Streszczenie:

Atriplex patula L., spreading atriplex, A. prostrata Boucher ex DC., halberd-leaved atriplex, and A. rosea L., red scale, are introduced annual weeds occurring in gardens, fields and orchards in various parts of Canada. Red scale is expanding its range in western Canada where plants are abundant enough in some areas to cause hay fever from large amounts of pollen shed in late summer. Spreading atriplex occurs wide-ranging across Canada, it is rare in western Canada and occurs commonly from southern Ontario to Cape Breton Island; halbred-leafed atriplex has a similar distribution pattern but it occurs commonly throughout its range. Both can be weedy in small grains and gardens.Key words: Atriplex, orache, weed biology

Streszczenie:

AbstractAn in vivo digestibility trial was conducted by feeding sheep the leaves, fruits and twigs of Atriplex barclayana in a proportion roughly equivalent to that eaten by sheep grazing freely in Atriplex plantations. Four treatments were imposed on each of four sheep in a 4 × 4 Latin-square experimental design: Atriplex offered alone or with 100, 200 or 300 g/day tapioca meal.The mean apparent digestibility of the Atriplex dry matter (DM) and organic matter (OM) consumed were 0·59 and 0·56, respectively. Addition of tapioca to the Atriplex in the diet did not improve these digestibility coefficients. The low OM content of 760 g/kg together with its digestibility of 0·56 resulted in the Atriplex having a low metabolizable energy concentration of 6·28 MJ per kg DM. The in vitro apparent DM digestibility of Atriplex was approximately 0·09 higher than the in vivo apparent digestibility.The mean nitrogen concentration of the Atriplex DM was 16·6 g/kg, and its apparent digestibility 0·73, which was not improved by the addition of tapioca to the diet. Nitrogen retention of the sheep eating only Atriplex was proportionately 0·17 of the nitrogen intake. The addition of 300 g tapioca improved nitrogen retention to 0·27 but was not significantly different from the other treatments.Water intake and urine excreted were as high as 14 and 12 I/day respectively, for an Atriplex DM intake of about 1300 g/day. During the experiment the sheep only maintained live weight, despite daily intakes of up to 1200 g Atriplex DM and up to 300 g tapioca.

Streszczenie:

Based on critical observations on both herbarium specimens (including type material) and living plants in the wild, we demonstrate that Thalictrum spiristylum, described from northwestern Yunnan, China, is conspecific with T. atriplex, a Chinese species widely distributed in southwestern Qinghai, western Sichuan, northwestern Yunnan, and southeastern Xizang. We therefore reduce T. spiristylum to the synonymy of T. atriplex. Morphological distinction between T. atriplex and T. uncatum is clarified. Lectotypification is also proposed for T. atriplex.

Streszczenie:

A field observation trial was carried out at Agricultural Research Center, Rumais, Sultanate of Oman to evaluate the productivity and forage quality of two species of Saltbush viz. Quali saltbush (Artiplex lentiformis L.) And Fourwing saltbush (Atriplex canescens L), both are perennial and of North American origin. Plants were irrigated with brackish water (EC more than 10.00 dS/m) under drip irrigation and grown with minimum tillage and sub-optimum management conditions. Biomass production was evaluated in terms of five characters i.e. plant height, plant width, plant volume, green fodder yield/plant and green fodder yield/ha over the experimental period (747 d). Arriplex lenformis produced a total green fodder yield of 53.29 kg/plant equivalent to 59.21 t/ha as compared to that of 31.27 kg/plant (34.75 t/ha) produced by Atriplex canescens. The cut yields and interaction effects (between the species and cuts) were also significantly different with respect to all the characters. Chemical composition of the Atriplex species indicated that A Ientiformis had higher levels of Na, K, Cl and Ca as compared to A canescens. The studies of nutrient composition of bulk samples of the Atriplex species revealed that the fresh material contained 34.30% dry matter. On dry matter basis, the Atriplex material had 9.40% crude protein (CP), 24.00% crude fiber (CF), l.5% extract ( EE), 19.60% ash and 45.50% nitrogen free extract (NFE). Despite its high ash content, Atriplex material appeared to be a nutritious and cheap source of nitrogen complementation.

In vivo digestibility trials were carried out using six young rams fed with Atriplex halimus biomass harvested in summer (A) and in early autumn (B), and with a mixture of mid-autumn Atriplex halimus and wheat straw (5[ratio ]1 ratio on fresh matter basis) (C). Atriplex halimus had a high protein content (139·0, 135·9 and 193·4 g/kg DM in A, B and C respectively), but was rich in sodium chloride, especially in summer (145·9 g/kg DM), limiting its use as feed. The summer forage had a higher organic matter (OM) digestibility coefficient than the autumn forage (0·663 v. 0·530) but lower digestible OM intake (16·8 v. 29·4 g/day per kg BW0·75). In autumn forage, the combination with straw did not influence the digestibility of organic matter, whereas it enhanced DOM intake in comparison with the Atriplex halimus on its own (35·7 v. 29·4 g/day per kg BW0·75).

