摘要 以C3盐生植物盐地碱蓬(Suaedasalsa)为材料研究了体内红色素的理化性质、随发育时期的变化及光照、温度、盐分对红色素积累的影响。结果表明:该红色素溶于水而不溶于有机溶剂,光抑制其积累,在酸性条件下稳定,为红色,在碱性条件下不稳定,为黄色,最大吸收峰为 538nm。根据这些特性,初步确定该类红色素为甜菜红素苷(betacyanin)。黑暗、低温、高盐环境有利于盐地碱蓬甜菜红素苷的积累,其中萌发期黑暗是诱导甜菜红素苷积累的重要因子。 Effects of temperature, light, salinity and developmental phases on the accumulation of red pigments in the C3 halophyte Suaeda salsa were studied, and the physical and chemical characteristics of the red pigments were also analyzed. The results indicate that: these red pigments are insoluble in organic solvents but free in water, the pigments are red-violet and stable under acidic condition while yellow and unstable under alkaline condition, and they absorb the highest value at wavelength near 538 nm, light suppresses their accumulation and enhances their decomposition. These results suggest that these red pigments are betacyanins. Darkness, low temperatures and high salinity enhance betacyanin accumulation in Suaeda salsa, and darkness in the germina- tion phase is one of the most important environmental factors for the betacyanin accumulation.
