The cultural species in the process ontogenesis and phylogenesis to favorable and unfavorable environmental conditions produce a number of biological mechanisms (molecular genetic, physiological, biochemical, morphological, biocenotic), plants identification behind them reflects the degree of their ecological of adaptability, plasticity and stability. Studying the and comparison of morphological parameters and relations with consort-species and representatives of tribe Triticeae allowed to find out what plants differently realize their life potential. Which are based on structural and functional features biocenotic mechanisms that manifested in adaptive properties. On example cultural cereal species shows that the basic mechanisms of adaptability are: mechanisms of functional sustainability, morphological tolerance and ontogenetic avoidance. The first group is associated with functional parameters forming and manifestation life potential of plants (accumulation protein, accumulation gluten, duration assimilatory ability flag leaf; erection leaves the upper tier; depth of node tillering; strength of the stem, ie the, low penchant to lodging; total tillering plants; synchronicity growth of main stem; the intensity fading ear after full ripeness. The second group includes mechanisms of morphological tolerance (hairiness of leaves, stems; wax-colored bloom; plaza of leaf; type of bush; density head; beardedness; glossy coating of leaf, culm; glaucous color of leaf, culm; placing spicate of scales near granule; plant height). To mechanisms of ontogenetic avoidance relating such as mismatch of pathogen, phytophage and plant; photoperiodic sensitivity; duration interphase periods in particular florification, ripening; duration of vegetation period; duration of primary dormancy (latent period); multivariation of synontоgenesis; photoperiodic sensitivity. Knowing the biocenotic mechanisms formation of adaptability cultural species discloses up new opportunities in clarifying the fundamental bases of adaptation and is of practical importance in the management of vitality and seed productivity.

“…In the current study, eT counteracted any positive effects of eCO 2 on amino acid concentrations and aphid performance. Gaining a mechanistic understanding of how herbivorous insects are affected by different aspects of environmental change, individually and in combination, is therefore essential for both preventing pest outbreaks and understanding community dynamics (Hancock, Hogenhout & Foyer ; Simpson et al . ).…”

Climate and atmospheric change impacts on sap‐feeding herbivores: a mechanistic explanation based on functional groups of primary metabolites

Summary Global climate and atmospheric change are widely predicted to affect many ecosystems. Herbivorous insects account for 25% of the planet's species so their responses to environmental change are pivotal to how future ecosystems will function. Atmospheric change affects feeding guilds differently, however, with sap‐feeding herbivores consistently identified as net beneficiaries of predicted increases in atmospheric carbon dioxide concentrations (eCO2). The mechanistic basis for these effects remains largely unknown, and our understanding about how multiple environmental changes, acting in tandem, shape plant–insect interactions is incomplete. This study investigated how increases in temperature (eT) and eCO2 affected the performance of the pea aphid (Acyrthosiphon pisum) via changes in amino acid concentrations in the model legume, lucerne (Medicago sativa). Aphid performance increased under eCO2 at ambient temperatures, whereby aphid fecundity, longevity, colonization success and rm increased by 42%, 30%, 25% and 21%, respectively. eT negated the positive effects of eCO2 on both fecundity and rm, however, and performance was similar to when aphids were reared at ambient CO2. We identified discrete functional groups of amino acids that underpinned the effects of climate and atmospheric change, in addition to plant genotype, on aphid performance. Effects of eT and eCO2 held true across five M. sativa genotypes, demonstrating the generality of their effects. Combining this knowledge with amino acid profiles of existing cultivars raises the possibility of predicting future susceptibility to aphids and preventing outbreaks of a global pest. Moreover, environmentally induced changes in the nutritional ecology of aphids have the capacity to change life‐history strategies of aphids and their direct and indirect interactions with many other organisms, including mutualists and antagonists.

The most numerous and malicious types of pathogens fungal diseases of plants cultural cereals -Triticum аestivum L., Secale cereale L. та Triticum trispecies Shulind. in conditions of anthropical ecosystem Central Right-bank Forest-Steppe are Microdochium nivale (Fr.), Blumeria graminis (DC.) f. sp. tritici Speer, Puccinia recondita Rob. ex. Desm f. sp. tritici та Tillitia caries (Tul.), Tillitia secalis (Korda, Kuhn) etc., manifestation of parasitism depends on genotypical, phenotypical, ontogenetical peculiarities plants, growing conditions. According to the results of years of research (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) highlighted group of plant formsthat are characterized by mono-, two-and polyfacet of resistance epiphytoparasites. That peculiarity owning heterogeneous or multilinearity plant forms (Аriivkа, Yuvivata 60, КС 1, Л 3-95, Л 4639/96), formed as a result of hybridization and repeated bekrossing and selected from hybrid populations by means individual and mass selections. The mechanism of plant genetic heterogeneity of the aforementioned forms due to the presence of multivariate phenetical markers -components of the spectra gliadin proteins (6А1, 6А4, 6В1, 6В3 etc.), as well as the phenotypical and ontogenetical their homogeneity, which increases the resistance of plant populations to adverse biotic stress environment. Among the studied assortment varietal plants tribe Triticeae, medium higher stability of some of them to the spectrum specified above epiphytoparasites caused by their variety individuals, which, mass and individual selection as a result of the reproduction, give rise to whole families -point populations (manifesting different firmness to one and the same species and races of pathogens, including with progressive race creative process), that is the basis of formed varieties -as megapopulation. Adaptive mechanisms of plant populations cultural crops to adverse biotic stress, particularly damaging pathogens are a number of biological peculiarities (molecular genetics, physiological, biochemical, morphological, ontogenetic, biocenotic), identification of plants which reflects the degree of their adaptive ability, ecological plasticity and sustainability. In general, the mechanisms resistance of plant tribe Triticeae to epiphytoparasites can distinguish by the following types: functional stability (sustainability, is caused by peculiarities of functional parameters of the plant), morphological tolerance (the ability of plants to resist damage without reducing productivity), ontogenetic evasion (sustainability, is caused by peculiarities ontogenetic of development of plants), photoperiodic sensitivity (retarded the development in autumn and late spring vegetation) and genetic heterogeneity (the presence of morphologically identical homozygous of lines differing by the spectrum of component proteins gliadin). Plant forms that possess mono-and polyfacet resistance to epiphytoparasites avoid parasite influence of fungi due to the mechanism ontogenetic evasion (Slav...
