Imidazolinone herbicides used today in the irrigated rice Clearfield[R] system are persistent in soil, and their phytotoxic
effects can be observed up to two years after application.
compounds are generally emancipated in surrounding environments as volatiles from leaves, leachates from aerial parts mostly leaves through rain, downward stem flow, exudates from roots and decomposition of plant residues .
Phenolic contents increased with stage of development of wheat, and residue of wheat cultivars AARI-2011 and Lasani-2008 collected and soil incorporated at anthesis and maturity were more phytotoxic
than of Millat-2011 and Faisalabad-2008.
Thus, this study aims to evaluate the phytotoxic
potential of hexane, ethyl acetate and aqueous extracts of young leaves of Blepharocalyx salicifolius (Kunth) O.
substances in root exudates of cucumber (Cucumis sativus L).
1] (Figure 7); above this concentration, the probable phytotoxic
effect of the auxins was prejudicial to promoting greater root formation.
Climate changes have brought about the extinction of some species, thus neglecting the possibility to learn about their metabolites with phytotoxic
While water supply is undisputedly the major factor that determines crop growth, characteristic soil attributes of the region, such as high salinity, sodicity, acidity, and phytotoxic
concentrations of chloride ([Cl.
A Zn/ Cd ratio less than 100 in soils contaminated by mine wastes and most other sources of Cd and Zn causes Zn hyperaccumulation to reach phytotoxic
levels and limit yields of most plant species before much Cd can be accumulated.
This compound is also mentioned phytotoxic
0, it is solubilized into a phytotoxic
form, mainly as [Al.
Ruta species are sources of diverse classes of natural products such as flavonoids, alkaloids, essential oils, coumarins, phenols, saponins lignans, and triterpenes, with biological activities including antifungal, antioxidant, phytotoxic
, abortive, depressant, antidotal and anti-inflammatory (Mohhr, 1982; Juan, 1984; Raghav et al, 2006; Kuzovkina et al.
