白千层

The average fiber length of 2-yr-old Melaleuca leucadendron is 0.75mm. Its holo-cellulose content is merely 64.4%, lower than those of Gmelina arborea of the same age and mixed Indonesian hardwoods. Lignin content of the wood is 30.7%, higher than that of Gmelina arborea of the same age and close to the average of SE Asian hardwoods.

二年生白千层之纤维长度平均值为0.75mm，在化学组成分中，全纤维素量仅64.4%，低於同龄级之速生云南石梓材及印尼混合材，而木质素含量为30.7%，高於同龄级速生云南石梓材，而与南洋材之平均值相近。

Comparing Melaleuca leucadendron with Gmelina arborea of the same age, the former has shorter fibers, but the 2 have similar single-fiber strengths. The unbleaehed pulps of the 2 species have comparable composite strength indices.

比较相同二年生速生树种白千层及云南石梓，前者漂白浆纤维较短，但单纤维强度二者相近，且未漂白浆之综合强度指数与同龄级之速生云南石梓材者相若。

The result would be used in tobacco breeding.4 SRAP technology is used to study the genetic differences among different types of tobacco, including flue-cured tobacco, oriental tobacco, maryland tobacco, burley tobacco, and air/sun cured tobacco, five pairs of primer combinations which can amplify characteristic bands has been screened. Among the five combinations, two of them (SF25*SR2 and SF3*SR26) can distinguish air-cured tobacco including maryland tobacco and Burley tobacco from the other cultivated forms; SF20*SR14 can distinguish sun cured tobacco including oriental tobacco and sun-cured tobacco; SF16*SR14 can distinguish flue-cured tobacco and air-cured tobacco, and SF22*SR14 can distinguish DBJ599 with specisl aroma and the other flue-cured tobacco.5 8 varieties , which represent the different types of tobacco, are divided into 3 groups. I: G-28, II:DBJ599、MD40、By21, III: Basma、Sumsun、XNS、QCT. The cluster analysis result es consistant with experience evatuation.6 Anorthogonal design was used to optimize a ILP-PCR system with 5 factors (DNA, Mg2+, dNTP, primer and Taq polymerase) at 4 levels.The result showed the optimized ILP-PCR system for Nicotiana tabacum L. was: 2uL10×PCRbuffer, 20ng template DNA, Mg2+ 2.0mmol/L, dNTP 150umol/L, primer 0.3umol/L, Taq DNA polymerase 1 U in a total of 20uL reactionsolution.

研究结果可作为烤烟与香料烟类型间的杂种鉴定利用的实验与理论依据。4、利用SRAP标记技术，研究和分析了烤烟、晒烟、晾烟、白肋烟、香料烟等不同栽培类型间的基因型差异，初步筛选出了能够在分子水平上反映不同烟草类型差异的特征性标记带：晾烟MD40、Ky17、Burley21、TN90基因型共有的特征带有两对引物组合，分别为SF25*SR2和SF3*SR26；晒烟小牛舌、青梗、小花青和香料烟Sumsun、komotini Basma、Xanthi Basma共有的特征带引物组合为SF20*SR14；NC89、K326、G-28、大白筋和MD40、Ky17、Burley21、TN90共有的特征带引物组合为SF16*SR14，烤烟中大白筋599的特征带引物组合SF22*SR14.5、利用61对SRAP引物组合，研究了普通烟草不同类型间的亲缘关系，将普通烟草类型间8个不同供试材料划分为3类别。I：烤烟类型G-28II：白肋烟类型(MD40、By21、大白筋599III：香料烟类型(Basma、Sumsun、小牛舌、千层塔)。

When the winter visits the Barclay Memorial Park, Taiwan Goldenrain tree and the common bald cypress are stepping into winter's stage, but big cosmos is already impatient before the spring approached, blooming the multi-colored flowers.

当冬天造访巴克礼公园时，台湾栾树和落羽松却不肯向命运屈服，勇敢的登上冬天的舞台，白千层应景的穿上了雪白的衣裳，但大波斯菊却已迫不及待的在春天还未来临之前就绽放著五彩缤纷的花朵了。
