An experiment was conducted under controlled conditions to study the effect of water extract of leaves, shoots and roots of either Sisymbrium irio L. =SISIR and/or Descurainia sophia (L.) Schur =DESSO on the germination and primary growth of wheat. A split-split plot experiment in CRD with three replications was used. The main plots were the type of weed: i.e. SISIR and DESSO and the sub-plots ...

Understanding spatial and temporal variation in factors influencing plant regeneration is critical to predicting plant population growth. We experimentally evaluated seed limitation, insect herbivory, and their interaction in the regeneration and density of tall thistle (Cirsium altissimum) across a topographic ecosystem productivity gradient in tallgrass prairie over two years. On ridges and i...

The discovery of antibiotics initiated the era drug innovation and implementation for human animal health. Very soon, antibiotic resistance started evolving due to over-prescription heavy usage drugs leading deleterious side effects. However, using plant extracts or medicinal plants has emerged as a new approach dealing with current problem. One such Sisymbrium irio L. is widely used in Unani t...

Industrial activities are associated with various heavy metals (HMs) being emitted into the environment, which may pose a threat to humans and animals. The rapid increase in an industrial activity major cities Saudi Arabia (SA) has raised concerns regarding accumulation of HMs environment. aim this study is assess soil native plants We collected 36 surface samples 12 plant species from sites ci...

The Romanian hamster Mesocricetus newtoni is endemic to South-Eastern Romania (Dobruja region) and North-Eastern Bulgaria, prefers steppic, arid, uncultivated habitats, but also found in alfalfa fields, less often corn cultures field-protecting vegetation belts. Previous studies provide only limited data regarding the diet of this cryptic species. one family group (one female four pups) was mon...

Abstract Recent studies have shown that green synthesis of silver nanoparticles (AgNPs) and their application in the control phytopathogenic fungi is a burgeoning field. Sisymbrium irio (Si) (London rocket) well-known weed grows abundantly Saudi Arabia from February to May. The present study concerned with rapid aqueous seed extract Si) presence sunlight. biosynthesized Si-AgNPs were characteri...

Polarized cell elongation is triggered by small molecule cues during development of diverse organisms. During plant reproduction, pollen interactions with the stigma result in the polar outgrowth of a pollen tube, which delivers sperm cells to the female gametophyte to effect double fertilization. In many plants, pistils stimulate pollen germination. However, in Arabidopsis, the effect of pisti...

Red light (R) has a dual effect on the seed germination of the two related species Arabidopsis thaliana and Sisymbrium officinale. The two species provide different means to separate the light-effects. In S. officinale, stimulation of germination by R depends on the stimultaneous presence of nitrate (light-effect I). The effect of both factors is completely blocked by tetcyclacis, an inhibitor ...