Streszczenie:

In 2014 Sukhorukov & Kushunina taxonomically restored the forgotten name Chenopodium pallidum applicable to a Himalayan taxon and designated its lectotype (a specimen in P) and also an epitype (in MW). However, in 2015 they published a correction to their article and demonstrated that the lectotype of C. pallidum in fact belongs to Atriplex and is most probably conspecific with A. schugnanica. The new combination Atriplex pallida was proposed, with A. schugnanica cited in its synonymy. The species of Chenopodium accepted by Sukhorukov & Kushunina in 2014 as C. pallidum was described in 2015 as C. harae Sukhor. (as “harai”), with its holotype in MW being the same specimen as the epitype of C. pallidum. However, when introducing these nomenclatural novelties, the authors did not apply properly the provisions of the ICN, according to which the rejection of an epitype (as long as its supported type retains its status) is extremely complicated, or almost impossible without conservation. Moreover, the application of a name is ultimately established by its epitype, not by the type the epitype supports (in this case, the lectotype). Following the relevant articles of the ICN, it is concluded that (1) Chenopodium pallidum, by its epitypification (but not lectotypification), is the correct name for a Himalayan species of Chenopodium (despite the fact that its lectotype in P belongs to Atriplex), (2) C. harae and Atriplex pallida are homotypic synonyms of C. pallidum; and (3) Atriplex schugnanica (if taxonomically accepted) is the correct name for a species of Atriplex from the Pamir, Karakoram, and Himalayas. It is concluded that plant taxonomists, in order to avoid nomenclatural confusion, should be extremely careful with epitypifications and should not propose epitypes without the utmost necessity. A proposal to amend the Code aimed at better regulation of the existing procedure of epitypification is desirable.

Conventional taxonomy is limited with delineating species and controversies arise with DNA barcoding based identifications. Hence, an alternative supporting approach is very much needed to identify species and differentiate them within the species based on the genetic material. 18S rRNA genes have been particularly helpful in analyzing phylogeny at the species level. In addition, bioinformatics which represents a new, growing area of science uses computational approaches to answer biological questions. Salt tolerant costal salt marsh plant of Suaeda maritima was selected for 18s rRNA sequencing to solve the ambiguity in itsspecies level identification. Similarity search of study species shared 99% similarity with 5 species of Atriplex canescens clone s128, Atriplex torreyi var. griffithsii clone p508, Spinacia oleracea, Oenothera laciniata clone,Beta vulgaris. Phylogenetic tree infer that S.maritima is closely related to Spinacia oleracea and Oenothera laciniata. Atriplex canescens (fourwing saltbush), Atriplex torreyi and Phaulothamnus spinescens, Celosia argentea found to be closely related and are in one group. Hence, this study result clearly shows thus study species evaluated from angiosperm and provides key step in understanding the evolution of salt tolerance in angiosperm.

Halophytes are capable of coping with excessive NaCl in their tissues, although some species may differ in their degree of salt tolerance. In addition, it is not clear whether they can tolerate other confounding factors and impurities associated with non-conventional waters. The experiment was performed in a greenhouse with Crithmum maritimum and Atriplex halimus plants, growing on soil and irrigated with two different water types: reclaimed wastewater (RWW) (EC: 0.8–1.2 dS m−1) and reverse osmosis brine (ROB) (EC: 4.7–7.9 dS m−1). Both species showed different physiological and nutritional responses, when they were irrigated with ROB. Atriplex plants reduced leaf water potential and maintained leaf turgor as consequence of an osmotic adjustment process. Atriplex showed higher intrinsic water use efficiency than Crithmum, regardless of the type of water used. In Crithmum, the water status and photosynthetic efficiency were similar in both treatments. Crithmum presented a higher leaf accumulation of B and Ca ions, while Atriplex a higher amount of K, Mg, Na and Zn. Crithmum plants irrigated with ROB presented higher concentrations of 1-aminocyclopropane-1-carboxylic acid and trans-zeatin-glucoside, whereas abscisic acid concentration was lower. Atriplex showed a lower concentration of trans-zeatin-riboside and scopoletin. The characteristics associated to water irrigation did not influence negatively the development of any of these species, which confirms the use of brine as an alternative to irrigate them with conventional waters.

