ABSTRACT Fungi responsible of rot diseases reduce crops yields and contaminate the harvestable food products with mycotoxins noxious for human and animal health. They include the Fusarium species causing cereal rots, which are fumonisin and trichothecene producers, and Aspergillus species of the Nigri section responsible of black grape rots and ochratoxin A (OTA) production. Chemical control of these fungi is based in the use of commercial fungicides which are expensive, generate environmental pollution and led to the development of fungal resistance. Plant extracts might provide new antifungals overcoming these problems. In this work, the inhibitory effect of extracts from aerial parts (leaves and stems) of native plants from northwest Argentina (Amphilophium cynanchoides, Tecoma stans, Macfadyena cynanchoides and Jacaranda mimosifolia) was investigated on Fusarium (F. graminearum and F. verticillioides) and Aspergillus (A. carbonarius and A. niger) species. Ten of a total of 24 extracts inhibited 50% of the fungal growth (IC50). Microdilution assays indicated that the extracts with the lowest IC50 values were the ethyl acetate leaf and stem extracts of A. cynanchoides against F. graminearum (IC50=1320 ppm) and F. verticillioides (IC50=1305 ppm), respectively, and the dichloromethane stem extract of M. cynanchoides against A. niger (IC50=1025 ppm) and A. carbonarius (1066 ppm). The dichloromethane stem extract of M. cynanchoides was the only one that completely suppressed fungal growth (MIC) at 2500 ppm. It was antifungal on all the fungal strains in dot blot assays where Aspergillus strains were more sensitive than the Fusarium strains.

    2018 International Conference on Zoology, Botany and Ecology (ICZBE 2018) Study on the Relationship between Plant Distribution and Local Atmospheric Environment in Guangdong Province 1 1,* Minqing Huang , Desenke 1School of life science , Guangzhou University , Guangzhou 51006, China a Minqing Huang,[email protected], b Desenke,[email protected] *Corresponding author, Tel: 13342884383 Keywords: Vegetation, Air pollution, Phytoremediation. Abstract. Plants can rise to purify the atmosphere, the coverage rate of plants and the species of plants are the influencing factors of the atmospheric environment within a certain area. To explore the relationship of plant distribution and local atmospheric environment association between the Shaoguan and the Zhanjiang in Guangdong Province, we can see the vegetation coverage in Shaoguan area is higher than that in Zhanjiang area, but the plant species in Zhanjiang area is more targeted. In a word, the air quality of Zhanjiang area is higher than in the Shaoguan area. So strengthening the study of phytoremediation of air pollution is beneficial to the sustainable development of ecosystem. 1. Introduction Plants, which can exchange large amounts of gases with air through photosynthesis, are important members of the ecosystem. In addition, the surface of the plant will be deposited dry and wet by pollutants that exist in the atmosphere, while plant cells can dissolve gaseous substances and absorb soluble compounds deposited on the plant surface [1]. And different plants have different effects on their atmospheric environment [2] The zonal forest is a typical evergreen broadleaved forest in the subtropics in the north, a subtropical monsoon evergreen broad-leaved forest in the middle, and a tropical rain forest and a monsoon rainforest in the south in the geographical distribution of Guangdong forest.

A total of 141 species (including 14 ferns) were Motuora Island lies in the Hauraki Gulf southwest of recorded. Exotic plants confined to the gardens Kawau Island, approximately 3km from Mahurangi around the buildings at Home Bay were not included Heads, and 5km from Wenderholm Regional Park, in Dowding’s (1988) list. Dowding (1988) commented Waiwera. This 80ha island is long and narrow on four adventive species that were “well-established” (approximately 2km x c. 600m at its widest) with a and that “may present problems” (presumably for a relatively flat top, reaching 75m asl. The land rises future restoration project). These species were abruptly, in places precipitously, from the shoreline so boneseed (Chrysanthemoides monilifera), boxthorn that the area of the undulating ‘level’ top is (Lycium ferocissimum), gorse (Ulex europaeus) and comparatively extensive. Composed of sedimentary kikuyu grass (Pennisetum clandestinum). All four strata from the Pakiri formation of the Waitemata species still require ongoing control. However, as a Group (Lower Miocene age, approximately 20 million years old), Motuora is geologically similar to other result of ongoing weed eradication endeavours, inner Hauraki gulf islands such as Tiritiri Matangi, boxthorn has been reduced to a few isolated sites, Kawau, Waiheke and Motuihe Islands (Ballance 1977; and boneseed once widespread on the island is Edbrooke 2001). considerably reduced also, occurring in high densities now only on the northern end of the island (Lindsay History 2006). Gorse and kikuyu are controlled where these Motuora Island was farmed, from as early as 1853 species inhibit revegetation plantings.

