The Effect of Some Endophytic Bacteria on Seedling Growth and Physiological Properties of Salvia Officinalis L
(Centenary University, 2023) Uçar, C.P.; Selem, E.; Tunçtürk, R.; Tunçtürk, M.; Akköprü, A.
In order to meet the demand for medicinal sage (Salvia officinalis L.), which is an important economic product, harvesting from nature has economic value. However, it may not always be of the desired standard and quality. Also, the harvesting from nature endangers their natural population causing their genetic base to decline. For this reason, it is important to produce it in an agrosystem and to increase yield in a sustainable way. In this study, the effects of eleven endophyte bacteria (EB) isolates applications on the development, morphology, and physicochemical properties of Salvia officinalis L. were investigated by climate chamber experiments. Peat+perlite+soil (1:1:2) mixture was used as the growing medium and EB was applied two times by soaking method. Effects of EB applications on shoot/root length, root/stem fresh and dry weight, Dualex values (Nitrogen balance index (NBI), flavonol, anthocyanin, and chlorophyll), leaf area, leaf temperature and color values (L*, a) *, b * C and Hue° were examined. All EB applications increased the plant height and leaf area. Also, the majority of EB isolates enhanced the root dry weight. The effect of EB applications on flavonol and chlorophyll content was not found statistically significant. However, there was a statistically significant increase in the nitrogen balance index (NBI). It was also observed that EB applications caused changes in plant color. According to the results obtained, it has been seen that it is possible to produce environmentally friendly and sustainable medicinal sage with appropriate plant-bacteria combinations. © 2023, Centenary University.

Karyological Analysis on Wheat Tir (Triticum Aestivum Var. Aestivum L. Spp. Leucospermum Körn.) Ecotypes in Lake Van Basin, Turkey
(Association of Agricultural Technology in Southeast Asia, 2022) Najafi, S.; Ulker, M.; Altuner, F.; Oral, E.; Ozdemir, B.; Jamal Salih, S.; Selem, E.
Karyotypic is studied within ecotypes species which are importantly found with different ecotypes, and it may possible showing specific genomic adaptation with their environmental growing conditions. Chromosome karyotype and morphology in wheat Tir by analyzing chromosomes in five ecotypes (Ahlat, Ercis, Muradiye, Patnos and central part of Van) in order to present the best instruction for cytogenetic studies in chromosome analysis was investigatred. Pre-treatment with %1 alpha-bromo naphthalene, fixation in karnoy 1, hydrolysis in NaOH and staining by %2 Aceto-Orcein were proved using root meristem segments followed by studying the microscopic preparations. Karyotype analysis of each ecotype. There was separately performed and showing several indices (TL: Total Length, LA: Long Arm, SA: Short Arm, Sat: Satellite and AR: Arm Ratio). The somatic chromosome numbers of all studied ecotypes are hexaploid with 2n=6x=42 and the averages of chromosomes length ranged from 4.60 ±0.02 µm to 16.05 ±0.02 µm. The longest chromosome was observed in chromosome number 1 from ecotype 3 which belongs to Muradiye and the shortest one was related to the chromosome number 21 from ecotype 4 from Patnos. © 2022 Association of Agricultural Technology in Southeast Asia.
