Avaliação de clones de café conilon de ciclo de maturação precoce quanto a produtividade e severidade da ferrugem. [PDF]

, 2011
A ferrugem do cafeeiro é causada pelo fungo Hemileia vastatrix Berk. & Br. Essa doença é considerada a mais importante para a cultura do café. Algumas populações de café conilon são altamente suscetíveis, outras totalmente resistentes, e outras, ainda ...

Genomic‐assisted breeding for climate‐smart coffee

The Plant Genome, Volume 17, Issue 1, March 2024.
Abstract Coffee is a universal beverage that drives a multi‐industry market on a global basis. Today, the sustainability of coffee production is threatened by accelerated climate changes. In this work, we propose the implementation of genomic‐assisted breeding for climate‐smart coffee in Coffea canephora.

Essential oils for rust control on coffee plants Óleos essenciais no controle da ferrugem em cafeeiro

Ciência e Agrotecnologia, 2012
Rust is considered the most important disease in coffee because it causes severe defoliation in plants and, consequently, reduction in productivity. This study evaluated the in vitro effect of essential oils of cinnamon, citronella, lemongrass, clove ...

Efeito da ferrugem e da supressão de nitrogênio no nível transcricional do gene nitrato redutase (CaNR) em Coffea arabica L. [PDF]

, 2014
O objetivo do trabalho é avaliar se a ferrugem do cafeeiro (Hemileia vastatrix) pode modular a resposta transcricional de um gene-chave na assimilação de nitrogênio (N), a nitrato redutase, em função da restrição do nutriente e da resposta do cultivar ao

Impact of climate on a host–hyperparasite interaction on Arabica coffee in its native range

Journal of Applied Ecology, Volume 61, Issue 3, Page 538-550, March 2024.
Our findings highlight that coffee leaf rust and its hyperparasite are both affected by shade cover and temperature, but in different ways. On the one hand, these niche differences lead to the worrying prediction that levels of coffee leaf rust will increase, and its hyperparasite will decrease, with climate change.

High-density genetic mapping for coffee leaf rust resistance. [PDF]

, 2016
Coffee leaf rust caused by the fungus Hemileia vastatrix causes considerable economic losses for coffee producers. Although agrochemical products can provide sufficient disease control, the use of resistant cultivars is a safer alternative.
