In the present paper, we investigated the effects of afforestation on nitrogen fractions and microbial communities. A total of 24 soil samples were collected from farmland (FL) and three afforested lands, namely Robinia pseudoacacia L (RP), Caragana korshinskii Kom (CK), and abandoned land (AL), which have been arable for the past 40 years. Quantitative PCR and Illumina sequencing of 16S rRNA g...

This paper is aiming at designing a novel jujube transplanter with mechanic arms, which can support the sapling for a while when other operations is going on. It improves uniformity and stability. Pro-E software has been used for the design process, by which transplanting process has been analyzed and simulated.

HIGHLIGHTS Qualea grandiflocompounds with proven therapeutic properties; Hydroalcoholic extract of the leaves grandiflora increase expression MMP-14 and HIF-1α.

Seed oils of Passiflora edulis, Jatropa curucas, Tinospora cordifolia, Sesbania grandiflora and Sapindus laurifolia were investigated for their antihelmintic property against Pheritima pasthuma. Three concentrations (10, 50 and 100 mg/ml) of each oil were studied in the bioassay, which involved the determination of time of paralysis and time of death of the worm. Sesbania grandiflora showed the...

Calliandra grandiflora has been used as a medicinal plant for thousands of years in Mexico. Rhizobial strains were obtained from root nodules of C. grandiflora collected from different geographical regions in Chiapas and characterized by BOX-PCR, amplified rDNA restriction analysis (ARDRA) and 16S rRNA gene sequence analysis. Most isolates corresponded to members of the genus Rhizobium and thos...

Environmental tolerance of a species has been shown to correlate positively with its geographical range. On the Ordos Plateau, three Caragana species are distributed sequentially along the precipitation gradient. We hypothesized that this geographical distribution pattern is related to environmental tolerances of the three Caragana species during seed germination and seedling emergence stages. ...
