Abstract: Archontophoenix palms, utilized both as ornamental species and as a source of high-quality heart of palm, are susceptible to sooty mold, a disease coupled with aphid infestation, which affects photosynthesis and causes unpleasant, darkish palm appearance. Scoring rates for sooty mold resistance and three growth traits were assessed under field conditions in 24 open-pollinated half-sibs families, 28 months after planting, aiming to identify genetic variability for sooty mold resistance; estimate genetic paramet… Show more

“…Genetic gains of 25% and 28% during 2008 and 2009 indicated that selection of the top 5% of the population can be expected when visual symptomatic selection is used. Bovi et al (2004) also reported high narrow sense heritability estimates and moderate genetic gain for sooty mold resistance in Archontophoenix palm.…”

“…Studying different palm trees species of Arecaceae, Carvalho et al (2008) andFarias Neto et al (2007) obtained heritability values of 0.90 and 0.24, respectively, for the leaf number trait in E. oleracea. Bovi et al (2004) found a lower value of 0.10 for the same trait in Bactris gasipaes. In E. oleracea, the average heritability of progenies for plant height obtained by Farias Neto et al (2012) was 0.64, close to the findings of this study (ℎ " #$ % = 0.63) (Table 4).…”

“…Registou-se que as espécies botânicas mencionadas estavam a fazer sombra à escultura e a aumentar o teor de matéria orgânica desta pela queda das suas folhas. Estas observações e a pesquisa efetuada levaram-nos à hipótese de o filme negro ser fumagina, também conhecida como sooty mould [11,[20][21][22][23][24]. A fumagina é um termo genérico para um produto de cor preta causado pelo desenvolvimento de fun-gos (provocada por mais de 200 espécies fúngicas) sobre um melada [24][25][26][27] (honeydew), produzido por insetos alimentadores de seiva (especialmente seiva doce), hóspedes das plantas [11,20,24].…”

“…Essas gotas caem das folhas para outras zonas das árvores ou ainda, como neste estudo, sobre a escultura [14,24,26,30]. Após a deposição, vão criar um revestimento açucarado pegajoso [11][12][23][24] sobre os materiais anteriormente mencionados, basicamente formado por sacarídeos [11,15,[20][21]27], aminoácidos, proteínas, minerais, vitaminas e outros compostos orgânicos [11-12, 15, 31]. Neste revestimento desenvolve-se um biofilme fúngico enegrecido (Figura 13) produzindo esporos e uma massa superficial negra [11,[20][21]27].…”
