Abstract The effect of plant propagation method on growth parameters and the yield of above-ground biomass in two species of gigantic grasses were measured during three growing seasons. Plants were multiplied in explant culture and through traditional methods – by rhizome segments (Miscanthus × giganteus) or by stem cuttings (Arundo donax). In the case of M. × giganteus, in vitro-multiplied plants produced more shoots with significantly lower diameter, but the differences in the number of shoots, plant height and the yield of dry biomass were not statistically significant. Different results were observed for A. donax, where in vitro-multiplied plants showed significantly weaker results in all parameters, with the exception of the number of shoots in the first measured season. In both the species, there was observed the strong effect of the year. While in M. × giganteus the yield of dry biomass gradually decreased during the measured years, it increased in the case of giant reed.

Sewage sludge (SS) is a waste originated from wastewater treatment that could be considered an interesting source of organic matter and nutrients for agricultural production. Our experiments aimed to assess the effect of SS on the growth parameters and the biomass yield of giant reed (Arundo donax L.) plants. Experiments were carried out in pots during two growing seasons, where samples of dried SS were applied in doses of 5 or 15 t ha−1. The number of shoots per plant was significantly higher with the application of 5 t ha−1 of SS into arable soil compared to the control treatment and did not increase with the dose of SS. On the other hand, the height of the plants was gradually elevated with the dose of SS. The diameter of the shoots was positively affected by the dose of 15 t ha−1, and it was the only parameter with significant differences between the used types of SS. The biomass yield increased by 1.2–2.7× depending on the type and dose of SS. Cu and Zn uptake, as micronutrients present in SS, and their accumulation in the aboveground parts were significantly higher for plants cultivated in the presence of SS.

Giant reed (Arundo donax L.) is a perennial, herbaceous grass, it has been spread all over the world from continent to tropical conditions by human activities. In continental climate, especially Hungary, it has been considered as ornamental species, due to its decorative appearance, striped variants’ colour of leaves, long growing season and low maintenance requirements. It does not produced viable seeds, so it can be propagated vegetative ways by rhizomes or stem cuttings and by in vitro biotechnology methods. Because of its growth habits and good adaptation capability, it has been considered invasive weed primarily in coastal regions in warmer climate areas. In the previous century, giant reed produced for paper/cellulose/viscose production, woodwind musical instruments, stakes for plants or fishing rods etc. Over the last few decades, it has been produced for bioenergy purposes (bioethanol, biogas, direct combustion) or utilize as chemical basic compounds or construction materials. It has been considered a dedicated promising biomass crops thanks to high biomass production, high energy balance of cultivation and adaptability of different kind of soils and conditions. The objective of the present paper is to overview the most significance literature data on giant reed production and utilization, compare to own experimental data and economic calculations and to determine some critical factors, advantages and disadvantages of giant reed production compare to other biomass species.

The increasing interest in<em> Arundo donax,</em> a perennial lignocellulosic species only reproducing by propagation, requires the setup of cheap, simple and reliable techniques. Considering these targets, stem cutting offers considerable advantages. The present investigation aimed to compare: i) plants obtained by different propagation methods (by rhizome and micropropagation mother plants); ii) plants obtained by stem cuttings from basal, central and apical parts of the stem; iii) different planting periods (spring, summer, autumn). The obtained results showed that the number of new shoots from stem buds was: i) higher in the spring and lower in the summer planting period; ii) higher from cuttings obtained by micropropagated than rhizome mother plants, both in spring and summer plantings; iii) decreasing passing from the basal to the apical stem portion; iv) partly unexpressed in the autumn planting period; v) lower from one-year stem cuttings as compared to two-year stem cuttings.

AbstractGiant reed (Arundo donaxL.) has recently shown great potential as a feedstock for the bioenergy industry. However, beforeA. donaxcan be grown commercially, due to its invasive nature, management strategies must be developed to reduce the risk of unintended spread. This research was conducted in northeastern Oregon (USA) during two growing seasons. Nine control strategies were evaluated in a field that previously hadA. donaxas a crop. The control strategies included mechanical practices (stem cutting and rhizome digging), physical practices (covering with an opaque tarp), chemical practices (glyphosate applications at different rates and timings), and a combination of these practices. Spring samplings ofA. donaxregrowth in the season following treatments indicated that stem cutting in the spring without follow-up control practices provided no control. Covering plants with a tarp after cutting them (either with or without a glyphosate treatment after cutting) resulted in 96% control. Application of glyphosate alone also resulted in excellent control, although timing of application was an important factor for maximizing efficacy. The best results were found when the maximum dose (10.2 L ai ha−1) was split among two or three applications (>99% of control) compared with the maximum dose applied once (75% to 94%). Control was lower (73% to 89%) for two of the strategies that included mechanical practices, stem cutting + glyphosate and rhizome digging, in comparison to other strategies involving tarps and/or glyphosate applications (88% to 100%). Results indicated that it is very difficult to eradicate volunteerA. donaxin 1 yr, but very good control can be achieved with several of the strategies tested.

