This paper gives an overview of the occurrence of mite pests (Schizotetranychus nanjingensis Ma & Yuan, Aponychus corpuzae Rimando and Aculus bambusae Kuang) and their damage to the moso bamboo (Phyllostachys pubescens) in Fujian province, China. The effects of mites on the physiology of the plants and their yield are briefly discussed. Possible causes of their outbreaks in bamboo forests are o...

In conventional in vitro culture, plantlets are kept closed containers to avoid contamination and drying of the explant. Ventilation inside improves plant growth affects secondary metabolism, as it modifies microenvironmental conditions. Therefore, objective this study was evaluate effect use ventilation systems on characteristics production photosynthetic pigments volatile organic compounds (V...

Estimation of the success ecosystem restoration through different methods is essential planning projects, especially nowadays when world community has declared target for an effective 25% degraded ecosystems in next years. In present study, we intro­duce results application two land preparation – soil ripping and terracing - on twenty years after actions. The study concerns reforested areas wit...

The taxonomy of the genus Stylophoronychus (Acari: Tetranychidae) is reviewed. The synonymy of Stylophoronychus Prasad, 1975 and Sinotetranychus Ma & Yuan, 1980 is accepted and the former has priority. As a result, the following new combinations are noted: Stylophoronychus guangzhouensis (Ma & Yuan) and Stylophoronychus insularis (Flechtmann). S. baghensis (Prasad) is newly recorded from the mo...

En esta investigación se obtuvo la enzima papaína a partir de látex tres especies del género Vasconcellea, V. chachapoyensis, heilbornii y pubescens, nativas región Amazonas en Perú. El extraído acondiciono con buffer acetato sodio, EDTA solución bisulfito sodio. La purificación realizó adaptando el método Andrade (2011), utilizó sulfato amonio para precipitación; etanol 96° dos etapas dilución...

A systematic study was conducted on P. pubescens by analyzing thermal characteristics of its rhizome and culm (1.5 m) at different ages, using various analyses such as X-ray diffraction (XRD), differential scanning calorimetry (DSC), and thermogravimetry (TG). For both the rhizome and culm of P. pubescens, the relative crystallinity (Cr) of cellulose increased and then appreciably decreased wit...

Flow cytometric measurements of nuclear DNA content were performed using ethidium bromide as the DNA stain (internal standard, Hordeum vulgare 'Ditta', 1C = 5.063 pg) in 25 samples belonging to nine diploid species and four varieties of Capsicum: C. chacoense, C. parvifolium, C. frutescens, C. chinense, C. annuum var. annuum, C. baccatum var. baccatum, C. baccatum var. pendulum, C. baccatum var...
