Abstract

Abstract: Based on energy spectrum analysis on absorbing laws to nutrient elements for tissue of sucking roots．the results were as follows：1．It showed two peaks which appeared at the 4—6 hour and the 10-24 hour after treatment by nutrient liquid respectively for root to absorb nutrient elements：2． The absorption laws and distribution of nutrient elements in different root tissues of Ginkgo were relative to the types of element and ion in culture liquid．and to characters of requirement of root system to nutrient element：3． There were more accumulate of potassium and sodium in root system of Ginkgo，which showed that Ginkgo biloba Was a plant of strong metabolism and salt endurance．

Key words: Ginkgo biloba L．, Analysis of X-ray energy spectrum, Stage of dynamic transition, Root, trient elements
