以3年生青钱柳（ Cyclocarya paliurus ）苗木为试材，采用叶面喷施法研究不同质量浓度的多效唑（ PP333）对青钱柳生理特性的影响。结果表明：适当质量浓度的PP333处理能有效促进苗木地茎相对生长量，提高叶片可溶性蛋白、可溶性糖以及药用次生代谢物三萜、山奈酚和槲皮素的质量分数，刺激超氧化物歧化酶（ SOD）、过氧化物酶（ POD）、苯丙氨酸解氨酶（ PAL）活性的升高，但对苗高生长起抑制作用。 PP333质量浓度为400 mg/L时对地茎相对生长量、可溶性蛋白和槲皮素促进作用最佳，与对照相比，分别增加了180．49％、48．14％和100．00％，均达显著水平。 PP333为600 mg/L时对可溶性糖、三萜、山奈酚质量分数以及SOD、POD、PAL活性刺激作用最强，分别比对照增加了32．22％、46．02％、22．88％、46．66％、53．68％和67．51％，差异显著。以上结果说明，适当质量浓度的多效唑处理可调节青钱柳苗木代谢特性，提高苗木抗逆性，刺激药用成分的合成。

The effects of paclobutrazol ( PP333 ) on the physiological characteristics in Cyclocarya paliurus leaves of 3-year-old seedlings were investigated by spraying different contents of PP333 .The stems relative growth yield, content of soluble pro-tein, soluble sugar as well as the drug secondary metabolites including triterpenoid, kaempferol and quercetin in leaves of Cyclocarya paliurus are effectively improved by adding a suitable concentration of PP333 , the activity of superoxide dis-mutase (SOD), peroxidase(POD) and phenylalanine ammonia-lyase(PAL) increase at the high levels, while the seeding relative growth yield are delayed .400 mg/L treatment is the best to promote thestems relative growth yield, content of sol-uble protein and quercetin.Compared with those of the control, the above indexes increase by 180.49%, 48.14% and 100.0%, respectively.600 mg/L treatment can improve the content of soluble sugar, triterpenoid and kaempferol as well as the activity of SOD, POD and PAL with a maximum stimulation.Compared with those of the control, the above indexes increase by 32.22%, 46.02%, 22.88%, 46.66%, 53.68% and 67.51%.The suitable content of PP333 can regulate the metabolic characteristic of Cyclocarya paliurus, increase seedling resistance and stimulate the medicinal components synthesis.
