This is Volume 1 - Issue 2 of the Journal of Research in Plant Sciences.
Plant Science or more appropriately referred to as Botanical science, is the branch of biological science that involves study of the morphology, anatomy, taxonomy and physiology of plants. It also includes study and analysis of molecular aspects of plant metabolic pathways, and the ecological relationships existing between various plants. In addition, plant sciences also include the study of basic concepts and applied aspects of experimental plant biology, genomics, , plant biochemistry, cell biology, evolutionary biology, functional plant breeding and systems biology.

La pudrición seca de los tubérculos de ñame es la enfermedad que en la actualidad ocasiona las mayores pérdidas económicas a los pequeños productores asociados a este cultivo en el Caribe colombiano, pues deteriora los tejidos internos del tubérculo, ocasionando la pérdida de su valor comercial y de la semilla. Actualmente, no se tiene certeza de la identidad de los agentes causales, por lo que la presente investigación se llevó a cabo con el objeto de colectar, aislar y caracterizar los hongos asociados a la pudrición seca de tubérculos de ñame cv. “Espino” en la región Caribe de Colombia en almacenamiento. El estudio se desarrolló entre los meses de febrero a octubre del año 2019, identificando las zonas productoras de ñame en la región Caribe colombiana y colectando en los municipios y veredas, tubérculos en almacenamiento. En el laboratorio se aislaron de las lesiones los hongos asociados y se identificaron a través de la amplificación de la región ITS (Internal Transcribed Spacer) del DNA ribosomal, complementado con los genes Calmodulina y β-tubulina 2. En total se aislaron 56 hongos asociados a las lesiones, los cuales fueron agrupados en 10 morfotipos, logrando la clasificación por género y especie de los mismos. De acuerdo con la caracterización realizada se puede definir que las especies DH2-Lasiodiplodia theobromae, DH3- Fusarium solani y DH6-Neocosmospora rubicola, se constituyen como los principales agentes causales de la enfermedad de la pudrición seca de tubérculos de ñame espino en almacenamiento en la región Caribe de Colombia.

Goal. To determine potato’s quarantine pests causative agents of potato wart and nematodes with determining degree of soil’s infectious load by disease causative agents.
Methods. Materials for researches were soils’ samples from different disease sources. The soil’s samples selection from one soil’s probe was conducted as per standard method ДСТУ (DSTU) 3355-96. Points of soil’s samples was fixed by GPS — navigator Garmin eTrex Legend. The potato wart causative agent determination and cysts of yellow potato cyst nematodes was conducted by flotation method in device «RUTA» in sodium iodide solution. The zoosporangia viability determining conducted with solution Coomassi blue G-250 usage.
Results of conducted researches for determining potato pests causative agents with potato wart pathogens in Carpathian region of Ukraine in 2019—2020 presented. The study showed different disease level of soil’s infecting by zoosporangia and potato cysts nematodes. The load was consisted of 56—68 zoosporangia/1 g of soil, 14—18 cysts of yellow potato cyst nematode, relatively. There were determined 42—48 zoosporangia/1g soil in Zakarpattia region, 40—45 zoosporangia in Ivano-Frankivsk region, 49 in Turka, Lviv region and 0 nematodes, relatively.
Conclusions. Apparatus «RUTA» is designed for potato quarantine pests determining. It is allowed to determine cysts of potato yellow cysts and causative agent of potato wart zoosporangia. The potato wart analysis and yellow potato cyst nematode infectious load Different infectious level of soil’s present disease infecting analysis showed.
