- 摘要:
- 以番茄为试材，分别在缓苗后期、现蕾期和坐果期喷施植物内生菌次生代谢产物，在坐果期喷施后的10、20、30 d时，比较分析了番茄形态及生理生化等各项指标，以探究其对设施番茄生长特性和生理生化指标的影响。结果表明：次生代谢产物可明显促进番茄生长和缓解低温对番茄植株造成的伤害，株高、茎粗、叶长、叶宽比对照组均有不同程度的提高；处理组丙二醛（MDA）含量分别比对照组低1500%、735%和1429%。叶绿素含量分别比对照组高1327%、1500%和1957%。可溶性糖含量分别比对照组高846%、2759%和4393%。可溶性蛋白质含量分别比对照组高1045%、1254%和1469%。说明植物内生菌次生代谢产物具有较好的应用前景。
- Abstract:
- The secondary metabolites of endophytes was sprayed on tomato plants at late recovering stage,budding stage and fruit setting stage of tomato，separately.Effect of the secondary metabolites of endophytes on the growth characteristics and physiological and biochemical of tomato was studied after 10,20 and 30 days by spraying the secondary metabolites of endophytes on tomato in fruit setting stage.The results showed that the secondary metabolites of endophytes could promote the growth of tomato and relieve the damage on tomato plant caused by low temperature.The plant height，stem diameter,leaf length,leaf width increased compared with control group.The content of MDA at the three stages was decreased by 1500%,735% and 1429% compared with control group.The chlorophyll content was increased by 1327%,1500% and 1957%.The soluble sugar content was increased by 846%,2759% and 4393%.The soluble protein content was increased by 1045%,1254% and 1469%.It indicated that the secondary metabolites of endophytes had bright prospects of applications.
