Biochar, as a soil conditioner, has been widely used to promote the growth of maize, but most current research is short-term experiments, which limits on long-term effects biochar, especially physiological mechanism biochar maize in aeolian sandy still unclear. Here, we set up two groups pot respectively after new application and one-time seven years ago (CK: 0 t ha-1, C1: 15.75 C2: 31.50 C3: 63.00 C4: 126.00 ha-1), planted with maize. Subsequently, samples were collected at different periods explore effect physiology its after-effect. Results showed that plant height, biomass, yield highest rates increase rate ha-1 22.22% biomass 8.46% compared control under treatment. Meanwhile, height increased gradually treatment (increased by 4.13%-14.91% 13.83%-58.39% control). Interestingly, changes SPAD value (leaf greenness), soluble sugar protein contents leaves corresponded trend growth. Conversely, malondialdehyde (MDA), proline (PRO), catalase (CAT), peroxidase (POD) superoxide dismutase (SOD) manifested an opposite In conclusion, can inducing biochemical characteristics, excessive ranging from 63.00-126.00 inhibited After field aging, inhibitory amount disappeared changed promoting effect.

Drought stress (DS) is a potential abiotic that substantially reducing crop productivity across the globe. Likewise, salinity (SS) another serious also major threat to global productivity. The rapid climate change increased intensity of both stresses which pose food security; therefore, it urgently needed tackle ensure better production. Globally, different measures are being used improve under conditions. Among these measures, biochar (BC) has been widely soil health and promote yield application BC improves organic matter, structure, aggregate stability, water nutrient holding capacity, activity beneficial microbes fungi, leads an appreciable increase in tolerance damaging stresses. protects membrane uptake, maintains homeostasis, reduces reactive oxygen species production (ROS) through enhanced antioxidant activities, thereby improving Moreover, BC-mediated improvements properties photosynthetic activity, chlorophyll synthesis, gene expression, stress-responsive proteins, maintain osmolytes hormonal balance, turn against osmotic ionic In conclusion, could be promising amendment bring drought Therefore, present review, we have discussed various mechanisms salt tolerance. This review will help readers learn more about role causing plants, provide new suggestions on how this current knowledge can develop

Effects of Two Biochar Types on Mitigating Drought and Salt Stress in Tomato Seedlings

Agronomy, Год журнала: 2023, Номер 13(4), С. 1039 - 1039

Опубликована: Март 31, 2023

Biochar’s underlying biochemical and physiological mechanisms in reducing irrigation salinity stress are elusive. This paper investigates the effects of two types biochar (wood poultry biochar) on growth physiology tomato seedlings exposed to combined drought stress. Two biochar, wood (WB) (PB), were added soil separately, with three gradients 0, 100, 200 mmol/L water supply conditions full (FI) deficit (DI). Results showed that addition effectively improved root potential osmotic plant under Biochar application also mitigated leaf relative content by 9.86% 24.37% stress, respectively. Furthermore, decreased abscisic acid concentrations xylem sap altered structure increased field holding capacity, indirectly increasing supply. While use efficiency did not increase significantly after application, a synergistic seedling consumption occurred. In conclusion, shows promise for promoting help mitigate adverse impacts physiology.

Abstract Drought stress can have negative impacts on crop productivity. It triggers the accumulation of reactive oxygen species, which causes oxidative stress. Limited water and nutrient uptake under drought also decreases plant growth. Using cobalt fulvic acid with biochar in such scenarios effectively promote Cobalt (Co) is a component various enzymes co-enzymes. increase concentration flavonoids, total phenols, antioxidant (peroxidase, catalase, polyphenol oxidase) proline. Fulvic (FA), constituent soil organic matter, increases accessibility nutrients to plants. Biochar (BC) enhance moisture retention, uptake, productivity during That’s why current study explored influence Co, FA BC chili plants This involved 8 treatments, i.e., control, 4 g/L (4FA), 20 mg/L sulfate (20CoSO ), 4FA + 20CoSO , 0.50%MFWBC (0.50 MFWBC), 0.50MFWBC, 0.50MFWBC. Results showed that 0.50MFWBC caused an height (23.29%), dry weight (28.85%), fruit length (20.17%), girth (21.41%) yield (25.13%) compared control.

The present study was designed to highlight the ameliorative role of iron nanoparticles (FeNPs) against drought stress in spinach (Spinacia oleracea L.) plants. A pot experiment performed two-way completely randomize design with three replicates. For levels were used by maintaining field capacity soil. This included control (100% capacity), moderate (D1; 50% capacity) and severe (D2; 25% capacity). FeNPs synthesized green method using rice straw applied along precursor FeCl3, as Fe source for synthesis FeNPs, through foliar spray (40 mg L− 1 both). Growth parameters, efficiency photosynthetic machinery, gas exchange attributes, total soluble proteins, inorganic ions (Ca2+, K+ & Fe2+) significantly reduced at both D1 D2 levels, compared supplements form FeCl3 improved these attributes conditions. Malondialdehyde, H2O2, relative membrane permeability (stress indicators) activities antioxidants increased response stress. further antioxidant defense efficiently lowered effects indicators. These resulted growth S. plants Results showed that had more prominent on FeCl3. findings suggest could be a helpful tool lessening harmful consequences this can abiotic alleviation other crops well.
