Results indicated that the variation was significant from treatment to treatment. S-deficiency caused bulging chloroplasts, loosening and dishevelled grana lamella, reducing organelle, and damaged chondriosome in mesophyll cells of the leaves, and empty cells of the roots, while S-excess, however, led to densification, condensation and randomization of grana lamella of the chloroplasts of the leaves, and separation of cytoplasms from walls of the cells of the roots.

结果表明，受S素营养胁迫的水稻，其根系及叶片的超微结构均发生了显著的变化：低S胁迫会造成水稻叶片叶肉细胞内的叶绿体结构肿胀，基粒片层松驰、散乱，细胞器减少，线粒体结构被破坏，根系细胞内几乎没有内含物；S浓度高则会使叶片叶绿体基粒片层致密、浓缩，无规则化，根系细胞发生质壁分离。
