    Plant Diversity and Ecological Indices of Naturally Established Native Vegetation in Permanent Grassy Strips of Fruit Orchards in Southern Romania

    by Sina Cosmulescu, Florin Daniel Stamin, Daniel Răduțoiu, Nicolae Constantin Gheorghiu

    This paper assesses the complexity and diversity of vegetation in grassy strips with spontaneous plants between tree rows in three fruit orchards (plum, cherry, apple) in Dolj County, Romania, using structural and biodiversity indices. It addresses the lack of data on spontaneous vegetation in Romanian orchards, supporting improved plantation management and native biodiversity conservation. The study found that grassy strips supported high wild herbaceous diversity and a complex, heterogeneous ecological structure, with the apple orchard showing the highest biodiversity. Species diversity, evaluated through species richness, evenness, and diversity indices (Shannon, Simpson, Menhinick, Gleason, etc.), showed species richness ranging from 30 species in the cherry orchard to 40 in the apple orchard. Several species, including Capsella bursa-pastoris, Geranium pusillum, Poa pratensis, Veronica hederifolia, Lolium perenne, and Convolvulus arvensis, were present in 100% of samples, making them constant species from a phytosociological perspective. Their presence indicates relatively stable plant communities in each orchard. From a phytocoenological view, an ecological plant community is defined not only by species composition but also by constancy and co-occurrence in sampling units. Dominance remained low in all orchards, indicating no single plant dominated, while evenness showed a uniform distribution of species.

    ASPECTS REGARDING VARIETY/ROOTSTOCK RELATIONSHIP IN SOME SPECIES OF FRUIT SPECIES

    by Mihai Cichi, Nicolae Gheorghiu

    Obtaining large and quality productions requires, in addition to agrotechnical measures, the establishment of the most appropriate symbiosis between grafts (varieties) and rootstocks. This variety/rootstock union particularly influences tree growth, production and quality. Knowing the growth of the root system has an important role in choosing the system of use and tillage, in choosing the land.   The varieties of nectarine on the frank peach rootstock had different vigor, vigor represented by the height, the diameter of the crown, respectively a lower vigor was recorded in the Marina variety, the other varieties being noted with much greater vigor. Compatibility between nectarine varieties and rootstocks was very good, with no split at the grafting point. Deeply developed roots were found in Costin, Tina and Romamer 2 nectarine varieties. Varieties from the pear species namely Williams red, Clapp's Favorite and Daciana showed average vigor and very good rooting - the same varieties together with the Williams white variety.
