Journal of Pollination Ecology, 2014 Understanding the interaction between reward-seeking flower feeding animals and plants requires consideration of the dynamic nature of nectar secretion. Studies on several plants suggest that nectar secretion may increase in response to its removal, but ...

Nectar-Secreting and Nectarless Epidendrum: Structure of the Inner Floral Spur [PDF]
Frontiers in Plant Science, 2018 Epidendrum, the largest genus of Neotropical orchids, contains both nectar-secreting and nectarless species. Here, we compare the fine structure of the inner floral spur, termed the cuniculus, in nectariferous (E. difforme, E. nocturnum,E. porpax, E. rigidum, E. vesicatum) and seemingly nectarless (E. capricornu, E. ciliare, E.

Nectary Structure and Nectar Secretion Characteristics Among Various Cultivars of Paeonia lactiflora
PlantsBackground: Paeonia lactiflora Pall. produces substantial quantities of nectar during the bud stage. In the production of cut flowers, this nectar attracts contaminants that compromise the quality of the flowers.

Nectar Production in Abutilon III. Sugar Secretion [PDF]
Australian Journal of Biological Sciences, 1971 Analysis of Abutilon nectaries shows that the sugar content of the nectary rises sharply as nectar secretion begins. Nectar secretion on the plant occurs at a steady rate of 2-5 mg total sugar per flower. hour for 36-48 hr. A total of about 100 mg sugar per flower is secreted, and this is about seven times the maximum sugar content of the nectary at ...

Kin discrimination in plants: overview and implications for population and community ecology
Biological Reviews, EarlyView.ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...

Flowering, nectar production and insects visits in two cultivars of Cucurbita maxima Duch. flowers
Acta Agrobotanica, 2012 The study was conducted on experimental plots in the conditions of Lublin. In the years 1998-2000 flowering, nectar secretion and insect visitation of male and female flowers of two winter squash (Cucurbita maxima Duch.) cultivars: 'Ambar' and 'Amazonka',
