“…3840, Japan). The honey production potential per plant was calculated by multiplying the mean number of spikes per plant by the mean number of flowers/spike and then multiplying by mean nectar sugar/flower following the method described by Kim et al (2011). These data were used to estimate the honey production potential/plant and to further extrapolate the honey production potential/ha for each species.…”

A b s t r a c tThe aim of the current study was to determine the floral phenology, nectar secretion dynamics, and honey production potentials of two naturally growing lavender species (L. dentata and L. pubescens), in southwestern Saudi Arabia. In both species, flowering is continuous. This means that, when open flowers on a spike are shaded, new flowers emerge. Such a flowering pattern might be advantageous to the plant to minimise competition for pollinators and promote efficient resource allocation. The flowering periods of the two species overlap. Both species secreted increasing amounts of nectar from early morning to late afternoon. The mean maximum volumes of accumulated nectar from bagged flowers occurred at 15:00 for L. pubescens (0.50 ± 0.24 µL/flower) and at 18:00 for L. dentata (0.68 ± 0.19 µL/flower). The volume of the nectar that became available between two successive measurements (three-h intervals) varied from 0.04 µL/flower to 0.28 µL/flower for L. pubescens and from 0.04 µL/flower to 0.35 µL/ flower for L. dentata, This variation reflects the differences in the dynamics of nectar secretion by these species, and indicates the size of the nectar that may be available for flower visitors at given time intervals. The distribution of nectar secretions appears to be an adaptation of the species to reward pollinators for longer duration. Based on the mean amount of nectar sugar secreted by the plants, the honey production potentials of the species are estimated to be 4973.34 mg and 3463.41 mg honey/plant for L. dentata and L. pubescens, respectively.

“…ranges from 90 to 1200 kg honey/ha. Recently, Kim et al (2011) quantified the amount of nectar secreted per flower and per tree for Crataegus pinnatifida Bunge. The amount and dynamics of nectar secretion have been used, as well, to estimate the honey production potential of Ziziphus spina-christi (Nuru et al, 2012).…”

“…It was determined that there was a difference in the nectar volume by chestnut species. A previous study was reported that there was a significant difference in the nectar volume and sugar concentration between Korea hawthorn (1.4 μL, 27.2 Brix) and Chinese hawthorn varieties (3.6~5.4 μL, 11.3~12.6 Brix) [ 26 ]. The result of investigating the nectar properties of four varieties of the C. crenata showed that nectar volume (6.7~54.3 μL) and nectar concentration (18.2~57.1 Brix) displayed significant difference among the varieties, showing the same trend as in this study.…”

“…Because the dietary sugar consumed by bees affects the amount of honey available to humans through digestive physiology, sugar analysis is required for study of honey plants [ 26 , 27 ]. In this study, the sugar content (22.6~82.5 μg) and sugar content per catkin (0.43~1.35 mg/catkin) of floral nectar showed a significant difference ( Table 1 , p = 0.000).…”

Pollination is essential for efficient reproduction in pollinator-dependent crops that rely on the attraction of pollinators to flowers. Especially, floral nectar is considered to be an important factor attracting pollinator like honey bees, but differences among major chestnut species (Castanea crenata, C. mollissima, C. dentata, and C. sativa) are still little explored. This study aims to evaluate the value of honey source by analyzing floral nectar characteristics and comparing the composition of volatile organic compounds (VOCs) that mediate plant-pollinator interaction. In this study, we analyzed nectar samples obtained from male flowers using HPLC and HS-SPME/GC–MS. The five chestnuts showed significant differences between the volume of secreted nectar, free sugar composition, amino acid content and VOCs composition. Furthermore, C. crenata (Japanese cultivar ‘Ungi’) was revealed to emit the highest total amounts of VOCs and high levels of benzenoid compounds that are generally associated with flower-visiting insects. The sugar content per catkin, which is used to determine the honey yield, was the highest in C. crenata, suggesting that C. crenata ‘Ungi’ can be highly valued as a honey tree. Therefore, a better understanding of the relationship between pollinator and nectar characteristics of C. crenara could contribute to a prospective honey plant.

“…Honey was, however, not commonly used as a medicine in the medieval period, and was neglected with the rise of modern synthetic medicine, but in the last hundred years it has made a strong comeback, especially for its wound healing properties. Of the eight original research papers, in the first, Kim et al (2018) evaluate the characteristics of nectar produced by Korean and Chinese varieties of the hawthorn Crataegus pinnatifida, which may have potential as a major honey species. In the second paper, Venturieri, Leão, de Sousa Rêgo, and Venturieri (2018) discuss novel techniques to increase honey production from the Amazonian stingless bee Melipona fasciculata, which can easily be maintained in artificial hives.…”
