Abstract

Chlorophyll Fluorescence as a Criterion for the Diagnosis of Abiotic Environmental Stress of <i>Miscanthus x Giganteus</i> Hybrid

Highlights

One of the present environmental problems is soil degradation and contamination [1].Kertesz [2] report that degraded land occupies an area of 323 million hectares (3.7% of total land used), with a chemically degraded area of 240 million hectares and a physically degraded area of 83 million hectares
No significant differences within the treatments were found, and we can conclude that the evaluated abiotic stressors did not affect the variability of this trait
To different doses of abiotic stressors, significant differences were not recorded for dates of measurement

Summary

Introduction

One of the present environmental problems is soil degradation and contamination [1].Kertesz [2] report that degraded land occupies an area of 323 million hectares (3.7% of total land used), with a chemically degraded area of 240 million hectares (loss of nutrients 136, salinization 77, pollution 21 and acidification 6 million hectares) and a physically degraded area of 83 million hectares. One of the present environmental problems is soil degradation and contamination [1]. The mitigation of potential health hazards and land scarcity due to land-use change can be addressed by restoring the function and ecosystem services of contaminated land. Physico-chemical remediation options are criticized as being costly and not providing environment-friendly solutions. Nature-based solutions based on the use of plants and associated microorganisms could be a sustainable, cost-effective option to reduce pollutant exposure. Phytomanagement aims at using valuable non-food crops to alleviate environmental and health risks induced by pollutants, and at restoring ecosystem services. Suitable plant species must be tolerant to contaminants, reduce their transfer into the food chain, and efficiently produce marketable biomass [3]
