Geographic distribution, conservation, and genomic resources of cacao Theobroma cacao L

Crop Science, Volume 63, Issue 4, Page 1750-1778, July/August 2023., 2023
Abstract The cacao tree, Theobroma cacao L., is cultivated in the tropics, mainly in agroforestry systems, to produce seeds, the valuable raw material for the chocolate industry. Thus, the conservation and use of cacao genetic resources in breeding programs to increase yield and improve quality and disease resistance are vital for the global cacao ...

Microbiome resilience of Amazonian forests: Agroforest divergence to bacteria and secondary forest succession convergence to fungi

Global Change Biology, Volume 29, Issue 5, Page 1314-1327, March 2023., 2023
In Amazon, secondary succession is the natural process to recover the ecosystem after burning the forest. It begins with the recovery of plant biomass and the increased importance of fungal communities in the soil. Agroforestry is a proposed alternative to fire, attempting to mimic the forest with benefits such as increased biodiversity, soil fertility,

Pest categorisation of Maconellicoccus hirsutus

EFSA Journal, Volume 20, Issue 1, January 2022., 2022
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Maconellicoccus hirsutus (Hemiptera: Pseudococcidae), the pink hibiscus mealybug, for the EU. M. hirsutus is native to Southern Asia and has established in many countries in tropical and subtropical regions throughout the world.

The site of self-incompatibility action in cupuassu (Theobroma grandiflorum) [PDF]

Revista Brasileira de Botânica, 2005
Cupuassu (Theobroma grandiflorum (Willd. ex Spreng.) Schumann) is a fruit tree that is attracting attention in Brazil and also in other tropical countries. Its pulp is used to prepare ice-cream, juices, jellies and many other home-made sweets. This species has a very low fecundity, attributed to problems with pollination and self-incompatibility, noted

Determination of thermophysical properties of cupuassu (Theobroma grandiflorum) dry almonds

The Journal of Engineering and Exact Sciences, 2021
In comparison to cocoa, little has been reported on the drying of cupuassu almonds that can be used to produce cupulate, a chocolate type product. Thus, in this study thermophysical properties of cupuassu dry almonds (moisture = 9.68 % d.b.) were determined as: thermal conductivity (k) of 0.14 kW/(m.K), specific heat (cp) of 2.86 kJ/(kg.K), thermal ...

Status of Nitrogen in Different Parts of Cupuassu Tree in Oriental Amazon

Journal of Agricultural Studies, 2022
Despite the socio-economic importance of the cupuassu tree for the Amazon region, a few studies have aimed to evaluate the nutritional status of nitrogen in cupuassu plantations, especially in the different vegetative parts. Thus, this research aimed to quantify the content and accumulation of nitrogen in vegetative parts of two progenies of cupuassu ...

Leaf anatomical features of three Theobroma species (Malvaceae s.l.) native to the Brazilian Amazon [PDF]

Acta Amazonica, 2014
Theobroma species have economic importance due to their use in the cosmetic and food industries, mainly in the production of chocolate. However, the anatomy of their vegetative structures remains poorly studied. The goal of this study was to describe the
