Panicle blast (Pyricularia grisea) in upland rice causes significant yield losses depending upon the environmental conditions and nutritional status of the plant at the grain-filling stage. Four field experiments were conducted to evaluate the influence of mineral nutrients on panicle blast of four upland rice genotypes on an oxisol. Panicle blast severities of four genotypes were related to nutrient concentrations in panicle tissues. Nitrogen (N), phosphorus (P), and magnesium (Mg) contents in tissue were significantly (P<0.01) and positively correlated, whereas potassium (K) and calcium (Ca) were negatively correlated with panicle blast severity. While the relationship between tissue N concentration and disease severity was quadratic, it was linear for K concentration. The correlation between tissue contents of N and P were positive and highly significant (r=0.75 P<0.001). Micronutrient tissue concentrations were not significantly correlated to panicle blast severities except for zinc (Zn). The low panicle blast severities of improved cultivar Guarani were associated with high K and Zn and low N, P, and Mg tissue concentrations. |

This study aimed to compare the spatial and the height distribution of three plant species between two rupestrian field communities, one preserved (A) and the other cultivated (B). One 50 × 100 m plot was delimited in each community and the populations of Eremanthus incanus, Lychnophora pinaster and Vellozia caruncularis were assessed for height and spatial distribution (using the Ripleys?s L-function). In community A, 4,098 individuals were counted, mostly L. pinaster, against 220 individuals in community B, prevailing E. incanus. An inverted-J pattern was observed for height distribution in both communities, however, with lower frequencies in B. Regular spatial distribution was found for E. incanus and V. caruncularis in community A, whereas the pattern for L. pinaster depended on the scale of analysis. The spatial distribution of all species differed between communities. The Ecological Park Quedas do Rio Bonito contributes to the conservation of these rupestrian field species. |
