Previous investigations have shown that CY4-labeled transcinnamic acid is rapidly converted to o-coumaric acid P-glucoside by shoots of Melilotus alba (white sweet clover) (1) and Hierochlod odorata (sweet grass) (2). This glucoside is then converted to coumarin (l-3), possibly by way of trans-cis isomerization of the glucoside to coumarinic acid P-glucoside. The small amount of radioactivity f...

In this paper, a possible use of white sweet clover (Melilotus albus Med.) for phytoremediation was assessed. The plants were grown on soils with naturally occurring concentrations potentially toxic elements (PTEs). First, the content PTEs determined in plant biomass and soil samples using: (a) Optical emission spectrometry inductively coupled plasma to determine Sb, As, Cd, Cu, Ni, Pb, Se, (b)...

Cover crops (CC) have great potential to enhance the sustainability of agroecosystems. However, wide range possible rotations CC and cash (CaC) means that important knowledge gaps persist on how affects CaC. We investigated legacy effects five common (three monocultures: vetch, melilotus, barley, two mixtures: barley-vetch barley-melilotus) most CaC, maize wheat. A microcosm, semi-controlled ex...

The present study aimed to investigate the effect of two type of soil (clay and sandy soils) in the potential allelopathic effects of Artemisia herba-alba, Oudneya africana crude powder (0, 1, 3 and 6%) on some growth parameters of two weeds (Bromus tectorum and Melilotus indica) under laboratory conditions (pot experiment). The experimental findings have reported that the donor species crude p...

A combination of flooding and salinity is detrimental to most plants. We studied tolerance of complete submergence in saline water for Melilotus siculus, an annual legume with superhydrophobic leaf surfaces that retain gas films when under water. M. siculus survived complete submergence of 1 week at low salinity (up to 50 mol m(-3) NaCl), but did not recover following de-submergence from 100 mo...

background and purpose: during recent years, nitric oxide (no) has been considered as a molecule involved in migraine headaches. this free radical involves in initiation of migraine headaches via no/cgmp signaling pathway and vascular relaxation specially big intracranial arteries. therefore, we studied the effects of aqueous extract of origanum vulgare and melilotus officinalis prescribed in m...

Effects of temperatures on the host-parasite relationships were studied for three legume species and four populations of root-knot nematodes from the western United States. The nematode populations were Meloidogyne hapla from California (MHCA), Utah (MHUT), and Wyoming (MHWY), and a population of M. chitwoodi from Utah (MCUT). The legumes were milkvetch (Astragalus cicer), alfalfa (Medicago sat...
