孢原组织

At the reproductive stage, RA68 was expressed in the inflorescence meristem, the tip of rachis branch, spikelet primordia, macrospore sac and pollen grains.

原位杂交分析结果表明：在幼苗期RA68主要在幼芽胚芽鞘的内外层细胞和幼叶原基的表层细胞中表达；转入生殖生长期后，在花序分生组织、枝梗原基顶端、花器官原基、大孢子囊和花粉粒中表达。

Microscopic observation on anther development process of cytoplasmic male sterile line"1815A"showed that its anther development was inhibited at the stage of archesporial cell differentiation.

以1815A不育系对应的保持系1815B作对照，对不育系进行细胞学观察，结果表明：随着花蕾的发育，败育的雄蕊一直处于孢原细胞时期，不能形成花粉囊并产生花粉母细胞，但雌蕊和维管束组织发育正常。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
