锇粒增多;

- All the exsolution lamellae are brown spinel. 蚀变辉长岩中的斜方辉石已经完全蛇纹石化(保留了斜方辉石假象),斜长石完全被水钙铝榴石交代(保留斜长石假象),但单斜辉石保存完好,且发育由尖晶石叶片(棒)构成的出溶结构。
- The aging of chloroplasts was accelerated and the lamellae of the grana and stroma were disintegrated gradually under salt stress. 叶绿体是植物细胞中对盐分最敏感的细胞器[1],易受到盐胁迫的伤害,使其膜系统紊乱和破坏[2,3,4]。
- Having the form of a thin plate or lamella. 薄片形的有薄片或鳃瓣状形体的。
