Název v původním jazyce
A comparative structural and functional study of leaf traits and sap flow in Dracaena cinnabari and Dracaena draco seedlings
Popis výsledku v původním jazyce
Water relations for two remote populations of Dracaena tree species from the dragon tree group, Dracaena cinnabari Balfour f. and Dracaena draco (L.) L., were studied to test our hypothesis that morphological and anatomical differences in leaf structuremay lead to varied functional responses to changing environmental conditions. Sap flow measurements were performed using the heatfield deformation method for four Dracaena seedlings grown in one glasshouse and two greenhouses, and leaf traits related toplant?water relationships were characterised. All traits studied confirmed that D. cinnabari leaves are more xeric in their morpho-anatomical structure compared with D. draco leaves. No radial sap flowvariability was detected in D. draco plant stems, whereas sapflowwas found to be higher in the inner part of D. cinnabari stems. The regular occurrence of reverse sap flow at night in both Dracaena species was consistent with a staining experiment.
