Abstract

Economic potential and growing public interest in the grapes have led to the plant having high prospects for cultivation and development in other parts of Indonesia. The aim of this research is to produce quality seedlings through network culture techniques. The method of providing grape seed is relatively fast with the amount of seed produced quite a lot that is through the technique of network culture. The research was conducted from March to May 2023 at the Laboratory of Physiology and Culture of Plant Networks, Faculty of Mathematics and Natural Sciences, University of North Sumatra, Field, North Sumatera. Parameters observed in Vitis vinifera plant tissue culture practices with a combination of IAA and BAP treatment on MS media are growth time, growth percentage and contamination percentages. Data from the study was analyzed using Analysis Of Variance (ANNOVA). If the treatment gives a significant different effect then proceed with the Duncan New Multiple Range Test (DNMRT) at the level of 5% (P 0.05) on the treatment factor.Treatment I1 has the fastest increasing power output with an average growth time of 9 a. Further testing results show that the treatment of IAA and BAP hormones in different media is significantly higher than the control. The results of the study showed that the highest percentage of explanation growth (100%), although it took a relatively longer time to form the calus and shoots.

Abstract

A variety of plants are found in the Medan State University (Unimed) campus area which is in the border area of Medan city, precisely in Deli Serdang Regency with an area of ± 495,000 m2. Flowering plants (Angiosperms) are one of the groups of plants that make up the vegetation on the Unimed campus with various types, characteristics (habitus) and various benefits. These flowering plants not only have aesthetic and ecological value but can also be a learning resources. However, there is no data yet on what types of flowering plants (Angiosperms) are found in the campus area. An inventory carried out in the Unimed campus area obtained 80 species of flowering plants belonging to 71 genera and 33 families. The diversity of flowering plants is dominated by the Arecaceae family with 7 species from the monocot group and 13 species from the Fabaceae family which are included in the Dicot group. The various forms of appearance (habitus) of these flowering plants are herbs, bushes, shrubs and trees and their various uses include ornamental plants, shade plants, fruit-bearing plants and medicinal plants.

Abstract

 Muara Ampolu Village located in Batangtoru District, Deli Serdang Regency is a terrestrial ecosystem with hill topography which is generally used as a production forest for oil palm cultivation and generally has natural forest vegetation. The increasing opening of oil palm commodity production is in line with land clearing in the study area and is expected to affect the condition of the surrounding environmental components, especially terrestrial flora. Inventory was conducted to determine the diversity of terrestrial flora species found in the study area and to minimize the rate of loss of terrestrial flora species diversity in the area. Terrestrial flora found in the study area includes 41 species belonging to 31 families in residential and agricultural areas; while in the hill forest area, 285 species belonging to 43 families were obtained. Terrestrial flora in settlements are plants deliberately planted and/or left by residents because they have benefits as food, aesthetics, shade, herbal medicine, and as ground cover and other functions, while terrestrial flora in hill forests is dominated by pioneer plants such as Mallotus spp. and Macaranga spp. and the presence of Ficus padana species; climax forest vegetation such as Castanopsis spp., and from the Dipterocarpaceae family namely Dryobalanops spp., Shorea spp., Dipterocarpus spp.; and invasive species such as ilalang (Imperata cylindrica) and sandukan (Melastoma malabatricum).
