This is a database of 12,000 items compiled by Prof. G.M. Simpson, Plant Sciences Department, College of Agriculture, University of Saskatchewan. The Seed Bibliography covers material from the world literature on seed dormancy and germination from the 1890's to the present. Whereas recent publication on seeds is becoming very accessible through electronic indexes such as Agricola, CAB Abstracts, and Seed Abstracts, the significance of Prof. Simpson's database lies particularly in its coverage of the early literature. ...

Nels Lersten has retired from teaching, John Curtis plans to do the same very soon. Between the two of us we have over 60 years of plant anatomy teaching and research experience. We felt it would be a shame if the thousands of plant anatomy images we have taken for teaching and research were to retire with us. Therefore, we have put many of these images on this website with free access given to anyone interested. We have made no effort to give a balanced treatment of anatomy topics although most topics are represented. Because much of our research has been on plant secretory structures, this set of image reflects that bias. We hope that these images will be useful to people teaching (and taking) plant anatomy and related courses. ... [Information of the supplier]
The main objective of the Plant Ontology Consortium (POC) is to develop, curate and share controlled vocabularies (ontologies) that describe plant structures and growth and developmental stages, providing a semantic framework for meaningful cross-species queries across databases. The Plant Ontology (PO) has been developed and maintained with the primary goal to facilitate and accommodate functional annotation efforts in plant databases and by the plant research community at large. The initial releases of the PO integrated existing ontologies for Arabidopsis, maize and rice; more recent versions of the ontology encompass terms relevant to Fabaceae, Solanaceae and other cereal crops. As a part of the POC project, participating databases such as TAIR, NASC, Gramene and MaizeGDB have been using PO to describe expression patterns of genes and phenotypes of mutants and natural variants. The Plant Ontology Consortium (POC) is funded by the National Science Foundation. ... [Information of the supplier]
Mit seiner Elegie "Die Metamorphose der Pflanzen" macht Goethe uns auf eindrucksvolle Weise deutlich, wie gut wissenschaftliche Erkenntnis und dichterische Ausdrucksweise, zwei scheinbare Antithesen, in einer Synthese auf höherer Stufe vereinbar sind. Er eroberte hiermit auf zeitgemäße Weise Möglichkeiten zurück, wie die Antike sie besessen hatte, nämlich die Fähigkeit einer Lebensverbundenheit von Wissenschaft und Poesie. Goethe hat seine sachlich-empirischen Einsichten, die er durch Sehen und Beobachten gewonnen hat, nicht nur erkenntnistheoretisch angewandt, sondern zugleich auch naturphilosophisch und dichterisch gefaßt. ...

Scientific society “Modern Phytomorphology” was founded in 2011 in Lviv. The main aim of society is organisation and coordination of scientific conference and publishing of the journal. The second aim is preparing the seminars, field schools and educative work. Society held the scientists which are specialized on the investigations of the morphology and anatomy of the plants and fungi, and which exploit this data in other fields of botanical science. Society is international noncomercial organisation. The membership is closed. ... [Information of the supplier]
Researchers in legume taxonomy and systematics from around the world have joined forces to advance and propose a new updated family classification. In this context, the Legume Morphology Working Group (LMWG) was created primarily to contribute to the identification of morphological characteristics that are taxonomically and phylogenetically useful. The international symposium and workshop “Legume Morphology: Current Knowledge and Future Directions” is an important step towards achieving the general objectives of the LMWG: i) to support the work of the Legume Phylogeny Working Group (LPWG) towards developing the new classification of Leguminosae; ii) to evaluate how comparative morphological studies may help to better understand species groups, and poorly-resolved molecular phylogenetic relationships; iii) to identify gaps in our knowledge about legume morphology and coordinate efforts to fill these gaps; and, finally, iv) to promote consistency in legume morphological terminology for effective communication in the legume community, through an illustrated glossary including definitions that can be used widely as a standard reference. This event represents the first time that legume researchers focusing on legume morphology in and beyond South America reunite to advance legume systematics in a coordinated way. Furthermore, this event would be hosted by one of the countries with the highest legume diversity worldwide (221 genera and 2.800 species listed in the Flora of Brasil) and a long tradition of legume research. ...

The worldwide largest database and most comprehensive resource on pollen and palynology provides an Illustrated handbook of pollen terminology and 7957 pictures of 1011 recent species, belonging to 603 genera, and 124 pictures of 32 fossil forms, belonging to 20 fossil genera. The database includes a detailed description of the pollen grain (shape in dry and hydrated condition, apertural details, wall-stratification and ornamentation, pollen coatings and cellular condition), images of each pollen grain (LM, SEM and TEM) and basic literature on each genus. Search forms allow to query the database in any combination of pollen grain characters, including images and literature. Moreover, a number of print-outs are available, e.g., standardized pollen grain description of each taxon, literature and/or images to each genus, a key to a selected family, herbarium labels. ...

The Digital Seed Atlas of the Netherlands, which appeared in June 2006, consists of a book and a website. The atlas is the successor to W. Beijerinck’s seed atlas, of which the 1976 edition has been out of print for many years. The atlas consists of digital photographs, made with the help of a microscope, of the seeds and fruits of over 1800 native plants, adventive plants and naturalized cultivated plants. If relevant, both the front and the back of the seed is shown. In addition, for a large number of genera both the seeds and the fruits are shown. The order of the plant families in the Digital Seed Atlas follows the classification used in the new (23rd) edition of the Heukels’ Flora of the Netherlands. The book is in full colour and hardbound, in A4 size. Each page has 9 colour photographs of seeds and fruits. The atlas contains a total of over 4000 colour photographs. The introduction is in both English and Dutch; at the back of the book are indexes of the Dutch and the scientific names of the plants. On the website you can see all the photographs on a larger scale and in more detail. The website will offer search functions based on the taxonomy used and on the characteristics of the seed. This second option provides a user-friendly way to identify an unknown seed quickly. The origin of every seed is also specified on the website. Purchase of the atlas gives you the right to access the website, which will be managed by the University Library of the University of Groningen. Private individuals will have access to the website by means of a user name and password, institutions through IP address authentication so that all staff will automatically have access to the website without further identification. The Digital Seed Atlas is a treasury of information for everyone who wants to identify seeds and fruits. It will be of use to ecologists, plant taxonomists, palaeobotanists and amateur florists. ...

The Millennium Seed Bank Project is the largest ex situ conservation project ever conceived. Its partners will have banked seed from 10% of the world's wild plant species by the end of the decade. These will not be just any plants, but will include the rarest, most threatened and most useful species known to man. The Millennium Seed Bank Project seeks to develop a global seed conservation network, capable of safeguarding wild plant species. This will make direct contributions to national and global conservation/development programs, and will make a big contribution to meeting the objectives of the Convention on Biological Diversity (CBD). The current project runs until 2010. ... [Information of the supplier]
