BACKGROUND The distribution of Palmer's oak (Quercus palmeri Engelm.) includes numerous isolated populations that are presumably relicts of a formerly larger range that has contracted due to spreading aridity following the end of the Pleistocene. PRINCIPAL FINDINGS We investigated a recently discovered disjunct population of Palmer's oak in the Jurupa Mountains of Riverside County, California...

The first host plant record for Anastrepha fumipennis Lima (Diptera: Tephritidae) in Geissospermum laeve (Vell.) Baill (Apocynaceae) and for A. nascimentoi Zucchi found in Cathedra bahiensis Sleumer (Olacaceae) was determined in a host plant survey of fruit flies undertaken at the "Reserva Natural da Companhia Vale do Rio Doce". This reserve is located in an Atlantic Rain Forest remnant area, i...

abstract to study the effects of xenia and methaxenia on the pistachio nut, 4 male genotypes from among all male genotypes provided by rafsanjan pistachio research institute were selected. the flowering period of the chosen genotypes was the same as 3 female cultivars of kalleghoochi, ohadi, and ahmadaghaii. by using split plot in the form of completely randomized blocks design, we conducted va...

The fruit hull of Garcinia mangostana Linn (Guttiferae) is used as an anti-inflammatory drug in Southeast Asia. Two xanthones, alpha- and gamma-mangostins, were isolated from the fruit hull of G. mangostana, and both significantly inhibited nitric oxide (NO) and PGE(2) production from lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. The IC(50) values for the inhibition of NO production by a...

Flowering plant density can increase number of visits and fruit set in multi-flowering plants, however this aspect has not been studied on few flower species. We studied the effects of individual floral display and plant density on the fruit production of the epiphytic, moth-pollinated orchid, Ryncholaelia glauca, in an oak forest of Chavarrillo, Veracruz, Mexico. Species is non-autogamous, and...

BACKGROUND: The formation and accumulation of advanced glycation end-products (AGEs) are implicated in several chronic human illnesses including type-2 diabetes, renal failure, and neurodegenerative diseases. The cranberry (Vaccinium macrocarpon) fruit has been previously reported to show anti-AGEs effects, attributed primarily to its phenolic constituents. However, there is lack of similar dat...

In a previous study (26) of changes in chemical composition of tung fruit from June 28 through November 29, 1940, it was shown that oil, sucrose, and protein accumulated in tung kernels and that starch and reducing sugar disappeared towards the end of this period. Appreciable quantities of nitrogen and carbohydrates disappeared from the hull as the fruits approached maturity and probably were i...
