This study aims to evaluate the publications in ETRI Journal during the year 2010-2016. The data were retrieved from the web of science database maintained by Thomson Reuters, analyzed using tools like HisCite and Microsoft Excel.  The adopts various method like Relative growth rate, doubling time, Exponential Growth Rate, Average Authors per Paper, Degree of collaboration etc. focusing on various aspect of the journal such as document types, year wise distribution of publication, authorship pattern, authors productivity, institutions involved, relative growth rate, degree of collaboration, countries wise, most prolific authors of the journal and keyword wise distribution etc. The study reveals that ETRI journal has come out with 7volumes, 42 issues and total publications of 936 articles. The highest number of publications in terms of articles was in the year 2013 followed by 2012. The study shows that most of the papers (98.46%) were contributed jointly whereas (1.6%) papers were contributed by single authors. It reveals that Kim J is the most productive author contributing 58 (6.2%) of articles in ETRI journals. The country wise distribution shows that highest number of contribution comes from the South Korea itself a total record showing 656, (70.1%). ETRI itself is the top most contributors in ETRI Journal and the word “Based” is the most common key word used, with total of 228 (24.4%) records.

Seedlings of 24 European Scots pine (Pinussylvestris L.) populations were grown in controlled environment chambers under simulated photoperiodic conditions of 50 and 60°N latitude to evaluate the effect of seed mass on germination and seedling growth characteristics. Seeds of each population were classified into 1-mg mass classes, and the four classes per population with the highest frequencies were used. Photoperiod had minimal influence on seed mass effects. Overall, seed mass was positively related to the number of cotyledons and hypocotyl height. Populations differed significantly in seed mass effect on biomass. In northern populations (55–61°N), dry mass at the end of the first growing season was little affected by seed mass. However, dry mass in 9 of 15 central populations (54–48°N) and all southern (<45°N) populations correlated positively with seed mass. Relative growth rate was not related to seed mass within or across populations, and thus early growth is largely determined by seed mass. Relative growth rate also did not differ among populations, except for a geographically isolated Turkish population with the highest seed mass and lowest relative growth rate. After one growing season, height was positively correlated (r2 > 0.6) with seed mass in 15 populations. To check the duration of seed mass effects, height growth of 1- to 7-year-old field experiments established with the same seed lots were compared. Seed mass effects on height were strongest for 1-year-old seedlings and declined or disappeared by the age of 5–7 years among central and southern populations, but remained stable over that time in northern populations.
