The provenances from the center area demonstrated a high adaptation capacity in the test site from the ,,Plaiul Fagului” reservation, having a signifi cant performance of growth in height than those from the south of the country. At the provenances studied, was observed the instability of the phenotypic variability, which resulted in the change of ranking regarding their growth in different years. This fact suggests that the genetic expression of growth in height occurs gradually, stadially, in the ontogenetic process of tree development. Also, is evident a strong hereditary infl uence of the oaks of origin on the growth rate of the descendants. The use of acorns within the limits of a forest body is risky with the reduction of the genetic diversity of the natural population. Under the conditions of climate change, the transfer of reproductive forest materials within the limits of the Central Moldavian Plateau can be admitted because the pedunculate oak has a vast genetic variability in terms of traits important for adaptation. The assisted migration within the limits of the center area to the oak, a species with a long life cycle and vast genetic variability, is justifi ed by the fact that natural selection will speed up the adaptation process of trees with the prediction of climate changes.","PeriodicalId":39216,"journal":{"name":"Thaiszia Journal of Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81928176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The annual application of compost in a natural meadow of a transitional type with Chrysopogon gryllus–Agrostis capillaris, increased significantly (P <0.001) the amount of dry matter in the treated variants from 57.77% (at a fertilizer rate of 3000 kg/dka) to 73.79% (at a fertilizer rate of 2000 kg/dka) compared to the untreated control. Grass stands fertilizerd at a rate of 2000 kg/dka increased to the highest degree the presence of legume components (from 44.7% to 71.2%) in the biomass, which is a prerequisite for the production of fodder with a high crude protein content. The compost application had a positive impact on the grass mass composition and contributed to positive changes in the group of desirable legume and grass meadow species. An increased share of useful legume (Trifolium pratense, T. hybridium, T. agrarium and Lotus corniculatus) and grass meadow species (Agrostis capillaris, Festuca rubra, Cynosurus cristatus and Poa pratensis) and stimulation of their productive potential was found. In the fertilized variants, the percentage share of weeds participate followed a downward trend compared to the control. Fertilizing with compost of bracken and manure is a highly effective measure and can be recommended to increase hay yields in natural grass stand (а transitional type with Chrysopogon gryllus-Agrostis capillaris) in the conditions of the Central Balkan Mountain.

By way of field surveys and herbarium research, 121 alien taxa (22.1% of the regional flora) were recorded. The most species rich families are Poaceae (24 taxa, 19.8%) and Asteraceae (22, 18.2%). Species richness is about evenly distributed across genera with Rumex, Artemisia and Poa (each contains 3 taxa or 2.5%) making up those with the greatest number of species. Concerning plant growth habits, the two dominant groups are forbs (94 taxa, 77.7%) and graminoids (23 taxa, 19%). Regarding habitat preferences, most alien plants occur in natural and seminatural habitats (48 taxa, 39.7%), ruderal places (43 taxa, 35.5%) and agricultural lands (30 taxa, 24.8%). In relation to the state of spread, invasive (63 taxa, 52%) and naturalised (48 taxa, 39.7%) species prevail. In terms of geographical origin, most alien plants are native to Eurasia–Africa (49 taxa, 40.5%) and Eurasia (34 taxa, 28.1%). The biosphere reserve is increasingly being invaded by alien plants whose introduction and distributions can be explained by intense agricultural pressure which resulted in extensive habitat alteration and proliferation of invasive species.
