Conteúdo: |
Knowledge of the chemical composition of plants from Brazilian Cerrados is, considering the vast extention of these drylands, disproportionally slight. On evidence presented in three case studies it is predicted that it will turn out to be extraordinarily diversified, if compared with the chemistry of the adjoining rainforests. Hence, in view of progressive population pressure on these drylands, it is urged to priorize the scrutiny of their plant metabolites. |

Conteúdo: |
Leaf and panicle blast severities and grain yield of some upland rice cultivars were measured in three successive years in field plots unprotected or protected with fungicides. The variation in disease severities in different plots was used to establish relationships between severity of leaf and panicle blast and yield. Linear multiple regression equations for each cultivar by year were developed to estimate the yield decrease in different cultivars per unit increase in disease. Leaf blast severities at maximum tillering or booting stage and panicle blast 25 days after heading accounted for variation in grain yield in most of the cultivars. General equations combining five early and eight medium-duration rice cultivars were developed. The estimated percentage losses in grain yield due to blastwere 2.7 and 1.5 for one percent increase in blast in the early and medium-duration cultivars, respectively. |
