Four species shows new chromosome count from world as well as India level. Agrostis pilosula (2n=28), Polypogon monspeliensis (2n=56) and Eragrostis viscosa (2n=32) are the first chromosome reports in the world, whereas, Diplachne fusca (2n=20) is the first report from India. The meiotic course of all the investigated plant species is normal with high pollen fertility. Key words Agrostideae, Eragrosteae, Male meiosis, Pollen fertility.

  • Micromorphological Variations and Taxonomic Implications Of
    Wulfenia 27 (2020): 86 –96 Mitteilungen des Kärntner Botanikzentrums Klagenfurt Micromorphological variations and taxonomic implications of caryopses of some grasses from Pakistan Anwer Usma, Mushtaq Ahmad, Muhammad Zafar, Shazia Sultana, Lubna, Nomana Kalsoom, Wajid Zaman & Fazal Ullah Summary: In this study, 13 taxa of Poaceae were studied regarding morphology of caryopses. Micro- and macromorphological characters were observed in detail by light microscope (LM) and scanning electron microscope (SEM). Size of caryopses in selected taxa ranged between 0.5 –9.2 mm length and 0.7– 4 mm width. Different colors of caryopses (whitish brown, yellow, green and brown) with linear oblate, obovate, round, shallowly obtriangular and elliptic shapes were recorded. Depressed and grooved hila were observed. Dorsiventral and lateral types of caryopsis compression were found. Significant patterns were noted on the surface, such as rugose, scabrate, reticulate, striate, scaberulous and papillate. Bulges, silica cells, prickles, spines, bicellular micro hairs and granules were analyzed as epicuticular projections. Periclinal and anticlinal wall patterns, texture and thickness were studied. The present study focuses on caryopsis morphology of Poaceae and their taxonomical importance in the identification of thirteen species. Keywords: caryopsis characters, microscopy, morphology, Poaceae, taxonomy Grasses are distributed more commonly than any other taxa of flowering plants. They have a great adaptability, which enables them to grow under different conditions. They occur frequently in the semi-arid prairies of the American continent, steppes of Asia and the savannas of Africa. Poaceae are economically very important, because of providing cereal species as well as forage plants for animals (Gautam et al. 2018). Taxa of Poaceae constitute a natural homogenous group of plants.

  • Taxonomic Inventory of Grasses on the Basis of Morphological Attributes from Thal Desert, Pakistan
    International Journal of Scientific & Engineering Research, Volume 4, Issue 11, November-2013 509 ISSN 2229-5518 Taxonomic inventory of grasses on the basis of morphological attributes from Thal desert, Pakistan Sunbal Khalil Chaudhari, Muhammad Arshad, Muhammad Shoaib Amjad, Sammer Fatima Abstract— Grasses constitute a natural homogenous group of plants belonging to the family Poaceae (Gramineae). Undoubtedly, Poaceae forms the most fascinating families of flowering plants, with a wide range of diversity and plays a significant role in the lives of human beings and animals. Thal Desert of Pakistan has rich diversity in grasses and various habitats are available for their growth, and these grasses are less exploited as far as taxonomy is concerned. In this study, morphological analysis of 29 grass species belonging to 10 different tribes was carried out. These Species were distinguished at tribe level and at individual level by apparent morphological features such as height, leaf blade appearance, inflorescence type, ligule, glumes, lemma, palea , number of awn extensions etc. Arundo donex belonging to tribe Arundineae has lacerate membranous ligule which is a unique characteristic from other members of same tribe. Tribe Aristideae members have trifid awn extension. Enneapogon shimpranus, member of tribe Pappophoreae has 9 awned lemma. These different morphological characteristics of grasses help in discriminating between closely resembling species of Poaceae and can be used in further taxonomic studies carried out on these species.

  • Nara Desert, Pakistan Part I: Soils, Climate, and Vegetation
    Nara Desert, Pakistan Part I: Soils, Climate, and Vegetation By Rahmatullah Qureshi and G. Raza Bhatti Introduction Rangelands constitute an important component of the agricul- tural system in Pakistan. Besides providing grazing support for the 93.5 million livestock, they are a major source of fuel and timber and natural habitat for wildlife. Because of the arid and semiarid environment and limited irrigated facilities, these areas cannot be converted into cropland. However, this vast natural resource covering over 60% of the country provides great potential for livestock grazing and dry afforestation. A range management program was initiated for the first time in Pakistan with financial and technical assistance of the U.S. government in Baluchistan province.1 This project provided a base to identify the problems and their possible solutions by policymakers and natural resource mangers. A A view of stabilized sand dune with dense population of Aerva javanica, number of research-and-development projects for range Calligonum polygonoides, and Dipterygium glaucum. management were launched in different ecological zones. These initial projects were based on a demonstration of water harvesting and sand dune stabilization techniques.

TAXONOMIC APPLICATION OF FOLIAR ANATOMY IN GRASSES OF TRIBE ERAGROSTIDEAE (POACEAE) FROM SALT RANGE OF PAKISTAN FAROOQ AHMAD1, MIR AJAB KHAN, MUSHTAQ AHMAD, MANSOOR HAMEED1, RASOOL BAKHSH TAREEN2, MUHAMMAD ZAFAR AND ASMA JABEEN3 Department of Plant Sciences, Quaid-i-Azam University Islamabad, Pakistan 1Department of Botany, University of Agriculture, Faisalabad, Pakistan 2Department of Botany, University of Balochistan, Quetta, Pakistan 3Environmental Sciences Program, Fatima Jinnah Women University, Rawalpindi-Pakistan E-mail: [email protected] Abstract Foliar anatomical investigations of some members belonging to tribe Eragrostideae (Poaceae) were carried out. In total of 8 species belonging to 6 genera were collected in wild from Salt Range region of Pakistan for anatomical studies. Maximum length of long cells was observed in genus Eragrostis. Macrohairs are found absent in all species except Eragrostis papposa. Acrachne racemosa is identified by dumb bell shaped or cross shaped silica bodies while saddle shaped silica bodies are present in other species. Desmostachya bipinnata is distinct by having a tall girder of bulliform cells, from adaxial to abaxial side. Microhairs with hemispherical distal cell, saddle shaped silica bodies and bulliform cells deeply penetrating the mesophyll are the diagnostic characters, which justify all the species in the same tribe. Introduction vascular bundles in the blades appears to be a useful diagnostic character above the generic level (Ellis, 1976). Tribe Eragrostideae (Poaceae) is represented by about Grasses in tribe Eragrostideae look morphologically 50 genera in the world, found throughout the tropics. In similar and there is confusion in the identification, Pakistan 16 genera and 33 species of this tribe are differentiation and delimitation of species, genera and the reported (Cope, 1982).

