Chile is considered to be a sub-center of origin for the cultivated potato, with native and introduced genetic material coexisting in the country. Thus, the different varieties present in Chiloe Island are characterized by a rich diversity of forms, sizes, colours and phenological characteristics...

The objective of the investigation was to evaluate the in-vitro multiplication of two varieties of blueberry (Vaccinium corymbosum L.), 'Brigitta' and 'Legacy' in response to five explants densities (5, 10, 15, 20 and 25) and four flask volumes (10, 20, 30 and 40 mL) for cultivation. For both var...

The present paper aims to determine the nutritional contribution of pollen from four cultivated species (Malus domestica Borkh., Eucalyptus globulus Labill., Brassica napus L. ssp. oleifera and Vaccinium corymbosum L.) pollinated by bees (Apis mellifera L.) in Southern Chile. The pollen was colle...

In cereals cultivated in Southern Chilean Andosols, arbuscular mycorrhizal (AM) fungi may play a main role for phosphorus (P) uptake. Because P acquisition at early growth stages is crucial for cereals, we investigated the development of indigenous AM during the first 45 days after planting of tw...

Up until a few years ago, the microsporidian parasite Nosema ceranae was considered to be a pathogen of Apis cerana exclusively; however, only recently it has shown to be very virulent to Apis mellifera. Therefore, it has been named as apathogenic agent active in the disappearance of honey bee co...
