The results showed that the non-embryonic callus were cultured on the MS medium contained 4.0 mg · L-1 2,4-D and 0.5 mg · L-1 6-BA, embryogenic cells appeared in it. Then the single embryogenic cells formed a proembryo composed of many cells through cell division.

结果表明，非胚性愈伤组织转入到MS + 4.0 mg · L-1 2，4-D + 0.5 mg · L-1 6-BA培养基培养后，愈伤组织中先出现一些胚性细胞；然后单个胚性细胞分裂形成一个由多细胞组成的原胚。

The increase of the area of the compound eyes in Cherax quadricarinatus is mainly caused by the increase of both the number and the area of the ommatidia.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
