Liwa Botanical Garden is located in West Lampung Regency which has an area of 86.6 hectares and is one of the conservation of ornamental plants that presents the flora of the Bukit Barisan Selatan National Park. One of the flagship collections of this botanical garden is a native orchid. Disease infection is still a major obstacle in the cultivation and development of native orchid potential at Liwa Botanical Garden. Based on the results of previous studies, it is known that several individual natural orchid collections from Liwa Botanical Garden showed symptoms of fungal disease infections. Disease infections can inhibit plant growth and resistance and reduce the aesthetic value periodically. Symptoms of infection include necrotic patches on the upper surface of the leaf. This research was conducted to determine the identification of diseases and efforts to protect native orchids against fungal infections at Liwa Botanical Garden through a collection of samples that showed symptoms of infection, analysis of disease symptoms, and analysis of disease resistance levels. The results showed that the response of the native orchid at Liwa Botanical Garden to fungal infections was showed symptoms of wilting in the leaves, namely in the orchids Eria sp., Dendrobium sp., and Cymbidium sp. turns black on the edge of the leaf, Thrixspermum sp. The type of orchid most commonly infected with fungus is Cymbidium sp. a total of 8 samples, and Thrixspermum sp. 3 samples, Eria sp. as many as 4 samples, Dendrobium sp. and Calanthe triplicata as many as 6 samples. The type of native orchid that is most susceptible to fungal infections is Dendrobium sp. and Eria sp. with disease intensity of 74.11% and 22.3%. The results of this activity are expected to be basic information in efforts to protect plants against diseases to support the application of conservation of native orchids on Liwa Botanical Garden.

Abstract Manipulation of plant growth via pruning and training methods has been carried out for as long as crops have been cultivated by man. These methods serve to not only improve the aesthetic value of ornamental plants, but also to increase yields, optimise fruit quality and prolong the productive life of horticultural crops. Pruning involves the selective removal of a diverse range of plant tissue. Branches, stems, roots, buds, flowers, leaves and young fruitlets may all be pruned depending on the purpose, species and growth form of the crop this is applied to. Training methods for horticultural applications are primarily used to support the plant and the weight of produce as it develops. Training structurally alters plant form, to alter the shape, size and direction of plant growth, it also allows optimal light interception and air flow and for ease of access for harvesting and other operations.

Variations in flowering time and plant architecture have a crucial impact on crop biomass and yield, as well as the aesthetic value of ornamental plants. Aechmea fasciata, a member of the Bromeliaceae family, is a bromeliad variety that is commonly cultivated worldwide. Here, we report the characterization of AfSPL14, a squamosa promoter binding protein-like gene in A. fasciata. AfSPL14 was predominantly expressed in the young vegetative organs of adult plants. The expression of AfSPL14 could be upregulated within 1 h by exogenous ethephon treatment. The constitutive expression of AfSPL14 in Arabidopsis thaliana caused early flowering and variations in plant architecture, including smaller rosette leaves and thicker and increased numbers of main inflorescences. Our findings suggest that AfSPL14 may help facilitate the molecular breeding of A. fasciata, other ornamental and edible bromeliads (e.g., pineapple), and even cereal crops.

<p>Aesthetics is a pillar consideration in historic preservation. Yet, purposing aesthetics for historic preservation ends seems to lag behind the opportunities. Utterly subjective, aesthetics poses challenges for the preservation community worldwide to moderate, accommodate, and purpose aesthetics in heritage programs. The challenges revolve around the assessment of aesthetical purposing in three domains. These domains include the community disposition towards accommodating aesthetics (advocacy), the criteria and strategies for assessing the aesthetic value of historic resources (signification), and, the standards for treating historic resources in preservation projects (interpretation). This study, therefore, assesses the trends for purposing aesthetics in historic preservation thought and practice through three platforms: advocating aesthetics, signifying aesthetics, and interpreting aesthetics. The study completed literature content analysis on aesthetics in general and aesthetics in historic preservation in particular. Further, because of the perspective of the study, the works of international and country preservation programs provided information relevant to advocacy, signification, and interpretation of aesthetics that have been refined by classification, comparison, and exemplification methods. Among others, these works include those of the International Council on Monuments and Sites (ICOMOS) and the U.S. National Historic Preservation Program in the National Park Service. The study culminated with general and platform-specific conclusions. First, as the three proposed platforms (advocacy, signification, and interpretation) maintain structural and serial relationships, they constitute a relevant and feasible framework for assessing aesthetical purposing. Second, as the aesthetical purposing assessment followed a broad, international perspective, the conclusions of the study are commensurate with the selective scope of information used from international and country preservation programs. Third, the contribution to aesthetical purposing at each of the three platforms can be measure only in general, and at times, subjective terms.</p><p><strong>Highlights:</strong></p><ul><li><p>Proposing aesthetical advocacy, aesthetical signification, and aesthetical interpretation as a platform framework to assess the purposing of aesthetics was feasible.</p></li><li><p>As aesthetical purposing was approached from a broad, international perspective, the conclusions of the study commensurate with the selective scope of information used.</p></li><li><p>The contribution to aesthetical purposing at each of the three platforms is hard to measure; however, the indications point to uneven contribution.</p></li></ul>

