“…High soil moisture at maturity period also reduced termite infestation, consequently, lower stalk and root lodging. However, incidence of leaf blight was also higher in 2002, a condition that is often encouraged by high moisture during the growing period (Ekpo and Esuruoso, 1977;Agrios, 1988;Amadi, 1998). The desire of maize breeders is that increased grain yield would be associated with the streak resistant gene block accompanied by negligible changes, if any, in other traits (Fakorede et al, 2001).…”

Five new generations of maize streak virus (MSV) resistant varieties were evaluated along with two checks in replicated trials and for two years in a southern guinea savanna ecology of Nigeria, which is an endemic zone for the disease. Difference in grain yield between favourable growing season in 2002 and unfavourable season in 2001 was 1.68 t/ha -1 , representing 30.2% yield increase of 2001 performance. Results further showed that while both rust and streak diseases appeared to have been put in check, the genotypes showed slight susceptibility to leaf blight and curvularia leaf spot, ranging from 5-7 and 4-8 percent (%) respectively. Genotypic differences were significant for grain yield, agronomic traits as well as incidences of leaf blight and curvularia leaf spot. Acr 91 Suwan-1-SR C 1 was the most productive of new generations of MSV resistant varieties, having yielded significantly higher than OPV check by 32 percent (%) and comparable with the hybrid check for grain yield. The variety could therefore serve as replacement to existing cultivar and also as source of genes for future maize breeding activities in the development of superior maize varieties for the southern guinea savanna ecology.

“…Os sais podem induzir ao clareamento da colônia uma vez que são nutrientes capazes de interferir na atividade enzimática, metabolismo dos carboidratos, balanço iônico, formação de aminoácidos, nucleotídeos e vitaminas (23). Porém, não se deve menosprezar a capacidade intrínseca do microrganismo em captar e utilizar os nutrientes do substrato suprindo, assim, suas exigências nutricionais (17,32). Tal capacidade pode ser devida aos isolados pertencerem a raças fisiológicas distintas, conforme sugerido por Azevedo (6), e serem diferenciados não pela morfologia, mas somente através de estudos fisiológicos e moleculares.…”

Caracterização morfofisiológica de isolados do gênero Cylindrocladium

Com o objetivo de caracterizar o "complexo" gênero anamórfico Cylindrocladium, dezoito isolados foram cultivados em meios de cultura distintos, mantidos sob diferentes temperaturas, além de ter conídios e vesículas terminais analisados morfologicamente para identificação correta das culturas. Inoculações em diferentes hospedeiros foram, também, realizadas para avaliação do comportamento patogênico dos isolados estudados. Com relação aos caracteres morfológicos, pôde-se observar que ocorrem alterações nas dimensões de conídios e na morfologia da vesícula terminal devido, provavelmente, à mudança do substrato de cultivo. Porém, a variabilidade natural nas características dessas estruturas é tão elevada que dificulta a identificação correta dos isolados. Em uma mesma cultura, por exemplo, foram observadas vesículas terminais de diferentes morfologias. Pôde-se constatar que existem diferenças patogênicas e fisiológicas entre os isolados, uma vez que houve a formação de grupos distintos quando tais características foram consideradas. Estas diferenças, provavelmente, sejam devidas à constituição genética distinta existente entre os isolados.
