孢原

We used potassium antimonate to precipitate exchangeable cellular Ca(superscript 2+)-calcium that is sufficiently loosely bound to combine with antimonite, to investigate the feature of calcium distribution during anther development of Lycium barbarurn L.

摘要在枸杞花药发育过程中，用焦锑酸钾沉淀的钙颗粒显示出了一个与花药发育事件有关的分布特征：在孢原细胞时期的花药中钙颗粒很少。你知道它的英文吗？· a。过于纤弱的，过于微妙的

Archesporium The single cell or group of plant cells in the sporophyte from which spore mother cells may eventually develop in a sporangium.

archesporium 孢原细胞：植物孢子体中的单个细胞或单组细胞。在那里孢子母细胞最终发育为孢子囊。

In the late of April of the second year, male inflorescences unbound and pollinated. When female inflorescences accepted the pollen grains, ovary development was increased in early May. With the development of either of the two ovule, funiculus, integument and nucellus were differentiated. Embryo sac mother cell came into being and the meiosis begins. Then fuctional megaspore developed into matured embryo sac that contain eight nucleuses. In the end of May, double fertilization generated.

次年，4月下旬，雄花序解螺旋散粉，雌花序开花授粉；5月上旬，雌花序授粉后，迅速增长，子房膨大，两个胚珠分化出珠柄、珠被和珠心，珠心中产生孢原细胞；5月中下旬，大孢子母细胞形成并减数分裂，功能性大孢子形成成熟的八核胚囊；5月底，发生双受精。

The results show that the normal process begins with archesporial cell and undergoes stages of primary and secondary sporogenous cell,microspore mother cell,dyad,tetrad,central nucleus microspore,vacuolated microspore,mature microspore,twocell pollen and threecell mature pollen.

对平流层辐射处理SP3谷子和对照CK3谷子雄性细胞发育的研究表明，雄性细胞正常发育过程从孢原细胞开始，经初生造孢细胞、次生造孢细胞、小孢子母细胞、二分体、四分体和单核小孢子中央期、单核小孢子液泡期、单核小孢子成熟期直到二细胞花粉、三细胞成熟花粉结束。

The reproductive development process of birch was described as follows: Male inflorescences extended from apical bud in early June. In later June, stamen primodium was differentiated in the bract of male inflorescence and the differentiation of bract was generated in female inflorescence. During July, anther layers and archesporial cell were differentiated in anther, then archesporial cell developed into mother microspore cell. Pistil primodium came into being at the same time. In early part of August the meiosis of mother microspore cell started. In later August, mono-nucleus microspore was formed. After September, both male inflorescence and female inflorescence were dormant.

白桦的生殖生长发育过程如下：6月初，雄花序从顶芽中生长出来。6月中下旬，雄花序苞片上分化出雄蕊原基，雌花序分化出苞片。7月，雄花花药分化出花药壁和孢原细胞，孢原细胞演化为小孢子母细胞，雌花序苞腋处分化出雌蕊原基；8月中上旬，小孢子母细胞减数分裂，8月下旬形成单核小孢子；9月后雄花序以单核小孢子状念越冬，雌花序以雌蕊原基状念越冬。

Under normal temperature, anthers of not fertility restoration stopped developing in the stage of archesporical cell; 1-2 comers of a few anther could differentiate and form archesporical cell, sporogenous cells and microspore mother cell, but microspore mother cell disintegrated on the first meiotic division.

常温下，未发生育性恢复的花药在孢原细胞期就停止发育；少数花药1~2个角隅处可分化形成孢原细胞，造孢细胞，花粉母细胞，但花粉母细胞在减数分裂的第一次分裂时解体。

Under low temperature condition, fertility restoring, anther developing normally, the tetrads formed after archesporical cell, sporogenous cells and microspore mother cell. Subsequently, microspores were free from the tetrad of fertile anther and formed mature pollen grains, tapetumof the fertile anthers began to disintegrate and disappear at last.

在低温处理条件下，育性恢复，花药发育正常，经过孢原细胞期、造孢细胞期、花粉母细胞期后，可以顺利形成四分体，可育花药的四分体可以释放出小孢子并发育为成熟的花粉粒，同时绒毡层细胞开始解体，最后消失。

When the concentration of NaCl was further increased to 8%, the cells of P. chrysosporium were deformed and plasma was completely vacuolated, indicative of a severe damage of P. chrysosporium. The DNA similarity was reduced to blow 67% and the rate of abnormal cells was increased to about 90%. The cells of P. chrysosporium thus essentially lost their original structure and function.

chrysosporium的结构与功能产生不良影响；NaCl浓度≥8%可对黄孢原毛平革菌产生严重损伤，细胞变形严重，空泡化，DNA相似度降至67%以下，异常细胞量约90%，表明此浓度范围可使黄孢原毛平革菌基本丧失了原有的结构与功能。

The biodegrading effect of 2,4-Dichlorophenol from aqueous solution by immobilized Phanerochaete chrysosporium was studied and the feasibility of using immobilized Phanerochaete chrysosporium to treat the chlorophenols-contamination water was investigated.

研究固定化黄孢原毛平革菌对水溶液中2， 4-二氯酚(2， 4-DCP)的降解效果，探讨固定化黄孢原毛平革菌处理水溶液中氯酚类污染物的可行性。

Selective abortion stage of the stamen was primarily manifested in the stage of archesportial cell formation through anatomic observation for male sterile flower and male fertile flower. There was no archesportial cell development or anther production and was a male sterile line without anther.

通过对不育系和可育系小花的细胞及形态解剖学观察，初步确定万寿菊雄蕊选择性败育的时期，为花药受阻于花药原基细胞分化期，无孢原细胞形成和药室分化，属于无花粉囊型不育系。

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。
