本文报道不同播期和不同品种条件下特效烯对小麦的增粒增产效果。结果表明，孕穗前施用特效烯能显著增加穗粒数和产量。过早播种后期受冷害时，施用特效烯后相对增粒增产效应大；适时播种时，其绝对增粒增产效应大。特效烯对８０—８的增效大于绵阳１９。增粒乃特效烯提高了花粉可育率所致。多项式回归分析表明，花粉可育率对特效烯浓度和播期的反应是二元二次方程。
In this paper, we report the effects of different concentrations of different sowing date and sowing date on wheat grain yield. The results showed that the application of special effects of ethylene before booting significantly increased grains per spike and yield. Early premature chilling injury, the application of special ene after the relative increase grain yield effect; timely sowing, the absolute grain yield increase effect. Special effects ene 80-8 greater than the effectiveness of Mianyang 19. Enhancing grain is special effect alkene increases pollen fertility. Polynomial regression analysis showed that the response of pollen fertility to the concentration of EE and sowing date was a binary quadratic equation.