  • Systematic Conservation Planning in Thailand
    SYSTEMATIC CONSERVATION PLANNING IN THAILAND DARAPORN CHAIRAT Thesis submitted in total fulfilment for the degree of Doctor of Philosophy BOURNEMOUTH UNIVERSITY 2015 This copy of the thesis has been supplied on condition that, anyone who consults it, is understood to recognize that its copyright rests with its author. Due acknowledgement must always be made of the use of any material contained in, or derived from, this thesis. i ii Systematic Conservation Planning in Thailand Daraporn Chairat Abstract Thailand supports a variety of tropical ecosystems and biodiversity. The country has approximately 12,050 species of plants, which account for 8% of estimated plant species found globally. However, the forest cover of Thailand is under threats: habitat degradation, illegal logging, shifting cultivation and human settlement are the main causes of the reduction in forest area. As a result, rates of biodiversity loss have been high for some decades. The most effective tool to conserve biodiversity is the designation of protected areas (PA). The effective and most scientifically robust approach for designing networks of reserve systems is systematic conservation planning, which is designed to identify conservation priorities on the basis of analysing spatial patterns in species distributions and associated threats. The designation of PAs of Thailand were initially based on expert consultations selecting the areas that are suitable for conserving forest resources, not systematically selected. Consequently, the PA management was based on individual management plans for each PA. The previous work has also identified that no previous attempt has been made to apply the principles and methods of systematic conservation planning. Additionally, tree species have been neglected in previous analyses of the coverage of PAs in Thailand.

Barua*, Girish Gogoi and Protul Hazarika Ecology and Biodiversity Division, Rain Forest Research Institute, Post Box No. 136, Sotai, Jorhat-785001, Assam, India *Corresponding Author: [email protected] [Accepted: 27 August 2018] Abstract: Knowledge of species composition and diversity are of utmost importance, not only to understand the structure of a forest community but also for planning and implementation of conservation strategy of the community. An extensive field study was undertaken to ascertain the structural composition, species diversity and community association of two forest sites i.e. Nambor Wildlife Sanctuary (NWLS) and its South-Westward extended Bornewria forest of Assam, India. The forests represent Tropical moist semi-evergreen and moist mixed deciduous type. The entire area was embraced with a fragmented block of Gondowana formation. A total of 261 plant species were observed from the two forests sites in floristic assessment. Out of which 247 species were recorded from NWLS and in Bornewria forest 136 were enumerated. The overexploitation and shifting cultivation adversely affected the total forested area and species composition of Bornewria forest. Phytosociological studies showed that Vatica lanceaefolia (15.47) followed by Magnolia hodgsonii (10.97), Castanopsis hystrix (10.02) and Mesua ferrea (9.56) were dominated in NWLS. However, in case of Bornewria forest, Hydnocarpus kurzii expressed its dominance with highest IVI values (15.98), followed by Dysoxylum excelsum (13.52), Mesua ferrea (12.37) and Stereospermum tetragonum (11.87).

  • Non-Invasive Monitoring System Based on Standing Wave
    Yang et al. Plant Methods (2021) 17:56 https://doi.org/10.1186/s13007-021-00757-y Plant Methods METHODOLOGY Open Access Methodology: non-invasive monitoring system based on standing wave ratio for detecting water content variations in plants Yunjeong Yang1†, Ji Eun Kim1†, Hak Jin Song1†, Eun Bin Lee1, Yong‑Keun Choi1, Jeong Wook Jo1, Hyeon Jin Jeon1, Ho Hyun Kim2, Kwang Jin Kim3 and Hyung Joo Kim1* Abstract Background: Water content variation during plant growth is one of the most important monitoring parameters in plant studies. Conventional parameters (such as dry weight) are unreliable; thus, the development of rapid, accurate methods that will allow the monitoring of water content variation in live plants is necessary. In this study, we aimed to develop a non‑invasive, radiofrequency‑based monitoring system to rapidly and accurately detect water content variation in live plants. The changes in standing wave ratio (SWR) caused by the presence of stem water and magnetic particles in the stem water fow were used as the basis of plant monitoring systems. Results: The SWR of a coil probe was used to develop a non‑invasive monitoring system to detect water con‑ tent variation in live plants. When water was added to the live experimental plants with or without illumination under drought conditions, noticeable SWR changes at various frequencies were observed. When a fxed frequency (1.611 GHz) was applied to a single experimental plant (Radermachera sinica), a more comprehensive monitoring, such as water content variation within the plant and the efect of illumination on water content, was achieved.
