Taxonomy, Morphology and Palynology of Aegilops Vavilovii (Zhuk.) Chennav
African Journal of Agricultural Research Vol. 5(20), pp. 2841-2849, 18 October, 2010 Available online at http://www.academicjournals.org/AJAR ISSN 1991-637X ©2010 Academic Journals Full Length Research Paper Taxonomy, morphology and palynology of Aegilops vavilovii (Zhuk.)

Accepted 23 September, 2010 Aegilops vavilovii (Zhuk.) Chennav., a rare species, was collected from Southeast Anatolia, Turkey. During the field studies of the project “Taxonomic revision of Tribe Triticeae in Turkey”, Ae. vavilovii was accidentally recollected from three localities in anliurfa and Mardin provinces in 2007 and 2008, respectively. The main objective of this study is to shed light on the diagnostic characteristics of this rare species including its morphological, palynological and micro morphological features. Moreover, an emended and expanded description, distribution, phenology and ecology of this rare species are also provided. A. vavilovii and A. crassa are naturally found in the Southeastern part of Turkey and they share similar morphological features that caused a confused taxonomy. Pollen grains of A. vavilovii are heteropolar, monoporate and spheroidal (A/B: 1,13) typically as Poaceous. However, it generally, prefers clayish loam soils that are slightly alkaline (pH 7.7) with low organic content (1.54%). Although it is a rare species with very narrow area of distribution, very few samples have been represented in ex situ collections and the species has not been involved in any in situ conservation activities to save its genetic resources in Turkey. -

Evaluation of Agro-Morphological Diversity in Wild Relatives of Wheat Collected in Iran
J. Agr. Sci. Tech. (2017) Vol. 19: 943-956 Evaluation of Agro-Morphological Diversity in Wild Relatives of Wheat Collected in Iran A. Pour-Aboughadareh1*, J. Ahmadi1, A. A. Mehrabi2, M. Moghaddam3, and A. Etminan4 ABSTRACT In this study, a core collection of 180 Aegilops and Triticum accessions belonging to six diploid (T. boeoticum Bioss., T. urartu Gandilyan., Ae. speltoides Tausch., Ae. tauschii Coss., Ae. caudata L. and Ae. umbellulata Zhuk.), five tetraploid (T. durum, Ae. neglecta Req. ex Bertol., Ae. cylindrica Host. and Ae. crassa Boiss) and one hexaploid (T. aestivum L.) species collected from different regions of Iran were evaluated using 20 agro- morphological characters. Statistical analysis showed significant differences among accessions. The Shannon-Weaver (HʹSW) and Nei’s (HʹN) genetic diversity indices disclosed intermediate to high diversity for most characters in both Aegilops and Triticum core sets. In factor analysis, the first five components justified 82.17% of the total of agro- morphological variation. Based on measured characters, the 180 accessions were separated into two major groups by cluster analysis. Furthermore, based on the 2D-plot generated using two discriminant functions, different species were separated into six groups, so that distribution of species accorded with their genome construction. Overall, our results revealed considerable levels of genetic diversity among studied Iranian Aegilops and Triticum accessions, which can open up new avenues for rethinking the connections between wild relatives to explore valuable agronomic traits for the improvement and adaptation of wheat. Keywords: Aegilops, Multivariate analysis, Phenotypic diversity, Triticum. INTRODUCTION traits, such as disease- or pest-resistance and even yield improvement. -

Here, we report accurate estimates of genome size in 99 accessions from 26 species of Avena . We demonstrate that the average genome size of C genome diploid species (2C=10.26 pg) is 15% larger than that of A genome species (2C=8.95 pg) and that this difference likely accounts for a progression of size among tetraploid species, where AB < AC < CC (average 2C=16.76 pg, 18.60 pg, and 21.78 pg, respectively). -

Khafagi(3), Nashua A.M. Mostafa(1) (1)Department of Botany and Microbiology, Faculty of Science, El-Arish University, N. Sinai, Egypt; (2)The Herbarium, Botany Department, Faculty of Science, Cairo University, Giza, Egypt; (3)Botany Department, Faculty of Science, Al-Azhar University (Girls Branch), Cairo, Egypt. ANUALLY constructed keys for identification of plants leave much to be desired. Keys Mto the Asteraceae of Egypt are no exception and depend largely on floral minutiae while vegetative morphology is a much richer source of characters suitable for key construction. Inspection of some 3000 specimens showed that the most obvious feature of the plants is the presence or absence of spines on leaves, leaf axils, stem internodes, margins of stem wings and phyllaries. This feature was selected to divide species of this family into two main groups: spiny and spineless. Nomenclature of all taxa was updated and those with names reduced to synonyms of others were eliminated. This article deals only with the 65 species belonging to 20 genera of the first group. A total of 51 characters describing variation in spine distribution and other characters of vegetative morphology were recorded for each of the 65 spiny species and the key-generating program DELTA was applied to the data matrix. The result is a much improved automated key, a detailed description of every species in terms of the entire set of 51 characters, and the same description but in terms of the serial numbers assigned to these characters and their states. -

Aceto-iron-hematoxilin staining method was used to stain chromosomes. For each accession, chromosome characteristics including long and short arms, chromosome lengths, arm ratio index and relative chromosome lengths were measured using micro measure 3.3 software. Results revealed that all of the studied accessions were tetraploid (2n = 4x = 28) and consisted of 13 pairs of metacentric and one pair of submetacentric chromosomes, of which two pairs were satellite chromosomes. Karyotype formula for these accessions were 13 m + 1 sm. Arm ratio index value of chromosomes ranged from 1.11 in chromosome number 6 to 1.77 in chromosome number 12. The B chromosomes were not seen in any of the accessions. -

Hunter School of Human & Environmental Studies, University of New England NSW 2351, AUSTRALIA Email: [email protected] Abstract: The vegetation of Basket Swamp National Park (2820 ha), 30 km north east of Tenterfield (28°54’S, 152°09’E) in the Tenterfield Shire, in the Northern Tablelands Bioregion NSW, is described. Seven vegetation communities are mapped based on survey of plots, subsequent ground-truthing, air photo interpretation and substrate. Communities described are: (1) Eucalyptus campanulata (Blackbutt) – Eucalyptus cameronii (Diehard Stringybark) Open Forests, (2) Eucalyptus campanulata (Blackbutt) – Eucalyptus cameronii (Diehard Stringybark) Grassy Open Forests, (3) Leptospermum trinervium (Tea-tree) – Leptospermum polygalifolium subsp. transmontanum (Creek Tea-tree) Riparian Scrub, (4) Leptospermum trinervium (Tea-tree) – Kunzea obovata (Pink Kunzea) – Leptospermum novae-angliae (New England Tea-tree) Heaths & Shrublands, (5) Ceratopetalum apetalum (Coachwood) – Lophostemon confertus (Brush Box) Closed Forest, (6) Eucalyptus obliqua (Messmate) – Eucalyptus campanulata (Blackbutt) Tall Open Forests, and (7) Baeckea omissa (Baeckea) – Baloskion stenocoleum (Sedge) Heathy Sedgelands. All but two communities (3 & 7) were considered adequately reserved locally, no listed endangered or vulnerable commu- nities were found. Thirty-six taxa were considered to be of conservation significance of which two are listed as vulnerable on Schedule 2 of the NSW TSC Act. A further nine have been reported under the RoTAP criteria.
