| 摘 要： | 研究了硼（B）、钼（Mo)营养8种处理对青花菜花球产量和活性氧代谢的影响。结果表明，B、Mo营养与青花菜花球产量及活性氧代谢有密切的关系，B、Mo营养具有明显的互作效应，当B浓度相同时，随着Mo浓度的提高，CAT活性与ASA含量也随之提高；当Mo浓度相同时，随着B浓度的提高，CAT活性与ASA含量也随之提高。适宜的B、Mo配施可提高SOD、POD、NR的活性，降低MDA含量与自动氧化速率，抑制膜脂过氧化,提高花球产量。青花菜花球的生产能力与细胞保护酶（SOD、POD、NR、CAT）活性呈极显著的正相关，与MDA含量呈显著的负相关。

| Abstract: | The effects of eight B Mo treatments on curd yield and active oxygen metabolism in broccoli were studied.The results indicated that there was a close relationship between B Mo nutritions and curd yield,as well as active oxygen metabolism of leaves in broccoli.There was a marked interaction between B and Mo nutrition.When the concentrations of B were the same,catalase(CAT)activity and antiscorbutic acid(ASA)content increased with the increase of concentrations of Mo.When the concentrations of Mo were the same,CAT activity and ASA content increased with the increase of concentration of B.The combination of B and Mo nutritions at a proper level(B 6Mo 5 treatment)could increase superoxide dismutase(SOD),peroxidase(POD),nitrate reductase(NR)activity,decrease malondialdehyde(MDA)content and autoxidation rate,inhibit membrane lipid peroxidation,and increase curd yield.There was a significant positive correlation between productive capability of curd and the activities of protective enzymes(SOD,POD,CAT and NR),and a significant negative correlation with the MDA content. |
