Abstract: To select superior families of juvenile Cyclocarya paliurus, seven families of four-year-old C. paliurus were selected as test materials. The variation in growth rate, microfibril angle, basic density and crystallinity were studied. The results indicated that there was a significant difference in diameter at breast height(DBH), microfibril angle, basic density and crystallinity among the seven families. The average DBH ranged from 4.93 to 6.47 cm, while basic intensity and crystallinity were 0.441-0.547 g/cm³ and 37.63%-46.62%, respectively. The microfibril angle ranged from 19.0°to 30.6°, and the value decreased with the age of growth ring increasing. The variance analysis indicated that the variation was mainly from provenances. The DBH showed a weak negative correlation with the basic density, but a highly significant negative correlation with the crystallinity and a significant positive relationship with the microfibril angle, respectively. Furthermore, crystallinity had a highly significant negative correlation with the microfibril angle, but there were no significant correlation among other wood properties. This trial suggested that it may be more effective to select superior families on provenance level.
