Epiphytic Bromeliads

Vascular epiphytes contribute up to 35% of the plant diversity and foliar biomass of flowering plants. The family Bromeliaceae is a monophyletic group of plants native to the Neotropics. Epiphytic bromeliads form associations with distinct groups of organisms but their relationship with foliar fungal endophytes remain underexplored. In this study we examined the relationship of foliar fungal endophytes to host photosynthetic pathways and associated ecophysiological traits. We sampled the fungal endophyte communities of 67 host individuals in six epiphytic bromeliad species differing in C3 and crassulacean acid metabolism (CAM) photosynthetic pathways. We tested whether endophyte assemblages were associated with ecophysiological leaf traits related to host photosynthetic pathways. Our results indicate that (1) C3 and CAM bromeliads host dissimilar endophyte assemblages, (2) endophyte communities in C3 bromeliads are characterized by variable relative abundances of fungal orders; conversely, CAM associated endophyte communities were characterized by consistent relative abundances of fungal orders, and (3) endophyte communities in bromeliads are distributed along a continuum of leaf toughness and leaf water content. Taken together, our study suggests that host physiology and associated ecophysiological traits of epiphytic bromeliads may represent biotic filters for communities of fungal endophytes in the tropics.

Severity Of The Disease

Correlations between two ecophysiological traits of 13 Fusarium strains (viz., ability to develop saprophytically in a disinfected soil and respiratory activity) and their capacity to protect a flax crop from vascular fusariosis were established for one soil type. The ability of Fusarium strains to reduce the severity of the disease (efficiency) differed greatly. The most competent ones lowered the death rate by 80%, while the least competent had virtually no effect. Classification based on strain efficiency differed depending on whether it was performed on disinfected soil or on soil not heat treated. When the abilities of strains to colonize disinfected soil were estimated by enumeration on agar plates, Fusarium oxysporum strains proved superior to Fusarium solani due to their production of more numerous conidia, and therefore greater numbers of colonies, without significantly increasing biomass. Respiratory activity ranged from moderate to low. A clear, positive correlation was found between the respiratory activity and the efficiency of the strains grown in untreated soil, while the correlation was not significant in the disinfected soil. In the latter case, however, efficiency was correlated with the saprophytic development of the strains. [Journal translation]

AbstractThe impacts of year-round nocturnal warming or late spring rain exclusion on three plant functional types were studied in a plot-scale climate simulation experiment in a semiarid sand forest-steppe of Central Hungary. Ecophysiological traits were followed through six years for the C
