It could preferably defend seedlings against damping-off and Rhizoctonia rot in seedling stage, wilt disease and anthracnose in mature phase and increase field. After application in cowpea, Fenle Nutritious Seed Coating for beans and ZSB bean seed-coat agent (1:40 for ratio of the chemical to seeds) were selected, which increased emergence rate and improved seedling growth.

在豇豆种子上包衣应用后，筛选出效果较好的丰乐营养豆类包衣剂（药种比为1：40）和ZSB菜豆包衣剂（药种比为1：40），提高了豇豆种子的出苗率，促进了幼苗的生长，同时种衣剂对豇豆种子本身所带的炭疽病病菌和土传的猝倒病、枯萎病均有显著的防效，从而一定程度上提高了豇豆的产量。

Seed explants of Eleutherococcus senticosus produced somatic embryos directly ongrowth regulator-free medium. The results were showed that use low temperature stressmethod to relieve the Eleutherococcus senticosus seed conformation dormancy andphysiological dormancy, to induce seed germinate. Proliferation of Eleutherococcus senticosussomatic embryo without any plant growth regulathors was better in liquid medium containing1/3MS+sucrose 3%, and better in solid medium containing 1/3MS+sucrose 1%.Eleutherococcus senticosus secondary embryo was stick to matrix through espial of cytology.Eleutherococcus senticosus somatic embryo was cultivated some times to form immature frondin liquid medium, then transfer into solid medium to form full plant. The experiment wasindicated that much more Eleutherococcus senticosus immature frond can be cultured inbioreactor, so large-scale production in bioreactor culture can be done.

研究结果表明：低温胁迫处理刺五加种子可以打破种子的形态休眠和生理休眠，促使种子发芽：在不添加任何植物激素的培养基中诱导刺五加体胚形成，其中，1／3MS+3％蔗糖的培养基搭配有利于液体培养的刺五加体胚增值，1／3MS+1.0％蔗糖的培养基搭配有利于固体培养的刺五加体胚增值；在进行体细胞胚增殖时，体细胞胚继代三周后表面开始形成很多次生胚，对刺五加次生胚进行细胞学观察，发现刺五加次生胚与母体只是粘贴在一起；刺五加体胚需在液体培养基中培养一段时间形成幼植物体，实验表明可以通过生物反应器培养大量的刺五加幼植物体，然后转入固体培养基中形成完整植株，因此可以通过生物反应器培养进行规模化生产。

According to the American Journal of Botany, a 14th-century lotus seed was recovered from an ancient lake bed in China, becoming the oldest germinated seed on record. Nelumbo nucifera

而且，种子的生命力很强，根据美国植物学杂志，"中国一颗十四世纪的荷花种子已经重新获得生命力来自远古的湖底，适当的这古老的种子发芽在报告上"。

Moreover, Seed dispersal also relies on animal and waterpower, which make seeds spread far distance, at the same time, the penetration of seed capsule can be improved by the dam age of animal's digestive system, so it can promote the seed germination.

此外，还有动物散布和水力作用的散布，使种子能传播较远的距离，同时种子被采食后，通过消化道的磨损使种皮的通透性提高，促进了种子的萌发。

Under consecutive irradiance and 14 h / 10 h light-darkness cycle, the effects of different gradients of irradiance on seed germination of Shorea wantianshuea, an endangered and rare species of dipterocarpaceae in Xishuangbanna, Yunnan Province, were studied. Also, the effects of different temperatures on seed germination and storage were examined. Neither consecutive irradiance treatments nor periodic ones could improve the germination percentage.

在实验室内人工气候箱控制的条件下，研究了我国重要珍稀濒危植物望天树 Shorea wantianshuea，龙脑香科(Dipterocarpaceae 种子萌发对持续光照、14小时光照/ 10小时黑暗周期性光照的反应；同时研究了望天树种子的萌发对不同温度的反应和低温贮藏对种子活力的影响。

Raffinose family oligosaccharides are among the most widespread low_molecu lar_mass α_galactosides in seeds, mainly includes raffinose, stachyose, verbascose.

许多植物正常性种子的发育伴随着棉子糖半乳糖苷系列寡糖的累积，这些糖的累积已被认为在种子脱水耐性获得、种子活力、糖的运输及植物的抗冷驯化等过程

To investigate the relationship between the tolerance to dehydration and superoxide dismutases in Pachira macrocarpa, fresh mature seeds were pretreated with a 12 h DDTC and subjected to 3~20 h desiccation silica gel at 25℃. The results showed that 20 mmolL^(-1) diethyldithiocarbamate treatment inhibited efficiently SOD and SOD activity in seeds and reduced tolerance of seeds to water deficit, which was evidenced with increases in electrical conductivities and malondialchehy of the seeds, and a rapid decrease of the seed vigor during desiccation.

以探讨马拉巴栗种子脱水耐性与其超氧化物歧化酶之间的关联为目的，选用新鲜的成熟马拉巴栗种子，用二乙基二硫代氨基甲酸钠（DDTC， SOD抑制剂）进行12h预处理后，在25℃下进行3~20h的硅胶快速脱水处理，观察种子的萌发率和生理指标的变化。

Therefore, this experiment that 75 mg / L concentration of the most appropriate for future experiments in the screening of the large concentration of rye grass seed, can be eliminated with this concentration of poor resistance to many of the seeds and improve the quality of ryegrass seed plants can enhance fertility.

所以，本实验的认为75mg/L的浓度最适宜作为今后实验中筛选黑麦草种子大的浓度，用此浓度即可淘汰许多抗性差的种子，提高黑麦草种子的质量增强植株可育性。
