种子的

At the same time, we studied population dynamics of seed-eating rodents in the autumn and the following spring. The results showed that, without enclosure protection, most of the seeds were predated due to high predation pressure in the autumn. The emergence rate of seedlings of all the studied species significantly increased under autumn protection, complete protection, and 1-4cm burial under soil covered by litter.

结果表明：秋季鼠类对种子的捕食压力大，使得种子在无保护的情况下很少存活到出苗；而秋季覆网保护和完全保护（覆网一直保留到第二年10月调查时为止）均增加了直播种子的存活和出苗率；将种子埋藏在土壤1-4cm也显著增加直播种了的存活率和出苗率，这与鼠类密度(12%)在秋季显著高于春季(2%)有直接关系。

Spermatophyte Any seed-bearing plant.

种子植物：任何产生种子的植物都是种子植物。

Seed dormancy of M. adenophora was broken by stratifying seeds at alternating temperatures of 30/20℃, 30/15℃, or at a constant temperature of 25℃ for 2mo followed by 5℃ for 3mo, and resulted in rapid germination.

恒春杨梅种子经2个月30/20℃、30/15℃变温层积，或25℃定温层积，接著3涸月5℃低温层积，皆能打破种子的休眠，使种子迅速发芽。

Seeds of Fargesia denudate were treated to accelerated aging and the following indices were measured: seed vigor, T-AOC, activities of anti-oxidative enzymes, contents of MDA, and conductivity, and these indices were also measured on the seeds that differ in size.

为了解缺苞箭竹种子的老化机理和不同大小种子间的差异，对其进行了人工老化处理和大、中、小三组种子的区分，并分别对种子活力，总抗氧化能力，酶活性，丙二醛含量和电导率进行测定。

And Echinochloa crusgalli L. were studied. Both of the aqueous extract from aerial part and root of T. repens inhibited the germination rate of weed seeds, root activity and respiratory rate, and the activities of superoxide dismutase peroxidase and catalase of germinating seeds; enhanced the activity of peroxidase and the content of malondialdehyde.

结果表明，白三叶草地上部分水浸液和根部水浸液显著抑制苘麻和稗草种子的发芽率，降低了杂草种子萌发过程中超氧化物歧化酶，过氧化氢酶的活性，抑制了杂草种子萌发过程中的呼吸速率，根系活力，明显提高了杂草种子过氧化物酶活性和丙二醛的含量。

结果表明，白三叶草地上部分水浸液和根系分泌物显著抑制苘麻和稗草种子的发芽率，降低了杂草种子萌发过程中超氧化物歧化酶、过氧化氢酶的活性，抑制了杂草种子根系活力，显著提高了杂草种子过氧化物酶活性和丙二醛的含量。

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。

On the other hand, the crude extracts of Sapindus mukorossi could not inhibit the seed germination on Pak-choi, but their n-BuOH fractions could retard the germination for 36 h.

至於植物相克作用活性方面，由小白菜种子发芽抑制试验结果得知，无患子木材与果实抽出物各分离部皆无法抑制种子的发芽，但二者之正丁醇分离部均可延缓种子发芽作用36 h。

Conversely the seeds had the longest mean length of incubation time and germination peak value when pollinated every day.4 The planting date had effects on yield and quality of carrot seeds from different seed umbels and poisons of seed disc, also had effects on the growth and development of carrot steckling.

不同授粉时期对种子产量、千粒重、发芽率、发芽势的影响不显著，仅对种子的平均发芽天数、发芽高峰日分别存在显著、极显著影响，且&每日授粉&的种子平均发芽天数及发芽高峰日最长，&隔1日授粉&的种子平均发芽天数及发芽高峰日最短。

The data such as current time, memory total amount, available memory, memory swap file size, available memory swap file size, virtual memory size, available virtual memory size, last random seed and random seed provided by application program have been adopted as random number seed. Thus the problem has been solved efficiently. 2. Solve the self-security integrality problem of common data security architecture.

采用软件方式来实现其随机种子的采集，并采用当前时间、内存总数、可用内存、内存交换文件大小、可用内存交换文件大小、虚拟内存大小、可用虚拟内存大小、上次的随机种子、应用程序提供的随机种子等数据作为随机数种子，有效地解决了这一问题。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
