In the gymnosperms the megaspore gives rise to a cell that is termed the embryo sac because of its similarity to the angiosperm structure.

The mature embryo sac fertility, formation and development of embryo sac of 141 accessions of O. rufipogon Griff. collected from the six sampling sites in Gaozhou, Guangdong Province were studied by using the technology of whole-mount stain-clearing confocal laser scanning microscopy.

利用整体染色激光扫描共聚焦显微镜术，对采自广东省高州市6个地点共141个编号的高州普通野生稻的成熟胚囊育性和胚囊形成发育特点等进行研究。

Abnormal phenomena in different periods of embryo sac development, including degeneration of megaspore, embryo sac abnormality during the periods of two to eight nucleate etc., were found in the plants with low seed setting rate.

对一些结实率偏低材料的研究，发现在胚囊发育过程的不同时期存在一些异常现象，包括功能大孢子退化，二至八核胚囊发育异常等。

Polyembryonyoccurs in 〓 and 〓 caryopsis of cross SB-1 X Balilla(Balilla is non-polyembryony),and in 〓 caryopsis ofits reciprocal the polyembryony is observed but not in 〓caropsis.

在正交（SB-1 X 马来红，马来红不具多胚特性）〓及〓颖果中都出现了多胚苗，反交（马来红 X SB-1）的〓颖果未出现多胚苗，但其〓颖果观察到多胚苗，表明SB-1的多胚不是合子裂生产生的，而是胚囊的一种特殊性状。

The result showed that the HA titer of virus in allantoic fluid reached its maximum 1:256~1:512 in the condition that the 9-day chick embryo received 50 times dilution of 1:64 GPMV and cultured for 48~72 h in 37℃.

结果表明将血凝价为1：64的鹅副粘病毒稀释50倍后，接种9日龄鸡胚，37℃培养48~72 h获得的尿囊液血凝价可达1：256~1：512，平均尿囊液量可达9.4 mL/胚。

To understand the degeneration of unfertilized aposporous embryo sac in an aposporous species Pennisetum squamulatum, the central cell in the unfertilized embryo sac was characterized ultrastructurally.

为理解植物无孢子生殖胚囊未受精条件下的退化，对无孢子生殖植物非洲狼尾草未受精成熟胚囊中央细胞退化做了细胞形态学研究。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
