Floral Variety Of Fabaceae Lindl. Family In Gully Ecosystems In The South-West Of The Central Russian Upland

Abstract

Federal and regional centre for aerospace and surface monitoring of the objects and natural resources, ABSTRACTThe multi-year geobotanical studies have shown that in the south-west of the Central Russian Upland the fl oristic composition of gully ecosystems includes 274 genera, which are combined into 65 families. The species from 3 families: Asteraceae Dumort., Fabaceae Lindl. and Poaceae Barnh. take the lead in the taxon hierarchy. The value of the generic coeffi cient, which is calculated by the number of species per genus, is quite signifi cant and is equal to 1.81. It has been established that Fabaceae Lindl. species have extensive presentation (it comes second place in the fi rst triad of families). Among Fabaceae species, a particular importance is given to wild related cultural species, which have high biological, and resource value by a mix of morphological and qualitative characteristics and which are potential selection sources for improvement of various economically useful features. The most striking example include species of the Medicago: Medicago sativa L. genus and the Medicago var Mart. hybrid genus. The M. sativa L. and M. varia Mart. coenopopulations in gully mouths are the most complete and they often have continuity of species distribution by age groups. It has been found that any forms, which act as carriers of multidimensionality recessive mutation, i.e. mf-mutation, have a 203 high degree of occurrence in local populations. With seed renewal, the proportion of species with mf-mutation is from 5 to 55% in families (the offspring of the fi rst plant). The M. sativa L. and M. varia Mart. forms, which have been identifi ed by us in the natural habitats of gully geocomplexes, have a number of valuable selection crop-related characteristics: high seed production, good leaf coverage and high protein content.

“…The methodological basis of the research was the theory of the formation of a secondary anthropogenic Microgen center of formation in the South of the Central Russian upland [20][21][22]. The study of the species was conducted for three years on the territory of Veidelevsky and Krasnogvardeisky districts.…”

Scots Pine (Pinus sylvestris L.) Ecotypes Response to Accumulation of Heavy Metals during Reforestation on Chalk Outcrops

“…Figure 1 shows the profile of soddy-calcareous soil on the eluvium-chalk parent rock in the ravine-gully complex. The specificity of the substrate determines the endemism and specificity of plants capable of growing under poor development conditions [23][24][25]. In this regard, the forest reclamation measures require a special approach in the choice of forest crops, cultivation technologies, and approaches to the study of factors affecting the growth and development of forest crops, especially in the early stages of development.…”

“…However, the issue of the seed reproduction of Scots pine (P. sylvestris) ecotypes in culture and during self-recovery on chalk outcrops has not been sufficiently studied [37][38][39]. Particular attention should be paid to the regulation of tree growth and development processes at the initial stages of ontogenesis, starting from seed The specificity of the substrate determines the endemism and specificity of plants capable of growing under poor development conditions [23][24][25]. In this regard, the forest reclamation measures require a special approach in the choice of forest crops, cultivation technologies, and approaches to the study of factors affecting the growth and development of forest crops, especially in the early stages of development.…”

Using Microorganismal Consortium and Bioactive Substances to Treat Seeds of Two Scots Pine Ecotypes as a Technique to Increase Re-Afforestation Efficiency on Chalk Outcrops

“…The hard and rocky chalky substrate, barely touched by soil formation processes, is found to possess some adverse properties, i.e., it has a strict light and water regime, high albedo, and high physiological dryness [16][17][18]. This kind of chalky outcrop substrate is suitable for the growth of an insignificant number of highly stenoecious organisms-endemic and specific in terms of nutritional adaptation species (Figure 2) [19][20][21]. Landscape complexes with carbonate rock outcrops are quite widespread worldwide; calcareous outcrops in the steppe, semi-desert, and desert zones of Eurasia hold a special place [22,23].…”
