The growth of unmowed part of a clone did not affected by removing ways in ramet level. But the leave number per tiller was higher in treatments 2, 3, 4 and 7 at 2 months after cutting in tiller level.

在分株层次上，不论刈割方式如何都没有影响无性系未刈割部分构件的生长发育；在分蘖层次上，去除量较少的处理（2，3，4，7）中未刈割部分每分蘖叶数至刈割后2个月时增加较为显著。

Taking root suckers of Hippophae rhamnoides artificial population as the research object, based on the field investigation of produced number of clones, space distribution and growth condition, basic characteristics of ramet and relationship of environmental factors and root suckers were studied systematically in different habitats in Zhifanggou hilly-gully regions.

The difference, relative variation of modular number and mass and their frequency distribution were analyzed between treatments, and within and among structural levels of genet, ramet and tiller in grazing experiment.

在放牧实验中，分别以矮嵩草源株、分株和分蘖层次为单位，对其构件单元的数量和生物量、变异系数、频率分布在处理间的差异和相对变异性进行分析；在模拟放牧实验中，分别就无性系内刈割和未刈割部分从这3个层次上比较了构件数量和生物量在处理间的差异和相对变异性，所得结果如下

Under light, middle and heavy degradation, with the increase of degradation, the vegetative ramet capacity of the clones increased, while their reproductive ramet capacity decreased. A typical landscape of "black soil beach" appeared in grassland with extreme degradation; the growth of the clones was in a lowest level.

在轻度、中度和重度退化程度下，随着退化程度的增加，高山嵩草无性系营养分株能力加强，生殖分株能力减弱；极度退化的草地已呈现典型的&黑土滩&景观，高山嵩草的克隆生长维持在最低水平。

The effects of enhanced UV-B radiation on plant height and stem diameter of 10 wild sugarcane (Saccharum spontaneum L.) clones for 3 consecutive years under field condition was investigated.

wild Sugarcane； stem diameter ；研究了大田栽培和自然光条件下，连续3年模拟紫外辐射(UV-B，280~315nm)增加对10个割手密无性系伸长期株高和茎径的影响。

The eliminate efficiency, uptake and accumulation of Salix matsudana to 2,4-DCP in water solution were studied.

对4个旱柳无性系8，10，18和22号进行了水培试验，研究了96 h后旱柳对水中2，4-二氯苯酚（2，4-DCP）的去除和吸收积累能力。

Through 7 years study, the variation regulation and model of white poplar were known well, and 3 best seed sources and30 best clones were screened, making the genetic gain more than 22~28 percent, The results presented here provide a scientific foundation for silvicultural division.

经过7年的研究，摸清了毛白杨的变异规律及模式，筛选出3个种源，30个优良无性系，遗传增益达22%~28%，为造林区划提供了科学依据。

After research on the kinds of culture media, various content of hermone, ultraviolet irridation, temperature and intensity of light in the culture, the callus clone with higher content of flavonoids and ginkgolides of Ginkgo biloba spiraster screened using photometer and HPLC combined.

通过对培养基种类、多种不同浓度的激素组合、紫外线照射、培养过程的温度和光照等条件的研究，采用分光光度法和HPLC法相结合的方法筛选出了银杏黄酮和萜内酯含量都较高的银杏幼叶愈伤组织无性系。

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.
