| Abstract: | In the present study,the process of flowerbud differentiation and development of Platycodongrandiflorum was divided into 6 stages according to the morphological changes of its floweringorgans: inflorescence primodium differentiation stage,flowerbud primordium differentiation stage,potal differentiation and formation stage,sepal primordium differentiation stage,stamenprimordium differentiation stage and pistil primordium differentiation stage. Under the climaticconditions of Nanchuan county,Sichuan province,flowerbud differentiation was found to startaround 20th,March and complete in mid-June. |
