种子的

The contraceptive efficacy of Carica papaya seeds after short-term evaluation has been well established. We have examined the safety and mechanism of contraception in rats after long-term treatment with the methanol subfraction of C.

番木瓜种子的短期避孕效果已经确认，本文旨在研究大鼠长期服用番木瓜种子甲醇分馏物避孕的安全性和避孕机制。

They form the first photosynthetic organ in seeds showing epigeal germination, e.g. sunflower but in others they remain underground.

有些种子的子叶在种子萌发后露出土面，进行短期的光合作用，如向日葵，但在另一些植物中子叶仍然在地下。

The inhibitory effect of NaCl on the halophytic seeds decreased with the delay of treatment time, but that on nonhalophytic seeds incresed up to the 8 th day, after then did not incre...

另外 ，在 0 。6MPaNaCl下，随处理时间延长，盐地碱蓬和琐琐种子的α淀粉酶活性不断提高，SOD活性基本不变，但小麦和大麦种子的α淀粉酶活性在处理 8d后接近最大值，SOD活性显著下降。

In germination experiment, illumination had no effect on germination rate. Within certain range, rising temperature may accelerate germination rate of Lepidium apetalum, but had no effect on other species. The vermiculite of different soils also has great effect on seed germination.

萌发实验结果则表明，光照对四种短命植物种子萌发率没有显著影响；在一定范围内温度的升高能够促进独行菜种子的萌发，而温度升高对其它三种短命植物没有显著影响。

Preliminary Tests for Chemical Components of Leucaena leucocephalaLam.

目的采用系统预试法对银合欢种子可能的化学成分进行预实验，初步探索银合欢种子的化学成分。

Guangxi Traditional Chinese Medical University ,Nanning 530001,ChinaAbstract:ObjectiveTo identify the chemical components of Leucaena leucocephala de Wit seeds using comprehensive preliminary tests.

目的采用系统预试法对银合欢种子可能的化学成分进行预实验，初步探索银合欢种子的化学成分。

This indicated that the seeds of Cyclocarya paliurus was relieving dormancy and prepared for germination.

这也预示着，青钱柳种子在不断的打破种子的休眠，为萌发做好准备。

Capsule oblong, trigonous, ca. 5 mm, 3-valved; posterior valve with 1 seed, indehiscent; other 2 valves each with 2 seeds, dehiscent.

蒴果长圆形的，三棱，约5毫米，3瓣裂；后面裂片具1种子，不裂；其他2裂爿每个具2种子的，开裂。

The results show that 0.7% and 1.0% NaCl solutions are appropriate to identify the salt tolerance of alfalfa during geminating period.

结果表明：用0.7%或1.0%NaCl溶液性鉴定较为合理；0.7%NaCl溶液处理苜蓿种子，其幼苗重和幼苗高可作为苜蓿品种耐盐的鉴定指标。0.7%、1.0%NaCl溶液处理下，通过测定第3天和第5天各品种种子的发芽势，可以鉴定耐盐性大小。

The author had done some prepared work about tissue culture of Sinopodophyllum hexandrum Ying, found its seed-coat was a limit of germination but seeds can get a better germination rate after treated by 150mg/L GA3 and being cut at the part of hila.

本文进行了桃儿七组织培养的前期工作，发现桃儿七种皮限制其种子萌发，用150mg/LGA_3处理、在种脐部分剪开一个切口可以大大提高种子的萌发率。

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。
