发芽率

Seeds were germinated at eleven salinities (0,20,40,60,80,100,120,140,160,180,200 m mol/L NaCl) and germination percentage, rate of germination, as well as seedling growth were measured to detect the differences amang three cultivarscline.

在0，20，40，60，80，100，120，140，160，180，200m mol/L浓度NaCl胁迫条件下，研究了发芽率、发芽指数，并比较分析了胚根、胚轴生长状况。

Amaranthus retroflexux L. and Trifolium repens L.. The result showed that three different extracts inhibited the germination rate of seeds and inhibited the growth of seeding and young root. The experiment showed that White clover existed obvious allelopathy and autotoxidity effect.

结果表明，地上部分水浸液、挥发物和根系分泌物显著抑制了反枝苋、苘麻和自身种子的发芽率，三部分提取物显著的抑制了苘麻、稗草和自身种子在萌发过程中芽长和根长的生长；试验表明白三叶草存在明显的化感作用且有一定的自毒作用。

The germination ratio of Aralia elata seeds dry-stored under ordinary condition can be over 50% when they were treated with different pregermination and soaking methods.

本实验采用不同的催芽方法及不同的浸种时间，使干藏1年的龙牙楤木种子发芽率仍可在50％以上。

This study investigated the effects of different concentration GA3 on Aralia continentalis Kitagwa seed germination under fluctuating temperature (25℃/5℃), temporal changes in α-amylase activity at 150mgL^(-1) GA3 during stratification were determined.

在变温层积(25℃/5℃)的基础上，采用不同浓度GA3处理长白楤木种子，测定种子发芽率和发芽势，测定150mgL^(-1) GA3处理的种子－α淀粉酶活性的变化。

The best seeding quantity is 0.65 g/m2 when the 1000-seed weight, pure rate and germination rate of the Aralia elata seeds was 1.2 g, 95% and 70% respectively.

若按照龙牙楤木种子的品质指标(千粒重为1.2g，净度为95％，发芽率为70％)来衡量，当成苗率保证在70％时，最佳播种量为0.65g／m~2。

The results showed that more effective measures are the blading pierced seeds and sulfuric acid soaking seeds 50min.

结果表明：刀片破皮和98%浓硫酸浸种50min效果较好，处理后种子发芽率分别达到98.0%和98.7%。

The optimum temperature of Bromus rigidus Roth was 20℃ if the germination percentage, germination index and the value of vigor index were all considered.

综合发芽率、发芽指数和活力指数最后确定硬雀麦的最适发芽温度为20℃。

In seeds of Bupleurum chinese, some problems exist such as low germination rate and high inembryonate rate. To investigate the reasons for these problems, the phases of inflorescence differentiation and the variation of differentiation processes between inflorescences at different positions were studied.

为了了解造成北柴胡种子发芽率低、无胚率高等种子质量问题的原因，本文对北柴胡花序分化进程的各个时期以及不同位置花序分化进程的差异进行了研究。

The cadmium stress was set up by 5 concn. treatments at 0, 0.5, 5.0、10.0, 50.0 mg/L to soak D. caryophyllus seeds and fresh leaves resp., the seed germination energy, leaf chlorophyll and isozyme were determined. The low concn.

方法］镉胁迫设5个处理(0、0.5、5.0、10.0、50.0mg/L)，对石竹种子浸泡后测定其发芽率；对新鲜石竹浸泡后测定其叶绿素含量和同工酶。

Seeds of congeneric crop but different varietal type and planting season vary very much in percentage of germination .

同一种作物不同品种类型和种植季节发芽率变化差异显著。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
