The olive tree ( Olea europaea L.) is commonly grown in the Mediterranean basin and able to resist severe prolonged drought. Levels of proline (PRO) malondialdehyde (MDA), lipoxygenase (LOX) activity were determined 2‐year‐old plants (cv. ‘Coratina’) environmental conditions characterized by high temperatures photosynthetic photon flux density levels gradually subjected a controlled water deficit for 20 days. Before during experimental period, leaf root samples collected analysed PRO MDA....
Abstract. Olive trees (Olea europaea L.) are commonly grown in the Mediterranean basin where prolonged droughts may occur during vegetative period. This species has developed a series of physiological mechanisms, that can be observed several plants macchia, to tolerate drought stress and grow under adverse climatic conditions. These mechanisms have been investigated through an experimental campaign carried out over both irrigated drought-stressed order comprehend plant response stressed...
Soils and crops in orchard agrosystems are particularly vulnerable to climate change environmental stresses. In many soils, soil biodiversity the ecosystem services it provides under threat from a range of natural manmade drivers. this scenario, sustainable use aimed at increasing organic matter (SOM) SOM-related benefits, terms quality fertility, plays crucial role. The role macrofaunal organisms as colonizers, comminutors engineers within together with their interactions microorganisms,...
Photosynthesis is a pivotal process that determines the synthesis of carbohydrates required for sustaining growth under normal or stress situation. Stress exposure reduces photosynthetic potential owing to excess reactive oxygen species disturb proper functioning apparatus. This decreased photosynthesis associated with disturbances in carbohydrate metabolism resulting reduced stress. We evaluated importance melatonin reducing heat stress-induced severity wheat (Triticum aestivum L.) plants....
Understanding the induction of plant defenses against viruses using biocontrol agents is essential for developing new strategies these pathogens, given ineffectiveness chemical treatments. The ability Trichoderma harzianum, strain T-22 (T22) to control Cucumber mosaic virus (CMV) in Solanum lycopersicum var. cerasiforme plants and changes physiology tomato treated/infected with T22/CMV were examined. Plant growth-promoting effects, photosynthetic performance, reactive oxygen species (ROS)...
People are facing uncertain and difficult times in the face of Covid-19 pandemic. The benefits plants (psychological, health, economic, productive) this period forced isolation can be key importance. If many us have to self-isolate urban or suburban environments, we need something do keep our bodies minds active fed. In such a challenging scenario, vegetable garden home spaces bring recreational, economic environmental benefits. Regardless pandemic, there is untapped potential for kind...
This study explored the interactive effect of ethephon (2-chloroethyl phosphonic acid; an ethylene source) and sulfur (S) in regulating antioxidant system ABA content maintaining stomatal responses, chloroplast structure, photosynthetic performance mustard plants (Brassica juncea L. Czern.) grown under 100 mM NaCl stress. The treatment (200 µL L−1) S mg kg−1 soil) together markedly improved activity enzymatic non-enzymatic components ascorbate-glutathione (AsA-GSH) cycle, resulting declined...
Nitric oxide (NO) and abscisic acid (ABA) play a significant role to combat abiotic stress. Application of 100 µM sodium nitroprusside (SNP, NO donor) or ABA alleviated heat stress effects on photosynthesis growth wheat (Triticum aestivum L.) plants exposed 40 °C for 6 h every day 15 days. We have shown that synergistically interact reduce the via reducing content H2O2 thiobarbituric reactive substances (TBARS), as well maximizing osmolytes production activity expression antioxidant enzymes....
Abstract The breakdown of plant material fuels soil functioning and biodiversity. Currently, process understanding global decomposition patterns the drivers such are hampered by lack coherent large‐scale datasets. We buried 36,000 individual litterbags (tea bags) worldwide found an overall negative correlation between initial mass‐loss rates stabilization factors plant‐derived carbon, using Tea Bag Index (TBI). factor quantifies degree to which easy‐to‐degrade components accumulate during...
The effects of drought on the activities superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), guaiacol (POD), indoleacetate oxidase (IAAox) and polyphenol (PPO) were studied in 2-year old Olea europaea L. (cv. 'Coratina') plants grown under high temperatures irradiance levels gradually subjected to a controlled water deficit. After 20 d without irrigation, mean predawn leaf potential fell from -0.37 -5.37 MPa, decreases net photosynthesis transpiration occurred. SOD, APX,...
We evaluated the osmotic adjustment capacity of leaves and roots young olive (Olea europaea L.) trees during a period water deficit subsequent rewatering. The trials were carried out in Basilicata (40°24' N, 16°48' E) on 2-year-old self-rooted plants (cv. 'Coratina'). Plants subjected to one four drought treatments. After 13 days drought, reached mean predawn leaf potentials –0.45 ± 0.015 MPa (control), –1.65 0.021 (low stress), –3.25 0.035 (medium stress) –5.35 0.027 (high stress). Total...
The effect of four triazinyl-sulfonylurea herbicides (cinosulfuron, prosulfuron, thifensulfuron methyl, triasulfuron) on soil microbial biomass, respiration, metabolic activity, quotient, and some enzymatic activities (acid alkaline phosphatase, β-glucosidase, arylsulphatase, fluorescein diacetate hydrolysis) were monitored under controlled conditions over 30 days. applied at the normal field dose (FD) ten-fold (10 FD) dose, in order to mimic a long term toxic effect. measured parameters...
Arabidopsis thaliana L. is a model plant but little information available about morphological root changes as part of phytohormonal common response against both biotic and abiotic stressors. For this purpose, two-week-old seedlings were treated with 10 µM CdSO4 or infected CMV. After 12 days the entire aerial parts system analyzed, presence CMV accumulation Cd detected. Microscopic analysis revealed that influenced morphology by marked development in length hairs an intense branching if...
The research was focussed on the effects of cadmium (Cd) and arsenic (As), alone or combined, Arabidopsis post-embryonic roots, with attention to quiescent centre formation development in relation auxin homeostasis. To aim, morphological histochemical analyses were carried out seedlings, exposed not Cd and/or As, wild type, transgenic lines useful for monitoring identity, localization cellular influx efflux. Moreover, levels expression YUC6 biosynthetic gene monitored As type seedlings....
To date, almost no information is available in roots and shoots of the model plant Arabidopsis thaliana about hierarchic relationship between metal accumulation, phytohormone levels, glutathione/phytochelatin content, how this relation affects root development. For purpose, specific concentrations cadmium, copper zinc, alone or triple combination, were supplied for 12 days to vitro growing seedlings. The accumulation these metals was measured shoots, a significant competition uptake...
Summary Seventy‐eight samples of southern Italy honey from five different floral origins (chestnut, eucalyptus, citrus, multifloral and sulla) were screened to quantify the polyphenol metal contents, evaluate antioxidant activity determine correlations between parameters analysed. The average content was 12.06 mg gallic acid equivalent per 100 g 7.92 quercetin honey, for total phenolic flavonoid respectively. ranged 58.40% (eucalyptus honey) 60.42% (chestnut in ABTS assay, 152.65 μ m Fe (II)...
