陈山红心杉材性变异及其基因资源利用的研究

比较分析了安福种源（陈山红心杉）同全国公选5个优良杉木种源（广西融水，贵州锦屏，湖南会同，福建建瓯，江西铜鼓）的木材材性，得出：在木材的纤维长度，晚材率，基本密度三方面，陈山红心杉与其它5个优良种源无差异，材性优良，木材的红心比率在6个种源间差异显著，其中以陈山红心杉心比率最大，红心比率变异系数最小，研究了陈山红心杉材性遗传变异规律，认为安福陈山红心杉引种外地不会导致材性变异，可在杉木主要区推广应用，此外，在陈山红心杉基因资源利用上，开展了应用研究和探讨。

Study on Variability of Timber Characters and Gene Resources Utilization for Chenshan Red heare Chinese Fir

Through comparison of timber characters between Chenshan red heart Chinese fir and other five provenances which were considered to be the suprior,the results showed that there is no difference in the fields of fiber length,late timber rate,and basic density in the comparison.The timber characters of Chenshan red heart Chinese fir is good,but the red heart rate is the biggest and red heart variability is the smalest.Based on the analysis of genetic variability regularity of Chenshan red heart Chinese fir,the authors think that introduction will not result of timber characters variability,it is worth of extension to some chief Chinese fir base.And more,this paper also dealed with the genetic resources utilization.
