Variation of the activities of polyamine oxidase(abbreviated as PAO),peroxidase(abbreviated as POD),and the contents of soluble protein and lignin in the decotyledoned embryos were determined during in vitro culture.

The results indicated that the trends of protein accumulation of cotyledon and embryo of two types of kidney bean was basically identical after flowering,but their differences of change ranges were big,the accumulation amount of seed protein of trailing type was faster than that of erection type during seed early development stage (w.

The effects of TDZ,IAA,NAA and medium on bud initiation of cotyledon of immature embryo from jujube cultivar Jinsixiaozao were evaluated by L_9(34)orthogonal design.

The results were as follows: there were long and complicated morphological changes during the development of cotyledonary embryos;both the volume and color of cotyledonary embryos changed dramatically;the activity of SOD rapidly rose at the earlier stage of the development of cotyledonary embryos,then it gradually rose to a higher level.

Cloning and sequence analysis of the full-length cDNA of glyceral-dehyde-3-phosphate dehydrogenase gene from longan cotyledon embryo

In the present study, with the cotyledon embryos as plant materials, the cDNA-AFLP technology system was established and then used to investigate the differentially expressed genes concerning embryonic development of Longan, which aimed to lay the foundation for the research on Longan embryonic development.
