A decade of European field trials with genetically modified plants.
This article analyzes the development of notifications of genetically modified plants field trials in the European Union from 1991 to 2001, based on the data collected at the European level in the Summary Notification Information Format database. During this time period, a total of 1687 field trial notifications were received. The number of field trial notifications dropped by 76% between 1998 ...
متن کاملAn Introduction to the Field Trials Methodology
The knowledge related to the methodology of the field trial study as a type of intervention studies, yet for many of our researchers is not fully understood. The aim of the current study was a better understanding of conducting this type of research. Field trial studies are done on healthy individuals and aim to prevent. These types of studies such as clinical trials are performed on both i...
متن کاملLife span correlates with population dynamics in perennial herbaceous plants.
Survival and fecundity are basic components of demography and therefore have a strong influence on population dynamics. These two key parameters and their relationship are crucial to understand the evolution of life histories. It remains, however, to be empirically established how life span, fecundity, and population dynamics are linked in different organism groups. We conducted a comparative s...

متن کاملEpigenetic regulation of bud dormancy events in perennial plants
Release of bud dormancy in perennial plants resembles vernalization in Arabidopsis thaliana and cereals. In both cases, a certain period of chilling is required for accomplishing the reproductive phase, and several transcription factors with the MADS-box domain perform a central regulatory role in these processes. The expression of DORMANCY-ASSOCIATED MADS-box (DAM)-related genes has been found...
