Twenty eight clones of Alnus cremastogyne were studied on the main characteristics of leaf tissue and on their abilities in water loss controlling.

以28个桤木无性系为研究对象，对其叶片的主要解剖构造特征进行观察、测定与比较，并分析它们在控制水分上的能力。

Eight Alnus cremastogyne clones, which simulated with different concentration of sodium chloride, were measured with four physiological indexes, including SOD activity, MDA content, chlorophyll content and soluble proteins content.

以不同质量分数的盐胁迫对桤木Alnus cremastogyne 8个无性系，在盆栽条件下测定叶片中丙二醛质量摩尔浓度、超氧化物歧化酶活性、可溶性蛋白质量分数和叶绿素质量分数的变化。

The results show that the leaf of Alnus cremastogyne is typical of bifacial leaf, the structural parameters of leaf among clones are very significant difference (P.01), of which the cuticle thickness varies most and the stoma density takes the second place, but cell tense ratio and spongy ratio and vein protuberant degree are comparatively stable.

结果表明，桤木叶为典型的异面叶，各无性系间叶片结构指标均存在极显著差异，其中角质层厚度变异最大，气孔密度次之，而叶片组织结构紧密度、叶片组织结构疏松度和叶脉突起度等比较稳定。

Plant growth was restrained, chlorophyllous content、MDA content and dissolubility protein content in leaves were all reduced, penetrability of cell membrane and dissociative proline content in leaves were increased when plant was threatened by Cadmium.

在Cd胁迫下，金丝柳各无性系植株生长受到抑制；叶绿素质量分数降低；叶片细胞膜透性和游离脯氨酸积累量增加，丙二醛和可溶性蛋白质量分数降低。

This paper deals with the preliminary results on tissue culture and rapid propagation of Cinnamomum camphora.

本文报道应用组织培养育苗技术从樟树家系快速繁殖无性系植株的初步结果。

Somaclonal variation of red-seed watermelon (Citrullus lanatus ssp. vulgaris var. megalasperrnus Lin et Chao) was used in selecting in vitro of the germplasm resources resistant to Fusarium wilt under the stress of Fusarium acid.

以籽用西瓜中信1号红籽瓜不定芽为筛选材料，利用镰刀菌酸(Fusarium acid， FA)为胁迫剂，进行红籽瓜抗枯萎病无性系变异体离体筛选技术和红籽瓜种质资源抗病性鉴定的研究。

Clonal propagation can also give some large gains in a relatively short time.

繁殖无性系也可以在较短期间内提供较大的增益。

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。
