The influence of plant interference and a mild drought on gas exchange and oxidative stress was investigated using potted plants of two cotton species (Gossypium hirsutum L. cv. Delta Pine 5415, and Gossypium barbadense L. cv. Pima S-7) and spurred anoda (Anoda cristata L. Schlecht.) of the Malvaceae. Without interference, cotton and spurred anoda had similar net photosynthesis (Pnet) but diffe...

The objective of current study was to determine the effects of non-thermal atmospheric plasma (NTAP) on physiological features of Black Cumin seeds. Black Cumin seeds were divided into 4 groups: one control group and three experimental groups. The experimental groups were exposed to NTAP for 5, 10 and 20 minutes, respectively. Then the seeds of the experimental and control groups grew for 21 da...

 The effect of sodium silicate (Si) and potassium (K) were investigated on the major antioxidant enzyme activities in two different grapevine cultivars (Vitis vinifera L., cvs Yezandai and Malinger Ramfi) under drought stress. The traits included superoxide dismutase (SOD, EC 1.15.1.1), catalase (CAT, EC 1.11.1.6), peroxidase (POD, EC 1.11.1.7), guaiacol peroxidase (GPX, EC 1.11.1.7), ascorbate...

In this study, the effects of Funelliformis mosseae and Piriformospora indica on wheat growth, enzyme activity and gene expression of catalase (CAT), ascorbate peroxidase (APX) and glutathione S-transferase (GST) in wheat leaves under different cadmium (Cd) toxicity were investigated. Cd exposure reduced plant dry mass and enzyme activities of CAT and APX, but it increased GST activity. The pre...

Cadmium (Cd) brings a devastating health hazard to human being as a serious consequence of agricultural and environmental contamination. We demonstrated the protective effect of silicon (Si) on cadmium (Cd)-stressed rapeseed (Brassica napus L. cv. BINA Sharisha 3) plants through regulation of antioxidant defense and glyoxalase systems. Twelve-day-old seedlings were exposed to Cd stress (0.5 and...

Benzoic acid (BA) and Cd exhibit cumulative effects on plants due to their accumulation in the soil. The present study reports the effects of BA an allelochemical, Cd and their combinations on seed germination, seedling growth, biochemical parameters, and response of antioxidant enzymes in Triticum aestivum L. The experiment was conducted in sand supplemented with Hoagland nutrient solution. Be...

This work evaluates the (cor-)relations between selected biochemical responses to toxic Cd and the degree of Cd sensitivity in a set of pea genotypes. Ten genotypes were analysed that differ in their growth response to Cd when expressed as root or shoot tolerance indices (TIs). Concentrations of non-protein thiols (NPTs) and malondialdehyde (MDA), activity of chitinase, peroxidase (POX), and ca...

The intensive global use of glyphosate has led to the evolution resistant (GR) weed species, including economically damaging horseweed (Conyza sumatrensis). We evaluated resistance mechanisms C. sumatrensis. While 5-enolpyruvylshikimate-3-phosphate synthase activity was similar between and nonresistant biotypes, plants from GR population accumulated lower shikimate levels than susceptible ones,...

Abstract Maturity is an important factor in regulating seed vigor, while inappropriate harvest date affects vigor seriously. Here we reported that the was highest among 25–28 days after pollination, and these were best time for sunflower seeds. Seed moisture content increased first then decreased, dry weight continuously with advancement of development. Oil protein are main nutriments mature se...
