The Effect Of Aluminium On Oxidative Stress-Related Enzyme Activity In Two Clover Species, Fayza A. Faheed Jan 2008

The Effect Of Aluminium On Oxidative Stress-Related Enzyme Activity In Two Clover Species, Fayza A. Faheed

Turkish Journal of Botany

The impact of aluminium (Al) stress on the production of hydrogen peroxide and on the activity of antioxidant enzymes involved in oxidative metabolism, such as ascorbate peroxidase (APX), peroxidase (POD), and catalase (CAT), were studied in seedlings of 2 clover species (Trifolium alexandrinum L. and Medicago sativa L.). A uniform decrease in germination and root elongation were detected as the primary signs of Al injury. A significant increase in hydrogen peroxide content was also related to an increase in Al uptake by the roots of the 2 clover species, especially at relatively highly toxic Al concentrations (2-6 mM) for 7 …


The Effects Of Ultraviolet Radiation On The Contents Of Chlorophyll, Flavonoid, Anthocyanin And Proline In Capsicum Annuum L., Kobra Mahdavian, M. Ghorbanli, Khosrow Manochehri Kalantari Jan 2008

The Effects Of Ultraviolet Radiation On The Contents Of Chlorophyll, Flavonoid, Anthocyanin And Proline In Capsicum Annuum L., Kobra Mahdavian, M. Ghorbanli, Khosrow Manochehri Kalantari

Turkish Journal of Botany

Although ultraviolet radiation is potentially harmful, it is an important component of terrestrial radiation to which plants have been exposed since invading land. Since then, plants have evolved mechanisms to avoid and repair UV radiation damage. Therefore, it is not surprising that photomorphogenic responses to UV-B and UV-C are often assumed to be adaptations to harmful radiation. Most of the compounds accumulated are directly involved in UV-B and UV-C protection: they are either efficient in filtering excess radiation or in scavenging radicals. In this study plants were grown for 5 weeks in controlled environment room. The plants were grown in …
