EXTERIORIZATION OF PRODUCTION CHARACTERS UNDER THE INFLUENCE OF CLIMATIC CONDITIONS FROM TIMISOARA IN SOME FOREIGN VARIETIES OF DACTYLIS GLOMERATA PUBLISHED

Mihaela Corcheş, Alexandru Moisuc
Knowing the characteristics of the varieties of fodder have a great importance for growers, as only knowing can be recovered. The varieties of fodder plants must meet very different requirements of soil and climate, because is necessary to produce feed in any climate, any type of soil, dry or wet areas, in warm or cold zones, in irrigated and non-irrigated. This wide range of requirements can be covered by zoning of fodder plant species and within each species, by zoning varieties. This paper presents the behavior of foreign genotypes of Dactylis glomerata (cocksfoot), in pedo-climatic conditions of Timisoara, in the perspective of enriching the current assortment of fodder plants varieties.  Experiences with varieties or hybrids have a permanent character, because for most species cultivated, in every year occur new varieties and hybrids both nationally and internationally, which require testing before being introduced into culture of a given area. These experiences have as main purpose, identifying the most valuable varieties in terms of growing capacity, quality and other traits of agricultural interest. The research was carried out in the experimental fields of discipline of Culture of grasslands and fodder plants, USAMVB Timisoara, the experience being placed on a chambic chernoziom weakly gleyed soil type, with salinisation in depth. Biological material studied is represented by three foreign varieties ofDactylis glomerata (cocksfoot), namely AMBA, AMERA and OTELLO. Experience is placed after the method of randomized blocks in three repetitions.  A parcel surface is 20 m 2 (5m x 4m). Assessment of quantitative characters of the production was based on biometric measurements from 10 plants in each plot - repetition. Thus, was made determinations on plant about morphological characters, namely: the length of vegetative and generative shoots, the number of vegetative and generative shoots, the number of green leaves/ vegetative and generative shoots, weight of shrubs and leaf area /shoot. The data calculation and interpretation obtained from the performance measurements and calculations mentioned above were processed by conventional methods of statistical analysis.The significance of differences between graduations and combinations of various factors has been established through analysis of variance and u test.
