    The purpose was to compare the sensitivity of the Allium test with the other plant assays. As micronuclei in interphase cells have been discussed as an alternative endpoint to chromosome aberrations in the anaphase–telophase cells, we have also included the scoring of micronuclei in the present study. 2.

The active ingredients of fungicide were mefenoxam in 5% w/w proportion and copper hydroxide in 60% w/w proportion. The plant used as test material was Allium cepa L. (2n= 16). Three.

The most common basic chromosome number in Allium is x = 8, but other numbers (x=7, 9, 10, 11) andCited by: 3. The genus Allium is one of the largest in the world flora.

This genus also contains several other species variously referred to as onions and cultivated for food, such as the Japanese bunching Clade: Tracheophytes.

If there are any changes from the normal diploid number, like loss or addition of one or two chromosomes leads to Aneuploidy. Allium, (genus Allium), large genus of onion- or garlic-scented bulbous herbs of the amaryllis family (Amaryllidaceae).

Allium species are found in most regions of the world except the tropics and New Zealand and Australia. Several are important food crops, including the onion (Allium cepa), garlic.

Populations of Allium schoenoprasum, 2n=16, from six of the eight British localities have been examined. A B-chromosome polymorphism has been found which is limited to the River Wye, South Wales, where A. schoenoprasum grows along a 15 kilometre stretch.

Four interrelated types of small, euchromatic, mitotically-stable B-chromosomes by: The common garlic, Allium sativum L. (2n=16), occurs basically as three morphotypes-H, U and A types (Table 1), all exclusively vegetatively reproduced. Five karyotypes from five bulbs of the A type have been analysed in detail to make a case study to discover if there is any necessity for extensive observations on a wide variety of by:   Plants produce and emit important volatile organic compounds (VOCs), which have an essential role in biotic and abiotic stress responses and in plant–plant and plant–insect interactions.

In order to study the bouquets from plants qualitatively and quantitatively, a comprehensive, analytical method yielding reproducible results is required. We applied in-tube extraction (ITEX) and solid Cited by: 1. Introduction. Numerous potentially mutagenic chemicals have been studied mainly because they can cause damaging and inheritable changes in the genetic material, without being immediately expressed (Vogel, ).In order to identify the harmful effects of substances in different concentrations and times of exposure, a variety of tests have been employed, such as cytogenetic by: of cystine sulfoxides.

Allium contains many economically important crop and ornamental species, including onion (Allium cepa), garlic (A. sativum), leek (A. ampeloprasum), and chive (A. schoenoprasum). Allium is naturally distrib-uted throughout the Northern Hemisphere and is repre-sented by ca.

species worldwide (Stern, )withca. (Allium cepa L.). Larvae and adults live in the leaf sheath and stalk, sucking up the contents of plant cells, causing a series of damages to the crop and thus severely affecting onion production (MOUND; MARULLO, ; PALMER et al., ). tabaci is controlled mainly by means of chemical products, but their efficiency in the control.

The chromosome numbers of 46 BC 2 seedlings varied from 16 to Eight monosomic additions (2 n = 2 x +1 = 17, AA+nF) and 20 single-alien deletions were found in these BC 2 seedlings. Conse-quently, six kinds of A. cepa – A. fistulosum alien chromosome additions possess-ing different chromosome.practice.

Leaf tissue was sampled from the youngest fully expand-ed leaf of developing plants on 21 December prior to initia-tion of bulbing and on 13 January after commencement of bulbing.

Leaf blades and base tissue were frozen at °C and freeze-dried. These samples were analysed for sucrose synthase activity.Allium bigelovii, the New Mexico wild leek, is a plant species native to Arizona and southwestern New Mexico.

It grows on open, gravelly slopes at elevations of –1, m (1,–5, ft). The specific epithet honors John Milton Bigelow (based on the Latinized form of his surname, Bigelovius). Allium bigelovii has spherical bulbs about 15 mm ( in) in : Amaryllidaceae.
