Cyclopeptides from the Bark of Discaria americana

Journal of Natural Products, 2001
Two new cyclopeptides, named discarene C (1) and discarene D (2), have been isolated from the bark of Discaria americana, along with seven known cyclopeptide alkaloids. The structures of the new compounds were determined by spectroscopic methods, mainly NMR.

POTENTIAL OF DISCARIA AMERICANA FOR METAL STABILIZATION ON SOILS AMENDED WITH BIOSOLIDS AND ASH-SPIKED BIOSOLIDS

International Journal of Phytoremediation, 2009
Biosolids (B) may contain various types of environmental pollutants, which can exert phytotoxic effects in plants. The effect of aqueous extracts on seed germination and the primary root growth of discaria (Discaria americana) obtained from different soil-application rates of B and a mixture of B and incinerated B were investigated.

Effects of Zn2+ on nodulation and growth of a South American actinorhizal plant, Discaria americana (Rhamnaceae)

World Journal of Microbiology and Biotechnology, 2006
Discaria americana is a xerophytic shrub which lives in symbiosis with an actinomycete of the genus Frankia. The objective of this paper was to investigate the effects of high soil Zn2+ concentrations on growth and nodulation on the association Discaria americana–Frankia with the aim of determining if this association is suitable for improving ...

Reproductive phenology, pollination biology, and gynoecium development inDiscaria americana(Rhamnaceae)

New Zealand Journal of Botany, 1991
Abstract Discaria americana individuals bloom in late winter or early spring and display large numbers of small, white, entomophilous flowers for about a month. Individual flowers contribute to colour display for c. 4 weeks, although they are active in pollen transfer only 5-7 days (male phase = days 1-3, female phase = days 2-5).

Breeding system and maternal success of a perennial hermaphrodite,Discaria americana(Rhamnaceae)

New Zealand Journal of Botany, 1993
Abstract Various aspects of the reproductive biology of the perennial hermaphrodite D. americana were studied by combining data from both wild and garden-grown individuals from several years. Reproduction in this species is exclusively sexual and strictly xenogamous, with pollen transfer depending solely on insect vectors.
