Three kinds of plant expressing vector pC1304- CamV35S+ Cbcor15b, pC1304-cold-induced promotor+ Cbcor15b*, pC1304- CamV35S+ Cbcbf for transforming dicotyledon plants was constructed successfully by substituting the report gene of pC1304 with the coding sequence of our destination gene. The recombinant vector was introduced into Agrobacterium tumefaciens with freeze-thaw method. The leaf discs of tobacco plants infected by A. tumefaciens were selected with hygromycin. The regenerated plants were tested by PCR.

It was worth to note that the HI titer of monovalent vaccine immunized group challenged with the same type reached the peak earlier than that challenged with different type virus, whereas there was no such difference among multivalent vaccine immunized groups. It suggested that NDV immunogenicity among epizootic isolates and vaccine strains were also variable in some extent.

单价免疫组鸡对相同基因型NDV 刺激产生的回忆反应要比对具有不同基因型NDV 刺激产生的时间要早，多价灭活苗免疫组对抗原刺激产生的回忆反应基本相同，说明不同流行株在抗原性上存在一定的差异。

The seedlings which did not grow and grew slowly(vitrification, browning and etiolation) were not included

注：成活率是指生长良好，株高1.5 cm以上的小植株，不生长或生长缓慢苗不计。

According to several years practice, comprehensively sum up measures of forcing culture technology of scale and dwarf on potted Bougainvillea as: a propagation of cuttage, which choose a mixture of 50%peat, 33% vermiculite and 17 sharp sand as cutting soil, and choose a semi-wooden shoot cut into 5~10cm length with 2~3 leaves as cuttings then touch 1% AA root powder, is lower cost and higher survival rate than that of tissue culture; Bougainvillea growth can be efficaciously regulated by pruning and using 2~5g/L PP333; bougainvillea can be induced to flowers by spraying 2.5~4.0g/L B9 and administering no more 11 hours daylight every day continuously; the florescence can be more prolonged about 20 days by spraying 50mg/L NAA while selling; and prevention and cure of pest and disease, etc.

根据多年的生产实践，从科学育苗、栽培管理、售前处理和病虫害防治等方面综合总结了叶子花的规模化矮化促成生产技术措施：选择泥炭土、蛭石和黄沙按3：2：1比例混合均匀的扦插基质，采用半木质化当年生枝条，剪成5~10cm长的2~3叶节一段，沾染1%自制生根粉的扦插育苗较组培育苗成本低，成活率高；结合修剪用2~5g/L的多效唑进行叶面喷洒能有效控制生长，矮化植株；选择2.5~4.0的丁酰肼叶面喷洒和每天保持不多于11h的短日照处理，能有效促进开花；销售前全株喷洒脱50mg/L NAA可延长花期20天左右；整个生产过程加强肥水管理、温湿度控制和环境清洁能有效防治病虫害发生。

The efficiency of octoploid triticale anther culture was practically onthe same level as that of common wheat,namely,2.5 green pollen plants per hundred an-ther.
