Abstract：In order to study the relationship between the peduncle articulation anatomical structure and the shattering of Fagopyrum Mill,the anatomy of the peduncle articulation in flower and inflorescence samples from Fagopyrum Mill plants were studied by means of comparative observation and paraffin section.The results showed that there were abundant starch grains accumulating in the parenchyma cells of peduncle in the flowering,and there was no obvious difference in vascular bundle.The peduncle articulation was a special structure whose cells were small and closely arranged,similar to that of an abscission layer.The positions of peduncle articulation on the peduncles were different among 7 types of Fagopyrum.The morphology of articulation was more closely related to shattering.The depression of peduncle articulation usually resulted in shattering.The function of the peduncle articulation is similar to abscission layer.In general,the flowers fall off the articulation to avoid the loss of nutrition,which can promote the growth and reproduction of plants.
