Studies on the Responses of Root, Shoot and Drought Resistance in the Seedlings of Forage Triticale to Water Stress

Abstract

In order to investigate the identification index of drought resistance in the forage triticale seedlings, 30 triticales with different genotypes were identified by 20%–PEG6000. Results showed that responses of each gene to water stress were relatively obvious, water content decreased, the root-shoot ratio enhanced, and leaf curvature and root hyperplasied; There was significant difference among different genotypes, material 27,29,30 showed a good representation to water stress, and their root status were also good. The variation regularity of water content and root hyperplasia was good and they had a great significant correlation. But the variation of root-shoot ratio is relatively complex, other factors should be taken further consideration in the application.
