S (leaves>flowers>new stems>roots>aging stems),aging organs are rich in Ca .Fe.Na.(roots>aging stems>flowers>leaves).(2)There exist many notably relevant pairs of elements among different elements. There are more pairs in leaves, flowers, receptacles than in new stems and aging stems, while leaves stalks and roots have the least pairs.
