| 中文摘要: |
| Ｎ、Ｋ水平与柠檬抵御流胶病病原菌侵染能力有密切关系。在营养液中Ｎ浓度大于２４０ｍｇ／ｋｇ，树体对流胶病抵御能力降低；在Ｋ浓度小于２２０ｍｇ／ｋｇ范围内，提高Ｋ水平能明显提高树体抗流胶病的能力。叶片中全多酚的含量与树体抗流胶病能力强弱有关，在营养液中Ｎ浓度为２４０ｍｇ／ｋｇ，Ｋ浓度为２２０ｍｇ／ｋｇ时，叶片全多酚含量为９．１７ｍｇ／ｇ，树体具有较强的抗流胶病能力。 |

| The relation between N, K levels and the resistant ablity of lemon trees infection by gummosis pathogen was studied In nutrition solution, N in high level decreased the gummosis resistance of lemon, while increasing K level in suitable range promoted significantly the gummosis resustance Total ployphenols content in leaf was positively correlative with the degree of gummosis resistance of lemon With N 240 mg/kg and K 220 mg/kg, the total polyphenols in leaf was determined in high content, which contributed to the strong gummosis resistance |
