After reviewing the previous dissertation on quantitative characteristic trait of recalcitrant seeds, three aspects of quantitative characteristic trait of seed recalcitrant were defined, which are interspecific aspect, intraspecific aspect and individual developmental aspect. And it was supposed that seed recalcitrance was a compound characteristic, with its core composed of desiccation tolerance, low-temperature tolerance and storage tolerance at least, and its concomitants composed of seed size, 1000-seed weight, moisture content at shedding, non-dormancy, systemic taxonomy, ecological and biochemical aspects. Because these core and concomitants are all gradual, transitional and quantitative, it was inferred that seed recalcitrance was a compound quantitative trait.

文章简要概述了从顽拗型种子到顽拗性种子这样一个对顽拗性种子认识提高的过程，在综述了前人关于顽拗性种子数量性状特征论述的基础上，把种子顽拗性的数量性状特征划分为种间、种内和个体发育三个层面，提出种子顽拗性是一种复合性状，其核心至少包括脱水耐性、低温耐性和贮藏耐性三方面的内容，其伴随性状包括种子尺度、千粒重、初始含水量、休眠特性、分类地位、地理分布和保护性物质含量等多方面的内容，而且这些核心内容和伴随性状的每一个方面都具有渐变的、过渡的、数量型的特征，从而阐明种子顽拗性是一种复合数量性状。

The Hg could inhibit seed germination of Alisma orientale Juzepcz, no seed germination was observed under the Hg solution in this experiment, the reason needs to be studied in the near future. Atrazine along concentration gradient could stimulate seed germination except the low concentration. The seed germination increases with the increasing atrazine content. When the atrazine concentration reaches 50mg/L, the seed germination reaches its peak.

结果表明：重金属汞对泽泻种子有抑制，未能诱发出芽来，其根源还有待于进一步的研究；有机污染物阿特拉津在一定浓度下却促进了泽泻种子的萌发，除了低浓度的T1处理比CK发芽率低以外，随着浓度的增加，发芽率逐渐升高，当阿特拉津浓度为50mg/L时，为泽泻种子发芽率最大值。

Compared with the seed rain, the quantities of the perfect and geminated seed were less 2.15 seeds m^(-2) and 0.20 seeds m^(-2) respectively, Seed survival rate and the proportion of seed damaged by animals were 13.51% and 45.90%, respectively, which showed that animal damage was the main cause of seed loss.

土壤种子库种子存活率仅13.51%，动物捕食率达45.90%，说明动物的捕食和搬运是福建青冈种子缺失的原因之一。

With the seeds from nine natural Cyclocarya paliurus populations as test materials, their phenotypic traits, including 1000-seed weight, seed size, seed diameter, seed thickness, and seed diameter/thickness ratio, were investigated, and the phenotypic diversity among and within the populations were studied by the methods of ANOVA analysis, hierarchical cluster analysis, and correlation analysis.

China introduced TQM at the end of 1970s to improve the quality of its industry product but did not make enough progress because the project was impelled by the administration. Since the year of 2000s, monopoly in Chinese seed industry has been broken down and the market is growing rapidly, seed company are facing serious competition both from the inner and the outer so it is in urgent need of improving seed quality and competitive power. Under such conditions, this paper made a study on the feasibility of improving the seed quality and management level of Chinese seed industry by introducing TQM, and hope the research conclusion will be useful to the development of Chinese seed industry.

中国在七十年代末期也开始引入TQM来改善我们的工业产品品质，但是在行政力量推动下的质量运动最后大多无疾而终，效果大打折扣。2000年以来，中国种子行业行政垄断被打破，市场化进程加快，种子公司面临着来自国内外激烈的竞争，亟须提高种子质量，提高自己的竞争力，在这种情况下，笔者对中国种业引入TQM来提升种子质量和管理水平的可行性进行了探讨和研究，希望本文的结论对中国种业的发展有一定的参考意义。
