【Abstract】 The pod development regularity of Descurainia Sophia was studied through measuring the length and the volume of pods and weighting fresh and dry pods. And estimated the pod development regularity briefly: (1) Pods elongated at first and reached their maximum length at about 15-18 days after flowering. (2) The fresh and dry weight of pods reached their maximum values when the pods reached their maximum volume.更多还原
