As a result, better results could be achieved in high yielding gutta-percha clone selection right conducted in low-yield year.

在结果小年时进行高产胶优良无性系的选择具有更好效果。

The results showed that there were intraspecific differences in plant height and stem diameter of tolerant clones, and plant height and stem diameter of sensitive clones decreased significantly.

结果表明：(1)割手密耐性无性系株高和茎径对UV-B辐射响应具有明显的差异；敏感无性系的株高和茎径显著或极显著的下降。

Study on genetic variation of seed bearing property at the first clonal Cupressus funebris seed orchard by 75 ramets of 15 clones demonstrated that seed bearing capacity had significant difference among clones, but had high repetition ratio.

利用柏木一代无性系种子园中15个无性系75个分株材料，研究无性系结实性状的遗传变异规律。结果发现，不同无性系的结实能力差异巨大，其无性系重复力较高。

By the method of randomly digging up whole ramet tuft while maintaining natural integrity, large samples of Cynodon dactylon clones were collected from a grape orchard abandoned for 2 years without any management in the Yili River Valley Plain of Xinjiang, aimed to quantitatively analyze the growth patterns of their modules.

采用随机挖掘整个无性系的方法，在新疆伊犁河谷平原2年无人工管理的葡萄园撂荒地，对狗牙根无性系进行了大样本取样，定量分析了构件生长的规律。

All the 16 clones remained from tube seedlings of Dendrocalamus latiflorus from 3-year cultivation on medium in a high concentration of BA ocoue in flowering phenomenon,and their flowering timing, earlier or later, are correlated with their viabilities, i.

麻竹试管苗经3年在高浓度BA的培养基中培养，保存下来的16个无性系都出现开花现象，开花迟早跟无性系的繁芽能力有关，繁芽能力强的无性系较早开花，繁芽能力弱的无性系较迟开花。

Various clones families could be propagated commercially without having been clonally tested.

在这些家系中不同无性系被大量地繁殖，也没有进行无性系的测定。

The variation coefficients of most traits are greater in half-sib families than that in clones except for several branch traits.The average height of clones is nearly two meters higher than that of half-sib families, and the average volume of clones is 1.16 times about that of half-brethren families.

除枝下高、侧枝粗、分枝角、冠幅等几个分枝性状在无性系间的变异系数大于在半同胞家系间的变异系数外，其余性状均小于在半同胞家系间的变异系数。20个无性系的总平均树高、胸径和材积高于18个半同胞家系的平均值，其中，树高和材积显然高于半同胞家系的树高和材积，平均树高高出近2米，平均材积高出16.1%。

The twig production of different clones is different, from 5.5 twigs per month to 14.8 twigs per month. The rooting rate, root number and root length change regularly as the concentration of IBA goes up from 0.05 to 2.00 mg/L. At the concentration of 0.05 mg/L ppm IBA, rooting rate and root length are the highest. Cutting substrate also has eminent effect on rooting rate and survival rate, 50% peat plus 50% sub-top soil is the best substrate. The survival rate differs greatly among clones, from 56.7% to 90.0%. Rooting rate and survival rate change regularly as season changes. The rooting rate of May and June is middle, that of July and August is high and that of September and October drops rapidly. The survival rate is low in May, September and October and high in June, July and August.

结果表明：不同无性系的萌条数量有显著差异，高的达14.8条／月，低的5.5条／月，平均9.1条／月，从0.05~2.00 mg/L，随着IBA浓度的提离，生根率、根条数、总根长等生根指标均呈现有规律的变化；综合考虑各种生根指标，以IBA0.05 mg/L为最佳生根激素处理，扦插介质对柚木插穗生根有显著的影响，以泥炭土＋黄心土按1：1混合为最佳扦插介质；不同无性系的扦插成活率不同，从56.7%至90.0%，变动幅度大，随扦插季节变化，生根率和成活率均呈现有规律的变化，5~6月份的生根率中等，7~8月最高，9~10月份迅速下降，成活率随季节的变化也是两头低、中间高，6~8月的成活率最高，大于93%。

A systematic study made in a clonal test forest in Linhai on timber properties of paper pulpwood of 20 new aigeiros clones of southern type shows that the fiber length in the trunk of these new clones gradually increases from the top to bottom,the fiber of the branches in the upper part of the canopy being shorter than that of the branches in the middle or lower part of the canopy

系统研究了来自浙江临海黑杨派南方型新无性系试验林 2 0个无性系的纸浆材主要木材性状。结果表明：黑杨派新无性系树干的纤维长度自上而下逐渐增长，树冠上部枝条的纤维较中、下部枝条为短

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。
