Abstract:
Effects of the leaf-clipped treatment on growth and physiological properties of Rehmannia glutinosa were studied. Result showed that with the increase of the cutting leaves degree, growth rates of shoots and roots were decreased, sugar contents declined, chlorophyll contents decreased and root activities also inhibited. Compared with the normal plant (CK), the root inhibit rates in T1, T2, T3 were 17.53%, 33.41%, 59.47%, respectively. Physiological indexes including chlorophyll contents, root activities and sugar contents also were impacted by the leaf-clipped treatment. The results indicate that to balance source-sink relationship is a very essential method for improving production of R. glutinosa.
