The black spot of citrus (Citrus sp.) is caused by Guignardia citricarpa with ascospore production depending on temperature, leaf wetness, and rainfall. The number of ascospores produced was monitored using a spore trap and climatic factors were recorded using an automated meteorological station of 'Natal' and 'Valencia' sweet orange (Citrus sinensis) orchards in Mogi Guaçu in the state of São Paulo, Brazil, from November 2000 to March 2001. The fruits were bagged to prevent infection and the bags removed from different sets of fruit for one week during each of the 18 weeks of the season in both orchards. Ascospores were produced during the entire experimental period, from spring through summer, primarily after rain events. In both orchards, ascospore production reached a peak in January and February. Ascospore production was related to leaf wetness only in the Natal orange orchard but was not related to total rainfall or temperature in either orchard. Disease was most severe on fruit exposed the 7th, 8th, and 13th weeks after beginning the experiment in both cultivars as well as after the 16th week for 'Natal'. There was a strong relationship between disease severity and total rainfall for both orchards and a weak correlation between temperature and severity in the 'Natal' block only. There was no relationship between severity and leaf wetness or ascospore numbers. |

As pesquisas de sementes na região tropical semi-árida são desenvolvidas no Centro de Pesquisa Agropecuária do Trópico Semi-Árido da EMBRAPA, pela Empresa de Pesquisa Agropecuária de Pernambuco e pela Universidade Federal do Ceará. Os trabalhos desenvolvidos concentram-se nos problemas relativos a salinidade do solo, tolerância a seca, práticas culturais, sanidade da semente, produção de sementes florestais e ao potencial de uso do vale do São Francisco na produção de sementes. |