AbstractGiant reed recently was promoted as a biofuel crop in Oregon. Because giant reed is a highly invasive plant in North American rivers, the planting of this species in Oregon is a cause for concern to scientists and local land managers. However, some growers in the area were interested in producing giant reed as a rotational crop. To find potential herbicides to control the giant reed or to control it as a volunteer, 13 foliar and 13 cut-and-spray herbicide treatments were preevaluated in greenhouse studies. We chose 10% and 85% reduction in aboveground biomass for either crop safety or control, respectively. When applied at the standard rates, acetochlor and dimethenamid-p reduced aboveground dry biomass of the crop by 10% or less. Acetochlor+atrazine, atrazine, flufenacet, and mesotrione reduced aboveground biomass of the crop by at least 85%, indicating that these compounds have the potential to serve as controls against giant reed.

Background: In recent years, great progress has been made in reducing the high level of malaria suffering worldwide. There is a great need to evaluate drug resistance reversers and consider new medicines against malaria. There are many approaches to the development of antimalarial drugs. Specific concerns must be taken in to account in these approaches, in particular there requirement for very in expensive and simple use of new therapies and the need to limit drug discovery expenses. Important ongoing efforts are the optimisation of treatment with available medications, including the use of combination therapy. The production of analogs of known agents and the identification of natural products, the use of compounds originally developed against other diseases, the assessment of overcoming drug resistance and the consideration of new therapeutic targets. Liver and spleen are the important organs which are directly associated with malarial complications. Aim: An analysis the Activity of Adenosine Triphosphatase, Aryl Hyrocarbon Hydroxylase Enzymes and Malondialdehyde in spleen Explant Culture. Objective: To determine in-Vitro Effect of Chlorquine and Picroliv on Plasmodium Berghei Induced Alterations in the Activity of Adenosine Triphosphatase, Aryl Hyrocarbon Hydroxylase Enzymes and Malondialdehyde in spleen Explant Culture. Material and method: 1-Histological preparation of spleen explants for paraplast embedding 2-Biochemicalstudies (Enzymes (Atpase, ALP&GST) and the level of protein, Malondialdehyde (MDA). Result: Splenomegalyis one of the three main diagnostic parameters of malaria infection besides fever and anaemia. Many enzymes present in the liver and spleen may also be altered or liberated under different pathological conditions. Enzymes (ATPase, ALP&GST) and the level of protein, Malondialdehyde (MDA) content was found to increase in the liver and spleen explants during malarial infection. In the liver and spleen derived from parasitized CQ treated animals, the activity of all the above enzymes (ATPase, ALP&GST) and the level of protein & MDA of liver/spleen reversed towards the normal for all the 4or3 days of incubations. Picroliv efficacy decreased with the increment of parasitaemia and at 60%parasitaemia. Conclusion: Alkalinephosphatase (ALP) was found to increase with increasing parasitaemia. After the addition of Picroliv to the medium, a decrement in the activity was observed up to day 4 of culture.A similar positive effect of Picroliv was observed on the ATPase and ALP activity of spleen explants.DNA and protein contents also increased in the parasitized liver cultured in the presence of picroliv.On the contrary, in the spleen explants DNA, protein and MDA content were found to decrease after Picroliv supplementation to the culture medium.

Structural and physiological responses of chrysanthemum to repeated osmotic stress were studied. Plants were cultured for 2 weeks (for each stress1 and stress 2) on half MS supplemented with mannitol 100 mM (Treatment I) and 200 mM (Treatment II). First stress inhibited growth parameters stronger than second stress in treatment I. In treatment II both stress events strongly inhibited growth parameters of micro‐shoots. Proline content exceeded control 6 ‐ 8 times after 1st stress, and 2 ‐ 5 times after the 2nd stress in treatments I and II, respectively. Soluble protein was accumulated in leaves during both stress exposures, and 2 ‐ 2.5 times exceeded control after the 2nd stress. Relative water content in both treatments increased after the 2nd stress exposure. In treatment II chlorophyll а and carotenoids contents were 8.78 and 4.62 mg/g comparing to control (4.21 and 2.25 mg/g, respectively) after the 1st stress. But after the 2nd stress there was no difference with control.Plant Tissue Cult. & Biotech. 27(2): 161-169, 2017 (December)

Riparian Systems

Arundo donax (giant reed) is invasive in Mediterranean, sub-, and tropical riparian systems worldwide. The armored scale Rhizaspidiotus donacis is approved for biocontrol in North America, but an adventive population was recently discovered in southern California. We documented this population’s distribution, phylogeny, phenology, potential host spillover to Phragmites spp., and potential for parasitism by a common biocontrol parasitoid of citrus scale. The adventive scale was found within a single watershed and is genetically closest to Iberian scale genotypes. Rhizaspidiotus donacis developed on Phragmites haplotypes but at much lower densities than Arundo. The adventive population is univoltine, producing crawlers from March-June. Aphytis melinus parasitoids exhibited sustained interest in R. donacis during choice and no-choice trials and oviposition resulted in a small second generation. Rhizaspidiotus donacis appears limited in distribution by its univoltinism and sessile adult females. This presents challenges for broad biocontrol implementation but allows for targeted application. The genetic differentiation between imported biocontrol samples and adventive populations presents an opportunity for exploring benefits of hybrids and/or alternative genotypes where establishment has been difficult. While unlikely to occur in situ, spillover to vulnerable endemic Phragmites or deleterious parasitoid effects on scale biocontrol agents warrants consideration when planning use of R. donacis.