Atriplex species are prospective natural candidates for possible drug development because of their antioxidant, antibacterial, antiviral, anti-diabetic, anti-cancer, molluscicidal and antifungal properties. These pharmacological actions are associated to the presence of valuable biochemicals such as terpenoids, hydroxyecdysone, flavonoids and phenolics. These plants also have nutritional properties being rich source of proteins, vitamin A, vitamin C, flavonoids and amino acids. The proper utilization of the substances obtained from these plants can enhance the finesse of these abilities. Atriplex species are used as conventional cure of diseases due to their exceptional therapeutic uses. Plants of this genus have been employed by the common folk in several regions of the world to treat diabetes, jaundice, thyroid and liver disorder, snake bite and against infections in digestive, respiratory and urinary tract which indicate the worth of the herbs belonging to the genus Atriplex. These plants are not only medicinally important but are also important to boost economy specifically due to insecticidal properties of some species which make them suitable to be used for insecticidal applications in agriculture. In view of the medicinal and scientific uses along with the bioavailability of precious chemicals of Atriplex species, a comprehensive review is compiled which focuses on the detailed profile of chemicals present, medicinal uses of extracts, pharmacological functions and biological activities of Atriplex species so as to correlate the available data and explore their potential uses in all possible aspects.

Objective: The present study was designed to estimate the preventive and curative potency of aqueous extract of Atriplex halimus L. (Ah) aerial parts against benzene (BZ) intoxication in liver rats. Methods: 30 male albino rats were divided into five groups of 6 rats each: Control, Ah, BZ, AhP+BZ, and BZ+AhC. BZ (100 mg/kg b.w) was added in drinking water for 15 weeks. Aqueous extract of Atriplex halimus was received intragastrically during the last 30 days of BZ exposure for curative treatment (AhC) and all the duration of BZ exposure for preventive treatment (AhP). At the end the experiment, body weight gain and relative liver weight were estimated and liver enzyme markers (AST, ALT, ALP and LDH) were analysed by spectrophotometry. Histopathological studies on hepatic tissue were also performed by the method of Hematoxylin and Eosin staining. Results: Benzene administrated to rats caused an alteration in physiological parameters (body and organs weigh) and hepatic enzymes markers (AST, ALT, ALP and LDH). In addition, Histopathological studies showed a massive degeneration in liver tissue in BZ-exposed rats. However, treatment by Atriplex halimus especially preventive effect ameliorated most of the adverse effects induced by benzene. Ah restored the altered of physiological, biochemical and histopathological changes. Conclusion: The present study suggests that Atriplex halimus extract could be a substantially promising hepatoprotective agent against benzene toxic effects and may be against other hepatotoxic chemical or drugs. Keywords: Atriplex halimus, Benzene, hepatotoxicity, Rats.

The purpose of this work is to study the antioxidant and antibacterial activity of two plants of the same species « Atriplex halimus » from two different regions El Oued and Tlemcen. The plant leaves were subjected to a one-hour reflux extraction in methanol/acetone (70/30: v/v). Qualitative phytochemical examination of the leaf extract showed the presence of alkaloids, tannins and flavonoids of varying intensity. Coumarins, terpenoids and saponins are absent in both plants. Qualitative analysis of total polyphenols, flavonoids and condensed tannins of extracts shows that Atriplex halimus from the El Oued region has a high content of total polyphenols (10.25 ± 1.17 mg GAE/g DW) and tannins (9.23 ±1.09 mg EC/g DW) compared to Tlemcen. However, the high flavonoid content presented by Atriplex halimus from the Tlemcen region (3.09 ± 0.13 mg EC/g DW). The evaluation of the antioxidant activity of the extracts was carried out by three methods: total antioxidant capacity, trapping of the free radical DPPH and iron reducing power, the results obtained show that the extract of Atriplex halimus from Tlemcen reveals an interesting activity compared to that of El Oued with a CI50 = 193.47 ± 1.79µg/mL. Evaluation of antibacterial activity showing that El Oued extract has activity against Salmonella typhimirium ATCC 13311, Enterobacter cloacae ATCC 13047, Staphylococcus aureus ATCC 6538 and Listeria monocytogenes ATCC 15313 with a CMI value of 5 mg/mL, 10 mg/mL and 2.5 mg/mL respectively. However, Atriplex halimus from Tlemcen does not reveal any antibacterial activity against the strains tested.

