[Method] The laws of accumulation of starch in maize embryo and OSK(the other section of a kernel except embryo) of MEM(micro-endosperm maize) were studied in this experiment by taking Gaoyou 115 maize as control. [Result] The starch accumulation speed of MEM embryo was slightly lower than that of Gaoyou115 and the starch accumulation speed of MEM OSK was far lower than that of Gaoyou 115, so the starch content of the whole kernel of Gaoyou 115 was 3.4 to 4.5 times as high as that of MEM during harvesting. The embryo starch weight ration of Gaoyou 115 maize during harvesting was only 3% to 4% while that of MEM was 16% to 22%. Moreover, starch accumulation speeds of different MEM materials were different and there were significant differences in starch content during harvesting among different MEM materials. [Conclusion] The starch accumulation in MEM was slow, and MEM has widely variation on starch accumulation.展开更多

The results showed that there existed gradient differ- ences in pericarp tenderness among the 10 materials, of which PE10 had the best pericarp tenderness, T105 took medial place, and $33205 performed worst in peri- carp tenderness. Pericarp tenderness values of these 3 inbreeds increased curvedly from 12 to 24 days after pollination, in the spring （Wuhan, Hubei） and winter （Ling- shui, Hainan） of 2014. Moreover, the average pericarp tenderness at different time points presented the same decreasing order of $33205, T105, PE10, which was not altered by enviroment. With the growth of kernel, for one material, the difference of pericarp tenderness under different environments presented a law of increment, re- duction, uniformity. As for optimum-picking time, there was four days difference be- tween the spring in Wuhan and winter in Lingshui. However, there was no obvious difference in pericarp tenderness on the optimum picking time, which indicated that growing environment could affect the variation ratio of pericarp tenderness, but it still depended on the nature of materials.展开更多
