Abstract:
Taking Amorpha fruticosa as test material,using soil dressing,the effects of different dosage of paclobutrazol(10,50,100,150,200 mg?L-1)on growth of A.fruticosa were studied,to explore the effect mechanism of PP333 on A.fruticosa.The results showed that PP333 could effectively inhibit A.fruticosa plant height growth,increase its base diameter,the content of soluble sugar,soluble protein and the activity of POD were effectively increased,the content of MDA was effectively decreased.PP333 could effectively improve the morphological characteristics of A.fruticosa,by improving its osmotic adjustment ability,oxidation resistance and photosynthetic material,etc.,it also increased A.fruticosa resistance.Using the membership function method to evaluate the regulation effect of each treatment,150 mg?L-1 PP333 treatment had the best effect.
