Ecophysiology of the cacao tree

Morphology, ecophysiology and germination of seeds of the neotropical tree Alibertia patinoi (Rubiaceae).

Alibertia patinoi (Rubiaceae) is of economic and cultural importance for communities in the Colombian Pacific and Amazon regions, where it is cultivated and mature fruits are highly appreciated and consumed. Since there is a lack of knowledge of the seed physiology of this species, we describe here the germination behavior and morphometry of seeds of Alibertia patinoi, and relate them to its ha...

ECOPHYSIOLOGY OF THE AVOCADO (Persea americana Mill.) TREE AS A BASIS FOR PRE-HARVEST MANAGEMENT

In spite of selection for thousands of years, the avocado is still a poorly domesticated tree in the early stages of adaptation to an orchard environment. Cultivars based on Guatemalan and Mexican germplasm, for the subtropics and Mediterranean climates, have only been available since the 1920's, and even in the best growing conditions the yield barrier of 30 t·ha is hard to breach. Tropical “W...

Geographic and Genetic Population Differentiation of the Amazonian Chocolate Tree (Theobroma cacao L)

Numerous collecting expeditions of Theobroma cacao L. germplasm have been undertaken in Latin-America. However, most of this germplasm has not contributed to cacao improvement because its relationship to cultivated selections was poorly understood. Germplasm labeling errors have impeded breeding and confounded the interpretation of diversity analyses. To improve the understanding of the origin,...
