The medium of 1/2MS+ 0.4mg/L NAA +0,2mg/L IBA was used for rooting, and the rooting rate was 75%. The origin and development of somatic embryos was observed by histological method. It was found that the somatic embryos of Aesculus hippocastanum L were developed from single cell.

通过组织细胞学方法研究体细胞胚的起源与发生部位，发现欧洲七叶树体细胞胚为单细胞起源，外植体的表面及内部都可以发生体细胞胚。

In this study, we investigated the phylogenetic relationships of Chinese Apiaceae subfamily Apioideae, while ascertain or confirm the phylogenetic placements of all ten Chinese endemic genera by means of morphology, cytology and molecular systematics.

本研究综合形态学、细胞学和分子系统学等多学科的手段和方法，以中国芹亚科为重点研究对象，集中探讨中国芹亚科类群的系统演化关系同时确立中国伞形科10个特有属的系统学位置。

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。

Methods Among 14 cases of DGF, one was diagnosed as renal vein embolism, two as nephrotoxicity caused by CsA, six as acute tubular necrosis and five as acute rejection. The diagnoses were confirmed by clinical presentation, blood creatinine, color Doppler ultrasonography, and fine needle asperation biopsy, etc.

通过对发生DGF的14例患者临床表现、血肌酐、环孢素A血浓度、彩色多普勒超声、移植肾细针穿刺吸抽细胞学检查等分析，诊断移植肾静脉栓塞1例，CsA中毒性肾损害2例，急性肾小管坏死6例，急性排斥反应5例。

Thinopyrum intermedium,one of the relative species of common wheat,is a kind of dominant wheat germplasm resource for the resistance to stripe rust in wheat genetic improvement. With using Chinese spring phlb as recurrent parents and awnless Zhong 4(a partial chromosome of Thinopyrum intermedium)as donor parents,that is backcross selection,the offspring BC_2F_(7～9)were acquired.Cytology check and genome in situ hybridization, were used for the translocation lines and substitution lines detection.

本研究采用常规杂交并辅抗性鉴定等方法，以中国春phlb突变体为轮回亲本，利用无芒中4，转育中间偃麦草的抗条锈性，并通过细胞学和DNA原位杂交检测，鉴定和筛选普通小麦—中间偃麦草的抗条锈病异代换系或易位系。

Cytology reveals cells with clear to lightly basophilic cytoplasm and round or indented nuclei with fine chromatin and indistinct nucleoli.

细胞学分析可见透明至浅染的酸性细胞质和圆形或缩进的细胞核含有正常的染色质和模糊的核仁。

The result showed that the key stage of sterility was the late binucleate stage.2.158 candidate bands generated by cDNA-RAPD (random amplified polymorphic DNA) were recovered from denatured polyacrylamide gel.

主要结果如下： 1、对喷施化学杂交剂BAU9403的农大3159进行细胞学水平观察发现，花粉的发育加快，提早解体，败育发生的关键时期是花粉二核期后期。
