Histology of somatic embryogenesis in Coffea arabica L.
Biologia, 2018The objective of this study was to characterize the histodifferentiation of somatic embryogenesis obtained from leaf explants of C. arabica. Therefore, we histologically analyzed the respective stages of the process: leaf segments at 0, 4, 7, 15 and 30 days of cultivation, Type 1 primary calli (primary calli with embryogenic competence) and 2 (primary ...

Evaluation of Arabica Coffee (Coffea arabica L.) Genotypes for Biometrical Traits
Madras Agricultural Journal, 2013An experiment on arabica coffee (Coffea arabica L.) genotypes for biometrical traits evaluation was carried out at Chettalli in Karnataka during the period 2004 - 2007 to study the variation in the vegetative and yield component traits. Eighty five genotypes exhibited significant variation for all the traits in three seasons of the study.

Identification of abscisic acid in flower buds of Coffea arabica (L.)
Planta, 1970Extracts of flower buds of Coffea arabica (L.) collected before and after bud break contain abscisic acid. This was demonstrated using thin layer chromatography and gas chromatography combined with mass spectroscopy. Abscisic acid accounts for about 75% of the inhibitory activity in the acidic extract. The possible role of abscisic acid in the dormancy

Breakdown of Caffeine in the Leaves of Coffea arabica L.
Nature, 1965THE caffeine content of older Coffea leaves decreases after an initial increase in young leaves1. There are two possible explanations of this fact; first, a chemical transformation of caffeine; secondly, a translocation from the leaf to other organs. The object of these investigations was to find out if there is a breakdown of caffeine in the Coffea ...
