Limitations to photosynthesis in coffee leaves from different canopy positions

Plant Physiology and Biochemistry, 2008
Limitations to photosynthesis were explored in leaves from four canopy positions of field-grown, unshaded coffee (Coffea arabica L.), a tropical tree species classified as shade-obligatory. Overall, compared to shade (lower) leaves, sun (upper) leaves had higher net carbon assimilation rate (A) (4.5 against 2.0 micromol m(-2)s(-1) at most) associated ...

Analysis of DREB1D gene sequence in different Coffea genotypes : S03P07 [PDF]

, 2013
In several plant species, the DREB genes play a key role in responses to abiotic stress. Since the development of molecular markers is one of the major goals for accelerating breeding programs, a study was done to evaluate the sequence variability of the

PHIALOMYCES MACROSPORUS REDUCES CERCOSPORA COFFEICOLA SURVIVAL ON SYMPTOMATIC COFFEE LEAVES [PDF]

Coffee Science, 2019
<p>Saprobe fungi and necrotrophic pathogens share the same niche within crop stubble and the search for fungi non-pathogenic to plants that are able to displace the plant pathogens from its overwintering substrate contributes to the disease management.

Consumer study of Indonesian coffee leaves tea as traditional drinks

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Coffee leaf tea is a traditional drink obtained by processing coffee leaves and served as tea. Coffee leaf tea is often found in West Sumatra, known as kawa daun. However, coffee leaves have not been widely known in the general public so that coffee leaf tea consumers are rarely encountered.

Starmaya: The first arabica F1 coffee hybrid produced using genetic male sterility [PDF]

, 2019
In the present paper, we evaluated the implementation of a seed production system based on the exploitation of male sterility on coffee. We studied specifically the combination between CIR-SM01 and Marsellesa® (a Sarchimor line), which provides a hybrid ...

Validation of Coffee seed promoter in Nicotiana tabacum [PDF]

, 2010
Promoters that restrict transgenic expressions in a specific organ or tissue and, at a certain stage of plant development or in response to stress are extremely desirable for the improvement of agronomic species by transgenesis.

Identification of Colletotrichum species associated with anthracnose disease of coffee in Vietnam [PDF]

, 2010
Colletotrichum gloeosporioides, C. acutatum, C. capsici and C. boninense associated with anthracnose disease on coffee (Coffea spp.) in Vietnam were identified based on morphology and DNA analysis. Phylogenetic analysis of DNA sequences from the internal
