Fine roots (φ ≤ 2 mm) play an important role in the process of material and nutrient cycling forest ecosystems, but effect tree species diversity on functional characteristics fine is unclear. In this study, 1−7 subtropical communities with different richness were selected to study morphological characteristics, productivity (PRO), turnover rate (TUR) by continuous soil core extraction, ingrowt...

Seed dispersal by birds is critical for regeneration and maintenance of plant populations. Birds likely rely on both visible light human’s eyes ultraviolet (UV) reflectance when foraging fruit. Fruit color suggested to be an honest signal that allows assess nutrient status. We assessed UV pericarp as indicators fruit maturity in three fruiting shrubs Osaka, Japan. measured sugar content spectra...

The objective of this study was to understand the different morpho-physiological strategies of Ligustrum lucidum, an invasive species occurring in Brazilian forest fragments under heterogeneous light conditions. Ten individuals of L. lucidum were selected and evaluated for morphological of the leaves and physiological traits. For morphological parameters were evaluated: length, width, area, ang...

Oleanolic acid and ursolic acid are the main bioactive compounds in fruit of Ligustrum lucidum Ait, which possess anti-inflammatory, antioxidative, antiprotozoal, antimutagenic and anticancer properties. In this study, the ultrasound-assisted extraction of oleanolic acid and ursolic acid from L. lucidum Ait was investigated with HPLC-photodiode array detection. Effects of several experimental p...

El objetivo fue conocer la estructura, diversidad y los servicios ecosistémicos del arbolado en cuatro parques de ciudad Texcoco Mora, Estado México. Se realizó un censo análisis árboles existentes las áreas verdes seleccionadas. determinó una población arbórea compuesta por 391 individuos, pertenecientes a 19 familias 34 especies. Los taxones más comunes fueron Ficus benjamina (23 %), Schinus ...

The Thiobarbituric Acid (TBA) reactive substances assay is an easy and quick assay for the assessment in plants of lipid peroxidation, in which Malondialdehyde (MDA) is derivatized. To analyze the applicability of this method, the MDA concentrations in the leaves of different plants were measured by the TBA method. To further separate the interfering substances, fractional extraction and Gas Ch...

Unlike landmark methods for estimating object asymmetry, continuous symmetry measures (CSM) can be used to measure the symmetry distance (ds) of inconsistent objects, such as plant leaves. Inconsistent objects have no homologous landmarks, no consistent topology, no quantitative consistency, and sometimes no matching points. When CSM is used in conjugation with LAMINA Leaf Shape Determination s...

Fruits are a rich source of antioxidants and traditional Chinese fruits have been studied for their chemopreventive and chemotherapeutic properties against cancers and other diseases. The total phenol and flavonoid contents of eleven Chinese fruits extracts were determined. Total phenolic and flavonoid contents were estimated by both the Folin-Ciocalteau and aluminium chloride methods. The anti...

performed with the program SPSS14. Results: We obtained a total of 519 patients with positive skin prick test between January 2009 and March 2011. This group comprised 47% females and 53% male, with a mean age of 19 years between 3 to 79 years. We have 253patients with allergic rhinitis (AR) and asthma (A), 173 with RA and 93 with A. 55% of the patients reacted to one allergen extract (AE) and ...
