Iodine is a non-essential element for land plants, but considered as beneficial element, related to antioxidant capacity, environmental adaptations and improvement of plant growth. Salinity one the more recurrent abiotic stresses worldwide, seriously affecting vegetal production. The aim this work was evaluate iodine application (Q products® KIO3, Quimcasa de México, Naucalpan, Mexico) in straw...

salicylic acid (sa) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. the physiological mechanism of exogenous sa to affect the senescence of cut lisianthus flowers during vase life was investigated. fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mm sa and then held at 25◦c up to 12 days. ...

BACKGROUND: The active oxygen species, despite the damaging effects they have useful roles in the body are living things. OBJECTIVES: This research was done to determine whether Reactive Oxygen Species (ROS) could mediate Cyanide and Methylviologen signal in seed dormancy alleviation and sunflower seed germination, more widely, to assess their putative ro...

Callus cultures initiated from red beet tubers were acclimated to 75 or 100 mM NaCl salinity by exposing them gradually increasing concentrations. The callus lines displayed growth rates comparable the control culture cultivated on NaCl-free medium. Several antioxidant system components analyzed assess role of defense in callus’s ability proliferate salt-supplemented media. It was found that pr...

In order to study the heritability and genetic parameters of antioxidant activity in barely (Hordeum vulgare L.) under salinity stress, a seven-parent half diallel (F1 crosses + parents) was conducted non-stress salt stress (8 12 dS m-1) conditions greenhouse, during 2016-17, Ardabil, Iran. this experiment, enzymes ascorbate peroxidase (APX), catalase (CAT) superoxide dismutase (SOD) were measu...

Soil contamination by toxic trace metal elements, like barium (Ba), may stimulate various undesirable changes in the metabolic activity of plants. The plant responses are fast and with, direct or indirect, generation reactive oxygen species (ROS). To cope with stress imposed ROS production, plants developed a dual cellular system composed enzymatic non-enzymatic players that convert ROS, their ...

Water stress may affect the growth, physiology, morphology, biochemistry, and productivity of Nigella sativa (black cumin), a medicinal aromatic plant. Measuring these parameters under various irrigation regimes could provide useful information for successful genotype selection breeding. Therefore, agronomically significant features were evaluated in ten black cumin genotypes (Afghanistan, Paki...

Salinity and alkalinity stresses are common in arid semiarid climates. Both these not only retard crop growth but also cause a severe reduction yields. The present experiment was performed to investigate the morphological, physiological, biochemical, genetic responses of two maize hybrids (FH-1231 DK-6714) salinity stresses. treatments were comprised salt stress (NaCl:Na2SO4 at 9:1 ratio), alka...

The present study investigates the effect of soil amended with sewage sludge on oxidative changes in zucchini and cucumber plants (Cucurbitaceae) and the consequent activation of their antioxidative systems and detoxification mechanisms. The plants were grown in pots containing soil amended with three concentrations of sewage sludge (1.8 g, 5.4 g and 10.8 g per pot), while controls were potted ...
