“…Three of the species found in this study were previously regarded as pathogen to melon plants: Fusarium oxysporum, F. solani and Myrothecium roridum (Marinho et al 2002;Muniz et al 2004;Viana et al 2001). However, it is not possible to say if they were in the rhizosphere as saprobe or pathogen.…”

Rhizosphere soil samples were collected in a semiarid area, in the region of the São Francisco River valley, Petrolina, Pernambuco state, Brazil, to study the diversity of filamentous fungi in a soil cultivated with melon (Cucumis melo L. cv. Gold Mine) and receiving different organic amendments: Treatment 1 (control, without organic compost); T2 (77% coconut fiber, 20% goat manure and 3% K2SO4); T3 (10% Ricinus communis leaves and stems, 50% Pennisetum purpureum leaves and 40% goat manure); T4 (77% coconut fiber, 20% goat manure and 3% termophosphate); T5 (47% Pennisetum purpureum leaves, 50% goat manure and 3% K2SO4); and T6 (57% Pennisetum purpureum leaves, 40% goat manure and 3% termophosphate). Fungal isolation was carried out by the serial dilution technique to 1:1000. The Sorensen index of similarity, frequency and distribution of the fungi were evaluated. Seventy-eight species of filamentous fungi were isolated and identified, plus several Basidiomycota (04) and Mycelia sterilia (02). The predominant genera were Aspergillus and Penicillium, with 15 and 13 species, respectively. A greater number of species was found in the sowing period (49), and in relation to the organic fertilization, treatment 6 provided the greatest species diversity (43 species). Most of the species are saprobes and only a few are considered to be potential pathogens on melon plants, such as Fusarium oxysporum, F. solani and Myrothecium roridum.

“…Esse fato intensifica a deterioração, resultando em percentuais muito baixos de germinação pós-envelhecimento (Muniz et al, 2004). Para controlar este fator, tem-se utilizado soluções saturadas de sais durante a realização do teste (Jianhua & McDonald, 1996); procedimento este considerado eficiente na classificação do vigor de lotes de sementes de cenoura (Rodo et al, 2000).…”

RESUMOO trabalho teve por objetivo comparar testes de vigor para a análise da qualidade fisiológica de sementes de cenoura, classificadas por tamanho e armazenadas por diferentes períodos. Seis lotes de sementes população 'Londrina' foram submetidos a testes de germinação, tetrazólio, envelhecimento acelerado com água, com solução salina e emergência de plântulas. O teste de emergência de plântulas destaca-se na classificação dos lotes quanto às diferenças de vigor. A combinação solução salina com 48 ou 72 h de exposição é a mais adequada para o teste de envelhecimento acelerado. As sementes de maior tamanho apresentam qualidade fisiológica superior às menores.Palavras-chave: Qualidade fisiológica; germinação; Daucus carota L. ABSTRACTThis work had the purpose to compare the efficiency of vigor tests for evaluation of physiological quality of carrot seeds, ranked for size and stored by different periods. Six lots of carrot seeds from 'Londrina' population were tested for germination, tetrazolium, accelerated aging traditional, accelerated aging modified and seedling emergency. The seedling emergence test is distinguished in classification the lots by the vigor differences. The combination salt solution with 48 or 72 h of exposure is adjusted for the accelerated aging test. The seeds of larger size have higher physiological quality to smaller.
