摘要:

Agro-sylvicultural aspects of Lucania. In the Basilicata Region one can find many types of natural habitats from the mediterranean « macchia » to the rocky peaks of Monte Pollino. Natural environmental factors greatly condition land utilization and sub-spontaneous plant formations such as forests, opens scrubs, and grazing lands, occupy 49% of the productive land (53% in the Province of Potenza alone): this is a high figure as compared to the one for the whole of southern Italy (37.5%). Forested land is 18% of the total and also this value is higher than the corresponding one for the whole of southern Italy (14.4%). Cereals are the main crops: the economy of Basilicata is therefore mainly based on pastoral-cereals growing activities.

摘要:

On the basis of recent researches the main outlines of the Lucania geology are briefly discussed. The more typical landscapes of this region are then delineated, from that of the calcareous dolomitic mountains to those of the flysch, of the marine pliocene sediments, of the volcanic area (Vulture) and the marine and fluviatile pleistocene terraces of the metapontian littoral. The principal evolution trends of the pedogenesis are finally illustrated with some reflection on the very difficult problems of the soil conservation in this area.

摘要:

The vegetation of Lucania: an outline. – The vegetation of Lucania is outlined on the basis of the existing literature and of personal observations. After a short review of the botanical literature a new subdivision of this region is proposed taking into consideration both geological and botanical criteria. The various plant formations are described, among them: the vegetation of the sandy beaches along the Ionian Sea; the Policoro Forest on the coastal plain; theLygeum spartumstands on the clays; theQuercus centsforests, and theFagus silvaticaones (comprising the two associationsAquifolio-FagetumandAsyneumati-Fagetum);the relictAbies albastands; the summit prairies; thePinus leucodermisstands.

摘要:

An open question: the didactics of Sciences in the modem world. Here are mentioned the difficulties of the modern world to state the problem of didactics as far as a particular science is concerned, above all the Science of Nature. The difficulties are arising from the model of school our society is aiming at nowadays, the model of school completely different from that one of the past, it comes out the necessity to point out in which way the purposes of particular sciences have a place in that question.

摘要:

School and naturalistic education. In order that mankind may correctly fit in the balance of nature young people must be given the right scientific preparation during school years. This is why a better training of science teachers would be so important especially in Italy, where they come straight from University having followed various types of scientific degree courses, mainly theoretical, and with no special preparation for teaching.

摘要:

Plant genetic resources. I. The problem of the conservation of plant genetic resources emerges from the examination of the consequences of the genetic erosion and of the destruction of genetic variability, which provoke decline and disappearance of plant species, of agricultural value too.

摘要:

Plant genetic resources. II. The Author describes the actions to be undertaken for the conservation of the plant genetic resources, mainly in relation to the following methods: a) natural mass reservoirs where plant material may continue its processes of evolution, b) collections managed in such way that the genetic integrity of the original population is not eroded. Criteria, methodologies, studies, problems solved or to be solved are considered in the paper. Great attention is deserved to tactics of exploration and collection, to storage conditions, to seed physiology and life span of seeds, to information storage and documentation.