  • A Laboratory Guide for Generating DNA Barcodes in Grasses: a Case Study of Leptochloa S.L
    Webbia: Journal of Plant Taxonomy and Geography, 2014 Vol. 69, No. 1, 1–12, http://dx.doi.org/10.1080/00837792.2014.927555 INVITED PAPER A laboratory guide for generating DNA barcodes in grasses: a case study of Leptochloa s.l. (Poaceae: Chloridoideae) Paul M. Petersona*, Konstantin Romaschenkoa,b and Robert J. Sorenga aSmithsonian Institution, Department of Botany, National Museum of Natural History, Washington, USA; bM.G. Kholodny Institute of Botany, National Academy of Sciences, Kiev, Ukraine (Received 29 March 2014; final version received 20 May 2014) There is no easy way to identify to species, a small, vegetative leaf or culm sample of a grass and there are more than 12,000 species in this large, important family. The long-range aim of our study is to produce a standard DNA barcode library available to the public for all grasses (±1960 species) in North America (includes all Canada, Mexico and USA) that will facilitate the easy identification of these morphologically cryptic species. We provide a detailed protocol of the laboratory procedures for DNA extraction in grasses and the DNA-specific primers used for the polymerase chain reac- tion (PCR) enabling the laboratory work to be performed in any well-supplied molecular laboratory. In this paper we present a test of four barcodes [matK, rbcL, rpl32-trnL and internal transcribed spacer (ITS)] to discriminate among 50 taxa of grasses (55 samples), predominately in the subfamily Chloridoideae, and we used a tree-based method to identify relationships among species of Leptochloa sensu lato. The sequence divergence or discriminatory power based on uncor- rected p-value, among the four DNA sequence markers was greatest in ITS (96%), followed by rpl32-trnL (25.6%), matK (3.0%) and rbcL (0.0%).

  • 1. Introduction Grasses Are Very Important Group of Plants Not Only to Human Beings but Also to Animals
    1. Introduction Grasses are very important group of plants not only to human beings but also to animals. Grass species are most of the world’s major food crops, including wheat, barley, oats, rice, maize, millets, sugarcane and pasture species. Grasses are also very important use as hay, so that various species cultivated in hay fields and for pastures. Many tall grasses, such as Bamboos are used as good construction material and plumbing as well as good raw material for the paper and various other things. Tuft and ornamental grasses are appreciated for their durability and beauty throughout the work. Apart from that grasses are used as a green fodder which the most important factor responsible for the success of animal husbandry. Natural grasslands play an important role in supplying fodder to the animals. These fodder grasses are known as palatable grasses. Dicanthium annulatum Bothriochloa pertusa, Sehima nervosum, Sehima sulcatum, Chrysopogon fulvus are highly palatable grasses while Ophiuros exaltatus, Desmostachya bipinnata, Heteropogon contortus, Imperata cylindrica, Aristida adscensionis, Aristida funiculata, Dinebra retroflexa are unpalatable grasses (Gandhi et al., 2011). Other than this, few grasses are used by humans as food. Paspalum scorbiculatum grains and flour are used by tribals (Gandhi et al., 2011). Grass species are ubiquitous on earth, occurring in ecosystems on every continent and when they form grasslands, they have a major influence on climate through the cycling of carbon and water between soils and the atmosphere. The influence of climate on grasses therefore lies at the heart of several important scientific problems, including the evolution of grasses and grasslands.

  • Introduction
    Introduction Egypt is a part of the North African Desert. Its area is about one million km² divided by the River Nile into Western Desert of about 681,000 km² and an Eastern part comprising the Eastern (Arabian) Desert (223,000 km²) and the Sinai Peninsula (61,000 km²). The Nile region including the Nile Valley, the Nile Delta and the Nile Fayoum forms a riparian Oasis (40,000 km²) that is the densely inhabited farmlands of Egypt. From the earlier and most valuable works of Forsskal (1775), Delile (1813), Ramis (1929), the flora of Egypt is still under various taxonomical and floristic studies, the most important of these are those of Tackholm in collaboration with Drar, who presented four volumes of the Flora of Egypt (1941; 1950; 1954; 1969). Montasir and Hassib (1956) published also short account on the flora of Egypt. These are followed by Tackholm (1956 & 1974), Boulos (1995, 1999, 2000, 2002 and 2005). Boulos (1995) stated that the flora of Egypt comprises 2094 native and naturalized species under 712 genera and 121 families. The grasses are grouped into about 600 genera, with nearly 5,000 species worldwide. They have a wider range than any other family of the flowering plants. The grass family includes about 75 per cent of the cultivated forage crops and all the cereal crops (Hughes et al. 1962). In Egypt Gramineae (Poaceae) is the largest family which contains 277 species (including 27 cultivated species). Imperata cylindrica (L.) Raeush., Nomencl.
