Excerpt from The Journal of Agricultural Science, Vol. 9: 1918-19 The seeds of many species of plants have a habit of germinating in un expected places under various conditions, and the question of the vitality of seeds is one that has frequently engaged the attention of. Scientists. It has often been claimed that seeds obtained from old pyramids and sepulchres have germinated when placed in favourable circumstances, but Becquerel1 states that strict enquiry and experiment show that authentic seeds of such origin will not germinate, but that the seeds so obtained which do germinate have proved to be frauds insetted by the fellaheen for the sake of gain. Various writers (quoted bv Becquerel) have claimed the power of germination for seeds buried for very long periods. Michelet elaimed that seeds of Galimn nlicum, buried 3000 years ago in the valley of Doubs, had retained their power of growth; von Held reich, that Glrmcium Serpieri from land covered by excavated scoriae 1500 years ago, was still viable; much doubt, however, has been thrown on the authenticity of such seeds. Information of this kind is of comparatively little value as evidence, as there is no definite proof of the time at which the seed actually reached its position or of the way in which it was transported. More satisfactory evidence has been obtained by the attempted germination of seeds of known age by various observers. Becquerel quotes experiments in which 500 species of seeds were sown, some of which were nearly 200 years old. Only four families gave any germination, Leguminosae, Nelumbifweae, Malvaceae, Labiatae. Cuminosae. 18 species germinated out of 90 sown. Ages 28-87 years. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Drylands have been cradles to some of the world’s greatest civilizations, and contemporary dryland communities feature rich and unique cultures. Dryland ecosystems support a surprising amount of biodiversity. Desertification, however, is a significant land degradation problem in the arid, semi-arid and dry sub-humid regions of the world. Deterioration of soil and plant cover has adversely affected 70% of the world’s drylands as a result of extended droughts as well as mismanagement of range and cultivated lands. The situation is likely to worsen with high population growth rates and accompanying land-use conflicts. The contributions to The Future of Drylands – an international scientific conference held under the leadership of UNESCO – address these issues and offer practical solutions for combating desertification along with conserving and sustainably managing dryland ecosystems. Major themes include the conservation of dryland biological and cultural diversity and the human dryland interface. This volume documents how our improved understanding of drylands provides insight into the health and future prospects of these precious ecosystems that should help ensure that dryland communities enjoy a sustainable future.
