| 1. | A properly managed stand will remain reasonably productive for two years .
管理适当的草场能保持旺盛生长两年。 |
| 2. | Auxins are produced mainly by young developing leaves on actively growing shoots .
生长素主要是从旺盛生长新梢上正在发育的幼叶产生出来。 |
| 3. | It produces valuable lumber and thrives on sites too dry for most other large trees .
它能生产有价值的方材并能在非常干旱、其它多数大乔木长不了的地方旺盛生长。 |
| 4. | Such heavy branches tend to grow vigorously in later years and render difficult the maintenance of an acceptable tree shape .
这种强壮枝在以后年代里易于旺盛生长，给保持植株合理的树型造成困难。 |
| 5. | The expression level increase during the vigorous growing period
在发育过程中，其表达随着旺盛生长而逐渐上升。 |
| 6. | It flourishes in tumor tissue because there is often marked anaerobic glycolysis occurring
这种细菌往往由于条件适合，在高度糖酵解的肿瘤组织中旺盛生长。 |
| 7. | 20 - oxidase expressed very low in expanded leaves of apple , it suggest that the ga intermediates synthesis by the expanded leaves may transport to other vigorous growing tissue as raw material for those tissue
20 -氧化酶在苹果成年叶中表达量很低，说明上游合成的赤霉素中间产物有可能外运作为其它旺盛生长组织的ga合成原料。 |
| 8. | In this thesis , a strain of associative nitrogen fixing bacteria with high nitrogenase activity was selected and the further studies for it were conducted , the results obtained are as follows : selection and identification of associative nitrogen fixing bacteria with high nitrogenase activity . the nitrogenase activities detected by means of the acetylene reduction method and growth rates tested by optical density of germ suspension under the x 400nm ( od4oo ) of all the strains tested except for the strain w12 reduced gradually due to frequent subculture during a year . however , the strain w12 has been showing high and stable nitrogenase activity and growth rate since it was isolated five years ago
固氮菌株的筛选与鉴定：测定从不同来源分离、收集和保藏的12个固氮菌株或分离物在不同保存时期的固氮酶活性和生长能力，发现多数菌株在初分离得到时固氮酶活性较高，但随着转接次数的增多却逐渐丧失固氮酶活性，生长也随之减弱，只有w12在五年前从埃及分离得到至今一直保持旺盛生长势和较高的固氮酶活性， 48h内乙烯生成量可达1800nmol乙烯ml菌液以上，远远高于其它菌株，其生长量( od _ ( 400 )值)也远远高于其它菌株。 |
| 9. | 4 . we use half quantification and digoxigenin detection to investigate the expression pattern of ent - kaurene oxidase . we found that it was regulated by development , it expressed high in the fast growing tissue , expanded leaves under a fast growing circumstance also express high level of ent - kaurene oxidase
利用半定量rt - pcr的方法结合地高辛标记法，贝壳杉烯氧化酶在果树中的表达是受发育调控的，其在旺盛生长的组织中表达量高，在植株旺长期的成年叶中表达量也很高。 |
