Myrigalone A (MyA) is a rare flavonoid in fruit leachates of Myrica gale, a deciduous shrub adapted to flood-prone habitats. As a putative allelochemical it inhibits seed germination and seedling growth. Using Lepidium sativum as a model target species, experiments were conducted to investigate how environmental cues modulate MyA's interference with key processes of seed germination. Time cours...

Objective of the present study was to carry out the physicochemical and phytochemicals standardization of Lepidium sativum L seeds to establish the standard pharmacognostical parameters of this valuable medicinal plant. Many standardization parameters of Lepidium sativum were analyzed. Standard method was adopted for the preliminary phytochemicals screening. Analysis of pesticides residues, afl...

The hypolipidemic activity of Lepidium sativum (family: Brassicaceae) seed sapogenin and flavonoid extract (LSTS and LSTF) was studied against Triton x-100 and high cholesterol diet (HCD) induced hyperlipidemia on rats. The parameters assessed were serum total protein, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDLc), low density lipoprotein cholesterol (LD...

copper is a micronutrient which its, deficiency can alter essential functions in plant metabolism. on the other hand, excess copper is present in certain regions and environments, and can be potentially toxic to plants causing phytotoxicity by the formation of reactive oxygen species that damage cells. in this study, we examined the effect interactions between various concentrations of sodium n...

abstract there is a world-wide effort to reduce the amount of chemicals used in crop production by introducing modern biological and ecological methods. one possible alternative is allelopathy. a laboratory trial was carried out to investigate of alleopathic potential of angelica . in this study the effect of different concentrations of aqueous extract of angelica herb was investigated on seed ...

The micropylar endosperm cap covering the radicle in the mature seeds of most angiosperms acts as a constraint that regulates seed germination. Here, we report on a comparative seed biology study with the close Brassicaceae relatives Lepidium sativum and Arabidopsis thaliana showing that ethylene biosynthesis and signaling regulate seed germination by a mechanism that requires the coordinated a...

Many invasive species are too widespread to realistically eradicate. For such species, a viable management strategy is to slow the rate of spread. However, to be effective, this will require detailed spread data and an understanding of the influence of environmental conditions and landscape structure on invasion rates. We used a time series of remotely sensed distribution maps and a spatial sim...

The aim of the study was to use a battery of biotests composed of producers (Selenastrum capricornutum, Sorghum saccharatum, Lepidium sativum, and Sinapis alba), consumers (Thamnocephalus platyurus), and decomposers (Tetrahymena thermophila) to evaluate the toxicity of snowmelt and winter storm water samples. The toxicity of the samples collected in the winter period December to February (2010-...