Diagnosis of incipient disease based on visual symptoms of geraniums (Pelargonium ×hortorum) exposed to water mold pathogens is often difficult, especially when the plants are maintained under optimum growing conditions. Such plants tend to be asymptomatic until late in the infection process when control methods are less effective and the aesthetic value of the finished crop is diminished. To circumvent such a problem and to be able to predict the susceptibility of the plants to infection, we used infrared transducers to measure leaf surface temperature, in addition to other parameters, in geranium plants exposed to a number of soil pathogens that are commonly associated with greenhouse production. Differences in leaf temperature among treatments were noticeable by 2 week after inoculation and were the greatest in week 7. However, visual disease symptoms were not detected until 3 weeks after inoculation. Results of this study suggest that leaf temperature measurements are a versatile, nondestructive way of rapidly determining whether plants are under pathogen stress before visual symptoms develop.

Utah Juniper

Utah junipers (Juniperus osterosperma (forr.)) are the dominant trees in the landscape of the southwestern states (35 million hectares). In Utah, the pinyon-juniper woodland represents 28.6% of the vegetation and are an important part of the aesthetic value of the Utah national parks. Over the past several years, extensive foliar damage has occurred to Utah juniper, yet little foliar damage has been observed in Natural Bridges National Monument, Canyonlands National Park, Arches National Park, Mesa Verde National Park and Colorado National Monument. The characteristic pattern is for the distal foliage to become chlorotic and die. Mortality progresses along twigs until whole branches or even the entire tree dies. The cause for the foliar damage is unknown. The loss of juniper trees in the national parks in southern Utah would have a dramatic ecological impact and would be an aesthetic blight in the parks. The purpose of this investigation is to determine the cause of the die-off of Utah junipers and suggest management options concerning the juniper die-off problem.

Ecological environment in urban areas is specific in many aspects. There are evidences that ornamental plants cultivated in local urban gardens may help in conservation of pollinators. In this study, the flowering pattern, the abundance of flowering, nectar and pollen production as well as insect visitation in <em>Arabis procurrens</em> Waldst. &amp; Kit. and <em>Iberis sempervirens</em> L. were investigated. The species were grown in the UMCS Botanical Garden in Lublin, southeastern Poland. <em>Arabis procurrens</em> bloomed from the middle of April until middle of May and <em>I. sempervirens</em> from the end of April until middle of June. In both species, most flowers opened in the morning hours (40–45% of total were opened by 8:00 h GMT + 2 h). The average sugar yield of <em>A. procurrens</em> was ca. 53% lower compared to <em>I. sempervirens</em> (mean = 1.08 g/m<sup>2</sup> and 2.32 g/m<sup>2</sup>, respectively). In both species, considerable differences in the amount of produced sugars were noted between years. The mass of pollen produced in the flowers of <em>A. procurrens</em> was approx. 35% lower compared to that of <em>I. sempervirens</em> (mean = 0.06 mg and 0.09 mg per flower, respectively). Pollen produced per unit area was correlated with the number of flowers. On average, the species produced 1.46 g (<em>A. procurrens</em>) and 2.54 g (<em>I. sempervirens</em>) of pollen per 1 m<sup>2</sup>. The flowers of <em>A. procurrens</em> attracted mainly dipterans (56.3% of total visitors), while <em>I. sempervirens</em> lured chiefly solitary bees (47.4% of total visitors), however in both cases, honeybees, bumblebees and lepidopterans were also recorded. The <em>A. procurrens</em> and <em>I. sempervirens</em> due to flowering in early spring period may be promoted for use in small gardens (rock or pot gardens) for both aesthetic value and as plants that support insect visitors in nectar and pollen rewards.
