Urbanization and fragmentation are the main factors causing dynamics in the pekarangan. The dynamics that occur are related to the structure and function of the pekarangan. This makes the pekarangan performance changes according to the interference of the pekarangan owner. Selahuni 2 Homlet, Ciomas Rahayu Village, Bogor has become the location for observing the dynamics of the past two decades. Pekarangan samples taken in 2019 are exactly the same as those taken in 1998 and 2007, totaling 10 houses. The aim is to determine the extent of changes that occur in the pekarangan, both structure and function. Measuring the area, ownership of the pekarangan, recording of species and function of the existing vegetation of the pekarangan. In 2019, data on ownership of houses and pekarangans by old owners dropped dramatically by only 40%. In 2019, the average pekarangan area will decrease by an average area of 110.81 m2. In 1998, 2007 and 2019, the percentage of the number of non-ornamental plant species was 4-10% higher than that of ornamental plants. Therefore, there was a change in both the extent and ownership, function and structure of the vegetation in the Selahuni 2 Homlet’s pekarangan which was caused by urbanization and fragmentation factors.

Sixty stands of Scirpus acutus Muhl. and S. validus Vahl from five areas in southern Manitoba were examined to determine (i) whether the two were morphologically distinguishable within the region studied and, if so, (ii) which morphological characters were the most useful to separate them. Thirteen characters were measured on pressed and living specimens. From these, six bimodally distributed characters were objectively selected to calculate a biometric index for each specimen. Mean indices for 56 stands were separable into two groups, indicating that they contained pure populations of one taxon. Three stands had mixed populations, and one contained morphologically intermediate individuals. The two taxa can be consistently identified using a combination of six characters. Scirpus acutus has an inflorescence < 47 mm long, less than seven primary rays, no secondary rays, clusters of more than five spikelets, aerenchymal lacunae < 0.9 mm in diameter, and dark green culms in fresh specimens. In contrast, S. validus has inflorescences > 80 mm long, more than 13 primary rays, secondary, tertiary, and occasionally quaternary rays present, spikelets generally in clusters of one to three, aerenchymal lacunae > 1.5 mm in diameter, and light green culms in fresh specimens. Data from Manitoba populations support their status as separate species.

Humanity has used plants for aesthetic purposes for centuries. Plants nowadays use cities for more livable habitats and similar purposes to satisfy the longing for nature of people who move away from nature due to increasing urbanization. So that plants attract attention as a commercial field plays a crucial role in economic development for many countries today. Our country, which is one of the richest geographies in terms of biodiversity globally, shows a total of 11466 plant taxa, 3800 of which are endemic. While the total number of plant species in all of Europe is around 12.000, in our country there are approximately 10.000 species. When the species and subspecies identified in recent years are added, around 12,000 taxa find natural habitats in our country. Mersin province is one of the important endemism centers of our country, with approximately 400 endemic species (endemism rate is approximately 23%). It is seen that the areas where geophytes spread intensively in the world are regions where the Mediterranean climate prevails, which is humid and warm in winters and dry and hot in summers. The Mediterranean Basin, where our country is located, is the second richest geophyte region in the world. Mersin province is one of the provinces located in the Mediterranean Basin. Within the scope of this study, it is to determine the usability of endemic plant species that are naturally distributed in Mersin province as ornamental plants and to ensure that they gain economic value in the ornamental plant market. For this purpose, in our study, some monocotyledon taxa that have an ornamental plant potential from endemic plant taxa in Mersin have been determined, and photographs of these taxa are presented. The recommended taxa are geophyte taxa, and the fact that they only spread in our country (some only in Mersin) is of great importance in bringing these species into the landscape as ornamental plants. A total of 20 endemic taxa belonging to 5 different monocotyledon families identified in Mersin were determined. The endangered extinction of some of these taxa proposed as ornamental plants is also of great importance in ensuring their generation by bringing them into the landscape with various production techniques.

