摘要

以黑龙江省牡丹江市林口县青山林场1993年种植的落叶松（

Larix

spp.）子代测定林中的3个家系木材为试验对象：日3×兴2 （

Larix kaempferi

3×

L. gmelinii

2）、日5×长77-3（

L. kaempferi

5×

L. olgensis

77-3）和日5×兴9（

L. kaempferi

5×

L. gmelinii

9），采用软X射线成像技术分析生长轮宽度和密度分布特征。结果表明：在生长周期内，各家系生长轮宽度均呈现在生长轮龄前10年迅速降低，10年后趋于稳定的阶段性特征；日3×兴2的年均生长轮宽度最大，生长速率最快。晚材率则表现生长轮龄前10年迅速升高、10年后波动式增加的趋势，日5×长77-3的晚材率稳定性最佳。早材密度在生长初期小幅降低，6~8年显著上升，至15年后再度降低；而晚材平均密度表现为前10年快速增加，10年后保持稳定，使生长轮平均密度呈现先升高后略微降低的动态变化，日3×兴2的晚材密度最高，日5×长77-3的早材密度和生长轮密度的变异系数最低，表现出良好的生长轮间稳定性。研究结果为落叶松优良家系的筛选及定向培育提供理论依据与技术支撑。

Abstract

This study systematically analyzed the growth ring width and density profile of larch wood from three families (

Linkou County

using the soft X-ray imaging technique. During the growth cycle

all families showed rapid decrease in growth ring width during the

first 10 years and then leveled off.

L. kaempferi

3×

L. gmelinii

2 demonstrated the largest mean annual growth ring width

indicating the fastest growth rate. The latewood percentage exhibited an initial rapid increase in the first 10 years and then displayed a fluctuating upward trend.

L. olgensis

77-3 showed the best stability in latewood percentage. The average earlywood density decreased slightly in the initial growth stage

increased significantly from the 6

to the 8

growth ring

and decreased again after the 15

growth ring. The average latewood density increased rapidly in the first 10 growth ring and remained stable thereafter

resulting in the average density of growth rings showing an initial increase followed by a slight decrease.

L. kaempferi

L. gmelinii

2 exhibited the highest latewood density

while

L. kaempferi

L. olgensis

77-3 had the lowest variation coefficients for earlywood and growth ring density

indicating superior stability between growth rings. This research provided theoretical and technical supports for selecting superior families and targeted breeding of larch.
