花后喷施外源物质对不同粒型品种子粒灌浆和蛋白质含量的影响

Effects of Spraying Exterior Substance After Florescence on Wheat Filling and the Protein Contents to Wheat Varieties with Different Grain Types

小麦不同粒型品种花后喷洒植物生长调节剂和N-P-K营养液后,籽粒中蛋白质的含量呈增加趋势,处理后,兰考8679处理的蛋白质含量在籽粒灌浆前期、中期、后期表现为高-低-高的变化趋势,而对照蛋白质含量在灌浆期表现比较平稳;温麦4号处理后籽粒蛋白质表现为前期高,中后期平稳,而对照表现为高-低-高的变化趋势。处理后粒重越高,这种趋势越明显。

The plant growth regulators and the total nutrient liquid were sprayed ＂after florescence in wheat varieties with different grain types, the protein in kernels contents were increasing. The kernels protein contents of Lankao 8679 wheat were high -low- high during the kernels filing stages, but the CK were steady. The kernels protein contents of Wenmai 4 wheat were high in early filing stage and steady in middle and last filing stage, but the CK were high - low - high. The heavier the kernel weight were, the clearer the tendency was.