Columnea latent viroid, originating from ornamental plants, is known to be harmful to crop plants (2). Despite the potential threat to crop plants, the importance of ornamental plants in viroid evolution is not fully appreciated. Availability of a Pospiviroid genus-specific primer pair (1) to detect the most prevalent viroids in ornamental plants and a simplified nucleic acid preparation protocol (3) for use in reverse-transcription polymerase chain reaction (RT-PCR) have facilitated surveys of ornamental plants for pospiviroids. Using the above protocol in India, leaf and shoot samples were collected randomly from roadside beds consisting of ground covers or creepers/trailing plants at the IARI campus, New Delhi. These were extracted in 50 mM NaOH + 2.5 mM EDTA solution, centrifuged to sediment the coarse debris from sap, and 10 μl of the supernatant was spotted on a nitrocellulose membrane. Individual spots were eluted with distilled sterile water (30 μl) and the eluates were used for RT-PCR detection of viroids (3). Amplified fragments or subsequently cloned plasmids were also purified using NaOH-EDTA membrane protocol. Cloning and sequencing of amplicons (195 to 224 bp) revealed a very high sequence identity with specific viroids from the viroid sequence database (NCBI). Among the 19 plant samples assayed, only three plant species were infected by viroids, although none of them exhibited any symptoms. The three plant species included: (i) moss verbena, Glandularia puchella (Verbenaceae, native to Argentina and Chile, now established in several regions of the world), infected with a viroid (Accession No. DQ846884) having 99% sequence identity to Citrus exocortis viroid (CEVd) (Accession No. S67446); (ii) trailing verbena, Verbena × hybrida (Verbenaceae, ornamental plant), doubly infected with a viroid (Accession No. DQ846885) having 95% sequence identity to CEVd (Accession No. DQ094297) and infected with another viroid (Accession No. DQ846883) having 98% sequence identity to Tomato chlorotic dwarf viroid (TCDVd) (Accession No. AF162131); and (iii) red joyweed, Alternanthera sessilis (Amaranthaceae, a perennial weed herb) infected with a viroid (Accession No. DQ846886) having 96% sequence identity to Iresine viroid (IrVd) (Accession No. DQ094293). CEVd and TCDVd were mechanically transferred to tomato seedlings causing reduced growth of plants, smaller leaves, and bunchy-top appearance of plants, symptoms similar to those typically observed with other isolates of these viroids. As expected from previous studies, IrVd was not transmitted to tomato plants. Natural infection of verbena with CEVd has been detected in North America (2) but this was a novel observation in India. Additional novel observations include: A. sessilis as a new host for IrVd; and TCDVd is the first crop viroid to be isolated from a naturally infected ornamental plant. The significance of these viroid findings in ground cover and widely grown ornamental plants may lie in their potential role in spreading the viroids to citrus plants in citrus-growing countries such as India.

Silicon is known as an element stimulating plant immunity and resistance to unfavorable conditions. Additional treatment with silicon may also cause a positive change in plant performance, improving the quality of ornamental plants. In the years 2009-2010, a two-factorial experiment was conducted involving three cultivars of seasonal ornamental plant species: creeping zinnia <i>Sanvitalia speciosa</i> 'Sunbini', vervain <i>Verbena</i> 'Patio Blue', and purslane <i>Portulaca umbraticola</i> 'Duna Red'. The first experimental factor was the concentration of Actisil preparation being an equivalent of 60, 120, and 180 mg Si×dm<sup>-3</sup>, applied three times by spraying, the second one was the type of medium: peat substrate and peat substrate with sand. The experiment proved the beneficial effect of fertilization with silicon on plant development of <i>Verbena</i> and the number of shoots of all examined plant species. The higher concentrations of Actisil were applied, the higher number of shoots the plants developed. Plants treated with Actisil also produced a higher number of buds and flowers or inflorescences featuring an increased diameter. Plants cultivated in peat substrate flowered better.
