简介：光洁特点印射的继承分析和基因用在青春期的米饭材料之间的十字被进行Chuanxiang29B(混合米饭的一根芳香的精英维护者线)，和二光洁米饭材料，Lemont和R2(R2是混合米饭的一根新restorer线)。从二个十字的所有F1植物有青春期的叶子，证实在Chuanxiang29B的短柔毛特点在光洁特点上是主导的。在F2个人，分离比率三对一光洁植物青春期建议单个光洁基因在Lemont和R2是在场的。用bulkedsegregant分析，简单顺序重复标记的连接分析证明光洁基因，gl-1，分别地与染色体5上的0.19和0.92厘米的基因距离是由GL311和GL8的flanked。

简介：生物资源和营养素(N，P，K，Ca，Mg)存货在各种各样未葬树部件(stemwood，stembark，树枝和叶子)在东北中国在纯Larixolgensis种植园(20，35，53和69岁)的一个年龄序列被确定。结果证明未葬在各种各样的树部件的生物资源分配在stemwood(62%83%)的顺序，树枝(9%21%)，stembark(7%11%)和为所有看台的叶子(1%6%)。到总数的stemwood生物资源的比例未葬而另外的树部件的从20～53岁与看台年龄一致地减少了，但是与看台保持相对不变，增加的生物资源从53和69岁变老。在各种各样的树部件的滋养的分配通常跟随了象生物资源分配的一样的模式(即stemwood>树枝>stembark>叶子)。在到总数的叶子的滋养的存货的比例未葬滋养的存货与增加看台年龄一致地减少了，当那与看台在stemwood增加了时，从20～53岁，但是然后的年龄从53～69岁减少了。为看台的滋养的移动的率在不同记载的计划下面在不同看台年龄被估计，当旋转长度仅仅被弄短到由茎的收获的20年时，证明滋养的移动的率将是未改变的，但是极大地由总数的收获增加了未葬生物资源。滋养的移动的率将是为由起的所有元素的可观的减小，特别为Ca。
