Stone pine (Pinus cembra L.) provenance experiment in Romania I. Nursery stage at age 6
1997
Blada, I.
The paper reports results of a stone pine (Pinus cembra. L.) provenance study conducted in a 4-replicated complete block design nursery provenance test. At age 6, total height growth, height increment in the 6-th year, diameter atroot-collar and number of buds around the leader bud were statistically analysed. Highly significant (p below 0.001) differences between provenances were noticed for all tested traits. DUNCAN's test suggested a major gap between genetically isolated populations within the natural range of the species. After 6 years of testing, one can not conclude whether the species is characterized by a continuous or a discontinuous distribution pattern. Fast growing and slow growing provenances were found in populations in both the Alps and Carpathians, suggesting that the improvement by selection would be profitable.
