) endosperm development, the dynamic accumulation of the starch and the changes of cell active were observed by using I2-KI and TTC dyes, and the development of aleurone lay and endosperm transfer cells were studied by using resin embedding and cutting section, which combined optical microscopy with electron microscopy.

We collected maize caryopses of 8 d,10 d,15 d and 20 d after pollination and toke the wanted parts to observe the microstructure and the ultrastructure of endosperm transfer cells by using the methods of resin embedding and the technology of half-thinness(1 000 nm) and ultra-thinness(50~60 nm) slice cutting.

Relation between envelope and proliferation of amyloplast in endosperm cell of rice;

Study on diversity of endosperm cells in seeds of Leymus;

Characters of endosperm cells in the seeds of some species of Roegneria and their taxonomic significance;

The endosperm cells of 20 materials of Hystrix,Leymus,Psathyrostachys,Pseudoroegneria,Elymus and Lophopyrum in Triticeae were surveyed in this paper.

The effect of different fixation methods on the ultrastructural of endosperm cell in rice;

Endosperm represents a renewable,biodegradable source of materials,information from the study of endosperm could provide a basis for developing more efficient approaches for plant improvement and use.

Development of Wheat Endosperm and the Pathway of Nutrient Entering the Endosperm;

The effects of nitrogen on accumulation and translocation of temporary reserves in stem and leaf sheath and endosperm cell number and grain weight in wheat via Yangmai 158 were studied in 1995～1997.
