The application of germination models in economic crop management makes them extremely useful for predicting seed germination. Hence, we examined the effect varying water potentials (Ψs; 0. - 0.3, 0.6, 0.9, 1.2 MPa) and temperatures (Ts; 20, 25, 30, 35, 40 °C) on maize enzymatic antioxidant mechanism. We observed that Ts Ψs significantly influenced percentage (GP) rate (GR), other parameters, including index (GRI), (GI), mean (MGI), time (MGT), coefficient velocity (CVG), energy (GE) (p ≤ 0.01). Maximum (87.60) minimum (55.20) hydro-time constant (θH) were reported at 35 °C 20 °C, respectively. In addition, base potential 50 percentiles was highest 30 (15.84 lowest (15.46 MPa). Furthermore, optimal, low, ceiling T (To, Tb Tc, respectively) determined as θT1 θT2 (0 (- 0.9 MPa), HTT has a higher value (R2 = 0.43 sub-optimal than supra-optimal 0.41 °C). Antioxidant enzymes, peroxidase (POD), catalase (CAT), superoxide dismutase (SOD), ascorbate (APX), glutathione (GPX), increased with decreasing Ψs. contrast, CAT POD but declined °C. APX GPX remained unchanged Thus, maintaining activity is protective mechanism against oxidative stress. A decline characteristics may result from diverting to anti-stress tools (antioxidant enzymes) necessary eliminating reactive oxygen species (ROS) reduce salinity-induced damage. parameters this study are easily applicable simulation Z. mays L. under extreme environmental conditions characterized by deficits temperature fluctuations.

Microplastics and Invasive Alien Plants: A Change in Soil Ecology Deliberately Impacts the Aboveground Productivity of the Crops

Journal of Soil Plant and Environment, Journal Year: 2024, Volume and Issue: 3(1), P. 1 - 7

Published: March 24, 2024

Plastic is considered an emerging agroecological pollutant while biological invasion has also become a global environmental issue. Therefore, the contamination of microplastics and occurrence Solidago canadensis L. in agroecosystem may be severe hazard to soil plant functioning, reducing yield perhaps indirectly harming human health. Microplastic adversely affects ecosystems terms carbon pools their turnover. Invasive plants compete with agronomic crops, have allelopathic effects by secreting allelochemicals, detrimental on productivity crops. However, interaction had significant negative as well crop's physiological biochemical properties. Thus, interactive response created big gap how they raise concerns about crop potential entering into food web that ultimately

The more microplastic types pollute the soil, the stronger the growth suppression of invasive alien and native plants

Abstract The ecological consequences of microplastic pollution for plants remain largely unknown, and the few studies that tested effects usually focused on a single type plant species. However, most will be exposed to multiple types simultaneously, may vary among To test diversity plants, we grew eight invasive native species in pots with substrate polluted 0, 1, 3 6 microplastics.

Microplastics increase cadmium absorption and impair nutrient uptake and growth in red amaranth (Amaranthus tricolor L.) in the presence of cadmium and biochar

Abstract Microplastic (MP) pollution in terrestrial ecosystems is gaining attention, but there limited research on its effects leafy vegetables when combined with heavy metals. This study examines the impact of three MP types—polyethylene (PE), polyethylene terephthalate (PET), and polystyrene (PS)—at concentrations 0.02, 0.05, 0.1% w/w, along cadmium (Cd) biochar (B), germination, growth, nutrient absorption, metal uptake red amaranth ( Amaranthus tricolor L.). We found that different types did not negatively affect germination parameters like rate, relative vigor, speed. However, they increased phytotoxicity decreased stress tolerance compared to an untreated control (CK1). The presence MPs, particularly PS type, reduced phosphorus potassium while enhancing Cd uptake. For example, treatments 0.02 CdB, 0.05 0.1 CdB content A. seedlings by 158%, 126%, 44%, respectively, treatment (CK2). Additionally, contamination led plant height, leaf dry matter content, fresh weights, indicating adverse growth. Moreover, MPs bioconcentration factors translocation for Cd, suggesting might act as carriers absorption plants. On positive side, addition improved several root parameters, including length, volume, surface area, number tips potential benefits Our shows combination reduces growth increases risk food crops.
