烯效唑+褪黑素对水果萝卜先期抽薹及品质的影响

Effects of aliconazole+melatonin on early bolting and quality of fruit radish

为探究褪黑素复配剂对冀东地区水果萝卜抽薹的抑制效果,以绿如玉水果萝卜为试材,待萝卜4~5片真叶时,对叶面喷施不同浓度的褪黑素复配剂,于萝卜生长50 d采样。对褪黑素复配剂处理后水果萝卜的抽薹率、肉质根性状指标和营养品质指标等数据进行比较与分析。结果表明,600 mg·L^(-1)烯效唑+750μmol·L^(-1)褪黑素抑制萝卜先期抽薹综合效果最佳。该处理抽薹率为12.90%,较CK(清水)降低了36.1%;单根质量为450 g,较CK提高了2.28%;可溶性蛋白含量(w,后同)为4.18mg·g^(-1)较CK提高了23.3%;可溶性糖含量为1.63%,较CK提高了41.74%;可溶性固形物含量为5.99%,较CK提高了43.3%。因此,褪黑素复配剂喷施处理最佳浓度是600 mg·L^(-1)烯效唑+750μmol·L^(-1)褪黑素。

In order to investigate the inhibition effect of melatonin compound on the bolting effect of fruit radish in eastern Hebei province,the LvRuYi fruit radish was used as the test material.When 4-5 true leaves of radish were left,different concentrations of melatonin compound were sprayed on the leaf surface,and samples were collected 50 days after radish growth.The data of bolting rate,fleshy root traits and nutritional quality of fruit radish treated with melatonin were compared and analyzed.The results showed that 600 mg·L^(-1) enlobuzole+750μmol‧L^(-1) melatonin had the best comprehen-sive effect on early bolting of radish.The bolting rate of the treatmnet was 12.90%,which was 36.1%lower than CK;single root mass was 450 g,which was 2.28%higher than CK;the soluble protein content was 4.18 mg·g^(-1),which was 23.3%higher than CK;the soluble sugar content was 1.63%,which was 41.74%higher than CK;and the soluble solids content was 5.99%,which was 43.3%higher than CK.In conclusion,the optimal concentration of melatonin compound spray treatment is 600 mg·L^(-1) enlobuzole+750μmol·L^(-1) melatonin.
