摘要: 探讨NaCl、MnSO4、NaH2PO4叶面喷施对菠萝巴厘品种果实品质和抗逆性的影响。于花后20d和30d分别叶面喷施0.2% NaCl、0.2% MnSO4、0.2% NaH2PO4进行处理,并以清水为对照。结果表明,不同处理均增大了菠萝果实的单果质量(对照相比,MnSO4处理提高了18.83%,NaCl处理提高了15.37%,NaH2PO4处理提高了10.01%)。3个处理均提高了菠萝中可溶性固形物和VC含量,MnSO4处理提高的幅度最大。MnSO4处理降低了可滴定酸含量,但对总糖的含量没有影响,同时提高了SOD和POD活性。总体看来,MnSO4和NaH2PO4处理对菠萝果实的品质发育有一定的促进作用,MnSO4处理优于NaH2PO4处理。

Abstract: NaCl, MnSO4 and NaH2PO4 were respectively sprayed on the leaves of pineapple (Bali variety) 20 and 30 days after anthesis in order to investigate the effects of these chemicals on the quality and stress resistance of pineapple fruits. The results showed that spraying of NaCl, MnSO4 and NaH2PO4 increased the single-fruit weight by 15.37%, 18.83% and 10.01%, respectively. All these treatments could increase the content of total soluble solid (TSS) and vitamin C, and MnSO4 treatment was the best, which decreased titratable acid content and increased superoxide dismutase (SOD) and peroxidase (POD) activities, but had no effect on total surge content. In collusion, MnSO4 and NaH2PO4 treatments can increase the quality of pineapple, and MnSO4 is superior to NaH2PO4.
