The bioactivities of boxthron fruits, a source of oriental medicine, are well known, whereas phytochemical studies of the boxthorn stem are rare. In this study, the stem extract of boxthorn (Lycium chinense Miller) and its subfractions were evaluated for their effects on nitric oxide (NO) inhibition and procollagen type I peptide (PIP) synthesis. A phenolic amide isolated from the stem extract ...

Potassium in plants accounts for up to 10% dry weight, and participates in different physiological processes. Under drought stress, plant requires more potassium but potassium availability in soil solutes is lowered by decreased soil water content. Forming symbiosis with arbuscular mycorrhizal (AM) fungi not only enlarges exploration range of plant for mineral nutrients and water in soil, but a...

Species that occupy the same area and use the same resources must either compete with each other or find ways to minimize competition. For rodents, 1 important resource is nesting sites. In this study I present data from direct behavioral observations in the succulent karoo of South Africa that show aggressive interactions between bush karoo rats (Otomys unisulcatus) and striped mice (Rhabdomys...

The root restriction of protected cultivation has been widely used to increase productivity and sustainability in modern agriculture. However, there have few studies wolfberry (Lycium barbarum) restriction, it is cultivated mostly by clean tillage. In this study, we measured the growth Lycium barbarum composition diversity bacterial community soil properties L. under different methods with rest...

The purpose of the present study was to investigate the effects of Lycium barbarum polysaccharides (LBP) on exercise-induced oxidative stress in rats. Rats were divided into four groups, i.e., one control group and three LBP treated groups. The animals received an oral administration of physiological saline or LBP (100, 200 and 400 mg/kg body weight) for 28 days. On the day of the exercise test...

Purpose. The objective of this study was to evaluate the morphological parameters Lycium spp. seeds from collections in M. Hryshko National Botanical Garden (NBS) NAS Ukraine. Methods. Cultivars and varieties three species (Lycium barbarum, L. chinense, truncatum) were studied period 2016 till 2019. following morphometric measurments conducted: weight, length, width index shape. Basic statistic...

Miller and Venable (1) claimed that polyploidy is a “trigger of unrecognized importance” for the evolution of gender dimorphism, an idea originally proposed by Jennings (2) and Baker (3). In our opinion, their phylogenetic analysis of North American Lycium (Solanaceae) does not support the claimed associations between polyploidy, self-fertility, and gender dimorphism. There is no support (boots...
