Abstract:
Using the Caragana intermedia and seeds of Zea mays L.,Sorghum sudanense and Sorgum bicolor×S.sudanense as test materials，by the petri dish with filter paper method，using distilled water as control，the leaching of different gradient (0.5 mg?mL-1，1.0 mg?mL-1，5.0 mg?mL-1，10.0 mg?mL-1，25.0 mg?mL-1) the Caragana intermedia floral water extract effect on receptor crop seed germination and seedling growth were studied，in order to provide a theoretical basis and useful reference for production of agroforestry systems and construct.The results showed that with the increase of Caragana intermedia water extract concentration，receptor crops，Sorghum sudanense,Sorgum bicolor×S.sudanense seed，the average germination rate and germination index were promoting at the low concentration and high concentration inhibition effect，but different concentrations of aqueous extracts had the difference of 3 kinds of crop seed germination the influence of the concentration of 1.0 mg?mL-1，3 kinds of crop seed relative germination had no significant difference (P>0.05)，in addition to Zea mays L.，the average germination rate of 2 other receptors of crop seeds were promoted，and the pacetter greatest role，RI=13.70% in high concentration leaching；liquid (C≥5.0 mg?mL-1) with 3 kinds of receptor crops seed germination index showed significant difference with the control (P<0.05).Zea mays L.，Sorghum sudanense of radicle and plumule of Caragana intermedia floral water leaching liquid extraction effect showed the concentration effect；three receptor crops seedlings with extraction solution concentration increased as the hormesis，the high concentration of leaching liquid of gaodan grass seedling height had the strongest inhibitory effect.Floral dip extracts of Sorghum sudanense and Sorgum bicolor×S.sudanense seedling dry weight of allelopathic effected hormesis effect，and on maize seedling dry weight higher concentrations were inhibitory effect.Caragana intermedia floral water immersion extract of receptor crops of combined effect sizes in order to Sorgum bicolor×S.sudanense >Zea mays L.>Sorghum sudanense.
