Additive Variance and Open‐Pollinated Progenies Under Mixed Mating

Plant Breeding, EarlyView.
ABSTRACT Open‐pollinated progeny tests are still widely interpreted as if all the individuals within a maternal family were true half‐sibs. However, in species with mixed mating systems, this assumption is often biologically unrealistic and may bias the estimation of the additive variance, narrow‐sense heritability and expected selection gains.

Rooting biostimulants for Coffea arabica L. cuttings

Coffee Science, 2020
In the rooting process of Arabica coffee cuttings, plant hormones are used for inducing root formation. However, synthetic molecules cannot be used to form organic seedlings. The objective of this work was to evaluate the effect Cyperus haspan extract and different concentrations and types of humic substances on Arabica coffee cuttings.

Small-scale Demucilager Machine for Arabica Coffee (Coffea arabica)

Journal of Engineering Research and Reports, 2022
Natural fermentation is time- and water-consuming, laborious, and causes weight loss in the coffee beans. It is the conventional method to remove coffee mucilage in the Philippines that can take up to 48 hours. This study aimed to develop a small-scale demucilager machine and evaluate its demucilaging capacity, demucilaging efficiency, product recovery,
