Effects of botanical gardens on student environmental perception

Hasan YILMAZ

This paper examines the role of the classroom environment in promoting student well-being and, more specif-ically, a sense of responsibility towards nature in the city. The study analyzed how indoor vs outdoor educational environments affect students' perception of events and phenomena focusing on emotional, behavioral and cognitive processes. It was conducted in the Kayakyolu Secondary School, Erzurum, Turkey with 282 students ranging in age from 11 to 14 in grades 5-8. They participated in reading a story in two distinct environments: an enclosed indoor classroom and an outdoor botanical gar ...Более

A new host for Fusarium algeriense causing crown and root rot on barley in Kyrgyzstan

Sezim COLDOŞBEKOVA | İsmail ERPER

After maize, wheat and rice, barley is the most widely planted and economically important cereal crop in the Kyrgyzstan's highlands (Usubaliev et al., 2013) and worldwide. In two barley fields in the Manas district of Bishkek, Kyrgyzstan, diseased plants exhibiting crown and root rot, stunting and brown discolouration on internodes were observed in 2020. Disease incidence was approximately 5 in the two fields.Small sections of root and crown tissues from diseased plants were surface sterilised in 1 (v/v) sodium hypochlorite solution for one minute before being placed onto potato dextrose agar ...Более

Trait profiling and genotype selection in oilseed rape using genotype by trait and genotype by yield*trait approaches

Hossein ZEİNALZADEH TABRİZİ

Selection and breeding for high-yielding in oilseed rape have always been one of the leading objectives for oilseed rape breeders. This process becomes more complicated when all quantitative traits are considered in selection in addition to grain yield. In the present study, 18 oilseed rape genotypes along with 2 check cultivars (RGS003 and Dalgan) were evaluated across 16 environments (a combination of 2 years and eight locations) in the tropical climate regions of Iran during 2018–2019 and 2019–2020 cropping seasons. The experiments were conducted in a format of randomized complete block des ...Более

Fungal Pathogens Associated with Crown and Root Rot in Wheat-Growing Areas of Northern Kyrgyzstan

İsmail ERPER | Şenol YILDIZ | Sezim COLDOŞBEKOVA | Tair Esenalı Uulu

Fungal species associated with crown and root rot diseases in wheat have been extensively studied in many parts of the world. However, no reports on the relative importance and distribution of pathogens associated with wheat crown and root rot in Kyrgyzstan have been published. Hence, fungal species associated with wheat crown/root rot were surveyed in three main wheat production regions in northern Kyrgyzstan. Fungal species were isolated on 1/5 strength potato-dextrose agar amended with streptomycin (0.1 g/L) and chloramphenicol (0.05 g/L). A total of 598 fungal isolates from symptomatic tis ...Более

Characterization of Pseudomonas syringae PV. syringae from diseased stone fruits in Kyrgyzstan and testing of biological agents against pathogen

Tinatin DOOLOTKELDİEVA | Saykal BOBUŞOVA

The plant diseases caused by the Pseudomonas syringae сomplex bacteria are economically important and occur worldwide on various plants, and it is as a pathogen that has not been the object of studies and little is known about its epidemiology in Kyrgyzstan. The conventional phenotypic (LOPAT, API tests) and PCR-assisted isolation were used for the identificationof Pseudomonas syringae pv. syringaе isolates from the affected organs of local stone fruits, such as peach (Prunus persica), cherry (Prunus subgen), apricot (Prunus armeniaca), and plum (Prunus salicina) samples taken from the Chy, Is ...Более

Characterization of cereal cyst nematodes in wheat using morphometrics, SCAR markers, RFLP, and rDNA-ITS sequence analyses

Şenol YILDIZ

In this study, morphological and molecular characterizations of twenty-four Heterodera populations (cereal cyst nematodes, CCNs) collected from wheat production fields in Turkey were carried out. Light microscopy, species-specific markers, RFLP, and ITS sequencing were used to identify the nematode populations. The obtained CCN populations were identified as Heterodera avenae, H. filipjevi, and H. latipons according to the morphometric analysis, which was confirmed by the molecular techniques. The ITS region sequencing analysis confirmed the species identification, and phylogenetic analysis of ...Более

