振动对小番茄生理特性的影响

在轻微机械振动处理下,研究了振动过程中振动工况对小番茄呼吸速率的影响及振动后各项生理指标变化.经试验发现,同一振动频率时,振动强度越大,圣女果小番茄的呼吸速率则越大.振动后,小番茄的呼吸速率、失重率和酸度明显高于对照水平;而果肉硬度则远低于对照水平.这表明在未造成果品机械损伤的条件下,机械振动仍然会对果品产生显著的影响,如促进果实的呼吸作用,加速果肉组织的软化,加速了果实的衰老进程,最终导致果品的品质、耐贮性的降低.

Effect of Vibration on the Physiological Characteristic of Cherry- tomatoes

Without any mechanical injury, respiratory rate of cherry-tomato rises with enlarged vibration intension at the same frequency. After vibration, respiratory rate, weight-loss rate and acidity were higher than those of the motionless ones. While rigidity of flesh was much lower. It was indicated that without mechanical injury, vibration could make obvious effects on fruits such as the acceleration of respiration and softening.
