研究了6个新选甜玉米自交系及其15个F1组合在授粉后不同时间籽粒含糖量的遗传及变异规律。结果表明,授粉后不同时间籽粒含糖量有极显著差异,以授粉后20 d籽粒含糖量较高;要获得含糖量较高的甜玉米组合,需要选择双亲含糖量均表现优良的亲本材料进行组配,亲子遗传在不同组合中表现出明显差异。含糖量主要受加性基因效应的作用,非加性基因的作用相对很小,其遗传符合加性-显性模型。控制含糖量遗传的增效基因为隐性基因。

The heterogeneous mixed-grain microstructure is a common defect for the heavy forging of 316LN austenitie stainless steel. Isothermal compression experiments were performed on a Gleeble-3500 thermo-mechanical simulator to investigate the effect of process parameters on the fragment and re- finement of millimeter-grade coarse grains （MCGs） during hot cogging. The experimental results in- dicate that the stress of MCG specimens is much larger than that of fine grain （FG） ones at 1150 ℃, while the stress difference between MCG and FG samples became smaller at 1200 ℃. Moreover, the MCGs can be well fragmented and refined under the condition of temperature of 1200 ℃, strain rate of 0.01 s-1 , and reduction rate of 50%. Meanwhile, numerical simulations were conducted to study the influences of temperature, strain and strain rate on microstructure evolution. The results of ex- periments and simulations comprehensively demonstrate that the MCG results in the increase of de- formation resistance and incompatibility of deformation, and it can be fragmented and refined at 1200 ℃ so that the plastic deformation energy decreases remarkably with the increase of temperature from 1 150 to 1200 ℃.
