To induce flower color mutants in Grasspea ( Lathyrus sativus Linn.) variety “Pusa-24“, the fresh seeds were exposed to 4 different doses of gamma radiation as physical mutagens (100, 200, 300 and 400 Gy) and treated with 4 different concentration of Ethyl Methanesulphonate as chemical mutagen (5, 10, 15 and 20 mM ) and also combination of both mutagens. Due to mutagenesis broad range of flower color mutants in M 2 , M 3 and M 4 were obtained. Various unique and different flower color mutations like pink, purple, white and yellow detected against blue which is natural color in control progenies. Maximum flower color frequency was recorded in EMS treated seeds (20 mM) in 4th generation and lowest mutation frequency in 2nd generation was obtained in gamma rays (100 Gy) treated seeds. The results showed more flower color mutations happened in more dose /concentration of mutagens in every generation

Abstract Hypericum perforatum L. (St John’s Wort) is a medicinal plant that produces pharmaceutically important compounds with antidepressive, anticancer and antiviral activities. H. perforatum is a facultative apomictic species as it has the ability to reproduce with multiple reproduction mechanisms affecting genetic structure and chemical composition of the plants. The objective of this study was to determine nuclear DNA content and ploidy of H. perforatum L. plants growing naturally in the flora of Turkey. The seeds of 39 Hypericum perforatum L. accessions collected from 23 different locations in Turkey were used in the study. Nuclear DNA content of three different seedlings for each of the 39 H. perforatum accessions was determined using flow cytometry. Based on the results of flow cytometric analysis, nuclear DNA content of the accessions varied between 0.8 - 2.57 pg2C -1 . Nuclear DNA content differences observed among H. perforatum accessions were statistically significant (P< 0.01) and the Duncan test revealed that the accessions formed three clearly distinguishable main groups. Mean nuclear DNA contents of each group were 0.80 pg2C -1 , 1.58 pg2C -1 (1.36-1.73 pg2C -1 ) and 2.38 pg2C -1 (2.15-2.57 pg2C -1 ). Ploidy levels were determined by correlating nuclear DNA content of accessions with the number of their mitotic chromosomes by counting chromosome number of one plant from each group. Findings suggest that H. perforatum accessions used in this study had the following three different ploidy levels: diploid, tetraploid and hexaploid. The percentage of diploid, tetraploid and hexaploid accessions was 2.2, 86.4 and 11.4% respectively.

The aim of this study was to determine the most suitable areas for small ruminant farming in the Karaburun area in Izmir province, Turkey. To this purpose, an inquiry model was first developed using remote sensing and a geographic information system. In developing the model, legal and technical factors were taken into consideration, and eight evaluation criteria (distance from settled areas, distance from lakes or similar water sources, distance from protected water catchment basins, distance from wind energy generators, distance from irrigation and drainage canals, slope, aspect – direction of slope – and land use class) and three evaluation classes in relation to these criteria (suitable, conditionally suitable and unsuitable) were planned. Later, the model was used to test the suitability of the study area in general and five sample farms in that area for suitability. According to all of the criteria of evaluation, 3.54% of the 42 707.15 ha 15 study area was found to be suitable for small ruminant farming, 2.78% was conditionally suitable, and 93.60% was unsuitable. As for the five sample farms in the study area, none of them was found to be suitable according to all of the evaluation criteria. In addition, suggestions were made for the functionality and effectiveness in use of the geography information inquiry models used in the choice of places for small ruminant farming.

This study was conducted to determine genotypic variation among sorghum cultivars grown under similar ecological conditions for seed vigor, NaCl and drought stresses. A seedling survival test was also performed in a pod experiment to investigate genotypic differences in terms of sorghum drought tolerance. In seven sorghum cultivars, seed vigor was determined using electrical conductivity and accelerated aging tests, and germination rate and seedling growth of these cultivars were evaluated under salt (NaCl) and drought stress induced by PEG 6000 at water potentials of 0.0, 1.8, 3.6, 7.2 and 10.8 bar. The results showed that seed vigor differed among sorghum cultivars and the highest correlation coefficients were determined between laboratory emergence and accelerated aging (r=0.967**), and between germination and electrical conductivity (r=-0.873**). Electrical conductivity found a suitable test for determining germination potential of sorghum seed lots while the best method predicting emergence percentage was accelerated aging. Germination was delayed in both NaCl and PEG solutions. Germination, root length and shoot length were higher, whereas mean germination time was lower, in NaCl solution compared to in PEG solution at the same water potential. The most and least vigorous seeds were observed in the Akdari and Gozde 80 cultivars, which displayed the lowest germination percentages in NaCl and PEG solutions. From this study, it could be concluded that seed vigor is not a reliable indicator of germination performance under salt and drought stress conditions and that genetic differences may play an important role in stress tolerance.

The most and least vigorous seeds were observed in the Akdari and Gozde 80 cultivars, which displayed the lowest germination percentages in NaCl and PEG solutions. From this study, it could be concluded that seed vigor is not a reliable indicator of germination performance under salt and drought stress conditions and that genetic differences may play an important role in stress tolerance.","PeriodicalId":22215,"journal":{"name":"Tarim Bilimleri Dergisi-journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81652595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
In the present study, we used the TUB-GFP and MBD-GFP of the Arabidopsis thaliana , compared with effects of the plant height and primary root length, and changes of microtubules dynamics by confocal laser scanning microscope after UV-B radiation. It was shown that UV-B radiation had the same damaged effects on the transgenic lines, compared with wild type, and the transgenic lines were more sensitive for UV-B. MBD-GFP Arabidopsis thaliana could be better adapted to the changes with UV-B treatment. Therefore, these results indicated that UV-B could inhibit the growth and the development of transgenic Arabidopsis thaliana , and the inhibition effects might result from changes in microtubules.

The seasonal changes of carbohydrate content were monitored in the leaves of ‘Okitsu’, ‘Clausellina’, and ‘Silverhill’ satsuma cultivars budded on the sour orange (Citrus aurantium L. var. Yerli), Carrizo and Troyer citranges (Poncirus trifoliata Raf. x Citrus sinensis Osb. var. Troyer and Carrizo) during the 2010 and 2011 seasons. The seasonal changing trends of leaf soluble sugar contents of 3 satsuma cultivars budded on different rootstocks were similar. The sucrose was the most abundant soluble sugar. Carbohydrate contents had a maximum level at dormant period, and remained at low level during summer. In this period, the sharp decrease in leaf total carbohydrate concentration of ‘Okitsu’, ‘Clausellina’ and ‘Silverhill’ occurred in April with a rate of 27.9%, 22.6% and 21.0%, respectively. Accumulation of carbohydrate in leaves generally started after mid summer and continued until the end of year. The rootstocks were found to be not significant for total soluble sugar, starch and total carbohydrate concentration in most of the months. The cultivars had a significant effect on carbohydrate fractions of leaves compared to rootstocks. The scion-rootstock combination was significant on total carbohydrate concentration of leaves in all months investigated.
