摘　　要：运用烧结钕铁硼磁性材料N35对切花月季瓶插液和花朵进行不同的磁化处理,研究磁化处理对切花月季衰老的影响,探索切花月季新的保鲜措施。结果表明,5个磁化处理切花月季的鲜重损失率均低于对照;水分吸收速率随着瓶插天数的增加而降低,各处理均能抑制其降低速度;各处理均能不同程度地延缓花瓣相对电导率的增加,抑制花瓣中丙二醛的生成;各处理均能不同程度地促进花蕾直径的增加,A、D、C处理分别延长切花月季的瓶插寿命3、2、2 d;对瓶插液磁化1次比反复磁化多次或正交磁化更有利于减缓花瓣细胞内含物质的渗漏。Using sintered Nd-Fe-B magnets N35 on vase liquid and flowers to study the magnetic treatments＇ effect on senescence of cut rose. Five magnetic treatments compared with CK showed that fresh weight loss rate were lower, and the decrease speed of water absorption rate could be inhibited; delaying the increase of relative electric conductivity and inhibiting the formation of malondialdehyde in petals while increasing flower diameter in varying degrees; the treatments of A, D and C respectively extended the vase life of 3 days, 2 days and 2 days. The vase liquid was magnetized a time was more conducive to slow down the leakage of petals＇ cell contents than repeatedly or orthogonal magnetization.
