Abstract: Dogs and cats are the animals that owners most frequently seek assistance for potential poisonings, and these species are frequently involved with toxicoses due to ingestion of poisonous food. Feeding human foodstuff to pets may prove itself dangerous for their health, similarly to what is observed in Allium species toxicosis. Allium species toxicosis is reported worldwide in several animal species, and the toxic principles present in them causes the transformation of hemoglobin into methemoglobin, consequently resulting in hemolytic anemia with Heinz body formation. The aim of this review is to analyze the clinicopathologic aspects and therapeutic approach of this serious toxicosis of dogs and cats in order to give knowledge to veterinarians about Allium species toxicosis, and subsequently allow them to correctly diagnose this disease when facing it; and to educate pet owners to not feed their animals with Allium- containg food in order to better control this particular life-threatening toxicosis. Key words: Allium spp., poisonous plants, hemolytic anemia, Heinz bodies. INTRODUCTION differentiate them from other morphologically similar poisonous plants (6, 7).

(Latin cepa = onion), also known as the bulb onion or Onion common onion, is a vegetable and is the most widely cultivated species of the genus Allium. This genus also contains several other species variously referred to as onions and cultivated for food, such as the Japanese bunching onion (A. fistulosum), the Egyptian onion (A. ×proliferum), and the Canada onion (A. canadense). The name "wild onion" is applied to a number of Allium species, but A. cepa is exclusively known from cultivation. Its ancestral wild original form is not known, although escapes from cultivation have become established Scientific classification in some regions.[2] The onion is most frequently a biennial or a perennial plant, but is usually treated as Kingdom: Plantae an annual and harvested in its first growing season.

  • Southern Plant Lists
    Southern Plant Lists Southern Garden History Society A Joint Project With The Colonial Williamsburg Foundation September 2000 1 INTRODUCTION Plants are the major component of any garden, and it is paramount to understanding the history of gardens and gardening to know the history of plants. For those interested in the garden history of the American south, the provenance of plants in our gardens is a continuing challenge. A number of years ago the Southern Garden History Society set out to create a ‘southern plant list’ featuring the dates of introduction of plants into horticulture in the South. This proved to be a daunting task, as the date of introduction of a plant into gardens along the eastern seaboard of the Middle Atlantic States was different than the date of introduction along the Gulf Coast, or the Southern Highlands. To complicate maters, a plant native to the Mississippi River valley might be brought in to a New Orleans gardens many years before it found its way into a Virginia garden. A more logical project seemed to be to assemble a broad array plant lists, with lists from each geographic region and across the spectrum of time. The project’s purpose is to bring together in one place a base of information, a data base, if you will, that will allow those interested in old gardens to determine the plants available and popular in the different regions at certain times. This manual is the fruition of a joint undertaking between the Southern Garden History Society and the Colonial Williamsburg Foundation. In choosing lists to be included, I have been rather ruthless in expecting that the lists be specific to a place and a time.

The 20 species are described in turn; they comprise 4 wild species, T. aegilopoides, T. urarthu (2n = 14), T. dicoccoides and T. chaldicum (2n = 28) and 16 cultivated species.

