孢子细胞的

Now the research has made progress.(1) The meiosis stages of megaspore could be discriminated timely through observing the meiosis of microspore under the same environmental conditions, according to the association of female and male buds during development.

1首次提出利用雌、雄花芽发育进程的时序性相关性，以相同生境以及培养条件下的小孢子发育进程为参照，从而相对准确地实现白杨大孢子母细胞减数分裂进程即时判别的技术方法。

Under the same environmental conditions when the meiosis of microspore mother cell develop into tetrads the female buds were dipped duly with colchicine solution, which guaranteed that chromosome doubling of megaspore in white poplar could be accomplished in a short time. So much workload was cut down, and induction efficiency of triploid white poplars was also improved.

当相同生境以及培养条件下的小孢子母细胞减数分裂达到四分体后，适时采用秋水碱溶液对雌花芽进行浸泡处理，可保证白杨大孢子染色体加倍处理能集中于一个较短的时间段内进行，从而大大减轻了工作量，同时提高三倍体诱导效率和效果。

Microspore abortion of H9A occurred in the early uninucleate stage. The tapetum cells were in extreme hypertrophy so that tetrads were extruded to crack and break down and could not form normal uninucleate pollen grains; the abortion type was sporophyte.

结果表明，雄性不育材料H9A的小孢子败育发生在单核前期，由于绒毡层细胞极度膨胀，四分体受挤压后破裂并降解，无法形成正常的单核花粉粒，属于孢子体败育。

In order to reveal the differences among the dimorphic cells, basidiospores, arthrospores and mycelia of Tremellafuciformis were subjected to microscopical observation and electrophoresis analysis.

Methods 1. The mice were divided into control and 3 Ganodermalucidum spores oil groups (at low, moderate and high doses), orally given forconsecutive 30 days. The body, spleen, thymus weight were observed, study on theeffect of the drug on the cellular immune function by proliferation and transformationof spleen lymphocytes test; study on the effect of the drug on the humoral immunefunction of mice by serum erythrocytolysin test; study on the effect of the drug on themononuclear macrophage function by carbon clearance and neutral red test.

实验方法 1设玉米油对照组和低、中、高三个灵芝孢子油剂量组，连续灌胃30天后观察小鼠体重、胸腺、脾脏重量指数；采用吞噬中性红和碳廓清实验测定对小鼠单核-巨噬细胞功能的影响；血清溶血素实验测定对小鼠体液免疫功能的影响；ConA诱导脾淋巴细胞转化实验测定对小鼠细胞免疫功能的影响；MTT法测定对小鼠NK细胞杀伤活性、脾细胞产生TNF-α和IL-2含量的影响。

The cause of hindering the gynospore formation was short of boronin chestnut orchard,which led to the poor pollination and a decrease ofendogenous GA1/3, iPAs level and an increase of endogenous ABA level in ovary,which restrained the mother cell division of gynospore.The low level ofendogenous GA1/3,iPAs contents and the increase of endogenous ABA contentcaused a serious lack of reducing sugar,starch,protein and potassium in ovary,which led to a cease of young embryo development.

其中，大孢子形成过程的停滞是由于栗园B素缺乏，致使授粉不良和子房内源GA1/3、iPAS等含量下降，ABA含量上升，从而抑制大孢子母细胞分裂；幼胚发育停滞则是由于子房内源GA1/3、iPAS等生长类激素的上升启动受阻，继续处于低水平，ABA上升，使子房中还原糖、淀粉、蛋白质和K素积累受阻，造成营养严重缺乏。

Sp. tritici conidiospores. 40 h after inoculation, penetration of the fungus and formation of haustoria in transformed cells were observed to evaluate the effect of the target gene's product on the invasion of the fungus.

基因枪轰击后高密度接种白粉病菌孢子。40h后观察转化阳性表皮细胞度其表面抱子的发育，并以阳性转化细胞中白粉病菌成功侵入的细胞所占比例为指标分析目标基因的表达对白粉病菌入侵及吸器形成产生的影响(对照为单独导入GUS基因的表皮细胞)。
