Mineral element content and its seasonal dynamic in Ceratocephalus testiculatus

During April-June 2011, have analysed synthetically dynamic change trend of various mineral elements in plants by measuring content of 7 mineral elements in different organs of Ceratocephalus testiculatus during different growth period in the reserve of Testudo horsfieldi . Results showed that there are 5 change trend of mineral elements that in the vegetative organs root and leaf during different reproductive period of C.testiculatus; content change in reproductive organs flower and fruit during flowering period and seed setting period is obvious; There are different conditions of relative variation of mineral element in different component of C.testiculatus during different reproductive period, because of circulating whether or not; Calciumphosphorus ratio in different modules of C.testiculatus during different growth period over 2:1 is root in the vegetative period and seed setting period.
