摘　　要：果胶是一种广泛存在于植物细胞壁中的复杂胶体类物质,其主要成分是半乳糖醛酸,但对其具体结构尚不甚清楚,果胶的结构以及生理功能和对作物品质的影响是目前研究的热点之一。果胶在烟叶中约占其总质量的5%～13%,是影响烟叶外观等级和感官质量的重要因素。以往对该类较为复杂的细胞壁物质对烟叶质量的影响少有关注,近年来烟草行业对其影响逐渐重视,加大了对果胶的研究,并取得了一系列成果。综述了目前果胶对烟草的生理和品质性状影响以及调控措施,以期为提高烟草品质提供参考。Pectin is a widespread complex colloidal substance in the plant cell wall that the main ingredient is a galaeturonie acid, but its specific configuration is still unclear. The structure and physiological functions of pectin and its effects on crop quality are the hot topic in current research. Pectin accounts for about 5% -13% of the total mass in tobocco, which affects the level and sensory quality of tobacco leaf. In the past, little attention has been attached to impact on the quality of tobacco imposed by this kind comp？Lex cel~ wall material. In recent years, tobacco industry increases emphasis on the impact and research of pectin, thus making great achievements. This paper focused on the influence on the physiology and quality traits of tobacco imposed by the pectin, as well as control measures, so as to provide references to improve tobacco quality.
