Abstract:-The objective of this study was to characterize the nutritional value of forage legumes Mimosa caesalpiniifolia (Benth.), Bauhinia cheilantha (Bong.) and Leucaena leucocephala (Lan.) and evaluate the anatomy of plants incubated and not incubated in the rumen. The experiment was conducted from September 2007 to November 2008. The experimental plot consisted of three useful plants, totaling three plots per block, and four repetitions. Plants were cut at 1 m height at intervals of 70 days; samples of leaf plus s… Show more
“…Furthermore, our results suggested that the leaching rates of K + seem to be driven by the presence of cellular structures associated with resource storage (parenchyma) and transfer (sieve cells) [30], which, in turn, is consistent with the RDA results for the BWA% of the species L. leucocephala, where potassium was the most influenced by the bark absorption capacity. Researchers studying L. leucocephala, Bauhinia cheilantha, and Mimosa caesalpiniifolia observed that the abaxial epidermis was thinner than the adaxial one, and the stomata on the abaxial surface were numerous, with the palisade parenchyma juxtaposed, arranged in a single layer with few intercellular spaces [32]. The presence of K + is the result of the leaching of this ion from the canopy itself [33].…”
Urban trees play a pivotal role in mediating the hydrological and nutrient cycles within urban ecosystems, yet the mechanisms by which bark characteristics influence these processes remain underexplored. This study aimed to investigate the impact of the bark morphology—specifically texture, depth, and number of furrows—on the water absorption capacity and to determine the relationship between this capacity and ion concentration in stemflow across various urban tree species. Our findings reveal significant variations in water absorption and ion concentration related to the morphological traits of bark among tree species, highlighting the intricate relationship between bark physical and chemical characteristics and stemflow nutrient composition. Notably, species with furrowed textures, greater depth, and a higher number of furrows demonstrated pronounced differences in ion enrichment in their stemflow. However, a canonical redundancy analysis suggested a low association between bark absorption capacity and ion concentration, indicating the influence of other, possibly external, environmental factors on ion leaching. The results underscore the complexity of nutrient transport mechanisms in urban trees and show a new understanding of tree bark’s ecohydrological roles. This study contributes valuable insights into ecohydrology science and emphasizes the need for further research to unravel the multifaceted influences on nutrient dynamics in urban landscapes.
