The results showed that the transpiration rate(E),stomatal conductance(GH₂O)and photosynthesis rate(A)decreased under SA stress,while these decreases were anesised by the addition of eATP. However,SA had no significant effects on the chlorophyll fluorescence parameters,and the addition of eATP did not significantly changed the values of the chlorophyll fluorescence parameters under SA stress. These results indicated that SA could inhibit photosynthesis of tobacco leaves and the addition of eATP could alleviate the inhibition of photosynthesis by SA stress,while these effects were not related to the light reaction. We also discussed the possible mechanism based on these observations.]]> 2015/12/15 11:20:20 *, JIAO Qing-Song]]> FENG Han-Qing^*, JIAO Qing-Song 8true 2015/12/15 11:20:20 *, YAN Xiao-Jie, LI Dian-Peng]]> YANG Zi-Ming, LIU Jin-Lei^*, YAN Xiao-Jie, LI Dian-Peng 7true Carthamus tinctoricus and the rhizosphere soil were determined by ICP-AES technique to study the law of mineral elements absorption and accumulation in the plant. The results indicated that the contents of K、Fe and Zn in seedlings are higher than that in other parts of plant,the contents of Ca and Mg in mature leaves are higher than that in other parts of plant,the content of Cu in seeds is highest in all Cu contents in different parts of the plant. K and Ca in seeds are less than these in other parts of plant. Mg,Fe,Cu and Zn were respectively least in flower,stem,mature leaves and stem. Therefore,K markedly accumulates in seedling and flower,Cu is obviously absorbed in seedling and seeds,Ca mostly accumulates in mature leaves. There are obvious differences in the absorption of these mineral elements in C. tinctoricus. These mineral elements that are absorbed much should be complemented as fertilizer when plant C. tinctoricus.]]> 2015/12/15 11:19:56 *, XU Gui-Fang, SONG Lin-Lin, CHEN Hong-Zhi, HU Xi-Qiao, CHENG Yuan-Gang]]> JIAN Zai-You, MENG Li^*, XU Gui-Fang, SONG Lin-Lin, CHEN Hong-Zhi, HU Xi-Qiao, CHENG Yuan-Gang 6true 2015/12/15 11:19:56 1, MEI Zheng-Min¹, LUO Shi-Xing¹, XIAO Yuan-Hui¹, WANG Hong-Mei¹, LIAO Kui-Fu², OU Shan-Han^1*, ZHANG She-Nan¹]]> MAI Shi-Qiu¹, MEI Zheng-Min¹, LUO Shi-Xing¹, XIAO Yuan-Hui¹, WANG Hong-Mei¹, LIAO Kui-Fu², OU Shan-Han^1*, ZHANG She-Nan¹ 5true Ziziphus jujuba cv. Lingwuchangzao were studied by paraffin section techniques. The results were as foollows:(1)In slow growth period,the cell grown slowly,the exocarp was made up of 5 ～ 6 layers of cells. The epidermises cells constituted of one layer parenchyma cells and they were rectangular or elliptical. The parenchyma cells gradually increased inside the epidermis and formed sub-epidermal cells. The size of cavity appeared when the volume of fruit had been enlarging. The mesocarp had many vascular bundles;(2)The cells grew quickly in the first rapid growth period. The epidermis cells arranged looser. The increasing speed of cavity in the mesocarp was the fastest. The vascular bundles mainly existed in the mesocarp which was near the exocarp and endocarp;(3)The epidermises in step-down growth period were some rounded or elliptical cells and they became looser. The shape and volume of sub-epidermal cells were different and they arranged chaos. The size of cavity continued to increase and the vascular bundle became less and less in the mesocarp;(4)The exocarp cells reduced to 3～4 layers,epidermis cells and the sub-epidermal cells were difficult to distinguish in the second rapid growth period. The size of cavity gradually increased with the volume of fruit increasing,many cells singly arranged and became a net and finally formed a larger cavity. The number of vascular bundles were the least in the peel. In the course of Lingwuchangzao fruit development,whatever in different development stages or different locations,the morphological anatomical characteristics of fruit were dissimilar.]]> 2015/12/15 11:19:56 *]]> JING Hong-Xia, ZHANG Ying-Cai^* 4true 2015/12/15 11:19:56 1*, LUO Xu-Qiang¹, YANG Fan²]]> YANG Hong-Yan^1*, LUO Xu-Qiang¹, YANG Fan² 3true Camellia oleifera from Mingqiong platform were discussed. 213 loci were identified with 16 simple sequence repeat primers screened from 60 primers,out of which 203 loci were polymorphic and the percentage of polymorphic bands was 96.31%; 105 loci were identified with 8 oligonucleotide primers screened from 30 primers,out of which 94 loci were polymorphic and the percentage of polymorphic bands was 89.52%.

The results indicated that fertilization group and no fertilizer group showed significant differences in the terms of growth. The height and medicinal material field of fertilize K 30 g·m^-2 was 174.04 cm and 94.5 g,which was the highest among all the fertilize treatment group; The ground diameter of fertilization N 40 g·m^-2 was 16.79 mm which was the most coarsest. The combined application of N,P,K significant effected the yield of seed,when N,P,K reached 80 g·m^-2,80 g·m^-2and 30 g·m^-2,the seed yield was highest and the production rate reached to 179.30%; the highest schaftoside content could be reached 0.175% with being N at 40 g·m^-2,P at 80 g·m^-2and K at 80 g·m^-2. It could conclude that the reasonably fertilizing in complex treatment of N,P,K could promote the growth of D. styracifolium and increase the yield,also affected the accumulation of schaftoside. Take height,ground diameter,seed yield,medicinal yield and schaftoside content as evaluation standard. According to the fertilization mathematic model,the optimum fertilizer dosages of N was 42.4-64.5 g·m^-2,P: 49.5-59.0 g·m^-2,K: 30.0-41.0 g·m^-2. The optimum fertilization dosage ratio of N-P-K was 5.4:5.5:3.7.]]> 2015/12/15 10:55:21 *, TANG Xiao-Min, CHENG Xuan-Xuan, ZHANG Chun-Rong, PAN Hai-Yun]]> LU Ting, YANG Quan^*, TANG Xiao-Min, CHENG Xuan-Xuan, ZHANG Chun-Rong, PAN Hai-Yun 1true
