Peppermint (Mentha piperita L.), a member of Lamiaceae family, is an important medicinal plant that has many useful properties. Copper is an essential micronutrient for normal plant growth and metabolism.The aim of this study was to examine the effects of copper sulphate and copper nanoparticles on morpho-physiological traits and essential oil composition of peppermint. Seven treatments of copper sulphate and copper nanoparticles in three concentrations (0.5, 1.0 and 1.5 g/l) and control were applied in foliar application three times of the interval of 15 days up to flowering stages of peppermint in Karaj, Iran in 2015. Copper nanoparticles (1.0 g/l) increased chlorophyll content and essential oil percentage of 35% and 20% higher than control, respectively. The copper sulfate (0.5 g/l) increased dry matter yield up to 58% higher than control. The effects of treatments were significant on 17 out of 34 compositions. Copper nanoparticles (1.0 g/l) increased menthol, menthone and menthofuran content up to 15, 25 and 65% higher than in control, respectively. Foliar application of copper sulfate (0.5 g/l) and copper nanoparticles (1.0 g/l) in flowering stage were suggested for increase of dry matter production, essential oil content and composition, respectively.

Mięta pieprzowa (Mentha piperita L.) z rodziny Lamiaceae jest ważną rośliną leczniczą o wielu zastosowaniach. Miedź jest ważnym mikroelementem niezbędnym do prawidłowego wzrostu i metabolizmu roślin. Celem pracy było zbadanie wpływu siarczanu miedzi i nanocząstek miedzi na cechy morfologiczne i fizjologiczne oraz na skład olejku eterycznego mięty pieprzowej. Siarczan miedzi i nanocząstki miedzi podawano dolistnie trzykrotnie w odstępie 15 dni aż do fazy kwitnienia. Hodowano także grupę kontrolną w trzech stężeniach (0,5, 1,0 i 1,5 g/l). Badanie przeprowadzono w Karaj w Iranie. Nanocząstki miedzi (1,0 g/l) spowodowały wzrost zawartości chlorofilu i olejku eterycznego (w %), odpowiednio o 35 i 20% w stosunku do grupy kontrolnej. Siarczan miedzi (0,5 g/l) zwiększał suchą masę surowca o 58% w porównaniu z grupą kontrolną. Wpływ nawożenia był istotny statystycznie w przypadku 17 związków spośród 34 składników olejku. Nanocząstki miedzi (1,0 g/l) zwiększyły zawartość mentolu, mentonu i mentofuranu odpowiednio do 15, 25 i 65% w porównaniu z grupą kontrolną. Podanie dolistne siarczanu miedzi (0,5 g/l) i nanocząstek miedzi (1,0 g/l) w stadium kwitnienia może powodować zwiększenie produkcji suchej masy surowca oraz wpływać na zawartość i skład olejku eterycznego.

Silicon plays an important role in providing tolerance to various abiotic stresses and augmenting plant resistance against diseases. However, there is a paucity of reports about the effect of silicon on bacterial and viral pathogens of plants. In general, the effect of silicon on plant resistance against bacterial diseases is considered to be due to either physical defense or increased biochemical defense. In this study, the interaction between silicon foliar or soil-treatments and reduced bacterial and viral severity was reviewed. The current review explains the agricultural importance of silicon in plants, refers to the control of bacterial pathogens in different crop plants by silicon application, and underlines the different mechanisms of silicon-enhanced resistance. A section about the effect of silicon in decreasing viral disease intensity was highlighted. By combining the data presented in this study, a better comprehension of the complex interaction between silicon foliar- or soil-applications and bacterial and viral plant diseases could be achieved.

To investigate the changes in selected morphological traits and yield of coriander (Coriandrum sati- vum L.) in response to fertilization and salicylic acid foliar spraying under different irrigation intervals, two field experiments were conducted as split-factorial based on randomized complete block design with three replicates in 2014 and 2015. Treatments were three irrigation intervals (irrigation after 60, 90 and 120 mm evaporation from class A pan) and combination of fertilization (control, urea 100 kg ha–1, Nitrokara (bio-fertilizer), and 50% urea + Nitrokara) and salicylic acid (0 and 1 mM) that were allocated to the main and sub-plots, respectively. The results showed that plant height, length of the longest internode, stem diameter, branches per plant, dry weights of roots and leaves and fruit yield of coriander were reduced and root length enhanced with increasing the irrigation intervals. However, all of the nitrogen fertilizers, especially combined application of 50% urea and Nitrokara, and salicylic acid spraying, improved the selected morphological traits, and consequently fruit yield per unit area under favorable and limited irrigations.

A way to alleviate excessive Mn nutrition of plants is through silicon application. The aim of the present study was to examine the effect of different Si concentrations in a nutrient solution and Si plant spraying treatments (in the form of silica sol) on the yielding and nutritional status of hydroponically grown lettuce under Mn-stress. The experiments were conducted under controlled conditions in a phytotron. The influence of the following Si levels in the nutrient solution (5.5 – control; 15.5; 23.25 and 31 mg Si dm-3) and foliar sprays (distilled water; Si solution) were investigated. Silicon supplied through fertigation significantly affected the plant’s nutrient status and alleviated the Mn stress, increasing fresh matter production, RWC (Relative Water Content) and the number of leaves per plants, while decreasing the share of dry matter. The Si nutrition did not change the content of Mn in the leaves, but caused a significant increase in N, P, Na, Fe and Si concentrations with a simultaneous decrease of Zn and Cu levels. The content of Ca, Mg and K was relatively stable (except for the treatment with the most intensive Si nutrition). Generally, the concentrations of N, P, K, Ca, Mg, Na and Fe within the tested Si range were higher than in the control, while being lower in the case of Zn and Cu. Overall, the foliar application of Si did not change plant yielding, the number of leaves on plants and most macro- and microelement concentration in leaves, but modified significantly the RWC as well as the Cu and Na content. The dry matter content under Si nutrition was varied. In summary, an effective method to alleviate Mn-stress is to apply silica sol to a nutrient solution used for plant fertigation.

A field experiments were conducted during the two summer seasons of 2015 and 2016 in saline soil (ECe = 9.0 dSm⁻¹), at Fayoum province, Egypt to study the effect of ascorbic (AsA), as foliar application alone or combined with cyanobacteria (CB) on growth, yield, its components and nutritional status of sunflower plants variety Sakha 54. Treatments comprised 2 ascorbic acid (AsA) levels with or without seed inoculation with cyanobacteria (CB). They were 1 mM AsA, 2 mM AsA, 1 mM AsA + CB and 2 mM AsA + CB in addition to the control treatment in which seeds were not received CB and their plants were sprayed with distilled water. Results could be summarized as follows: increasing the addition of ascorbic acid concentration up to 1Mm with combination of CB increased significantly values of growth attributes (e.i., plant height, of leaves no./plant, shoot dry weight and leaf area), photosynthetic pigments (chlorophyll a, b and carotenoids), physiological responses (total soluble sugars, proline and soluble phenols) as well as the head diameter, seed yield/ plant, 100 seed weight and seed yield (t ha⁻¹). Also, N, P, K, Fe, Mn, Zn and oil percentage of sunflower seeds with compared to control treatment in both years. Generally, the results in most cases, demonstrate that the all parameters increased significantly by using the concentration of ascorbic acid 1Mm combined with CB in both seasons.
