摘要/Abstract

摘要： 研究了红栌、樱桃砧木和石榴嫩枝扦插过程中, 喷施MHS代谢调节剂对其插条成活率、生根
率和保绿时间的影响, 及其叶片中可溶性糖、可溶性蛋白质、叶绿素含量和SOD活性的变化。结果表明,
MHS对扦插难、易生根植物生长均有明显促进作用。对红栌插条而言, 经生根剂浸根并喷施MHS后插条
的成活率和生根率均最高, 与清水对照相比分别提高了895173%和735172% , 保绿时间延长了28185 d。
插条的可溶性糖、可溶性蛋白质和叶绿素含量随处理天数的增加而呈增高趋势, 且均高于浸根处理的对照
组。SOD活性在处理初期活力有所下降, 后期明显增强。由此可见, MHS是通过对插条生理生化代谢的调
控来提高其成活率的。

Abstract: Abstract: The effectps ofMHSmetabolism regulator on cuttingspsurvival rate, rooting percent and green
time, were studied by sp rayingMHS in the cutting of purpureus, cherry colt and pomegranate. The variation
in the contents of solubility carbohydrate, soluble p rotein and total chlorophyll and the activities of superoxide
dismutase ( SOD) were also discussed in the experiment. The results showed thatMHS could imp rove growth
of the p lants which root either easy or hard. The highest survival rate and rooting rate were obtained after the
cuttings of purpureus were soaked with rooting reagent and sp rayed byMHS. The survival rate and rooting rate
with this treatmentwere increased by 895173% and 735172% separately. The green time was 28185 d longer
than the control. The contents of solubility carbohydrate, soluble p rotein and chlorophyllwere increased grad2
uallywith the treated days. The activities of SOD were descend firstly, then enhanced. This showed thatMHS
increased survival rate by regulating the metabolism of cuttingps physiology and biochemistry.