The Effects of Arbuscular Mycorrhizal Fungi and Lead (Pb)Applications on Eggplant Seedling Growth and Nutrient Uptake

Mustafa PAKSOY | Önder TÜRKMEN

There are many factors, which negatively affect plant development. One of these factors is lead (Pb), which causes toxic effects on plants during the seedling period. Mycorrhizas (AMF) contribute positively to plant growth. In eggplant seedlings, it has been researched whether to tolerate the negative effects of lead with mycorrhizas. In the study, Gigaspora margarita (Gm) and Glomus intraradices (Gi) mycorrhizal races were applied before seeds were sown. After the first true leaves appeared, 5 different doses of Pb (0, 100, 200, 400 and 800 ppm) were given. As a result, the earliest true leaf ...Более

Construction, characteristics and high throughput molecular screening methodologies in some special breeding populations: a horticultural perspective

Hasan CAN | İbrahim İlker ÖZYİĞİT | Mustafa PAKSOY

Advanced marker technologies are widely used for evaluation of genetic diversity in cultivated crops, wild ancestors, landraces or any special plant genotypes. Developing agricultural cultivars requires the following steps: (i) determining desired characteristics to be improved, (ii) screening genetic resources to help find a superior cultivar, (iii) intercrossing selected individuals, (iv) generating genetically hybrid populations and screening them for agro-morphological or molecular traits, (v) evaluating the superior cultivar candidates, (vi) testing field performance at different location ...Более

Physiological, Morphological and Biochemical Responses of Exogenous Hydrogen Sulfide in Salt-Stressed Tomato Seedlings

Atilla DURSUN

Salinity causes yield and quality losses in agricultural production and therefore great economic losses around the world. Hydrogen sulfide (H2S) is known to play a crucial role to ease physiological and metabolic processes in plants, and also increases the tolerance of the plant against many abiotic stress conditions. In this study, we investigated the effects of H2S treatments (0, 25, 50, 75 and 100 mu M NaHS were applied as H2S donor) to the tomato seedlings to alleviate the harmful effects of salt stress (0, 75 and 150 mM NaCl). There was a significant decrease in plant growth and developme ...Более

Improving salt tolerance of bean (Phaseolus vulgaris L.) with hydrogen sulfide

Atilla DURSUN

The current study examined the H2S applications on growth, biochemical and physiological parameters of bean seedlings under saline conditions. The findings of the study indicated that salt stress decreased plant growth and development, photosynthetic activity, and mineral and hormone content [excluding abscisic acid (ABA)] in bean seedlings. Plant and root fresh mass and dry mass with H2S applications increased as compared to the control treatment at the same salinity level. Both salinity and H2S treatments significantly affected the net assimilation rate, stomatal conductance, transpiration r ...Более

Occurrence, identification and phylogenetic analyses of cereal cyst nematodes in Kyrgyzstan

Şenol YILDIZ | Tair Esenalı Uulu

The study investigated the status of cereal cyst nematodes (CCN) in the main wheat-growing areas of Kyrgyzstan in 2020. Soil samples were taken from 69 different wheat fields located in Chuy and Issyk-Kul provinces. CCN were found in thirty-one out of the sixty-nine locations surveyed. The highest occurrence of CCN was in the Tyup location in Issyk-Kul province with 81 cysts (250 cm3 soil)-1. The CCN populations were identified by both morphological and molecular analyses. According to the results, all populations were identified as Heterodera filipjevi. No variations in rDNA-ITS sequencing da ...Более

An app for apples: Citizen-led mapping of fire blight in Central Asia

Saykal BOBUŞOVA | Tinatin DOOLOTKELDİEVA

Fire blight, caused by the bacterial pathogen Erwinia amylovora, is a severe bacterial disease of apple and pear that can quickly destroy whole plants. In the last decade, it was also detected in Central Asia, where wild pomaceous fruit plants represent the dominant species in mid-altitude forests and constitute a critical foundation for the entire ecosystem. Efficiently informing farmers, forestry services and private persons about the instances and dangers of fire blight, the correct way to recognize the symptoms, and the methods of disease control is thus of paramount importance in a vast a ...Более
