Influence of Nitrogen in the Anatomical characteristics and yield of tropical grasses
The genus Brachiaria occupies the largest area of sowing pastures in Brazil.Therefore, the knowledge of its quantitative anatomy complements studies as regards its nutritive value.The action of rumen microorganisms on the different plant tissues stresses the importance of its identification and quantification.The major pathway of invasion by rumen microorganisms is constituted by leaf epidermis lesion,although the access by stomata is of great importance in the colonization (Cheng et al.,1984).In this work,it was aimed to evaluate the anatomical characteristics stomatal density (stomata per mm2 ) in the adaxial (SDAD) and abaxial (SDAB) epidermis ; polar stomatal diameters (in μm) in the adaxial ( PSDAD) and abaxial (PSDAB) epidermis ; equatorial stomatal diameters (in μm) in the adaxial (ESDAD) and abaxial (ESDAB) epidermis, and the agronomical characteristics tiller height and number of tillers (NT) and dray matter yield per pot (DMY).
