Salt tolerance of endophytic root bacteria and their effects on seed germination and viability on tomato plants

Eren ÖZDEN

Salinity is one of the most brutal environmental factors limiting the productivity of agricultural lands worldwide. It is considered that the salinity may be one of the important reasons for the low yield in Igdir of the tomato plants, which is medium resistant (3-5 dS.m-1) among vegetables. Eco-friendly techniques such as endophytic root bacteria treatments (ERB) are needed to restore saline soils to agriculture and also to increase the yield of tomatoes. Endophytic bacteria colonizing the inside of plants increase plant growth by various mechanisms and also mitigate the adverse effects of bi ...More

Wheat gene pool of Kyrgyzstan

Mira CUNUSOVA

A botanical and ecological study of locally collected material showed that wheat landraces are represented in a very wide variety of ecological and morphological forms scattered in different areas of Kyrgyzstan. In total, 60 subspecies of spring wheat belonging to 6 species are found in Kyrgyzstan. There are several ecological groups on the territory of Kyrgyzstan. The most common ecotypes, rigidum and subrigidum, are related to Iranian-Asian subspecies. At present, about 80 varieties of the Kyrgyz wheat of Kazakh breeding and breeding of the CIS countries are successfully passing the state va ...More

Identification of Self-Incompatibility in Kyrgyzstan-Originated Apple Genotypes with Molecular Marker Technique

Abdıkerim ABDULLAYEV

Kyrgyzstan is among the mother lands of apple and thus quite rich in apple genetic resources. This study was conducted to determine S-allele profiles of apple genotypes collected from different regions of Kyrgyzstan. The apple materials used belonged to 4 different species (M. domestica, M. kirghisorum, M. sieversii, M. niedzwetzkyana) and a total of 137 genotypes were evaluated in the study. Scorable bands were obtained with the use of 11 primer combinations and band lengths varied between 210 /- 50 and 700 /- 50 bp. Present findings revealed the most common S-allele as S46. Present findings ...More

Potential of Turkish Beauveria bassiana isolates for the management of the polyphagous planthopper, Orosanga japonica Melichar 1898 (Hemiptera: Ricaniidae)

İsmail ERPER

Background Entomopathogenic fungi are a potential biological control agent for many pests. In this study, 14 native Beauveria bassiana isolates were molecularly identified and assessed for their virulence and mortality against adults of the polyphagous planthopper Orosanga japonica, Melichar (Hemiptera: Ricaniidae) a polyphagous sap-feeding insect, under laboratory conditions. Results Isolates obtained from naturally infected adults O. japonica were molecularly identified as B. bassiana by sequencing the internal transcribed spacer and 26S large subunit of ribosomal DNA. In the bioassay, the r ...More

DNA fingerprinting and assessment of some physiological changes in Al-induced Bryophyllum daigremontianum clones

İbrahim İlker ÖZYİĞİT

Aluminum (Al) is one of the most important stress factors that reduce plant productivity in acidic soils. Present work thereby analyzed Al-induced genomic alterations in Bryophyllum daigremontianum clones using RAPD and ISSR markers, and investigated responding changes in photosynthetic pigment (chlorophyll a, b, a/b, total chlorophyll and carotenoid) contents and total soluble protein amounts in plant leaves. The main reason for the use of bulbiferous spurs originated clone plants was to increase reliability and acceptability of RAPD and ISSR techniques in DNA fingerprinting. Raised 40 clone ...More

Tuta absoluta continues to disperse in Asia: damage, ongoing management and future challenges

Tair Esenalı Uulu

Since its initial detection in Turkey in 2009, the invasive destructive pest South American tomato pinworm Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) has started its new invasion journey to east and invaded most Asian countries. This pest currently causes extensive damage to tomato production and potentially threatens key production areas such as China. To provide an overview of current status of T. absoluta in Asia, we have briefly reviewed the damage and economic impacts by this pest locally and discussed why this species has spread so rapidly among the countries. Moreover, ongoing i ...More

First report of charcoal rot caused by Macrophomina phaseolina on kiwifruit in Turkey

İsmail ERPER

During June and August in 2018, kiwifruit (cv. Hayward) plants exhibiting symptoms of charcoal rot including chlorosis, necrosis, leaf shedding, root rot, and trunk dry rot were observed with an incidence of up 5?n three commercial orchards located in Altınordu, Fatsa and Perşembe districts of Ordu province. After surface sterilization with 1?aClO, small pieces excised from root tissues of diseased plants were rinsed twice in sterile distilled water, dried on sterile filter papers and aseptically transferred to plates containing potato dextrose agar. Ten isolates from the plates were identifie ...More

Genetic Diversity in Apple Accessions Belong to Different Species Collected from Natural Populations of Tianshan Mountains, South-West Kyrgyzstan

Abdıkerim ABDULLAYEV

There isn't any concrete consensus about the origin of domesticated apple. However, it is generally thought that the origin of this apple primarily comes from M. sieversii, also known as Central Asia wild apple. The second significant contribution is thought to be supplied by M. sylvestris. Central Asia is an important origin region for apples. Within this region, mountainous and forestlands of Kyrgyzstan constitute a significant source for wild apple species. The present study was conducted to put forth the genetic relationships between 65 accessions belonging to M. kirgishorum, M. domestica, ...More

Agro-morphological traits of Cicer reticulatum Ladizinsky in comparison to C. echinospermum P.H. Davis in terms of potential to improve cultivated chickpea (C. arietinum L.)

Mirlan TALİP

Germplasm collections of C. reticulatum and C. echinospermum are limited, while both species face threats from over-grazing and habitat change in their natural environments. Recently many new accessions of C. reticulatum and C. echinospermum were collected in east and south-east Anatolia (Turkey) but they have not yet been evaluated for agro-morphological traits. Therefore, the current study investigated agro-morphological traits of new germplasm sources of C. reticulatum and C. echinospermum and evaluated resistance to biotic and abiotic stresses for chickpea improvement. The most attractive ...More

Synthesis and Characterization of Hydroxypropyl Acorn Starch (HPAS) From Oak Acorn

Mustafa DOLAZ

The utilization of forest auxiliary products and their conversion into products with higher added value is important for the use of renewable resources. For this purpose, acorns belonging to the Q. coccifera species were collected in November, which is their ripening period, and dried and ground in the laboratory. Then, acorn starch (AS) was isolated from the sieved acorn flour. For 5 g of this isolated AS, hydroxypropyl acorn starch (HPAS) with the highest molar substitution (MS = 0.319) was synthesized by optimizing at 45 degrees C for 5 h with 30 g of propylene oxide and 1.88 g of NaOH. The ...More
