Abstract:

      20 superior poplar clones serve as our research objects. We investigate their tree height, DBH (diameter at breast height) and volume growth property by planting contrast test, comprehensive investigation and stem analysis to get their growth difference. This can provide scientific reference for poplar selection in experimental area. Experimental results show that Zhongzhu 6 is the most suitable clone. 50 Yang, sandy and NL351 exhibit well. I-107 and Zhongluo 759 are not suitable for the test area. Clone 2001 has the highest trunk plumpness while clone 102 has the lowest trunk plumpness.

Key words: populus, clonal variety, tree height, diameter at breast height (DBH), volume of timber, experimental form
