Histological observations on grains of food crops and stems of vegetable and fiber crops applied by organic and inorganic (chemical) fertilizers

摘要

We investigated the effect of fertilizer type, organic (OF) and chemical (CF), on the histology of grains (rice, barley and soybean), vegetable (radish) and fiber crop (ramie). Each cross section was examined by optical, scanning electron and transmission electron microscopes. In both fresh (just after harvest) and samples stored long-term, some histological differences were observed between CF and OF products. Particularly with grains, gap (or separation) of cotyledon cells, obscure embryo sac liquid layer, thin seed coat or poor cell wall was observed in CF, but not in OF. Such a difference was more distinct in the grains stored long-term.
