Environmental conditions and plant physiology modulate Cu phytotoxicity in field-contaminated soils

open access: yesEcotoxicology and Environmental Safety, 2022
Foliar Cu concentration has been widely used as a biomarker of plant growth in phytotoxicity bioassays. This relation has helped find plant processes altered by Cu in dose-response experiments (a bivariate approach).

Heavy metal induced stress on wheat: phytotoxicity and microbiological management

open access: yesRSC Advances, 2020
Among many soil problems, heavy metal accumulation is one of the major agronomic challenges that has seriously threatened food safety. Due to these problems, soil biologists/agronomists in recent times have also raised concerns over heavy metal pollution,

Phytotoxic Activity and Identification of Phytotoxic Substances from Schumannianthus dichotomus [PDF]

open access: yesPlants, 2020
The phytotoxic potential of plants and their constituents against other plants is being increasingly investigated as a possible alternative to synthetic herbicides to control weeds in crop fields. In this study, we explored the phytotoxicity and phytotoxic substances of Schumannianthus dichotomus, a perennial wetland shrub native to Bangladesh, India ...

Exploration of essential oils as alternatives to conventional fungicides in lupin cultivation [PDF]

open access: yes, 2018
Lupin (Lupinus L.) has the potential to become a true alternative for soybean as protein source, especially in the more temperate regions in the world. However, diseases such as anthracnose (Colletotrichum lupini), gray mold (Botrytis cinerea), and root ...

Effect of arsenic-phosphorus interaction on arsenic-induced oxidative stress in chickpea plants [PDF]

open access: yes, 2009
Arsenic-induced oxidative stress in chickpea was investigated under glasshouse conditions in response to application of arsenic and phosphorus. Three levels of arsenic (0, 30 and 60 mg kg−1) and four levels of P (50, 100, 200, and 400 mg kg−1) were ...
