Abstract: This paper gives a general statement about the present development of chilling-resistant mechanisms of plants at home and abroad, and it deals mainly with the relations between the chilling-resistance of plants and cell membrane system,enzyme system diverisity and chilling-resistant gene expression and control. In addition, the paper points out some problems worth delibrating deeply in the research field of plant chilling-resistance.

Abstract: This study analyzed five varieties of P. tomentosa and their putative parents, P. alba, P. davidiana, P. adenopoda and P. tremula by RAPD and artificial cross. Of 78 bands revealed by 13 arbitrary primers selected, 58(74.36%) bands were polymorphic among P. tomentosa and four putative parents. The RAPD statistical results showed the relationship between P. tomentosa and P. alba or P. adenopoda was closer than that between P. tomentosa and'P. davidiana or P. tremula . There were higher similarity and lower genetic distance between P. tomentosa and P. alba or P. adenopoda than that between P. tomentosa and the other two putative parents. The results from UPGMA, Fitch-margoliash phylogenetic dendrogram were similar. In addition, artificial hybrids including reciprocal cross between P. alba and P. adenopoda were used to compare with five varieties of P. tomentosa . And those hybrids between P. alba as female and P. adenopoda as male were closer to P. tomentosa than those from reciprocal cross. The results demonstrated that P. tomentosa was a natural hybrid between P. alba as female parent and P. adenopoda as male parent.

Abstract: Considerable knowledge about the biology of forest tree has been gained in the recent years by the application of the new genomic technologies to study tree growth and development as well as the response of trees to biotic and abiotic stresses. Proteomics is becoming an important content in the biology of forest tree. A review is given about the progress in forest tree proteomics research in the areas of population genetics, genetic mapping, stress physiology, organs and tissues, and wood formation, etc. Furthermore, forest tree proteome database is briefly introduced. Finally, the prospect of proteomics is discussed.

Abstract: In view of the shortcomings of slow rate of convergence and easy to fall into local optimal solution for the tra- ditional ant algorithm, this paper put forward to improve distance heuristic factor to encrease effects on the next node, so as to enhance the global search ability, avoid trap in local optimal solution and improve the rate of convergence. Con- sidering the complexity and diversity of the real environment, this paper introduced multiple path quality constraints to improve the rules of the pheromone update. I}he simulation results show the improved ant colony algorithm has a good effect in the dynamic path planning.

Abstract: The isothermal crystallization kinetics of amorphous Al-Ni-Zr alloy produced by mechanical alloying was studied by means of differential scanning calorimetry. Accordiag to Arrhenius equation, the apparent activation energy was calculated. The isothermal crystal-lization kinetics follows Johnson-Mehl-Avrami equation with n=2.00 within 0.15

Abstract: The composition of molecular species and the positional distribution of fatty acids of phosphatidylglycerol (PG) isolated from Ginkgo leaf were examined and analyzed by high-perfor-mance liquid chromatography (HPLC) and enzymic hydrolysis. The fatty acid compositions (sn-1/ sn-2) of the identified major mglecular species were 18:3/16: 1(30,18:3/16:0,18:2/16: 1(3t),18:2/16:0,18:1/16: 1(3t,16:0/16:1 (3t), 18: 1/18: 1,18:1/16:0 and 16:0/16:0. The results showed that C18 fatty acids were principally localized at the sn-1 position, the component 16:1 (3t exclusively occupied the sn-2 position and 16:0 was found at both the sn-1 position and the sn-2 positon. The degree of unsaturation at the sn-1 postion was higher than that at the sn-2 positon.

Abstract: 本文利用RAPD标记和美洲黑杨(Populus deltoides)×欧美杨(P.euramericana)的F1群体,构建了美洲黑杨×欧美杨的分子标记连锁图谱。实验过程中对1040个寡核苷酸随机引物进行了重复筛选,共选出127个引物用于作图群体(包括双亲共92个无性系)的随机扩增,这127个引物产生229个多态基因座,其中符合“拟测交”1∶1分离的有214个。利用多点连锁分析,形成19个连锁群及6个三连体和14个连锁对。由19个连锁群构成的图谱含标记129个,总图距为1914.2cM,覆盖杨树基因组约73.62%。标记间的平均间距为14.84cM。本研究获得了中等密度的美洲黑杨×欧美杨的一个连锁框架。 Abstract:A molecular linkage map was constructed for the parents of a P.deltoides × P.euramericana F1 family based on random amplified polymorphic DNA(RAPD)markers.A set of 1040 random oligonucleotide primers were screened and 127 primers were selected to generate RAPD markers within a sample of 90 F1 progenies.A total of 229 segregating loci were identified.Among the 229 loci,15 loci were found distorted from the normal 1∶1 ratio.Using multiple analysis,the 214 markers formed 19 main Linkage groups (including 129 markers)and b triples and 14 pairs.The resulting Linkage map of Populus deltoides × P.euramericana (including 129 markers)spanned 1914.2cM(73.62% coverage of genome length)wi
