In evaluations of clover performances on summer-dry Himatangi sandy soil, it was found that none could match lucerne over summer. Emphasis was therefore placed on production in autumn-winter- early spring when lucerne growth was slow. Evaluations of some winter annual clover species suggested that Trifolium spumosum, T. pallidum, T. resupinatum, and T. vesiculosum would justify further investigation, along with T. subterraneum which is already used in pastures on this soil type. Among the perennial clover species, Kenya white clover (7'. semipilosum) showed outstanding recovery from drought and was the only species to produce significantly in autumn. However, it failed to grow in winter-early spring. Within red clover, materials of New Zealand x Moroccan origin substantially outproduced the commercial cultivars. Within white clover, material from Israel, Italy and Lebanon, as well as progeny of a selected New Zealand plant, showed more rapid recovery from drought stress and subsequently better winter growth than New Zealand commercial material ('Grasslands Huia'). The wider use of plant material of Mediterranean origin and of plants collected in New Zealand dryland pastures is advocated in development of clover cultivars for New Zealand dryland situations.

Floodplain valley of the Dnieper river midstream is a unique natural complex, having a great bìogeographical, ecological, environmental, historical and recreational values. In 1990, the Natural reserve «Dniprovsko-Orilsky» was established within the area. The Natural reserve «Dniprovsko-Orilsky» is environmentally protected site within the Dnipropetrovsk region, Dnipropetrovsk oblast, Ukraine. This reserve occupies part of the Dnieper river valley and marshy and reedy banks of Protovch river (existing bed of Oril river). It was created by Regulation of the Council of Ministers of the USSR of 15 September 1990, No. 262, based on common zoological and ornitological Nature reserves «Taromskì plavni» and «Obukhovskie zaplavy». On the territory of the Natural reserve «Dniprovsko-Orilsky», they were registered 32 Lepidoptera species listed in the List of Threatened Species at different categories (5 species in IUCN Red List ; 18 in Red Data Book of Ukraine; 7 in European Red List of plants and animals endangered on a global scale; 31 in Red Book of Dnipropetrovsk oblast). The main scientific materials were author’s collections from area of research and materials of entomological funds, Department of Zoology and Ecology, Oles Honchar Dnipropetrovsk National University (mostly Memorial Collection of V. O. Barsov). Field surveys covered all the ecosystems basic on size and degree of protection. The author’s researches have conducted over the past decade during annual expeditions to the Reserve. Taxonomic structure of the complex is quite diverse, and represented by all the major families of higher millers and rhopalocera, having protectedstatus. In relation to taxonomy, this complex formed by representatives of five superfamilies (Zyganoidea, Noctuoidea, Bombycoidea, Hesperioidea, Papilionoidea) from 11 families (Zygaenidae, Saturniidae, Sphingidae, Noctuidae Arctiidae Hesperiidae, Papilionidae, Pieridae, Nymphalidae, Satyridae, Lycaenidae). High taxonomic diversity can be explained by unique geographical location of the reserve in azonal conditions of the Dnieper river valley. Such location allows to enter different zoogeographic Lepidoptera groups on the reserve territory. Zoogeographic analysis of species protected within the reserve territory selected 7 basic groups. It was found that most of the globally rare species have Mediterranean origin (39 %); species of Palearctic origin are in second place (22 %); Western Palearctic and Ponto-Kazakh types of areas are same of number of species, and come third (11 %); and others come 17 % (European, Euro-Siberian, and Holarctic). This fauna component is specific due to presence of so-called «northern» species that make up 40 % (representatives of Palearctic, Western Palearctic, Euro-Siberian, European and Holarctic groups). Their existence within the reserve territory is only possible due to development of boreal valley ecosystems.

The article analyzes the ceramic imports found on the territory of the Meroitic Kingdom – the southern neighbour of Egypt, which existed on the territory of modern Sudan since the second half of the 6th century B.C. until the middle of the 4th century A.D. The imported pottery revealed in the process of archaeological excavations of necropoleis, residential and temple complexes are mainly of Mediterranean origin and are associated with the Hellenistic world that later became a part of the Roman Empire. The finds are mostly rare and are represented by fragments of amphorae from various regions of Italy, Aegean region, Asia Minor, the Levant, northern Africa, as well as the European provinces of the Roman Empire – Baetika and Gaul. The main consumer of foreign goods, in small numbers reaching the middle and upper reaches of the Nile, was probably the Meroitic elite. It is logical to assume that the penetration of Mediterranean ceramics into Meroe was facilitated by the trade ties of its northern neighbour – Egypt:trade with the Mediterranean took place through Egyptian river and caravan routes; although hypothetically, one cannot exclude the possibility of goods entering Meroe bypassing Egypt, through the Red Sea ports. Despite a small share of imported products in the Meroitic Kingdom and regardless of the ways of their movement, they had a significant influence on the local pottery manufacturing; a reflection of this process was the appearance in the African kingdom of Hellenistic forms of vessels (kraters, askoses, lekythoi, clepsydras, etc.) and vase painting in the Greek style. As a result, a very special synthesis of artistic ideas emerged, embodied in Meroitic ceramics. Along with the local Nubian features, Egyptian and Hellenistic themes, techniques and ceramic forms are recognized there, which are characteristic for the pottery of Late and Ptolemaic Egypt, ancient Greece and Rome and allows us to see the Kingdom of Meroe as the extreme southern outpost of the Hellenistic world.

Controlled Flowering

Hybrids were produced between seven different parents of Mediterranean origin and two parents of Northern European origin. A special technique of controlled flowering, emasculation, and pollination was used to effect the hybridization. Hybrid plants were grown in undefoliated swards and assessed for cumulative growth, variation in the reproductive phase, tillering, and summer survival. The combining abilities of the parents were estimated for these characters. Hybrids between Mediterranean and Northern European parents were able to respond to summer showers at a time when Mediterranean material was still summer dormant and Northern European material severely affected by dry summer conditions. This out-of-season growth was reflected in the higher yields of the hybrids in the autumn after the main start to the growing season. During midwinter when the Mediterranean material was growing actively the growth of Northern European material ceased and some combinations of Mediterranean and Northern European parents ceased growing. The cessation of growth was attributed to winter dormancy. Plant survival during the summer was 97% for the purely Mediterranean families, 88% for Mediterranean x Northern European families, and 59% for the purely Northern European families. Some of the Mediterranean x Northern European families survived as well as the best Mediterranean families. The potential agricultural value of the Mediterranean x Northern European hybrids and a possible breeding programme with them are discussed.

Cold Requirement

The responses of annual and perennial ryegrass to 0, 6, and 12 weeks artificial seed vernalization were determined by recording the percentages of plants heading and the leaf numbers at heading for populations of 40 plants grown in a glasshouse under continuous light. All plants of the annual L. rigidum headed without vernalization but the vernalized plants headed at a much lower leaf number than did the unvernalized controls. At least six weeks of cold treatment were needed for complete induction of the five cultivars of L. perenne examined. The vernalization responses of cultivars of Mediterranean origin were similar to those of the Australian Colac. It was shown that late heading in L. perenne is not always associated with a large cold requirement and it is suggested that photoperiod may be an important factor controlling heading of ryegrass in southern Australia.
