| 摘 要： | 燕麦是我国北方重要的粮饲兼用作物。低产是制约燕麦产业健康稳定发展的主要问题。本文从燕麦小穗多花多粒特性、小穗不孕性和抗倒伏性能等角度分析了燕麦产量形成的主要特征;并从产量构成因素、光合生产性能和源库关系等方面系统梳理和总结了燕麦产量形成的生理机制研究进展,比较了皮燕麦和裸燕麦产量形成的生理学差异,提出了提高燕麦产量的技术途径。

| Abstract: | Oat is an important grain and forage crop in Northern China. Lower grain yield is a main problem restricting the healthy and stable development of the oat industry. We analyzed the yield formation characteristics from the aspects of spikelet fertility, multiflorous characteristics, panicle infertility and lodging. We also summarized the physiological mechanism of oats yield formation from the yield components and photosynthetic production performance and source-sink relationship, and emphatically compared the differences of yield formation between the hulled and the naked oats. We proposed forward future research directions and emphases on oat yield improvement. |
