摘要: 研究了热处理与间歇升温对菜豆冷害及其生理生化的影响,结果表明:间歇升温与热处理延缓了由于冷害引起的菜豆呼吸强度的上升、电导的增加和过氧化物酶活性的增强;降低了菜豆的表面水浸凹陷与锈斑的发生。两处理相结合具有协同增效作用,既能有效抑制表面水浸凹陷,又可阻止锈斑的发生,是防止菜豆冷害发生的有效措施。

Abstract:  Effects of heat treatment and intermittent warming treatment on the chilling injury and the physiological responses of kidney bean (Phaseolus Vulgaris L) were studied.The results showed that both treatments delayed the rise of respiratory rate,and postponed increase of relative electrical conductivity and peroxidase (POD) activity of kidney bean induced by chilling stress.The watery pitting and russet occurrence of kidney bean stored at the chilling temperature largely reduced by the treatments.The heat treatment and intermittent warming synergically reduced the watery pitting and russet occurrence of kidney bean stored at 2℃.The combination of the two treatments almost retarded the effects of chilling injury of kidney bean.It suggested that the synergism of two treatments was an effective method preventing the chilling injury of kidney bean.
