The viewpoint that seed recalcitrance is a compound quantitative trait is a new and further cognition, which will be a help for studying causes and resolve of seed recalcitrance on species-specific basis.

种子顽拗性的复合数量性状特征的提出及其三个层面的划分，有助于加深对种子顽拗性的认识，并用以指导我们在实践中解决种子顽拗性方面的具体问题。

Hevea brasiliensis seeds belong to the typical recalcitrant seed, and have the typical recalcitrance: Desiccation sensitivity, chilly sensitivity and storage intolerance, therefore, Instant Sowing after Harvest has to be required in the practice, which restricts the development of some practices of Hevea brasiliensis seedling technique.

橡胶树种子属于典型的顽拗性种子，具有典型的顽拗特性：脱水敏感性、低温敏感性、不耐贮藏性，因此，在生产实践中不得不要求橡胶树种子"即采即播"。这限制了橡胶树育苗等相关生产的发展。

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。

我们认为：1土壤种子库拥有大量早期演替阶段的物种；2条件耐受性物种通常缺乏种子库；3退化强烈的影响了条件耐受性物种，而对杂草性物种的影响不大；4土壤种子库对青藏高原高寒草甸的恢复具有重要的贡献。

The seed of Camelina sativa contain 5.67% jelly which envelopes the seed and could absorb 181.31 times water. This might be the main cause that the seeds of Camelina sativa absorb more water in more rapid speed than wheat, which can explain the drought-resistance of Camelina sativa.

亚麻荠种子的外层胶质占种子总重的5.67%，可吸收181.31倍的水分，使种子在最初10min内即可吸收相当于自身重量8倍的水分，浸泡24h后吸水量达到10倍左右；而小麦种子浸泡24h后吸水量只有54.7%，据此认为这可能是亚麻荠种子抗旱性较强的原因。

This paper presents a study of Eucalyptus dunnii tissue culture, using its seeds as explants. The results reveal that MS medium is a suitable basic medium for its seeds to germinate and grow; that MS+KT1.0 mg/L+2, 4-D2.0 mg/L+Homocysteine30mg/L is a good medium to induce its seeds to dedifferentiate directly into callus; that H+6-BA2.0 mg/L+IAA0.2 mg/L is a good medium to make its bud on the seedling reproduce more buds; that MS+6-BA2.0 mg/L+NAA0.2 mg/L is a better medium to induce its root on the seedling into callus; that B5+6-BA2.0 mg/L+2, 4-D0.2 mg/L can induce its under-hypocotyl to differentiate into buds; and that B5+Ad2.0 mg/L+IAA0.2 mg/L can induce its under-hypocotyl into callus to generate normal buds.

According to the year with the best large-seed production, the reasons for empty seeds could be estimated as follows: Seed potential per cone calculated as 2 times the number of fertile ovuliferous scales was about 206 seeds. Percentages of seed losses resulting from pre-and post-pollination ovule abortion, prezygotic factors, embryo degeneration, and efficient seed were 33%, 27%, 39%, and%, respectively.

依据大粒种子产率最高的1年来估测空粒种子产生的因素，可以推估如下：依据每个可孕性鳞片所含2粒种子的鳞片数，潜力种子数约有206粒，再依此值算出受粉前后胚珠败育率、受精前败育率、胚败育率、及有效种子率分别为33%、27%、39%及%。

The results indicated that the lignified seed shell had a negative impact on water permeability of seeds,but it was not the main reason for seed dormancy.

结果表明：(1)美国桂花种子木质化种壳对种子的吸水透性有一定的阻碍作用，但不是引起种子休眠的主要原因；(2)美国桂花种子的胚没有休眠，离体胚在光照培养7 d开始萌动；(3)胚乳被严密包裹的机械作用使胚无法获得萌发所必需的水分和氧气，这可能是导致种子休眠的最主要的原因。

The galactosyl oligosaccharides of raffinose series are widely distributed in seeds of many species and are localized in tissues that remain viable after desiccation, including the embryo and aleurone layer of cereals, cotyledons and axis tissues of legumes and other dicots.

棉子糖半乳糖苷系列寡糖广泛分布在许多种植物种子中，并存在于干燥后仍能保持活力的组织内，如禾谷类种子的胚及糊粉层，豆类及其他双子叶植物的子叶和胚轴组织等。棉子糖半乳糖苷系列寡糖在禾谷类种子的非自溶性中央胚乳中不合成，但存在于蓖麻种子的自溶性胚乳细胞中。

The seed purity of more than one hundred and thirty samples of six maizevarieties was assayed by using the three testing methods: storage proteins electrophoresis,isozyme isoelectric focusing in acrylamide and examination at field plots. Some importantpoints can be concluded from analyses as spearman order rank correlation on the seedpurity data as follows:First, there were deviations of the real performances to those purities obtained from out or in laboratory testing, even from the examination at field plot that is a routine way. Second, the seed globulin and isozyme electrophoresis, both with characteristics of rapid, cost-effective, devoid of environmental effect and speed, showed consistent purity; while the field-testing gave a higher degree of purity on the high side of cost than that in-lab approaches. Third, a good consistent purity was observed in the field plot and seed globulin testing, whereas inconsistency between field-testing and isozyme process. The last point is that seed globulin electrophoresis be a practical method apt to seed purity testing for maize.

并对130多份样品用三种检验方法(盐溶蛋白电泳、同功酶等电聚焦电泳和田间小区)检测的种子纯度数据作排序相关等统计分析，得到如下结果：室内外检测方法都会与种子真实状况有一定差异，田间种植鉴定与真实情况符合性并不一定最好；盐溶蛋白与同功酶等电聚焦这两种方法检测种子纯度所需时间短，成本低，不受外界环境限制，出结果快，二者的结果没有太大差异；田间种植鉴定成本较高，检测的结果普遍偏高；等电聚焦电泳与田间鉴定的一致性年度间存在差异，而盐溶蛋白凝胶电泳法与田间鉴定的一致性较高；种子盐溶蛋白凝胶电泳法较适于鉴定玉米种子纯度。