Streszczenie:

The first treatment of the family Chenopodiaceae for the flora of Nepal (Central and Eastern Himalaya) has been recently published (Sukhorukov & Kushunina 2014). However, after a detailed investigation of original material concerning Chenopodium pallidum Moquin-Tandon (1840: 30), which is a part of Jacquemont’s collection from India (Herbarium P), we can state that all these specimens indeed belong to Atriplex Linnaeus (1753: 1052). The morphological differences between Atriplex and Chenopodium Linnaeus (1753: 218) are clear in mature plants only, whereas the plants in the type material were gathered in vegetative or early blooming stage (with flower buds only). This explains why the specimens have remained misidentified for such a long time. The characters which support our statement are: (1) Kranz leaf anatomy, which is typical of many Atriplex species (Sukhorukov 2006) placed into the large ‘C4-clade’ (Kadereit et al. 2010), but never observed in Chenopodium, (2) unisexual flowers (only male flower buds were found, because female flowers are absent at early blooming stage) which of all Chenopodieae in its current circumscription are present only in Atriplex (Sukhorukov & Zhang 2013). The “Eastern India” (Fr.: “Indes Orientales” after Jacquemont, 1834), where the plants were collected, applies to the territories of present-day West Bengal, Uttar Pradesh, Delhi, Rajasthan (northern part), Uttarakhand, Himachal Pradesh, Jammu & Kashmir, Punjab (India, Pakistan), and bordering parts of Xizang (China). Only some Atriplex species with Kranz leaf anatomy occur in this region (Zhu et al. 2003, Klimeš & Dickoré 2005, Sukhorukov 2006), such as: A. centralasiatica Iljin (1936: 124), A. pamirica Iljin (1936: 124), and A. schugnanica Iljin (1936: 123). However, the plants known as A. schugnanica are the best match to the Jacquemont’s specimens due to aphyllous or bracteose (not leafy) inflorescence. According to Art. 11 of ICN (McNeill et al. 2012), the name Chenopodium pallidum appears to be an older name at specific rank for Atriplex schugnanica Iljin (1936: 123), and thus a new combination is proposed in the present paper. Besides, new Chenopodium species, previously named Chenopodium pallidum, is described from Nepal.

Atriplex nummularia L. (atriplex) foliage and urea-treated straw have been used as nitrogen supplements for Barbarine lambs given Opuntia ficus-indica f. inermis (cactus) and their effects on feed intake, diet apparent digestibility, nitrogen balance and daily gain have been evaluated. Twenty-four lambs (mean live weight 19·9±2·79 kg) were randomly allocated to one of four experimental groups, groups 1–3 received freshly cut pads of cactus ad libitum. Group 1 was supplemented with 600 g untreated barley straw (C+US), while group 2 received 600 g urea-treated straw (C+UTS). Group 3 received 600 g untreated straw and 400 g atriplex (C+A). The amount of atriplex was calculated so that groups 2 and 3 receive iso-nitrogenous diets (i.e. C+UTS and C+A). Group 4 (US+BW) received a diet commonly offered to sheep by Tunisian smallholders, untreated straw ad libitum and 400 g of ground barley grain and wheat bran mixture (50[ratio ]50). A growth trial (60 days) followed by a digestibility trial (8 days) were performed in 1999. Irrespective of dietary treatment, cactus intake was high, averaging 500 g dry matter (DM)/day. It was not affected (P>0·05) with N supplementation, as urea-treated straw or atriplex. Sheep fed cactus-containing diets drank considerably less (P<0·001) water than those on the common diet (US+BW). Nitrogen provision improved significantly apparent digestibility of cactus-based diets. Urea treatment of straw increased content of digestible dry matter, organic matter, crude protein and cell wall (NDF) by 100, 100, 120 and 290 g/kg diet, respectively. There was a further increase when atriplex was provided instead of urea-treated straw. Nitrogen balance was positive across all dietary treatments but was improved when the nitrogen content of cactus-based diets was increased. Sheep fed on cactus and supplemented with atriplex retained the same amount of N as those fed the common diet (US+BW). The efficiency of microbial N production, estimated by the urinary excretion of allantoin, was improved (P<0·05) with N supplementation of cactus-diets (5·7, 12·4 and 11·4 mg/kg digestible OM intake for diets C+US, C+UTS, C+A, respectively). The diet C+US covered maintenance requirements of the sheep (7·7 g of daily gain). Nitrogen supplementation of cactus-based diets raised the average daily gain of lambs. Indeed, sheep given C+UTS or C+A diets grew at a rate of 19·9 or 31·4 g/day, respectively. It is noteworthy to mention that C+A and US+BW diets had similar effect (P>0·05) on sheep growth (31·4 and 39·7 g/day, respectively). It is concluded that cactus may be considered as an emergency feed and water source for sheep in arid and semi-arid zones. Nitrogen supplementation of cactus-based diets with urea-treated straw or atriplex foliage improved the feeding value of these diets and consequently sheep growth. A cactus-based diet, supplemented with atriplex, promoted similar growth in sheep as the commonly used diet (US+BW).

