With American botanist cypress apply reach Halier, the really beautiful doctrine that British botanist breaths out Qin Song to be a delegate thinks the flower of angiosperm is come by evolution of ball of leaf of primitive gymnospermous bisexual spore, consequently tentative idea angiosperm is the Benneisu that in coming from gymnosperm, eradicates already iron eye, draft Su Tie especially , the bud on ball of its spore leaf piece evolve for perianth, sporule leaf evolves for stamen, big spore leaf evolves for pistil , axis of ball of its spore leaf shortens for rachis.

以美国植物学家柏施及哈利尔，英国植物学家哈钦松为代表的真花学说认为被子植物的花是由原始裸子植物两性孢子叶球演化而来，因而设想被子植物是来自裸子植物中早已灭绝的本内苏铁目，非凡是拟苏铁，其孢子叶球上的苞片演变为花被，小孢子叶演变为雄蕊，大孢子叶演变为雌蕊，其孢子叶球轴则缩短为花轴。

Biological characteristics of Curvularia lunataBoedijn had been preliminarily studied. Optimal mediums for pathogen growth were PSA,PDA and OMA.For mycelia growth,sporulation and conidial germination of pathogen,optimal temperature was 25～30℃,and pH 5～9.Among the tested carbon and nitrogen resources,sucrose,glucose,carbamide,sodium nitrate,etc were beneficial for mycelia growth and sporulation.The conidia germination is strict in RH requirement:Conidia can germinate at RH 81%～98%,or have 100% germin...

香蕉大灰斑病菌适合生长的培养基有PSA、PDA和OMA；菌落生长、产孢和孢子萌发最适宜的温度为25～30℃，pH 5～9；在碳源和氮源中，蔗糖、葡萄糖、尿素、磷酸氢二氨和硝酸钠有利于病菌生长和产孢；分生孢子萌发对湿度有严格的要求，RH≥80%以上分生孢子萌发，随湿度增加萌发率增高；光照对菌丝体无显著影响，光暗交替有利于孢子的形成；孢子致死温度为55℃(10min)。

It was found that the fungus 1403 resembles pathogenic F. verticillioides (teleomophy Gibberella moniliforme) in the production of false head or chains and abundant microconidia on the aerial mycelium, but different in the occasional formation of polyphialides with relatively long as well as short monophialides, in its typical coiled hyphae and mycelia fusion.

基于1403在形态学方面具有以下特征：产小型分生孢子的分生孢子梗较长，小型分生孢子呈椭圆形，大型分生孢子线形或略微弯曲，本文将它与有类似形态特征的镰刀菌进行了比较，发现1403与植物病原菌Fusarium verticillioides（有性态为Gibberella moniliforme）表面上很相似，气生菌丝均可产生大量假头状或链状的小型分生孢子，但深入的研究却发现1403与F。

The degradation of trehalose into smaller molecules such as glucose or fructose under the catalysis of trehalase is the biochemical base of the germination of aquatic microsporidian spores .

内部渗透压的升高是微孢子虫孢子发芽的直接驱动力，海藻糖酶催化海藻糖水解为葡萄糖或果糖是水生型微孢子虫孢子发芽的生化基础，p H值、离子种类及浓度、温度、射线等均能影响孢子发芽。

It has been reported in the literature at home and abroad, has now been discovered and named after the goat meat carinii three were Sarcocystis goat dog, goat and dog Sarcocystis Sarcocystis Moore, one of the first two relatively common, Sarcocystis Moore reported relatively small.

据国内外的文献报道，现在已经发现并命名的山羊肉孢子虫有三种，分别是山羊犬肉孢子虫、家山羊犬肉孢子虫和莫尔肉孢子虫，其中前两种比较的常见，莫尔肉孢子虫报道的比较少。

Paraffin slides observation found that the microspore of the RNMS line failed to vacuolate after its morphogenesis, disassembled and disappeared at last. After microspore morphogenesis, the breaking down of tapetum cells was delayed until microspore breading down.

石蜡切片细胞学观察，发现该隐性核不育能形成正常的四分体孢子，四分体释放出小孢子后，在单核花粉进入液泡化时小孢子的发育异常，不进行正常的液泡化，逐渐开始解体和消失；相应的绒毡层在小孢子形成后的降解延迟，绒毡层细胞的体积略有增大，在小孢子降解快结束时也很快解体。

Bipolaris sorokiniana may affect turf grass to cause leaf spot, bud rot, seedling blight, root rot, sheath rot. The temperature range of colony growth is 10～40℃, the optimum 25℃. Conidia can germinate in the temperature range of 20～35℃, and germinate best at 28℃; Conidia germinate well on slide water surface, contrary to other different methods, and they can germinate well under given air condition, but germination is not strict with nutrition. The inhibiting test of 8 kinds of fungicide showed Sporgon 50WP was most effective, and the inhibiting effect of the others was well to the conidia germination.

Bipolaris sorokiniana能浸染草坪禾草叶片形成梭形病斑，并可导致芽腐、苗枯、根腐、茎基腐、鞘腐等症状；病原菌在10～40℃下能够生长，最适生长温度为25℃；病原菌分生孢子在不同萌发条件中以水平萌发较好；分生孢子萌发需要空气条件，但对营养要求不严格；在20～35℃下分生孢子均可萌发，以28℃下萌发最好；八种不同药剂对病原菌的抑制效果表明，50%施保功可湿性粉剂1500倍液效果较好，其抑菌圈直径和抑制分生孢子萌发率分别为46.2mm和81.3%，其他几种药剂对孢子萌发也有较好的抑制作用。

The results showed that BS-LX04 had strong antagonistic activity on the mycelia growth and conidia germination. The hyphae were suppressed by BS-LX04 and presented malformation. The conidia germination was inhibited, with an inhibition percentage of 73.22% when examined at 24 h after test. The germination was delayed by BS-LX04 and the germ tube and hyphae also presented malformation though some of the spores germinated and formed hypha.

结果表明BS-LX04对桑炭疸病病原菌的菌丝生长和分生孢子萌发具有较强的拮抗作用：能够使菌丝生长受阻且產生畸形；能够抑制分生孢子的萌发，培养24h检查孢子萌发抑制率为73.22%；能够推迟分生孢子的萌发时间，並导致萌发孢子的芽管和菌丝畸形而不能继续生长。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.
