Somatic Embryogenesis in Juniperus Procera Using Juniperus Communis As a Model
Seblework Belaineh (MEJS) Volume 1 (2):95-105, 2009 Somatic Embryogenesis in Juniperus Procera using Juniperus Communis as a Model Seblework Belaineh Institute of Biodiversity Conservation, P.O. Box 30726, Addis Ababa, Ethiopia ([email protected]) ABSTRACT The study of somatic embryogenesis in Juniperus communis has been conducted as a preliminary study for the further development of somatic embryogenesis, micropropagation and long-term conservation/cryopreservation in Juniperus procera, which is economically and ecologically important and endangered forest species in Ethiopia. The aim for this particular research was initially an adaptation of optimum half strength lithium chloride-sodium propionate (LP) medium protocol for growth and proliferation of embryogenic culture. But as other conifer species it was difficult to stop proliferation of somatic embryo cell division and bring them to maturation stage. However using optimal concentration of ABA (32 mg/l), it was possible to get maturation response in most of the cultures. Additional study on the effect of seed extraction to the growing embryogenic culture showed no effect on mature somatic embryos. Rather they were showing faster growth which increases embryogenic mass of each culture. It was also observed that green premature seeds of Juniperus are suitable for the initiation and proliferation of somatic embryo. Key words: Cryopreservation, Juniperus communis, Juniperus procera, Somatic embryogenesis. 1. INTRODUCTION Juniperus procera is an evergreen dioecious, more seldom monoecius tree, which belongs to the family Cupressaceae. It is the tallest/largest juniper tree in the world (Pohjonen and Pukkala, 1992; Negash, 1995). It has two developmental phases, the juvenile and the adult stage. They are characterized by their distinctive trunk and crown shapes. -
Vegetation Succession Along New Roads at Soqotra Island (Yemen): Effects of Invasive Plant Species and Utilization of Selected N

The vegetation along the roads was disturbed and the erosion started immediately after the disturbance caused by the road construction. Our assumption is that biotechnical measurements should prevent the problems caused by erosion and improve stabilization of road edges. The knowledge of plant species which are able to grow in unfavourable conditions along the roads is important for correct selection of plants used for outplanting. The vegetation succession was observed using phytosociological relevés as a tool of recording and mapping assambblages of plants species along the roads as new linear structures in the landscape. Data from phytosociological relevés were analysed and the succession was characterised in different altitudes. The results can help us to select group of plants (especially shrubs and trees), which are suitable to be used as stabilizing green mantle in various site conditions and for different purposes (anti-erosional, ornamental, protection against noise or dust, etc.). -

