Abstract

This study was carried out for the estimation of polyphenols (TP) and induction of oxidative enzymes polyphenol oxidase (PPO) and peroxidase (POD) in sunflower plants through seed immersion in agrochemicals of salicylic acid (SA) and water soluble chitosan (CH) in addition to a conidial suspension of Trichoderma harzianum and then analysis of plant content of carbohydrates and protein. The highest level of PPO 253.3 U ꞏ min –1 was detected in 50 ppm SA for 6 h. Next was T. harzianum when catalyzed PPO with 193.67 U ꞏ min –1. Peroxidase was substantially catalyzed in accordance with the increment of inducers. Sunflower roots induced TP with up to 4.88 mg ꞏ g –1 in plants treated with SA at 50 ppm for 6 h and then declined with an increasing SA dose. The total carbohydrate content in leaves of 320 mg ꞏ 100 g –1 was found in treatments of CH at 50 ppm for 6 h. In roots, a carbohydrate content of 500 mg ꞏ 100 g –1 was observed using CH 75 ppm for 6 h. Trichoderma harzianum remarkably increased proteins in leaves and roots by up to 25% compared to 16.9% in the control. These results suggest that inducing the plants’ own defense mechanism by applying salicylic acid and chitosan and bio-control of T. harzianum may offer alternative methods for controlling charcoal rot of sunflower due to the creation of defensive enzymes and could support plant vigor by enhancement of its protein and carbohydrate content.

Abstract

The efficiency of a formulated salicylic acid (Zacha 11, 500 mg · l–1) and a Bacillus bioproduct (JN2-007, 1 × 107 cfu · ml–1) in controlling cassava root rot disease and enhancing growth was evaluated. The results revealed that cassava stalk soaking and foliage spraying with Zacha 11 formulation or Bacillus subtilis bioproduct could increase cassava growth at 60 days after planting under greenhouse conditions. Zacha 11 gave the tallest stem height (11.67 cm), the longest root length (18.91 cm) and the greatest number of roots (49.50). Fusarium root rot severity indices of all treated treatments were reduced, and were significantly lower than that of the water control. Plants treated with Zacha 11 and JN2-007 had disease severity reduction of 53.33 and 48.33%, respectively. Furthermore, all treatments increased the endogenous salicylic acid (SA) content in cassava plants at 24 inoculation with significant differences when compared to the untreated samples. The efficacy of Zacha 11 and JN2-007 was evaluated at two field locations, using two different cassava varieties, cv. Rayong 72 and CMR-89. The results showed that all elicitors could suppress root rot disease as well as bacterial leaf blight. Furthermore, the elicitors helped cassava plants cv. Rayong 72 and CMR-89 to increase tuber weight, yield and starch contents, compared to the water control. Thus, it is possible that these formulations could be effective in controlling diseases and increasing cassava productivity.

Abstract

Since plant responses to selenium nanoparticles (nSe) had not been clarified, this study was carried out to evaluate the effects of nSe (10 and 100 μM) on photosynthesis performance, ion homeostasis, antioxidant system, and phenylpropanoids in strawberry exposed to salt stress. Inductively Coupled Plasma-Mass Spectroscopy analyses indicated that foliar-applied nSe can be taken up by leaves and trans-located to roots. Salinity led to an increase in Na concentration and reductions in Ca and K contents which were relieved by the nSe applications. Moreover, the nSe treatment at 10 μM alleviated the NaCl-induced lesion to PSII functioning, contributing to improvement in water-splitting complex (Fv/Fo) under salinity. The exposure to nSe at a concentration of 100 µM exhibited a moderate stress, determined by the increases in hydrogen peroxide (H2O2) and lipid peroxidation rate (membrane integrity index). The nSe10 treatment increased catalase activity and phenylpropanoid derivatives contents (salicylic acid, catechin, and caffeic acid) and decreased the content of oxidants under salinity condition. Consequently, nSe utilization at a suitable dose can be an effective method to alleviate signs of salt stress via improvements in photosynthesis, ion hemostasis, photosynthesis performance, salicylic acid (a vital signaling defensive hormone), and antioxidant machinery.

