Our observations indicated that the occurrence of M.pubescens var.alba was related to the sympatric distribution of M.erosa,which has yellow flowers and thus compete with M.pubescence var.pubescens for the same pollinators. Our studies suggested that M.erosa and M.pubescens var.pubescens share the same Lepidoptera pollinators,while the effective pollinators of M.pubescens var.alba are Hymenoptera. Primary conclusions could be drawn that the emergence of M.pubescens var.alba is a phenomenon of reproductive character displacement.]]> 2016/1/20 15:35:17 1,2, LUO Zhong-Lai¹, ZHANG Dian-Xiang^1*]]> LAI Ming^1,2, LUO Zhong-Lai¹, ZHANG Dian-Xiang^1* 10true Platycodon grandiflorum was carried out between male sterile and male fertility varieties by farming observation and paraffin section method. The results showed that male fertility had no obvious differences with male sterile in morphology and anther's length of flower,but after flowering,male fertility had full and lustrous anthers with pollen granule spilled out,male sterile had shiriveled and lacklustre anthers with empty pollen. Tapetum layer of male sterile was degenerated and disappeared before fertility,leading to the degradation and finally abnormal development of the microspores.]]> 2016/1/20 15:35:17 WU Song-Quan, QUAN Xue-Li, PIAO Xue-Mei, YAN Yi-Zi, WU Ji-Ri 9true Rhodiola fastigiata is national second-class protected species and in approximately endangered states in China. Increment in length and diameter of rhizome per year were measured using vernier caliper(IP54 type)through observing the scape rings formation of R.fastigiata in different altitude areas of Tibet Sejila Mountain,and then the growth characteristics of rhizome were analyzed to determine the age. The results showed that:R.fastigiata form one scape rings in the rhizome yearly,furthermore,there was no significant difference in length and diameter of rhizome increment at different years,whereas with the altitude increase,increment in length and diameter of rhizome per year was declining. The R.fastigiata's age could be determined according to the rhizome growth characteristics,combining with the length of the rhizome. So this result could lay the of foundation for further population structure and dynamics study of R.fastigiata.]]> 2016/1/20 15:35:17 1,2, TIAN Da-Lun¹, DING Yu-Ke², LU Jie^2*, ZHANG Jian-Xin²]]> ZHENG Wei-Lie^1,2, TIAN Da-Lun¹, DING Yu-Ke², LU Jie^2*, ZHANG Jian-Xin² 8true Rhinopithecus roxellana distributing. Based on the former 2 years' field survey data,the plant flora in Rh.roxellana habitats at Shennongjia was analyzed to provide evidence for the biodiversity evaluation after disaster and recovery construction of Rh.roxellana habitats. The field survey found that there are 255 woody plants belonging 44 families 105 genera,which contain arbor 23 families 51 genera 129 species,shrub 22 families 49 genera 113 species and woody climber 7 families 9 genera 13 species. According to the statistics,31 families 58 genera 85 species plants are the feeding plants of Rh.roxellana. 58 genera(accounting for 56.30%)are predominant in number which are the temperate type distribution. 58 genera are the tropical type distribution and 23 genera are the East Asia and China special distribution which account for 21.36% and 22.33% respectively. The above information indicates that this area is a transitional region from subtropical zone to temperate zone. The paper counted up the pedigree of food resources in habitat and analyzed the food resources characteristics of this area as well.]]> 2016/1/20 15:35:17 1,2, ZHANG Jing¹, PENG Lin-Peng³, LIAO Ming-Yao³, YANG Lin-Sen³, ZHANG Zhi-Xiang^1,4*]]> TIE Jun^1,2, ZHANG Jing¹, PENG Lin-Peng³, LIAO Ming-Yao³, YANG Lin-Sen³, ZHANG Zhi-Xiang^1,4* 7true 2016/1/20 15:35:17 1, LI Zhen¹, Dang Xuan Phong², Matsumoto Eiji³, JIANG Hui¹]]> LI Jie¹, LI Zhen¹, Dang Xuan Phong², Matsumoto Eiji³, JIANG Hui¹ 6true Primula. This review tried to provide the theoretical base for primroses protection by summarizing the progress of primrose conservation genetics. The paleontology failed to give information of primroses speciation,while the phylogeography did it well. We also described the latest progress in primroses phylogeographies,and sorted out the patterns of divergence,which is important for precise prediction regarding the response of primroses to global climatic changes.]]> 2016/1/20 15:35:17 1, WANG Feng-Ying², HAO Gang^3*]]> YAN Hai-Fei¹, WANG Feng-Ying², HAO Gang^3* 5true Arabidopsis and rice),genomic sequencing project,the emphasis of plant genomic research has focused on functional genome research.

The results showed that -20 ℃ was a better way for sample preservation and the modified CTAB method was a better method for DNA extraction than others. The UV detection value of A₂₆₀/A₂₈₀ was 1.7-1.8 for DNA extracted by this modified CTAB method,obviously higher than that of others,such as 1.1-1.5 for SDS method,1.2-1.5 for CTAB method,1.4-1.6 for SDS-CTAB method.

After that,the chlorophyll content,soluble protein content,antioxidant system,active oxygen generation and ultrastructural changes in leaves were investigated. The results showed that with increasing concentration of Pb²⁺,the chlorophyll content,chlorophyll a/b,soluble protein content and CAT activity decreased; SOD,POD,APX,GR activities,AsA and GSH content increased at first and then decreased; O^-₂· generation rate,H₂O₂,MDA and soluble sugar content increased; SDS-PAGE revealed that Pb²⁺ reduced the amounts of polypeptides with apparent molecular weights 16.3kDa and 55.0kDa,while three polypeptides with apparent molecular weights 23.1kDa,75.8kDa and 94.0kDa disappeared with the increasing of Pb²⁺ concentration; transmission electron microscopy observation indicated that the higher Pb²⁺ concentration,the more serious damages the chloroplast,mitochondria and nucleus suffered. It was concluded that physiological and structural foundations in the normal metabolism of Hydrochairs dubia would be destructed by Pb²⁺ stresses,leading to the disorder of metabolic balance and finally causing the death of the plant.]]> 2016/1/20 15:35:17 *,XU Qin-Song, YANG Hai-Yan,XU Ye,XU Xiao-Ying]]> DING Chun-Xia,SHI Guo-Xin^*,XU Qin-Song, YANG Hai-Yan,XU Ye,XU Xiao-Ying 2true Croton tiglium from Guangxi were digestion by high pressure digestion jar,The microelements in different parts of C.tiglium were determined by ICP-AES.
