Wampee( Clausena lansium )

a typical recalcitrant seed

was chosen as experimental material

and the protein synthesis in seed axes during development and under drying stress was labelled by 35 S Met. From the two dimentional electrophoresis maps of synthesized proteins

it was found that wampee seed axes had almost same kind of protein synthesis pattern through the whole development period except that a new 2 6×10 4 protein appeared at 63 days after flower

and the 2 6×10 4 protein was also induced by artificial drying stress at 53 and 63 days after flower.The stress responding ability of wampee to drying was weaker than orthodox seeds According to the results

the explanation of some specific physiology behavior of recalcitrant seed was made and another cause why recalcitrant seeds were desiccation sensitive was proposed
