The efficient embryonic callus system was established by improving culture media and time with callus induced from rice mature embryo scutum.

采用水稻成熟胚的盾片诱导愈伤组织，通过优化培养基组合和调节培养时间，建立了适合水稻遗传转化的胚性愈伤体系，为水稻建立高效的转化体系提供了技术依据。

RESULTS Cochlea, semicircular canal, scutum, internal auditory canal, vertical segment of facial nerve canal were clearly shown in all cases by different slices of MPR images.

结果MPR影像能在不同切面清楚显示耳蜗、半规管、外耳道骨棘、内听道及面神经管垂直段等结构，显示率为100%。

Scutum has a fascinating history.

盾牌座的来历很精彩。

The results showed that the lipase of rice distribute in the plumule and the scutum, not in the endosperm, It consists of several kinds of isoenzyme.

水稻脂解酶主要位于胚芽及盾片部分，它含有数种性质不同的同功酶；

Just like the oxygen isotopic records, the abundance changes of B. scutum indicate the glacial and interglacial cycle and at the same time can be considered as a tool for the stratigraphic classification and correlation.

其丰度变化基本上与氧同位素记录一样，反映了冰期与间冰期旋回，并且可以作为地层划分和对比的工具。
