Five Years Performance of New Introduced Salt Tolerant Hybrid Poplar clones (Mofid and P. x albaeuphratica) In Iran (West Azar-Bayjan)

摘要

In order to introduce new hybrids poplar clones ("Mofide" and P. x albaeuphratica) for commercial wood production in different part of country, ecological range of productivity have to be determined. Therefore, adaptability of two hybrid clones "Mofide" and its reciprocal crosses hybrid (P. X albaeuphratica), along with Populus alba L. as local clone (Kaboodeh) were tested in Rasol Abad Salty-soil Research station during 2004-2009. The experiment was conducted through randomized complete block design (RCBD). Twenty five individual cuttings of three clones (two hybrids and one local clone) planted in 100 square m as an experimental plot at spacing (2 x 2 m distance) and replicated three. Analyses of collected data have been done based on quantities and qualitative characters during five years. The results indicated that there were highly significant differences between clones at the 0.01 level. Populus euphratica Oliv. x P. alba L. hybrid (Mofid) showed highest diameter at breast height (11.30 cm), and total height (10 m) than the others two. Low level of breast diameter height (4.15 cm) and total height (5.5 m) were observed for Populus alba L. (Kaboodeh) clone as a local poplar clone.
