“…The epidermis is the most external cellular layer whose characters are under gene control and is influenced to some extend by environmental factor (El-Ghamery et al, 2017). Bio systematically, foliar epidermal characters such as size and shape of stomatal complex, their placement, structural specialties of epidermal cell walls, and typical forms of trichomes help in the identification of many plant families (Chaudhari et al, 2014;Özdemir et al, 2016).…”

“…The same results were reported by other investigators. They noted the maximum growth of plants in the period between formation of inflorescences and flowering (Abbas et al, 2017;Carlquist, 2003;Archipova & Breus, 2004). It was determined that the daily increase in plant height was 5 cm in the flowering stage and 2 cm throughout the growing season.…”

Comparative study of amaranth species (Amaranthus spp.) in the temperate continental climate of Russian FederationAbstract: Field experiments were carried out in the Chuvash Republic, which is located in the center of the European part of Russia on the banks of the Volga River and has a moderately continental climate with warm summers, cold winters, well-defined transitional seasons and average annual rainfall of 500 mm. There are many cultural and wild species of amaranth in nature, differing in morphological and biological features. The objects of research were four common species of amaranth (Amaranthus spp.): A. cruentus L., A. caudatus L., A. hybridus L., A. spinosus L.. Particular attention in the experiment was paid to the morphological and biological characteristics of plants according to the growth stages during growing season and the formation of the yield of green mass and grain during 3 years of research. As a result of the experiment, the possibility of cultivating a heat-loving amaranth culture in the climatic conditions of the Chuvash Republic was proved and adaptive species for growing green mass (A.cruentus and A.caudatus) and for grain (A.cruentus) were identified. Primerjalna raziskava vrst ščira (Amaranthus spp.) v zmernem kontinentalnem podnebju Ruske FederacijeIzvleček: Poljski poskus je bil izveden v Čuvaški republiki, v osrednem delu evropskega dela Rusije, na bregovih Volge, ki ima zmerno kontinentalno podnebje s toplimi poletji, mrzlimi zimami, z dobro izraženimi prehodnimi obdobji in s povprečno letno količino padavin 500 mm. Na območju uspeva več gojenih in podivjanih vrst ščira z različnimi morfološkimi in biološkimi lastnostmi. Predmet raziskave so bile štiri pogoste vrste ščira: A. cruentus L., A. caudatus L., A. hybridus L., A. spinosus L.. Posebna pozornost je bila posvečena morfološkim in biološkim lastnostim rastlin glede na fazo v rastni sezoni, tvorbi biomase in zrnja v 3 letih raziskav. Kot rezultat poskusa je bila dokazana možnost gojitve toploljubnih ščirov v klimatski razmerah Čuvaške republike, za zeleno biomaso vrsti A.cruentus and A.caudatus in za zrnje vrsto A.cruentus.

“…Previous studies have shown that the taxonomic classification of Amaranthus can be confusing, as it relies on few characteristics to distinguish species from each other (Sauer, 1950(Sauer, , 1967. El-Ghamery et al ( 2017) evaluated 38 leaf anatomical characteristics in the genus Amaranthus and proposed eight identification keys (El-Ghamery et al, 2017). However, species identification based on these anatomical features requires specialized skills to prepare the samples.…”

Amaranth species (Amaranthus spp.) serve as pseudo cereals and also as traditional leafy vegetables worldwide. In addition to high vigor and richness in nutrients, drought and salinity tolerance makes amaranth a promising vegetable to acclimatize to the effects of global climate change. The World Vegetable Center gene bank conserves ∼1,000 amaranth accessions, and various agronomic properties of these accessions were recorded during seed regeneration over decades. In this study, we verified the taxonomic annotation of the germplasm based on a 15K single‐nucleotide polymorphism (SNP) set. Given that the yield components of grain amaranth are different from those of leaf amaranth, we observed that grain amaranth species presented larger inflorescences and earlier flowering than leaf amaranth species. Dual‐purpose amaranth showed larger leaves than leaf amaranth and later flowering than grain amaranth, which seemed reasonable because farmers can harvest more leaves during the prolonged vegetable stage, which also provides recovery time to enrich grain production. Considering frequent interspecific hybridization among species of the grain amaranth complex, we performed an interspecific genome‐wide association study (GWAS) for days to flowering, identifying a AGL20/SOC1 homolog. Another GWAS using only A. tricolor L. accessions revealed six candidate genes homologous to lba1, bri1, sgs1, and fca. These homologous genes were involved in the regulation of flowering time in Arabidopsis thaliana (L.) Heynh. This study revealed the usefulness of genotypic data for species demarcation in the genus Amaranthus and the potential of interspecific GWAS to detect quantitative trait loci (QTL) across different species, opening up the possibility of targeted introduction of specific genetic variants into different Amaranthus species.
