中文摘要:通过不同浓度外源精胺脉冲负压渗透处理的方法,研究了外源精胺在保持菜豆贮藏品质方面的作用。结果表明: 在温度(20±2)℃,相对湿度80%~85%贮藏条件下,经不同浓度(0、0.02、0.2、0.5、1.0mmol/L) 的外源精胺真空渗透处理后的菜豆,其贮藏品质均得到不同程度的保持。外源精胺不同处理可有效延缓菜豆腐烂和锈斑的发生,而且可以抑制菜豆失重率和豆荚切割力的增加,并使菜豆豆荚的可溶性固形物以及菜豆豆粒硬度和可溶性蛋白含量得以保持。不同浓度外源精胺处理效果比较表明,0.5mmol/L精胺处理保持菜豆贮藏品质的效果最好,贮藏至第8天菜豆腐烂指数和锈斑指数分别比对照低68%和23%。

Abstract:With the aim to investigate the influence of spermine (SPM) treatment by vacuum pulse infiltration on postharvest quality of common beans (Phaseolus vulgaris L.), common beans were immersed in SPM solutions (0, 0.02, 0.2, 0.5 or 1.0mmol/L) under vacuum (-20kPa) for 2min and then stored at 20℃, 80%~85% relative humidity for 8 days. The results indicated that exogenous SPM treatments could significantly inhibit water loss and cutting-force increasing, and reduce the rust spots forming and decay of bean pod. Exogenous SPM treatments could also remarkably prevent decrease in levels of the soluble protein in the bean seed and the total soluble solids in the bean pod. The treatment with 0.5mmol/L SPM was more effective than the other treatments. The decay or rust spots index of the bean pod treated with 0.5mmol/L SPM was about 68% or 23% lower than that of control in the 8th day of storage, respectively. The results could be applicable to improve quality of common bean for commercial purpose. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
