Banana Flower-Insect Interaction: Alpha-Pinene as Potential Attractant for the Insect Vector of Banana Blood Disease

Masriany Masriany, Rizkita R Esyanti, Fenny M Dwivany, Tjandra Anggraeni
Volatile metabolites are produced by plants for self-defense and as communication mediators with the environment. Terpenes are volatiles emitted as odorant cues for herbivores and microorganisms. This study was aimed to investigate volatile metabolites produced by banana flowers that attract insect vectors of BBD. The volatile metabolites from banana flowers were extracted by headspace-solid phase microextraction (HS-SPME) and identified by gas chromatography–mass spectrometry (GC-MS). It was ap...

ANTIOXIDANT PROPERTIES OF PISONIA ALBA PLANT LEAF EXTRACT

Tamizhazhagan, Pugazhendy, Sakthidasan, and Jayanthi, C2.
The methonolic extract of the leaves of Pisonia alba (PA) were subjected to phytochemical analysis by standard qualitative analysis and the invitro antioxidant activity was evaluated by determination of total antioxidant capacity, 1.1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, Antioxidant activity, Nitric oxide potential. The analyses revealed that the methanol extract of Co was able to efficiently scavenge the free radicals in a dose dependant manner. The results were compare...

THE POTENTIAL UTILIZATION OF AROMATIC PLANTS IN KEMBANG KUNING RESORT, GUNUNG RINJANI NATIONAL PARK, WEST NUSA TENGGARA

Vina Savinatus Sa'adah, Ervizal A. M. Zuhud, Siswoyo
Gunung Rinjani National Park (TNGR) is nature conservation area located in West Nusa Tenggara. Kembang Kuning Resort is one of the TNGR‘s resorts under Territory Management Section (SPW) II East Lombok which has high potential for biological diversity which one of them is aromatic plants. Aromatic plants are plants that produce essential oils. dentify the diversity of aromatic plant species, and ethnobotany aromatic plants in communities around the area. The methods used are the vegetation analy...

SPONTANEOUS POPULATIONS OF TAXUS TYPES (TAXACEAE) IN SYRETS ARBORETUM

Оleksandr Shynder, Оleksandr Rak, Svitlana Hlukhova
The article presents the data on the status and structure of the spontaneous heterogeneous population of two species of the genus Taxus (Taxaceae), T. baccata and T. cuspidata, in the Syrets Arboretum of national importance (Kyiv). This population was formed as a result of spontaneous seed reproduction of cultured in the arboretum of adult specimens of two species of yew. The author describes the quantitative composition of individuals of the genus Taxus of seed origin and the conditions of thei...

DISTRIBUTION OF POLYSTICHUM ACULEATUM ON THE SLOVECHANSKO- OVRUCHSKYI RIDGE

?van Khomiak, Iryna Onyschuk
During expedition on the Slovechansko-Ovruchskyi ridge in 2016–2018, we discovered new location of regionally rare species Polystichum aculeatum. This fern usually belongs to the mountain flora. New findings of plant species require additional research of its coenotic and ecological characteristics. We have found that the population of plants is a stenotope for most environmental factors. The zone of tolerance for this species is wider than we previously thought. This increases competitive capab...

SOIL AND FOREST BEDDING СО2 EMISSION IN DIFFERENT TYPES OF FOREST PHYTOCENOSIS

Iryna Vyshenska, Maryna Rudko
The article presents the results of the study of carbon dioxide emission of forest litter and soil in two forest phytocoenoses of different types (coniferous pine and broadleaf oak forests). The study is aimed to measure and compare soil respiration and carbon dioxide emission from forest litter in broadleaf and conifer forests to assess the role of different forest phytocoenoses in the deposition of CO2 as an important greenhouse gas. The study of carbon dioxide emissions is conducted on two mo...

Recent pharmacological investigations of bryophytes have proven that the active principles present in these plants are quite unique and having potential chemical application and antioxidant capacity. In this study, the volatile components in extracts from Thuidium tamariscinum (Hedw.) Schimp. and Platyhypnidium riparioides (Hedw.) Dixon, Kazda?lar? (Kalkim-Yenice, ?anakkale, Turkey) were isolated by solid phase micro extraction technique and identified by mass selective detector gas chromatogra...

Changes in Biochemical Activity of Podzolic Chernozem under the Influence of Buckwheat Cultivation in the Conditions of Traditional and Organic Farming Systems

Ganna Tsygichko
The research identified changes in biological activity of Ukrainian forest-steppe chernozem podzolized under the growing of buckwheat both as the main crops and as the crops of predecessor indicators for enzyme activity and processes of ammonification and nitrification abilities in different farming systems. It was established that the use of buckwheat for the organic system contributed to the increasing of enzymatic activity and ammonification and nitrification abilities of chernozem podzolized...

Phytotoxicity of the Substrate of Coal Mine Dumps under the Influence of Thermal Power Plant ash and Potassium Humate

Yaroslav Shpak, Iryna Zapisotska, Volodymyr Baranov, Olha Terek
The influence of ash from the Dobrotvir thermal power plant dumps and potassium humate "STB-45" on the phytotoxicity of the rock dumps substrate of coal mines in Chervonograd mining region has been researched. Sudan grass Sorghum bicolor subsp. drummondii (Nees ex Steud.) has been used as a biotester. The increase of the stem height, leaf area, length and mass of roots under the influence of the addition of ash dumps to the substrate has been discovered. Application of the humate only has increa...
