The paper adopted the common breeding way by series of mutagen treating to the yeast ' s cell and spheroplast. finally, the excellent mutant 75l 3555 was obtained. its nature of the production was determined and it can product ethanol on the condition of 40 and have high fermentative speed and stable production. on the other hand, the test was made that the best fermentative condition was found. in the malt juice, adding 0. 02 % k + or 0. 03 % a13 + can increase the production strikingly and adding some degree concentration trahalose can increase the production too and cut short the time of taming. in the study of using molasses producting ethanol, we can obtain high productivity contained the following composition : nitrogen source 1. 5 % maize and 0. 075 % ( nh4 ) 2so4
本實驗以常規的育種方法，通過對酵母細胞懸液和原生質體進行一系列誘變，經過大量的篩選，最終選育出一株耐高溫高產菌株75l _ （ 3566 ） ，並對其進行了生產性能的測定。 75l _ （ 3566 ）在40條件下，濃度為20 bx的麥芽汁發酵液中，產酒率高達11 . 5 ，而且發酵速度快，發酵周期可縮短12h ，其生產性能穩定，可以適應大部分以澱粉質為原料的生產廠家的需要。同時本實驗對75l _ （ 3566 ）進行了發酵條件優化的初步研究。 -

Then, the plasmid was transformed into jm109. the full length pstvd cdna recombinant plasmid was further identified by restriction mapping analysis and the nucleotide sequence of cdna cloned in pmd 18 - t vector was analyzed with ab1 377 dna sequence. test showed that the cdna of this chinese pstvd isolate was the same as pstvd - kf - 6 mild " type " isolate which originated from naturally infected potatoes in field of cornell university potato breeding program
利用rt - pgr技術，設計一對引物，對田間採集的經鑒定含pstvd的陽性樣品進行全序列擴增，並將所得產物純化回收，連接到pmd18t - vector中，並轉化至大腸桿菌jm109中，挑選白斑進行雙酶切（ saci / ecorv ）鑒定證明插入片段為359bp大小，進行序列測定，所得克隆基因為pstvd全序列負鏈，大小為359bp 。 -
Genetic variations in different levels of masson pine ( pinus massoniana lamb. ) in main traits were studied on the basis of the 12 - year - old data of provenance tests at 7 test locations and the 11 - year - old data of plus progenies at 2 test locations, and the index and strategy in different variation levels on selection breeding for pulpwood in masson pine was also discussed

Introduced infected by the turnip mosaic virus. there are many useful objective genes can be used in vegetable genetic transformation, but the research work of chinese cabbage genetic transformation is little. the reaserch on transforming chinese cabbage using agrobacterium - med ated method has n ' t been report at home and abroad. ln the test, tumv - cp gene was transferred into chinese cabbage ( brassica campestris l. ssp. pekinensis ) via agrobacterium - mediated method. a high effective regeneration and genetic transformatin system has been established, the detection by the method of molecular biology, has proved that the regenerative plants are transgenic plants and the target genes have been expressed transgenic plants partly. meanwhile transgenic progenies were traced and investigated so that heredity, stability and expression of target gene were researched. the virus resistant, stable plants were expected to obt ain so that theoretical base can be established for chinese cabbage breeding by gene engineering
