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。

The dormancy reason that the article summed up officinal plant seed and promote the method that cultivates seminal bud, for the gemmiparous experiment of officinal plant seed, optimize grow seedlings, promote quality of high school medicinal material, increase crop to provide reference.

本文综述了药用植物种子的休眠原因和促进种植种子萌发的方法，为药用植物种子的发芽试验，优化育苗，提高中药材质量，增加产量提供参考。

The result makes clear, 37 bright root leach carry fluid to reach 37 water to earth up collect fluid to be offerred to 3 kinds try the inhibition; with seminal bud apparent existence 37 total glucoside are right when density is low 37 seeds bud has little stimulative effect, lift along with chroma, show gemmiparous to 37 seeds inhibition.

结果表明，三七鲜根水浸提液及三七水培收集液对3种供试种子萌发存在明显的抑制功能；三七总苷在浓度低时对三七种子萌发有微小促进功能，随浓度升高，表现出对三七种子发芽的抑制功能。

These are distributed largely in the litter layer, seeds of only 3 extant species were emerged from soil samples. In contrast all of the germinative seeds of the earlier seral species were distributed in the soil.

在种子库中，现存植物产生的种子绝大多数分布于枯枝落叶层，只有少部分（3种）可分布到土壤层，演替前期各阶段产生的种子全部分布在土壤层中。

Studies on treatments of 6 coating pesticides and 5 storage periods with GS Yumai 62 as test meterial indicated that the effect of Cecest 025 on the germinative rate of wheat seed was little, followed by Likexiou Vitavavax 200FF used with normal also had little effect.

通过研究不同药剂和贮藏期对小麦包衣种子发芽率的影响表明：适乐时对小麦包衣种子发芽率影响较小，安全性高，立克秀次之，卫福常量包衣对种子发芽率影响也较小，包衣时应严格按照要求进行。

Exgenous ABA could inhibit germinationof high vigor seeds at low concentration(5ppm).The germinative power,percentage germinationand vigor index were significantly reduced.

外源ABA对高活力种子萌发有显著抑制作用，在低浓度（5ppm）时，种子发芽势、发芽率及活力指数都显著下降；当浓度达40ppm时，则完全抑制种子萌发。

Low concentration of NaCl solution could promote the growth on the shoot of seed germination. The growing length of roots and shoots of two halophytes treated by 100 mmol·L~(-1) NaCl reached the highest and the growing condition on shoots was best. Then some physiological and biochemical parameters including the content of Na~+, K~+, Ca~(2+), proline and plant leaf tissue water potential, the assays of membrane lipid peroxidation and antioxidant enzymes were determined with the two halophytic plants on salinity.

研究工作首先对盐爪爪和盐穗木在种子萌发阶段的耐盐性进行了比较研究，表明盐爪爪和盐穗木都是很耐盐的盐生植物，在种子萌发期，盐穗木比盐爪爪更耐盐；NaCl和等渗的聚乙二醇对种子的萌发都产生抑制作用，且PEG的抑制程度大于等渗的NaCl。

The nutritional composition of six kinds of seed which belong to Labiatae plants have been studied,the results showed:the contents of fatty oil in the seeds was abundant and the contents of unsaturated fatty acid were rich,its unsaturated fatty acid in these kinds of seed oil reached 90% all.the main constituents of fatty acids were:α-Linoleni acid,linolic acid,oleic acid,arachidonic acid palmitic acid and stearic acid.

对六种唇形科植物种子营养成分研究的结果表明：种子含有丰富的脂肪油，其不饱和脂肪酸总量均在 90 %以上。种子油的主要成分为：α亚麻酸、亚油酸、油酸、花生烯酸、棕榈酸和硬脂酸等成分。

The results showed aqueous shoot extracts of Euphorbia maculata could inhibit seed germination speed in all the four species, reduce seed germination rate in Lycopersicon esculentum, Schizonepeta tenuifolia and Capsicum frutescents, and its effects increased with the increase of extracts concentration, while having no effects on seed germination of Edible umaranth.

结果表明，斑地锦浸提液可降低四种蔬菜种子的发芽速率，抑制番茄、辣椒和荆芥的发芽率，并且这种抑制作用随处理浓度的提高而加强，而对苋菜种子的发芽率无显著影响；0.4 g/ml的斑地锦浸提液强烈抑制了四种蔬菜根的生长，却不同程度地促进了辣椒、荆芥和苋菜茎的生长，对根/茎比的影响与对种子发芽率的影响类似。

Result In 5 kinds of chemical treatments, treating Z. macrostachya seeds with 20 % NaOH solution for 20 min and then cleaning the seeds with clear water got the best effect of breaking seed dormancy. By this treatment, the seed germination potential reached 83.5% in 10 d, being 58.2 % higher than CK; reached 85 % in 15 d, being 55 % higher than CK, which was near to the potential germination rate of Z. macrostachya seeds. Compared with CK, the germination duration was obviously shortened.

结果］在5种化学处理中，用浓度20%NaOH溶液处理大穗结缕草种子25min，再用清水清洗，对解除种子休眠效果最佳，10d发芽势达83.5%，比对照高出58.2百分点，15d发芽率达85%，比对照高出55.0百分点，已接近大穗结缕草种子的潜在发芽率，发芽历时比对照明显缩短。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
