ULTRASTRUCTURE OF NECTARIES IN RELATION TO NECTAR SECRETION
American Journal of Botany, 1979In the last 15–20 years, ultrastructural studies have added new important cytological information to the relatively rich literature on the morphology and light microscopy of nectaries. On the basis of these studies, the following main conclusions can be drawn regarding the relation between the ultrastructure of nectaries and the process of nectar ...

Nectar secretion in excised flowers. VI. Relationship of secretion to protein metabolism
Canadian Journal of Botany, 1978The relationship of nectar secretion in snapdragon to protein metabolism, and the influence on both processes of indoleacetic acid (IAA) and to a lesser extent pollination, were both studied. Indoleacetic acid at 5 × 10−4 M appeared to initiate a reorganization in the nectary which led to the stimulation of growth and an early termination of secretion.

The timing of nectar secretion in staminal and staminodial glands in Lauraceae
Plant Biology, 2009AbstractThe flowers of many Lauraceae have two kinds of glandular organ: paired glands at the base of the filaments of the third androecial whorl, and staminodes with a glandular head, corresponding to a fourth, sterile androecial whorl. So far, it is unknown why there are two different kinds of organ with apparently the same function. Observations now

Effect of zinc on nectar secretion of Hibiscus rosa-sinensis L
Protoplasma, 2013Zinc toxicity in secretory cells caused a range of effects, mainly depending on metal concentration. Low concentrations activated nectary function increasing nectar secretion but secretion was greatly inhibited or stopped entirely by ongoing concentration.

Nectar secretion patterns in Salvia pratensis L. (Lamiaceae)
Flora, 1995Summary Nectar secretion patterns, volume, sugar amount, sugar concentration and sucrose/hexose-ratios in Salvia pratensis varied considerably between flowers of different plants, both during the course of a single day as well as over the whole anthesis, which lasted for 4 days.

Circadian rhythmicity of nectar secretion in Hoya carnosa
Botanica Helvetica, 2006Matile Ph. 2006. Circadian rhythmicity of nectar secretion in Hoya carnosa. Bot. Helv. 116: 1–7. A simple device for continuous sampling of nectar secreted in single flowers of Hoya carnosa R. Br. (Asclepiadaceae) is described. Sampling at 3 hrs intervals over several days revealed an oscillating secretion with maxima around midnight.
