| 摘 要： | 通过大田试验研究菠萝谢花后喷施稀土溶液对菠萝产量品质和抗氧化酶系统的影响。结果表明,200mg/L硝酸铈处理效果最好,果实横、纵径分别较对照增加5.08%、10.82%,单果重提高20.13%;Vc含量提高135.81%,糖酸比增加17.75%;SOD活性显著提高,增幅达69.96%,POD活性降低,但与对照没有显著差异。

| Abstract: | The effects of Rare Earth on the yield and quality and protective enzymes of Pineapple were studied by field experiments. The results showed that the effects of 200 mg/L Cerium nitrate treatment were the best. The width and length of pineapple fruits increased by 5.08%, 10.82%; Fruits quality increased by 20.13%; Vitamin C improved by 135.81% and Sugar-acid ratio improved by 17.75%; SOD activity increased by 69.96% and POD activity reduced. |
