Could buckwheat and spelt be alternatives to wheat under future environmental conditions? Study of their physiological response to drought

Agricultural Water Management, Journal Year: 2023, Volume and Issue: 278, P. 108176 - 108176

Drought is one of the most harmful abiotic stresses for plants. Future drought episodes are expected to increase, negatively affecting globally cultivated crops as wheat (Triticum aestivum). Together with crop dependency, future global food security at risk. Thus, finding alternative capable resisting essential ensure supply. Spelt spelta) and buckwheat (Fagopyrum esculentum) two underutilized crops, whose resistance mechanisms remain unknown. We hypothesize that both species will have avoidance characteristics a better response than wheat. grew wheat, spelt in greenhouse. treatment started 28 days after sowing. When reached 40 % field capacity (FC), was kept 1-week, while 4-weeks 20 FC. Even if partially inhibited by drought, showed an extremely higher total biomass, well water use efficiency (WUE) spelt. Photosynthetic parameters were reduced spelt, whereas those less affected The reduction osmotic potential adjustment combination increases antioxidant metabolism indicate prevalence tolerance mechanisms. lack effect on along reductions stomatal conductance Buckwheat mechanisms, its physiological almost not extreme drought. Overall, strong damages under mild managed cope reducing requirements increasing WUE order photosynthetic activity. appears be conditions, not.

Polyphosphate fertilizer impacts the enzymatic and non-enzymatic antioxidant capacity of wheat plants grown under salinity

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: July 11, 2023

Abstract By 2050, the predicted global population is set to reach 9.6 billion highlighting urgent need increase crop productivity meet growing demand for food. This becoming increasingly challenging when soils are saline and/or deficient in phosphorus (P). The synergic effect of P deficiency and salinity causes a series secondary stresses including oxidative stress. Reactive Oxygen Species (ROS) production damage plants caused either by limitation or salt stress may restrict overall plant performances leading decline yield. However, application adequate forms doses could positively impact growth enhances their tolerance salinity. In our investigation, we evaluated different fertilizers (Ortho-A, Ortho-B Poly-B) increasing rates (0, 30 45 ppm) on plant's antioxidant system uptake durum wheat (Karim cultivar) grown under (EC = 3.003 dS/m). Our results demonstrated that variations capacity plants, at both, enzymatic non-enzymatic levels. Remarkably, strong correlation was observed between uptake, biomass, various parameters sources. Soluble considerably enhanced total compared with control (C+). Indeed, salt-stressed fertilized exhibited robust revealed activities Catalase (CAT) Ascorbate peroxidase (APX) significant accumulation Proline, polyphenols content (TPC) soluble sugars (SS) as well increased Chlorophyll (CCI), leaf protein unfertilized plants. Compared OrthoP ppm P, Poly-B fertilizer showed positive responses where reached + 18.2% content, 156.8% shoot 93% CCI, 84% 51% CAT activity, 79% APX TPC 40% SS C+. implies PolyP might be an alternative suitable management fertilization
