Conventional paraffin sectioning was adopted to conduct anatomical examination of the nurse seed grafted Camellia oleifera union during development.Results showed that at day 4 after grafting,the nurse seed grafting union became the isolation layer;at day 8,the callus in the root stock was observed;at day 16,the callus was found in the scion;at day 22,the root stock connected the scion;at day 29,the nurse seed grafting union formed the vascular cambium;at day 35,vascular bundles was formed,which indicated that the nurse seed grafted seedling survived.Before induction of callus in the nurse seed grafted C.oleifera union,the primary organization structure of the stock accelerated growth and development,and gradually became similar to the structure of the scion.The cambium and other parenchyma cells in the grafted union could all be induced to produce callus,but the cambium was the principal source.

In this study,we measured three isoflavonoids in kudzu from eight populations in south-eastern United States.The concentrations of puerarin,daidzin and daidzein in the leaves were 0.0950 mg/g,0.698 mg/g and 0.110 mg/g,respectively.The concentration of daidzin and daidzein was significantly different among populations.During the growing season,three isoflavonoids in the leaves were higher in August than in July and September.The concentrations of the three isoflavonoids in the roots were 3.664 mg/g,1.0302 mg/g and 0.3689 mg/g,respectively.There were no significant differences in the three isoflavonoids among populations.Furthermore,the concentrations of the three isoflavonoids in kudzu from US populations were higher than those of Chinese populations,as reported in previous research.This study aimed to provide a theoretic and scientific basis for making full use of kudzu leaves,determining appropriate harvest times and the development and utilization of the puerarin leaves resource.

Based on field investigation,sample collection,and comprehensive analysis of the riparian vegetation in mountain rivers,the riparian flora characteristics were investigated.The results showed that 574vascular plants belonging to 390genera and 145families in the mountain rivers of the Jiulongjiang River headstream were identified,among which pteridophyte had 29families,54genera and 80species;gymnosperm had 6families,8genera and 10species;and,angiosperm had110families,328 genera and 484 species.Through comprehensive analysis several typical characteristics of the mountain river riparian vegetation(taking reaches of the Jiulongjiang River headstream as an example)were found as follows:(1)a rich floral composition,with the dominant families and genera highly prominent;monotypic,oligotypic and oligotaxic genera,and oligotypic and oligotaxic families formed a large proportion;(2)flora of ancient origin;rare and relict plants were abundant;and,(3)complicated geographical elements and flora connected extensively with most parts of the world fully reflected natural and human disturbance such as regional climate,topography and human activities.Results indicated that the riparian zone had an extremely important function in conserving regional biodiversity.

Effects of cadmium stress on seedlings growth and active ingredients in Salvia miltiorrhiza were investigated. Results showed that cadmium stress inhibited seedlings growth and increased Cd2+accumulation in both soil and seedlings. Moreover,both soluble protein content and membrane lipid peroxidation degree increased,while photosynthetic pigments content decreased under stress conditions. Compared with the control, in stressed S. miltiorrhiza leaves,the accumulation of six phenolic acid compounds showed different variant characteristics. Both caffeic acid and rosmarinic acid accumulation decreased significantly( p0. 05),while the content of protocatechuic acid increased( p0. 05),and the levels of tanshinol,protocatechuic aldehyde and salvianolic acid B decreased( p 0. 05). However, the accumulations of the phenolic acids components and four tanshinone ingredients all decreased in stressed roots, and the variances of rosmarinic acid, dihydrotanshinone, tanshinone Ⅰ and cryptotanshinone were significant( p 0. 05). Moreover,in the leaves of the stressed plant,the activities of PAL and TAT decreased significantly,but C4H and 4CL content increased significantly. These results showed that cadmium stress could reduce the production and quality of S. miltiorrhiza.

Taking formation as an index,the vegetation pattern diversity of Hubei Province was measured by affinity analysis.Results showed that mosaic diversity(m) of the Hubei Province vegetation landscape was 4.071,the landscape was complicated and there was no obvious ecological gradient.According to mean affinities(MA),the Hubei Province vegetation pattern was divided into three categories: the first central point category included vegetation from Wuhan City,Xiangyang City,Huanggang City and Suizhou City,which were typical,common,and played a key role in coupling patches in the whole vegetation pattern;the second outer point category included vegetation from Hefeng County,Lichuan City and Xianfeng County,which were rare,native and had important significance in composing the specificity and diversity of the whole landscape;the third middle point category included vegetation from Huangshi City,Jingzhou City,Jingmen City,and Yichang City(totally 14 administrative division units),which showed universality and rarity,were moderate,occupied more habitat space,and constituted the foundation of the whole vegetation pattern.Sorting mean similarity(MS) from central points to outer points showed that the similarity of adjacent regions was high.Northwest,Southeast and the Jianghan plain of Hubei formed the universality of the whole vegetation pattern;however Southwest Hubei constituted the specificity of the vegetation pattern.Large differences existed in the vegetation patterns between east and west Hubei Province,and the vegetation patterns were complicated.
