From green part , transition color part to yellow part of variegated leaf from h . " so sweet " , the changing ultrastructure of chloroplasts is roundness from ellipse , granum - thylakoid swelling , vesicle bringing and osmiophile globule adding 在花叶玉簪品种h . ‘ sosweet ’叶片的叶绿体超微结构中，从绿色部分?过渡色部分?黄色部分出现由椭圆形转变为圆形、基粒类囊体肿胀、囊泡产生和噬饿颗粒增多的趋势。

Optical microscopy and electron microscopy were employed to study the microstructure and ultrastructure of the leaves of low temperature germplasm and measure or count the lengths of diachyma cells , number of diachyma cells per unit leaf area , chloroplast number per diachyma cell , the number of diachyma cell layers and the number of granum lamella of low - temperature wheat germplasm 应用光学显微镜和电子显微镜研究了小麦低温种质叶片显微和超微结构，测量统计了叶肉细胞长度、单位面积叶肉细胞数目、单个叶肉细胞中的叶绿体数目、叶肉细胞层数和叶绿体基粒片层数。

The results showed that low temperature wheat germplasm had many layers of small and closely - arranged diachyma cells , a large number of chloroplasts containing plentiful of granum lamella , and highly serried vascular bundles ; as it grew towards maturity , its structures such as diachyma cells , chloroplasts , and cells in the colored layers of seed ventral furrows aged slowly 结果表明，低温小麦种质较高温种质叶肉细胞小，排列紧密，叶肉细胞层数较多；叶绿体数量多，叶绿体基粒片层丰富；叶片维管束密集；随著生育期向成熟趋近，叶肉细胞、叶绿体、籽粒腹沟区有色层细胞等结构衰老缓慢。