Abstract

In the years 2018‒2020, the effectiveness of three synthetic active substances (acequinocyl, fenpyroximate, spirodiclofen), one substance derived from Streptomyces spp. (abamectin), a plant extract (orange oil) and silicone polymers in controlling Phyllocoptes gracilis in two Polish raspberry plantations (v. ‘Glen Ample’) was assessed. All the substances showed high and comparable efficacy against the tested pest, significantly reducing its population. However, their effects occurred at different times after the application. The strongest immediate control was shown by silicone polymers, followed by abamectin and spirodiclofen. The full effect of fenpyroximate application was visible after approx. 2 weeks, while acequinocyl was effective 3‒4 weeks after the application. Moreover, the content of phenolic compounds, sterols and triterpenoids was determined in leaves of plants treated with spirodiclofen, orange oil and silicone polymers. The observed increase in the content of salicylic acid and changes in the content of triterpenoids in leaves may indicate a stimulating effect of the substances to the natural defense processes of plants.

Abstract

In this paper, we present results indicating ozone effect on visible plants response as well as on other parameters, such as dry weight, chlorophyll concentration, cell membrane stability and salicylic acid content in bioindicator plants. Ozone-resistant and -sensitive clones of white clover (Trifolium repens L. cv. "Regal") were used in the investigations. The experiment was carried out in ambient air conditions of the Wielkopolska province (Poland) in 2005 growing season. The exposure led to changes in the level of plant response parameters that might be used as potential biomarkers of oxidative stress triggered by tropospheric ozone in ambient air conditions.

Abstract

Orobanche crenata parasitism on lentil ( Lens culinaris Medik) is one of the most destructive factors for this crop in Morocco. Field and pot assays were performed to study the mitigation of O. crenata stress on two lentil genotypes, Bakria (partially resistant to O. crenata) and Zaaria (susceptible), using salicylic acid (SA) and indole acetic acid (IAA). These two hormones were applied separately at concentrations of 1 mM and 0.09 mM, respectively, using seed pre-treatment and/or foliar spray methods. SA and IAA seed pre-treatment for the susceptible genotype Zaaria and foliar spray for the resistant genotype Bakria gave the best control of O. crenata under field and controlled conditions. This control reached ~91% in Zaaria and 83% in Bakria and was sometimes accompanied by an increase in plant growth and seed yield compared to the untreated plants. Biochemical assays showed that SA and IAA reduced O. crenata infestation in lentil through induction of systemic acquired resistance characterized by increasing activities of phenol metabolizing enzymes (phenylalanine ammonia-lyase, peroxidase, and polyphenol oxidase) implicated in natural defense systems of plants. Treatment of plants with SA or IAA could be an alternative strategy of crop protection with more satisfactory preservation of the environment.

Abstract

Since silver nanoparticles (AgNPs) are used as nanofungicides and nanopesticides in agriculture, the toxicity of AgNPs as well as AgNO3 must be determined. Besides this, we evaluated the combined effects of salicylic acid (SA) and nitric oxide (NO) on responses of Phlomis tuberosa plants to Ag-induced stress. The results of growth parameters together with measurement of malondialdehyde (MDA) indicated that exposure to 1000 mg L–1 of AgNPs or AgNO3 exerted more toxicity, which was closely associated with the over– accumulation of ROS and the reduction of photochemical functioning. However, SNP (NO) and SA addition successfully alleviated adverse impact of AgNPs on Phlomis seedlings. Maximum amelioration of Ag-induced stress was found by combined treatments of SA+NO. Phlomis plants primed with SA+NO exhibited higher synthesis of chlorophyll b and carotenoid pigments to ameliorate AgNP-induced adverse effects on chlorophyll fluorescence parameters. SA+NO led to high levels of proline under both AgNPs and AgNO3 treatments. A further increase in antioxidants (phenolic compounds) was observed in NO-primed plants under AgNPs- induced stress, which was attendant with the high level of CAT and APX activities. Increase in total Ag translocation into shoot organs and cell survival were also enhanced by SA+NO under AgNPs stress. We concluded that SA+NO mitigated the inhibitory effects of AgNPs stress on the photosynthetic apparatus by increasing the phenolic compounds and carotenoids as well as by regulating accumulation of Ag, ROS and antioxidants. The present findings provide important knowledge to design strategies that minimize the negative impact of AgNPs and AgNO3 on crops.
