Plant-growth-regulating phosphono peptides

1990

Phosphono peptides exhibited plant‐growth‐regulating activity when tested on Lepidium sativum and Cucumis sativus. The studies have provided evidence that the mechanism of action of these compounds may involve the uptake of the phosphono peptides into the plant, intracellular hydrolysis of the peptide bond and release of the P‐terminal aminoalkylphosphonic acid. This acid or its metabolite is then probably responsible for the observed physiological effect.

The impact of copper ions on oxidative stress in garden cress Lepidium sativum

2017

Normal oxygen metabolism is an endogenous source of reactive oxygen species (ROS). The source of ROS are also many environmental factors including heavy metals. In certain concentration range, the presence of ROS is necessary to maintain proper cell function. Thus, cells have many mechanisms, which role is focused on maintaining a constant concentration of ROS. Imbalance between the formation of ROS and action of a protective antioxidant system leads to oxidative stress. This may results with a damage to the structure of proteins, lipids and nucleic acids, which in turn can lead to disturbances in the functioning of the cell and even to the death. The aim of the study was to evaluate the ef…

Oddziaływanie kadmu i kwasu salicylowego na aktywność metaboliczną Lepidium sativum L.

2016

Kadm (Cd) jest metalem ciężkim, który w wyniku działań człowieka stał się głównym zanieczyszczeniem środowiska. Charakteryzuje się wysoką toksycznością dla wszystkich organizmów żywych. Symptomem toksyczności kadmu dla roślin są przede wszystkim zmiany morfologiczne, ograniczenie procesów fotosyntezy oraz stres oksydacyjny. Efekt zwiększenia odporności na stres można uzyskać, stosując różne związki egzogenne. Do takich związków należy między innymi kwas salicylowy (SA). Celem niniejszej pracy jest ocena wpływu kwasu salicylowego na stres metaboliczny u pieprzycy siewnej Lepidium sativum wywołany wzrastającymi stężeniami kadmu. W liściach pieprzycy siewnej oznaczano ilości białka, chlorofilu…

Herbicidal activity of phosphonic, phosphinic, and phosphonous acid analogues of phenylglycine and phenylalanine

1995

A series of phosphonic, phosphinic, and phosphonous acid analogues of phenylglycine and phenylalanine was synthesized and tested as herbicides against Lepidium sativum and Cucumis sativus. Aminobenzylphosphonic acids exhibited notable herbicidal activity and thus represent a group of the most active herbicides found among aminophosphonic acids.
