Abstract

The characters studied were fresh and dry weights, and water contents in root, stem and full (root+stem) of two-year stone pine (Pinus pinea L.) seedlings. Variation, clonal repeatability (-broad sense heritability) and correlations between the characters were estimated. The averages of seedling fresh and dry weights were 10.4 and 4.9 g, respectively. The average water content was higher in stem (51.0%) than that of root (40.3%), while there were large differences within clone and among clones for the water content. The coefficient of variation of the water content among clones was higher than within clones. Clonal repeatability was mostly more than 0.7 for the characters. It was the lowest for dry weight of root (0.64), while the highest for water content in full seedling (0.90). There were generally positive and significant correlations among the characters. The results of the study were discussed based on global warming for new plantations. © by PSP.
