在北农大高油(BHO)玉米群体的16个选择轮次中隔轮选取籽粒样品为试验材料,利用活体外人工瘤胃产气量方法,研究HOC籽粒含油量的选择进程对BHO群体籽粒的化学组成、活体外干物质和淀粉消化率以及瘤胃发酵参数的影响。BHO群体的籽粒含油量... 在北农大高油(BHO)玉米群体的16个选择轮次中隔轮选取籽粒样品为试验材料,利用活体外人工瘤胃产气量方法,研究HOC籽粒含油量的选择进程对BHO群体籽粒的化学组成、活体外干物质和淀粉消化率以及瘤胃发酵参数的影响。BHO群体的籽粒含油量从第2轮的6.84%提高至第16轮的13.20%,分别与籽粒淀粉和蛋白质含量呈现显著的负相关(r=-0.84,P<0.001)和正相关(r=0.74,P<0.001)。随着含油量选择进程的提高,HOC籽粒的活体外产气速度和淀粉消化率线性增加(P<0.001),这可能源于BHO群体的淀粉结构随含油量选择进程发生了改变。理论最大产气量和活体外干物质消化率随含油量选择轮次的提高而线性降低(P<0.001)。活体外发酵6 h的pH、总挥发酸(mmol/L)和丙酸比例(%)线性提高(P<0.001),乙酸和丁酸的比例线性下降(P<0.001)。活体外发酵24 h以后,不同选择轮次间的各项发酵参数均无显著差异。 展开更多

[Objective] This study aimed to investigate the effects of high-oil maize pollen on kernel traits of common maize, so as to provide some basis for the production and quality improvement of high-oil maize. [Method] Three hightoil maize varieties were cultivated to pollinate three common maize varieties. [Result] The kemel yield of common maize was increased or changed slightly, and the embryo weight was increased significantly after they were pollinated with the pollen of hightoil maize. The kemel embryo percentage and protein content of common maizethigh oil maize hybrids were higher than those of common maize inbreds. [Conclusion] The growth and development of kernel embryos, as well as the kernel quality of common maize was improved by pollination with hightoil maize. 展开更多
