They are continually come up to the maximum with direction of from marrow to cortices, and then fixed.

以上分析表明，种源内毛白杨无性系间木材品质性状也受强的遗传控制。

The present thesis is intended to approach several aspects on the mechanism of plant somaclonal variation by cytological methods.

本论文拟从细胞学的角度探讨植物体细胞无性系变异发生机理方面的几个根本问题。

The results show that there existlaminal paraheliotropic movement and diaheliotropic movement under light stress,whichadjusts absorption of light energy.

结果表明：自然强光胁迫时，无性系通过叶角的&避光运动&调节对光能的摄取量。

In seed orchards, this is accomplished through the establishment of dilution zones, control of the positioning of orchard clones, plant espacement, etc.

这就是在种子园设立稀释带，控制园内无性系的位置和株行距离。

In seed orchard s, this is accomplished through the establishment of dilution zones, control of the positioning of orchard clones, plant espacement, etc

这就是在种子园设立稀释带，控制园内无性系的位置和株行距离。

On the basis of investigation and measurement by sampling of the alone tuft in the blooming stage, characters of growth and production on the clone of Festuca arundinacea in middlemountain conditions in subtropical region of China were quantitatively analysed in this paper.

根据以分蘖丛为单位的调查与测定，定量分析了亚热带1800m中山立地条件下苇状羊茅无性系的生长与生产特征。

Flagellaria clonal population increases gradually with the growth,and reaches the maximum in August.

蔓委陵菜无性系种群叶柄长度随着生长进程而逐渐增大，8月份达到最高值。

The P. flagellaria clonal population distributing in the Songnen grassland was studied,and we observed the season dynamics of petiole length and the total stolon length as well as pattern of spacer length,compared the numbers of maternal ramets,daughter ramets and single ramets as well as the yearly dynamics of total biomass in 3 years (2003,2005,and 2006). Furthermore,we analyzed the correlation between population quantative character and the community's quantative character.

以松嫩草地羊草草甸内分布的蔓委陵菜无性系种群为研究对象，观测了叶柄长度、匍匐茎总长度的季节动态以及间隔子长度分布格局，比较了3个年份（2003、2005、2006年）的种群母株数、分株数、独立株数和总生物量年间动态，分析了种群数量特征与其所分布的群落的数量特征之间的相关关系。

In the same observation time, the number of maternal ramets and daughter ramets, the total length and the number of stolon and branching intensity of P. flagellaria clone population were higher than P. anserina. But the average length of spacer and stolon of P. anserina were more than P. flagellaria.

在同一观测时期内，单位面积内蔓委陵菜无性系种群的母株数量、分株数量、匍匐茎总长度、匍匐茎条数以及分枝强度均高于鹅绒委陵菜种群；而鹅绒委陵菜的间隔子平均长度、匍匐茎平均长度均大于蔓委陵菜。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
