Analysis on Laws of Accumulation of Protein in Micro-endosperm Maize Kernel

With the Gaoyou115 maize as contrast,the regularity of accumulation of protein in maize embryo and OSK(the other section of a kernel except embryo) of MEM(micro-endosperm maize) were studied in this paper.The results showed that the embryo protein weight per kernel of both corns increased straightly,the OSK protein weight per kernel of Gao you115 maize had not abated during the kernel developing,while that of MEM peaked on around 28 DAP(days after pollination) and there after declined.However,the OSK protein content of MEM increased obviously.The protein content of the whole kernel of MEM during harvesting was 20%,and it was about 2 times as high as that of Gaoyou115.
