Correlations between productivity elements in Lolium perenne L. species for new varieties resistant to drought
Perennial ryegrass is considered the most important perennial gramineous plant due to the many possibilities of use (grass and fodder) [6, 9, 15].With the increasing emphasis put on increasing the area of green space, obtaining new biological forms - varieties of the main species of gramineous plants for turf, with increased resistance to drought and land during the summer, may represent an important objective of the research companies producing such seed [6, 7].In the present study, are given researches on correlations between productivity elements, obtained in an experiment that simulates conditions of severe drought soil, to different genotypes of the species Lolium perenne L., which is …
RISK ASSESSMENT IN ROMANIA: FROM LEGISLATION TO NEEDS AND POSSIBILITIES
Ecological risk assessment (ERA) is an integral part of the environmental policy assumed by the Romanian Government, according to the standards of the European Union, to which our country hopes to be admitted in 2007.

Research on macrolepidoptera species (Insecta: Lepidoptera) collected in Dumbrava Sibului Forest (Romania) in conditions of the year 2011 and their status line in IUCN 2001 System
Macrolepidoptera fauna of Sibiu and its surroundings is studied for over 124 years by the naturalists Saxons. The collected material is preserved in the form of individual collections at the Natural History Museum in Sibiu. In addition to our material collected by us since 2001, data from these collections were a valuable documentary material for the present work. Our considerations on Macrolepidoptera flight periods are based on research conducted during the year 2011 from March to November in the protected area Dumbrava Sibiului. The natural conditions and the characteristics of the investigated area were revealed in several previous articles that could be found in the reference list. Thi…
