  • Amaranth Seed Oil Composition Parisa Nasirpour-Tabrizi, Sodeif Azadmard-Damirchi, Javad Hesari and Zahra Piravi-Vanak
    Chapter Amaranth Seed Oil Composition Parisa Nasirpour-Tabrizi, Sodeif Azadmard-Damirchi, Javad Hesari and Zahra Piravi-Vanak Abstract In this chapter, amaranth seed oil composition will be presented. The main component of this oil is triacylglycerols (TAGs). TAGs are composed of fatty acids, which have an important effect on oil stability, application, and nutritional proper- ties. POL, PLL, POO, OLL, and LOO are the predominant TAGs in the amaranth seed oil. Linoleic acid (C18:2), oleic acid (C18:1), and palmitic acid (C16:0) are the predominant fatty acids present in the amaranth oil. Minor components of this oil are squalene, sterols, tocopherols, carotenoids, phospholipids, etc. Growth condi- tions of amaranth and extraction conditions can influence oil composition, which will be discussed in this chapter as well. Oil stability and quality parameters will be also discussed. The stability of this oil during different conditions of storage will be a part of this chapter. Keywords: triacylglycerol, fatty acid, squalene, tocopherol, sterol 1. Introduction Grain amaranth is considered as a gluten-free pseudocereal, which is a non-grass but cereal-like grain (true cereals are classified as grasses). It is suitable to be used as the celiac disease patient diet as it contains no gluten [1]. Among more than 60 spe- cies, the grain of Amaranthus caudatus, Amaranthus hypochondriacus, Amaranthus cruentus, Amaranthus hybridus, and Amaranthus mantegazzianus can be used as flour in some industries, such as bakery and confectionery. However, species of Amaranthus retroflexus, Amaranthus viridis, and Amaranthus spinosus are not safe to be consumed [2]. The amaranth grain is mainly composed of about 61.3–76.5% carbohydrate (mostly starch), 13.1–21.5% crude protein, 5.6–10.9% crude fat, 2.7–5% crude fiber, and 2.5–4.4% ash [3].

The following forms of the genus were taken under consideration: cultivated amaranth (A. cruentus) and a wild form (A. retroflexus) growing as a weed on amaranth and sugar beet plantations and growing as a ruderal weed. The aim of the work was to determine which fungi communities occur in the phyllosphere, roots, rhizoplane, and rhizosphere of Amaranthus spp. To investigate the phyllosphere fungi communities, 5 plants were taken in the seed formation phase. From each plant, 3 healthy, symptomless leaves were taken. In addition, the isolation of fungi communities from the roots, rhizoplane, and rhizosphere was performed in the seed formation phase. Ten plants from each location were taken along the diagonal of the plot. In total, 38 species of fungi were isolated from the phyllosphere of Amaranthus spp., and of that number, 30 were collected from A.

(Amaranthaceae). Th e species is a noxious weed introduced in Italy from North America. It exhibits a high phenotypic plasticity and easily adapts to a multitude of agricultural and ruderal habitats. A. retrofl exus has variable degrees of dormancy and germination rates as a result of environmental factors. Growth is rapid and plants produce a large number of viable seeds. Th e species has developed resistance to several herbicides and other chemicals. It is alternate host to nematodes, viruses, bacteria and fungi that usually aff ect cultivated plants.

Essential oils properties such as antioxidant, antimicrobial and anti-inflammatory activities are known for a long time and hence widely used in traditional medicines, cosmetics and food industries. However, despite their effects against many phytopathogenic fungi, oomycetes and bacteria as well as weeds, their use in agriculture remains surprisingly scarce. The purpose of the present review is to gather and discuss up-to-date biological activities of EO against weeds, plant pathogenic fungi, oomycetes and bacteria, reported in the scientific literature. Innovative methods, potentially valuable to improve the efficiency and reliability of EO, have been investigated. In particular, their use towards a more sustainable agriculture has been discussed, aiming at encouraging the use of alternative products to substitute synthetic pesticides to control weeds and plant diseases, without significantly affecting crop yields. An overview of the market and the recent advances on the regulation of these products as well as future challenges to promote their development and wider use in disease management programs is described.

  • Allelopathy: How Plants Suppress Other Plants1 James J

Chase2 What Is Allelopathy? weed-free zones, and other related changes in vegetation patterns. Our purpose here is to introduce the concept Allelopathy refers to the beneficial or harmful effects of of allelopathy, to cite specific examples, and to mention one plant on another plant, both crop and weed species, potential applications as an alternative weed management from the release of biochemicals, known as allelochemicals, strategy. from plant parts by leaching, root exudation, volatilization, residue decomposition, and other processes in both natural and agricultural systems. Allelochemicals are a subset Nature of Allelopathy of secondary metabolites not required for metabolism Commonly cited effects of allelopathy include reduced seed (growth and development) of the allelopathic organism. germination and seedling growth. Like synthetic herbicides, Allelochemicals with negative allelopathic effects are an there is no common mode of action or physiological target important part of plant defense against herbivory (i.e., site for all allelochemicals. However, known sites of action animals eating plants as their primary food) (Fraenkel 1959; for some allelochemicals include cell division, pollen Stamp 2003). germination, nutrient uptake, photosynthesis, and specific enzyme function. For example, one study that examined The term allelopathy is from the Greek-derived compounds the effect of an allelochemical known in velvetbean, allelo and pathy (meaning “mutual harm” or “suffering”) 3-(3’,4’-dihydroxyphenyl)-l-alanine (l-DOPA), indicated and was first used in 1937 by Austrian scientist Hans that the inhibition by this compound is due to adverse Molisch in the book Der Einfluss einer Pflanze auf die effects on amino acid metabolism and iron concentration andere - Allelopathie (The Effect of Plants on Each Other) equilibrium.