  • Shallots in Croatia – Genetics, Morphology and Nomenclature
    Acta Bot. Croat. 72 (2), 387–398, 2013 CODEN: ABCRA25 ISSN 0365–0588 eISSN 1847-8476 DOI: 10.2478/botcro-2013-0016 Review paper Shallots in Croatia – genetics, morphology and nomenclature JASNA PUIZINA* University of Split, Faculty of Science, Department of Biology, Teslina 12, 2100 Split Abstract – The term 'shallot' in Croatia denotes three genetically and morphologically different, vegetatively reproduced relatives of the common onion, Allium cepa L., which are mainly traditionally cultivated for consumption and as a spice: A. cepa Aggregatum group, (2n =2x = 16), A. × proliferum (Moench) Schrad. (2n =2x = 16) and A. × cornutum Clementi ex Vis. (2n =3x = 24). This paper reviews the results of studies of their morpho- -anatomical characteristics and genetic structure. Although all three taxa were determined as varieties of the common onion, only the shallot A. cepa Aggregatum group (syn. A. ascalonicum L.) belongs to that species. The shallot A. × proliferum represents a hybrid between the two closely related species, A. cepa and A. fistulosum L. The third form of shallot, A.×cornutum is a still incompletely understood triploid hybrid between A. cepa and one or two closely related Allium species, whose identity has not been fully elucidated. In contrast to shallot A. cepa Aggregatum group, which has normal meiosis and produces fertile seed, hybrid shallots A. × proliferum and A. × cornutum are sterile, and reproduce exclusively vegetatively by underground bulbs or bulbils from the inflorescence. Key words: Allium cepa, shallot, hybrid, polyploidy, triploid viviparous onion, top onion, karyotype, genome, meiosis Common onion, Allium cepa L. The genus Allium comprises about 750 species distributed all over the northern hemi- sphere except for its tropical regions (STEARN 1992, FRITCH and FRIESEN 2002).

  • Daf Ditty Eruvin 29- Onion Johnny
    Daf Ditty Eruvin 29: Onion Johnny We are all as delicate as onions. Outside, pinkish-brown, striated with age, our dried up, papery carapace ready to be peeled away to expose new skin beneath. Tears flow as I remove each layer, tough becoming ever more soft, richer in aroma and paler in hue. Then the tender centre, the unblemished flesh like that of a new-born child - the child I yearn to hold in my arms. The Onion Johnny by Yvonne Clark1 1 https://www.londonindependentstoryprize.co.uk/post/the-onion-johnny 1 2 The Master also said that the minimum measure of olives and onions that may be used for an eiruv is enough to eat them with the food of two meals. The Gemara asks: May one establish an eiruv with onions? Wasn’t it taught in a baraita that Rabbi Shimon ben Elazar said: Rabbi Meir once spent Shabbat in the town of Ardiska, and a certain person came before him and said to him: Rabbi, I made an eiruv of Shabbat borders [eiruv teḥumin] with onions, so that I might walk to the town of Tiv’in. 3 Ardiska was located between the man’s eiruv and his destination of Tiv’in, which was beyond his Shabbat limit as measured from his hometown. And Rabbi Meir made him remain within his four cubits. He forbade him to leave his four cubits, as he held that an eiruv made with onions is not an eiruv, and therefore the person had left his Shabbat limit without an eiruv teḥumin.

  • Tree Onion Cultivation
    TREEONIONS.COM Tree Onions Botanical Name: Allium cepa proliferum Common Names: Tree Onions, Top Onions, Topset Onions, Top Setting Onions, Walking Onions, Egyptian Walking Onions, Air Onions Description: The tree onion is a biennial plant meaning it should usually flower in its second year. However, you will find it produces small onion bulbs at the base of the plants and a multitude of small top sets where a flower should be. The number and size of bulbils can vary significantly between about 3 large top set onions and 15 smaller sets. The parent onion behaves as a multiplier or shallot and can split to produce several small tender onions that can be eaten or regrown. Edible Uses: The top sets or bulbils are an ideal size for pickling or chopping into salads. The onion greens can be used just like spring onions The mature onions are tender and can be used raw or cooked like normal onions. Planting in the UK Planting Period: May to December. The tree onion is quite hardy but can certainly benefit from a top mulch or growing in an unheated greenhouse to protect from frosts until it becomes established Depth: Plant about 25mm (1 inch) deep Spacing: Allow about 15 to 20cm between plants (6 to 8 inches) Soil – Growing Medium: If growing in the ground, try and prepare the area in advance to produce a rich, free draining loam with a slow release, low nitrogen fertiliser. Tree onions can be grown in most composts but ensure they don't remain waterlogged or rotting of the bulb can occur.