Elharthi(1) (1)Biology Department, Faculty of Science, Taif University, Taif, Saudi Arabia; (2)Botany Department, Faculty of Science, Kafr El-Sheikh University, Kafr El-Sheikh, Egypt. HE PRESENT study aimed at surveying and identifying plant species distributed in the Tmain valleys at high altitudes in the study area, analyzing their vegetation, depicting the prevailing plant communities and assessing the role of the environmental conditions that affect the communities. Seventy-five stands were selected to represent the the vegetation physiognomy and the accompanying environmental variations. The species abundance, life forms, chorotype, and economic uses were determined. The total number of recorded species is 165 species belonging to 128 genera and 47 families. About 69.7% of these species are perennials and 30.3% were annuals. Poaceae and Asteraceae had the highest contributions to the total flora. Chamaephytes had the highest contribution, followed by therophytes, phanerophytes, hemicryptophytes and geophytes, while hydrophytes and parasites had the lowest contribution. The economic uses of the recorded species could be arranged in descending order as follows: medicinal > grazing > fuel > human food > other uses. The mono-regional and bi-regional species were the highest, while pluri-regional and cosmopolitans were the lowest. Of the mono- regionals, 36 species were Sudano-Zambezian, 17 species were Irano-Turanean and 16 species were Saharo-Arabian. -
Introduction
INTRODUCTION Section I: Bioactive Molecules from Mimusops elengi & Artemisia pallens Section II: Characterization of Molecules by Single Crystal X- Ray Diffraction Section I Bioactive Molecules from Mimusops elengi & Artemisia pailens 1.1 Ayurveda - The Art of Life Man has sought out plants with medicinal properties since ancient times. Evidence of this is the thousand years old traditions and records of proper healing. Traditional medicine (also known as indigenous or folk medicine) comprises medical knowledge systems that developed over centuries within various societies before the era of modern medicine. Traditional medicines include Unani system in Greece, Ayurvedic system in India, Amachi in Tibet, traditional Chinese medicine in China, Siddha or more recently Homoeopathy in Germany. Researchers are investigating not only the classical plants but also the related species that may contain similar active constituents as well as hitherto unknown plants which have no previous history of medicinal use\ Ayurveda is a holistic system of medicine from India that uses a constitutional model. Its aim is to provide guidance regarding food and lifestyle so that healthy people can stay healthy and folks with health challenges can improve their health. Ayurveda is an intricate system of healing that originated in India thousands of years ago. Vast ethno botanical knowledge exists in India from ancient time. Written records of the use of plants for curing human or animal diseases in India can be traced back to the earliest (4500-1600 BC) scripture of the Hindus, the Rigveda. Ayurveda, the Indian indigenous system of medicine dating back to Vedic ages (1500-800 BC), has been the integral part of Indian culture. -
The Birds of the Highlands of South-West Saudi Arabia and Adjacent Parts of the Tihama: July 2010 (Abba Survey 42)
THE BIRDS OF THE HIGHLANDS OF SOUTH-WEST SAUDI ARABIA AND ADJACENT PARTS OF THE TIHAMA: JULY 2010 (ABBA SURVEY 42) by Michael C. Jennings, Amar R. H. Al-Momen and Jabr S. Y. Haresi December 2010 THE BIRDS OF THE HIGHLANDS OF SOUTH-WEST SAUDI ARABIA AND ADJACENT PARTS OF THE TIHAMA: JULY 2010 (ABBA SURVEY 42) by Michael C. Jennings1, Amar R. H. Al-Momen2 and Jabr S. Y. Haresi2 December 2010 SUMMARY The objective of the survey was to compare habitats and bird life in the Asir region, particularly Jebal Souda and the Raydah escarpment protected area of the Saudi Wildlife Commission, and adjacent regions of the tihama, with those observed in July 1987 (Jennings, et al., 1988). The two surveys were approximately the same length and equal amounts of time were spent in the highlands and on the tihama. A number of walked censuses were carried out during 2010 on Jebal Souda, using the same methodology as walked censuses in 1987, and the results are compared. Broadly speaking the comparison of censuses revealed that in 2010 there were less birds and reduced diversity on the Jebal Souda plateau, compared to 1987. However in the Raydah reserve the estimates of breeding bird populations compiled in the mid 1990s was little changed as far as could be assessed in 2010. The highland region of south-west Saudi Arabia, especially Jebal Souda, has been much developed since the 1987 survey and is now an important internal recreation and resort area. This has lead to a reduction in the region’s importance for terraced agriculture. -

A total of 90 plots were established at three sites (Adelle, Boditi and Gaysay) at an altitudinal range of 3010–3410 m. The cover abundance values, density, and diameter at breast height and list of species were recorded in each plot. About 230 species belonging to 157 genera and 58 families were identified and documented. Analysis of vegetation data revealed 5 homogenous clusters. The densities of trees in the diameter class >2 cm were 766 and 458 individuals ha -1in Adelle and Boditi forests, respectively. The basal areas were about 26 and 23 m 2ha -1 in Adelle and Boditi forests, respectively. About 43% of the basal area in Adelle and 57 in Boditi forests were contributed by Juniperus procera and Hagenia abyssinica , respectively. Both Adelle and Boditi forests were found at an earlier secondary stage of development and had, more or less, a similar trend of development. -
Ethiopia October 30 - November 17, 2020
ETHIOPIA OCTOBER 30 - NOVEMBER 17, 2020 Comprising much of the Horn of Africa, Ethiopia is a poorly known but very beautiful country unlike any other part of the continent. On this new tour, you will discover that Ethiopia is culturally, scenically, and historically unique, and possesses a treasure trove of natural history wonders. Ethiopia, once synonymous with famine and desert, is actually dominated by a lush, fertile highland plateau occasionally referred to as “The Roof of Africa.” Ethiopia is an ancient land, home to lush highland forests, vast savannas, acacia thorn-scrub, the magnificent Ethiopian Rift Valley, and some of Africa’s highest mountains. Of the more than 850 species of birds recorded in the country, 37 either are endemic or near- endemic (the second largest total for any African country), among which are a number of captivating range-restricted species such as Rouget’s Rail, Prince Ruspoli’s Turaco, and the peculiar Stresemann’s Bush-Crow. In addition to its tremendous birdlife, Ethiopia hosts an impressive list of mammals including such remarkable endemics as Gelada Baboon, Mountain Nyala, and Ethiopian (Simien) Wolf. Our itinerary is designed with birds and other wildlife in mind, yet also offers a look at a broad slice of the country and its fascinating landscapes. We expect to encounter 400-500 bird species, and will make a special effort to locate as many of the endemic birds and mammals as possible. Enhancing the allure, this trip will operate in the boreal autumn when the diversity of the resident avifauna is augmented by the presence of large numbers of Palearctic migrants. -
