落叶松

This paper analyzes several key factors of the impact on the survival rate of the Larix principis-rupprechtii,and considers that the strong sprout seeds and planting seriously is a key factor of increasing the survival rate.

成活率是检验造林成败的一个关键技术指标，对影响华北落叶松成活率的几大关键因素进行了分析，认为良种壮苗和认真栽植是提高造林成活率的关键因素。

The increment of height Larix leptolepis was affected mainly by precipitation of last summer, and volume increment was affected mainly by the precipitation of last summer and 10 cm groud temperature of last spring.

由此可以综合得出对日本落叶松生长量影响较大的气象因子是上年夏季的降水量和春季10cm地温。

The present study has built a solid foundation for identification, characterization, gene cloning and standardization of relation proteins in the embryogenic tissues of Larix leptolepis.

从本研究所获得的具高分辨率日本落叶松胚性愈伤组织蛋白质图谱，将为今后与愈伤组织的分化能力相关的蛋白质的检测、分离和基因克隆，以及胚性能力相关蛋白标准化的制定等提供参考。

In this study, six development periods duiring somatic embryo maturation of embryogenic cell line Y35 of Larix leptolepis×L.

本研究以杂种落叶松Larix leptolepis×L。

The innorate points is that climatic factors that affect the growth of Larix leptolepis in west -ern Henan province are systematically studied by step-by-step regression and grey relation analysis based on data from 15 analytical stem of Larix leptolepis and 10 climatic factors, and the theoretical basis for forest nursery and

对日本落叶松影响的气象因子进行如此系统的定量研究国内未见报道。

The order of the effect of the climatic factors on the increment of Larix leptolepis was The precipitation of last summer, 10 cm groud temperature of Spring, the relative humidity from September to October in last year,≥10℃ accumulative air temperature ,10 cm groud temperature from September to October in last year, sunligh hours, relative moisruer of Februry, precipitation of November, the average temperature from April to May last year, the average temperature of last Winter.

按气象因子在回归方程中出现的次数频率将气象因子对日本落叶松生长量影响程度排序为：上年6～7月降水量、当年3～4月10cm地温、上年9～10月相对湿度、≥10℃积温、上年9～10月10cm地温、年光照时数、当年2月平均相对湿度、上年11月降水量、上年4～5月平均气温、上年11月～当年1月平均气温。

The order of the effect of the climatic factors on the increment of Larix leptolepis was the relative humidity from September to October in last year, precipitation of November, relative moistuer of Februry, The precipitation of last summer, sunligh hours, 10 cm groud temperature of Spring,≥10℃ accumulative air temperature, the average temperature from April to May last year, the average temperature of last Winter, 10 cm groud temperature from September to October in last year.

按最大关联度出现的次数频率将气象因子对日本落叶松生长量影响程度排序为：上年9～10月相对湿度、上年11月降水量、当年2月平均相对湿度、上年6～7月降水量、年光照时数、当年3～4月10cm地温、≥10℃积温、上年4～5月平均气温、上年11月～当年1月平均气温或、上年9～10月10cm地温。

They left it to wind through a slashy cut, leading the horses through brittle branchwood, Jack, the same eagle feather in his old hat, lifting his head in the heated noon to take the air scented with resinous lodgepole, the dry needle duff and hot rock, bitter juniper crushed beneath the horses' hooves.

他们就不走正道了，带着马穿树丛。杰克，头上戴着顶插着那片鹰羽的旧帽，仰头呼吸空气，空气中充满各种味道，灌木树脂的，干的落叶松的，烫的岩石的，还有马蹄下黏的踩碎的苦松针的。

In the lever of isozyme,10 species of Melampsora larici-populina are divided into four groups:the first includes Nm ,GL, H159,CJQ and ZST ;the second is Qh and Bqy, the third is Scb and Ts, Tt is included in the forth group.

在同功酶水平上落叶松-杨栅锈菌主要分为以下四大类：Nm、GL、H159，CJQ和ZST为第一类； Qh和Bqy为第二类；Scb和Ts为第三类；Tt为第四类。

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。
