主　　题：Aquatic plants Floral longevity Flower economics traits Flower hydraulic traits Terrestrial plants 

摘      要：Maintaining open flowers is critical for successful pollination and depends on long-term water and carbon *** the relationship between how flower hydraulic traits are coordinated in different habitats is poorly ***,we hypothesize that the coordination and trade-offs between floral hydraulics and economics traits are independent of environmental *** test this hypothesis,we investigated a total of 27 flower economics and hydraulic traits in six aquatic and six terrestrial herbaceous species grown in a tropical botanical *** found that although there were a few significant differences,most flower hydraulics and economics traits did not differ significantly between aquatic and terrestrial herbaceous *** flower mass per area and floral longevity were significantly positively correlated with the time required for drying full-hydrated flowers to 70%relative water *** dry matter content was strongly and positively related to drought tolerance of the flowers as indicated by flower water potential at the turgor loss *** addition,there was a trade-off between hydraulic efficiency and the construction cost of a flower across *** results show that flowers of aquatic and terrestrial plants follow the same economics spectrum *** results suggest a convergent flower economics design across terrestrial and aquatic plants,providing new insights into the mechanisms by which floral organs adapt to aquatic and terrestrial habitats.
