芝麻是重要的油料作物之一。但是,它的耐渍性弱,常因涝害影响产量,轻者减产,重者绝收。选育耐渍抗病芝麻品种和改善生态条件是提高产量的重要途径。前者已成为从事芝麻品种改良的主攻目标,而对后者的研究还比较缺乏。本项研究着眼于水渍对芝麻生长发育的影响,试图确立评价耐渍性的指标,为进一步聚类分析芝麻品种的耐渍等级奠定基础。选用芝麻品种豫芝一号。1989年6月初播 Sesame is one of the important oil crops. However, its resistance to flooding is weak, often due to waterlogging affecting the yield, the light yield reduction, heavy income. Breeding resistant streak resistant sesame varieties and improving ecological conditions are important ways to increase yield. The former has become the main target of sesame varieties to improve, and the latter is still relatively lack of research. This study focused on the impact of waterlogging on sesame growth and development, trying to establish indicators to evaluate the waterlogging resistance, which laid the foundation for further clustering analysis of sesame varieties. Selection of sesame varieties Yuzhi one. Early June 1989 broadcast
