“…nutritional content (e.g., sugar) of the nectar in their flowers. The finding that fewer than 10% of the samples studied may be classified as nonnative monofloral is consistent with the results reported by Horn and Aira (1997), who identified only one monofloral honey, which was derived from Trifolium repens, in the Los Lagos region of southern Chile.…”

“…Thus, weeds used by melliferous bees as a nectar source can be important in honey production, even though the flora surrounding apiaries is primarily native. Several authors (Horn and Aira, 1997;Montenegro et al, 2003;Ramírez andMontenegro, 2004, Forcone et al, 2005;Fagúndez and Caccavari, 2006;Montenegro and Fredes, 2008;Böke, 2013;Ciappini and Vitelleschi, 2013;Montenegro et al, 2013aMontenegro et al, , 2013b have reported the presence of certain pollen types from diverse species considered weeds in monofloral honeys made from the nectar of native species, and monofloral honeys made from the nectar of weeds have even been reported. Many weed species are also pollen sources, as has been shown by several authors (Montenegro et al, 1992;Montenegro et al, 1997;Forcone et al, 2011;Chamorro-García et al, 2013), but in this work, we analyzed only nectar sources.…”

The importance of weeds as melliferous flora in central Chile

in Chile has been demonstrated in many studies; however, certain species that are viewed as weeds contribute extensively to the floral composition of honey. A total of 92 honey samples from the Libertador General Bernardo O'Higgins region in Chile were analyzed to determine which weeds are most important in honey production and which are most preferred by melliferous bees. Their relative contributions to the pollen fraction of each honey sample were also determined using melissopalynological tests in accordance with Chilean regulation (NCh2981.Of2005; Ministerio de Agricultura. 2006) to evaluate the botanical origins of the honey samples. Species considered weeds were classified according to their importance in Chilean crops, as proposed by Matthei (1995), based on the classification system by Holm (1979). These authors categorize weeds on a scale that ranges from "very serious", if they potentially cause significant crop loss, to "occasionally present as weeds" if they are part of the national flora. A total of 19 weeds were identified at the species level from the pollen types found, and five weeds were identified at the genus level. The weeds were classified as contributing very frequently, frequently, rarely and occasionally to honey using the methodology described by Louveaux et al. (1970) for determining the frequency with which plant species contribute to honey based on the corresponding pollen types found in honey. Overall, 74% of the weeds used by Apis mellifera were European, and 53% of the weeds had perennial life cycles. The families that contributed the most to honey production were Fabaceae, Asteraceae and Brassicaceae. The importance of species viewed as weeds in the production of Chilean honey is discussed.

“…Based on pollen analyses of honeys from Temperate climate, other types of monofloral honeys are dominated by Sauce ( Salix-Eucryphia-Lotus ), Tineo ( Weinmannia-Salix-Eucryphia ), Rape ( Brassica spp. ), and White clover ( Trifolium repens ), while polyfloral honeys also contain pollen of these monofloral honeys, along with pollen of other plants (Horn and Aira, 1997). On the other hand, in Mediterranean climate, monofloral honey are also dominated by native flora, specially Quillay (Montenegro et al, 2009).…”

Drought severity has pervasive impacts on honey production via direct impacts on water resources and nectar availability. The current mega-drought in Chile has impacts on water resources and forest vigor, particularly in the Mediterranean and Temperate regions where honey production is concentrated. While honey production plays an important role in the local rural economy and providing pollination services to other agricultural activities, studies of the long-term impacts of the mega-drought on honey production are scarce. Here, we evaluate the impact of climate variability on historical changes in honey production in the Mediterranean (32°S–37°S) and Temperate (37°S–41°S) regions of Chile, using annual honey production records of beekeepers together with national records of honey exports. We also used questionnaires and interviews to evaluate beekeeper perceptions regarding the effects of climate change on honey production and adaptation practices in both regions. Results indicated a declining trend in honey production and exports in the last decade, largely related to changes in precipitation and temperature in both regions. Declines in honey production affected 82% of beekeepers, 80% of whom had employed adaptive measures, and 74% considered that these measures were effective. The drier, warmer Mediterranean region showed more severe declines in precipitation and honey production, which beekeepers reported as a main contributing factor to transhumance from the Mediterranean to the Temperate region. This is the first study to show the effects of drought on honey production in Chile, providing a foundation for future climate change adaptation strategies within apiculture.

“…Honeys also are analyzed for the pollen content and to control their origin. This kind of analysis has become more popular in recent years since the characterization of honey, one of the most highly valued apicultural products, is an important aspect with respect to beekeeping development (Horn & Aira, 1997).…”

Physicochemical properties of eight samples of Mexican honeys from the West region were measured over 23 parameters, including moisture, water activity, soluble solids, hydroxymethylfurfural (HMF), ash, electrical conductivity, acidity (free, lactonic, and total), sugar content (fructose and glucose), color (L*, a*, b*), and mineral content. In addition, honey samples were classified according to the pollen quantitative analysis. According to the physicochemical parameters studied, the samples showed the values typical of honey. All honey samples were classified as dark according to the values of the L* color parameter. Only two honey samples were classified as monofloral and six as multifloral type. In general, the honey samples presented a good level of quality because they meet the physicochemical specifications of international regulation.
