摘要: 水杨酸是一种天然抑制剂,对植物有多种多样的作用,新近研究报道,它是乙烯生物合成的一种新的抑制剂。本文用水杨酸处理番茄、苹果、梨等果实,储藏在室温下,不时检查SA对果实贮存保鲜的影响。其结果表明SA处理的果实,PG活性比对照低,而硬度大,抗病力强。番茄,苹果和梨的无病好果率比对照果提高10%以上。上述结果证明,用SA处理绿熟番茄及梨和苹果,能有效保存果实新鲜,增强抗病力和延长货架的寿命。

Abstract: SA and sapirin (ASA) played a multiple role in plant functions. It has been reported in recent research that SA is a new inhibitor for ethylene biosynthesis. In this paper, tomato, apple and pear fruit were treated with SA, then stored at room temperature. The effect of SA on fruit preservation were examined during storage. The results showed that the PG activity of fruit was decreased by SA, and the firmness and resistance to diseases of the fruits were increased. The percentage of the healthy,disease free tomato,apple and pear fruits were increased by 10% than that of the control. Based on the above results,it showed that fruit treated with SA could preserve the fruit, improve the resistance to disceases and prolong it's shelf-life.
