摘要： The effect of gibberellic acid (GA(3)) in overcoming the potential allelopathy of ten plant species (Alnus nepalensis, Amygdalus persica var. nectarina, Camellia sinensis, Chaenomeles sinensis, Eucalyptus robusta, Juglans sigillata, Prunus salicina, Punica granatum, Zanthoxylum bungeanum, and Zea mays) on seed germination of Gentiana rigescens, a medicinal plant, was examined. It was observed that GA(3) had significant effects on overcoming the inhibitions of some of these plants. With GA(3) pretreatment, seed germination of G. rigescens was increased from 10.0 to 62% and 2.5 to 50.5% in the leaf extracts of Camellia sinensis and Chaenomeles sinensis, respectively and from 37.0 to 60.0%, 25.5 to 61.0%, 10.0 to 59.0%, 15.5 to 59.0%, and 23.5 to 59.5% in the root extracts of Alnus nepalensis, Camellia sinensis, Chaenomeles sinensis, Eucalyptus robusta, and Prunus salicina, respectively. The plumule length of G. rigescens with GA(3) pretreatment in aqueous root extracts of Chaenomeles sinensis was significantly longer than that for the control. The results suggest GA(3) pretreatment would be effective for promoting germination of Gentiana rigescens seeds in a Gentiana rigescens-Camellia sinensis (or Chaenomeles sinensis) agroforestry system.