Desenvolveu-se este trabalho em um Cambissolo salino sódico do Perímetro Irrigado Cachoeira II, Serra Talhada, PE, com o objetivo de avaliar a dinâmica de cátions e ânions básicos em um solo salino sódico submetido a fitorremediação com Atriplex nummularia e correção com aplicação de gesso. Realizaram-se amostragens semestrais com quatro coletas de solo (0, 6, 12 e 18 meses). O delineamento experimental utilizado foi de blocos ao acaso avaliando-se quatro tratamentos: controle (sem nenhum manejo do solo), correção química com gesso (sem cultivo) e dois com cultivo de Atriplex nummularia Lindl (espaçamentos 1 x 1 m e 2 x 2 m), com quatro repetições. Os resultados das análises do solo revelaram a contribuição da aplicação de gesso, especialmente do cultivo de plantas de atriplex na redução dos teores de sais no solo.

Seed germination of desert shrubs (Atriplex griffithii Moq., Haloxylon recurvum (Moq.) Bunge ex Boiss, Suaeda fruticosa (L.) Forssk., Triglochin maritima L.), and a forb (Zygophyllum simplex L.) was studied under various light, temperature, and salinity regimes. Seed germination of Atriplex griffithii, Z. simplex, and Suaeda fruticosa was least affected by light, whereas, seeds of H. recurvum and T. maritima had a light requirement for germination. Haloxylon recurvum seeds did not germinate at 10–20 °C in the dark, and no T. maritima seeds germinated in dark at all thermoperiod and salinity regimes studied. Seed germination was inhibited in all species with an increase in salinity, and this inhibition was more substantial in dark than in light. Key words: Atriplex griffithii, halophyte, Haloxylon recurvum, light, seed germination, Suaeda fruticosa, Triglochin maritima, thermoperiod, Zygophyllum simplex.

Streszczenie:

The current study reports effects of salt stress on growth, K+ nutrition and organic composition of Atriplex nummularia. The upper limit of the NaCl gradient imposed on the plants was close to seawater salinity (600 mM). An external NaCl of 150 mM improved the growth of this species, which corroborates its halophytic nature. Evidence show that Atriplex nummularia was responsive to NaCl, but the mechanisms of this response are still not known. In such stress condition, Na+ and Cl- accumulation in leaves was far greater than that in roots; therefore salinity tolerance of Atriplex nummularia is not due to ion exclusion mechanism. In spite of a reduction of K+ content of tissues under salinity conditions, no corresponding physiological relevance of this in terms of growth was found. The high affinity of root cells for Na+ during uptake and, probably, its subsequent sequestration into cell vacuoles and structures of protection seems to contribute to osmotic adjustment as an increase in relative water content (RWC) of leaves was observed. NaCl caused a decrease in total soluble proteins and chlorophylls; the relevance of this is discussed in terms of mechanisms of salinity tolerance. The ability of Atriplex nummularia plants to keep Na+ and Cl- away from enzymes and cytosolic structures, together with an effective osmotic adjustment, is suggested as having a role in its tolerance to high salinity.

Â This study examined the influence of salt levels on antioxidant activity and content of carotenoids and anthocyanins of the A. hortensis leaves using two varieties: green orach (var. purpurea ) and red orach (var. rubra). Seeds of Atriplex were exposed to 0, 90, 180 and 260 mM NaCl for 3 months and seeds were sown in an earthen pot. Overall levels of ascorbate peroxidase (APX) and glutathione reductase (GR) activity were significantly elevated. Salt stress caused a significant decline in tissue concentrations of catalase (CAT) and superoxide dismutase (SOD). However, 90 mM NaCl did not modify these parameters, which remains similar to control values. Activities of APX and CAT were increase whether the shoots of A. hortensis var. purpurea were grown in the presence of 180 mM NaCl. Thus although some indications of oxidative stress accompany exposure of this salt-tolerant Atriplex varieties to salinity, mechanisms appear to exist within its shoot tissue to permit the tolerance of such oxidative stress. High salt concentration in the culture medium provokes oxidative damage in Atriplex leaves and induces a general increase in antioxidant enzyme activity. In particular, NaCl toxicity decreased content of carotenoids. It also decreased the concentration of anthocyanin pigments in leaves of Atriplex. This work therefore provides a starting point towards a better understanding of the role of antioxidant enzyme in the plant response against salt stress.
