A.sinicus )in enhancing phytoremediation. The finding is that the microbes of rhizosphere soil are generally more active than those of bulk soil. Such result has little to do with microbes whose carbon sources are phosphate,carboxylic and amines. Instead,the result attributes mainly to microbes whose carbon sources come from amino acids,glucide,FAT and alcohols. It's also found in the further research that,while the growth of microbes utilizing carbon sources(γ-Hydroxybutyric Acid and Phenylethyl-Amine included),is suppressed,new microbes emerge in rhizosphere soil,namely,ɑ-Ketobutyric Acid,2-Hydroxy Benzoic Acid,4-Hydroxy Benzoic Acid,D-Glucosaminic Acid,ɑ-Cyclodextrin,D-Xylose,β-Methyl-D-Glucoside,D-Mannitol and L-Arginine; that while Rhizosphere secretions of A.sinicus inhibit microbes utilizing D-Malic acid and Itaconic Acid and Glycogen as carbon sources,it promotes other microbes utilizing D-Cellobiose,N-Acetyl-D-Glucosamine,Pyruvic Acid Methyl ester,Tween 40,Tween 80,L-Phenylalanine,L-Asparagine and Putrescine as carbon sources,and has no effect on microbes utilizing D-Glucosaminic acid,α-D-Lactose,and Í-Erythritol as carbon sources. Another finding of the study is that even microbes derived from the same carbon source may perform differently at rhizosphere of A.sinicus. To illustrate,the growth of microbes feeding on D-Talactonic Acid,γ-Lactone and L-Serice is largely inhibited at first but be promoted in later; likewise,microbes that utilized Glycyl-L-Glutamic Acid as carbon sources perform just the opposite to general conception. A possible conclusion is that the population structure and liveness of microbes of the A.sinicus rhizosphere may contribute to the absorption of the heavy metals in the soil and the growth of accumulators.]]> 2016/1/15 21:07:58 1*, ZENG Heng², HUANG Yu-Yuan³, JIAN Min-Fei¹, ZHU Du¹]]> NI Cai-Ying^1*, ZENG Heng², HUANG Yu-Yuan³, JIAN Min-Fei¹, ZHU Du¹ 37true 2016/1/15 21:07:58 1, CAO Qiong-Hui¹, HUANG Feng¹, YUAN Lin²]]> WANG Hong-Wei¹, CAO Qiong-Hui¹, HUANG Feng¹, YUAN Lin² 36true Artomisia annul plant and the contents of artemisinin were investigated and analysed.

It was beneficial to the growth of A.annul and artemisinin accumulation by fertilizing,supplying to Ca,P properly,improving the nutrient status of soil and so on,reduing the ratios of N in the roots to N in the stems and N in the stems to N in the leaves,adjusting the plant nutrient content in the plant.Supplying to fertilizer K can also enhance the growth of A.annul.]]> 2016/1/15 21:07:58 QI Xiao-Xue, WEI Xiao, JIANG Yun-Sheng, CHEN Zong-You, TANG Hui, LI Feng 35true Eupatorium adenophorum on seed germination and growth of 3 native plant seedlings in karst area was determined with bioassay method. The results showed,except for the lowest concentration(0.0125 g/mL),the aqueous extract from leaves and roots of E.adenophorum could significantly inhibit the rate and speed of seed germination and growth of seedlings of Toona sinensis,and the higher of the concentration,the better effect of the inhibition. The aqueous extract also had effects of inhibition on rate and speed of seed germination and growth of seedlings of Zenia insignis and Bauhunia championii,but the effects were relatively weak,even sometimes were positive impacts.

Stomatal density was about 200 to 300 per square millimeter.

The results showed that epidermal cells of the stems and leaves were small,and the well-developed horny layers of the cells with abundant tanning were found. Periderms of stems were absent in 1-2 year-old individuals. Ordinany parenchyma of cortex was composed of 5 lamellas. The cross section of stem seemed to be quincuncial. Periderms in stems of 3-year-old individuals were found,followed by the finding of developed parenchymatous tissue with abundant cellular contents in the secondary phloem. Midvein had the same corneous layer emulsion swelled of stomatal band in the lower epidermis of leaf,and the papillate was dense and large. Stomas with bicyclic stomatal apparatus of the leaves were only detected in the lower epidermis. The spongy tissue constituted a three-quarter proportion in the thickness of the mesophyll. Further analysis indicated that the anatomy structures of stems and leaves were considered as adaption to the mid-subtropica mountain climatic and shade environment. Opposite to previous studies,it was found that the corneous layer emulsion swelled is spread all over the lower epidermis of leaf,which were correlated with the higher elevation and lower temperature of the habitat.]]> 2016/1/21 12:11:50 1,2, LIANG Shi-Chu^1,2*]]> LI Feng-Ying^1,2, LIANG Shi-Chu^1,2* 3true 2016/1/21 12:11:50 1,3,4, ZHU Jian-Hua^2*, PENG Hong-Xiang², HE Xin-Hua¹]]> SHEN Qing-Qing^1,3,4, ZHU Jian-Hua^2*, PENG Hong-Xiang², HE Xin-Hua¹ 2true Anoetochilus emeiensis,Coptis omeiensis,Parakmeria omeiensis,Bergenia emeinsis and so on. 35 species,29 genera and 22 families which needed protection accounted for 23.02%,28.43%,39.29% respectively,and their representatives included Manglietia szechuanica,Viburnum omeiensis,Lonicera similes and Hemsleya omeiensis. 76 species,59 genera and 41 families which needed unclassified protection accounted for 50%,57.84%,73.21% respectively.
