It was observed that the influence of bud and its position on the healing process of grafting unions using hardwood sectioning method, and found that:(1) bud of a scion and its position to the graft unions have no influence on callusing formation of the isolation layers, and the early differentiation of cambia;(2) a scion bud closer to the grafting union would promote the formation of more compacted callus cells and the earlier formation of callus bridges;(3) conduit differentiation in grafting unions of lower-bud scions was later than that of other treatments.

利用滑动切片法对芽子有无及芽位对嫁接愈合过程的影响进行了观察，发现：(1)接芽有无及芽位对隔离层及愈伤组织形成和形成层的早期分化没有影响；(2)芽或去芽的芽位距接口近，可以促进愈伤组织的紧密连接，即愈伤组织桥的形成；(3)低位芽枝嫁接体中导管分化较晚，而其它处理导管的分化几乎是同时发生的，而且导管首先出现于愈伤组织薄壁细胞中。

0Mg/L 6-benzylaminopurine was the optimal concentration of shoots quantity inducing which frequency of inducing shoots and number of shoots per explant were 100% and 11.1 respectively. 0.5mg/L 6-benzylaminopurine was the optimal concentration of shoots length inducing which average length of shoots was 12.0mm. Explant size had significantly effects on direct shoots quantity and length induction. When complete cotyledon used as explant, frequency of inducing shoots, number of shoots per explant and average length of shoots could approach to 100%, 6.7 and 17.1mm respectively. 2.0mg/L silver nitrate could significantly increase shoot quantity induction, both frequency of inducing shoots and number of shoots per explant could be as high as 97.2% and 4.2 respectively. But silver nitrate also could restrain shoots elongation.

结果表明：不同黄瓜品种直接不定芽数量诱导存在显著差异，但长度诱导无显著差异；6-苄氨基嘌呤对直接不定芽数量和长度的诱导作用显著，其中4.0mg/L为数量诱导适宜浓度，其出芽率和每外植体出芽数达到最高，分别为100.0%和11.1，0.5mg/L为长度诱导适宜浓度，其平均芽长12.0mm；外植体的大小对直接不定芽数量和长度均具显著影响，随着子叶的增大诱导直接不定芽的数量和长度增加，其中单片完整子叶为最适宜大小，其出芽率、每外植体出芽数和平均芽长分别达到100%、6.7和17.1mm；硝酸银也对直接不定芽数量诱导影响显著，其中2.0mg/L为适宜浓度，出芽率和每外植体出芽数分别达到97.2%和4.2，但对芽长有抑制作用。

Beach stone tablet of tea produced in Hunan Wulingshan Yuanshui River Beach stone tablet of Yuanling mountains, which rise amid挺秀here, trees green, vertical and horizontal streams, cloud-filled, abundant natural conditions, the growth of strong tea,芽头fat, leaf quality of soft, downy a lot of unique quality.

And then adding NAA at low concentration in MS was used to give rise to roots. We also found that lower level of hormone could control effectively browninng and vitrifaction during the culture and G1 n (6mg/L) and AgNOj (2mg/L) supplemented in shoot induction media could improve the shoot information rates apparently (about90%).The whole period of plant regeneration from leaflets of peanut could be divided as five steps: germination - shoot induction -shoot elongation-rooting- tranplant.

用1／2MS培养基萌发花生种子，9-10d后，从无菌花生苗上切取幼嫩叶片中部为外植体。2500Lux光照和27±1℃条件下，在诱芽培养基(MS+BA3mg／L+NAA0.8mg／L+AgNO_32mg／L十Gln 6mg／L)培养12-14d即可观察到明显芽点或瘤状突起，较前人报道的培养时间大大缩短了，4w后芽点进一步发育成丛生芽，芽诱导率达90.2％，每个外植体平均产9个丛尘芽，然后转至培养基MS+BA3 mg／L+AgNO_32 mg／L上诱导芽的伸长，3-4w后可长至3-4cm，切下带有2-3片叶片的幼芽移至生根培养基(MS+NAA0.8mg／L+AgNO_32mg／L)，1w后切口处可见白色不定根形成。

The single-celled phytoplankton included 116 inshore wide distribution species, 31 inshore warm-water species and 26 inshore temperate species, and the vascular plants were of 6 ecological groups, i.e., halophtes (24 species), hydrophtes (22 species), amphiphytes (35 species ), mesopllytes (103 species), zerophytes (6 species), and psammons (4 species). Halophtes, hydrophtes, and amphiphytes were the edificators and dominants, reflecting the azonal feature of the wetland vegetations. The vascular plants were divided into 5 life-forms, including 20 phaenerophytes, 4 chamaephytes, 54 hemicryptophytes, 48 geophytes and 68 therophytes, among which, hemicryptophytes and geophytes accounted for 52.58%, reflecting the relatively important function of cold and wet climate and local water-accumulated bottomland environment on the vascular flora formation.

区系中的单细胞浮游藻类包括近岸广布种116种、近岸暖水种31种、近岸温带种26种；维管束植物被划分为6大生态类群，包括盐生植物24种、水生植物22种、湿生植物35种、中生植物103种、旱生植物6种、沙生植物4种，保护区内湿地植被的建群种、优势种均为水生植物、湿生植物或盐生植物，反映了湿地植被的隐域性；维管束植物按照生活型划分，有20种高位芽植物、4种地上芽植物、54种地面芽植物、48种地下芽植物和68种1年生植物，其中地面芽植物、地下芽植物占区系植物总种数的比例较高，占52.58%，反映冷湿气候和局部低洼积水环境对区系的形成起较重要作用。

Considering the bud of Platycarya longipesas basic unit of modular population,the bud population structure of sample trees, which were 8-12 years old and located at different places on slope in karst area in the middle of Guizhou province, was studied.

以圆果化香植株的芽为基本构件单元，对贵州中部喀斯特山地不同坡位上8-12年生植株的芽种群结构进行研究，结果表明：圆果化香芽种群芽总量分配随枝级发生变化，芽数量最多的枝级为树冠中间部位的二级或三级枝，树冠表层的末生枝和紧靠树干的一级枝芽数量较少。

Based on the revised system,the vine life form spectrum analysis shows that the phanerophyte lianes are absolutely dominant,accounted for 72.7% of all vines,followed by the geocryptophyte vines(17.5%),the hemicryptophyte vines(6.2%),the therophyte vines(2.7%)and the chamaephyte vines(1.5%).

对本区生活型分析的结果表明，中国亚热带东部藤本植物的生活型谱是以高位芽藤本占绝对优势( 72 。7%)其次为地下芽藤本( 1 7.5%)、地面芽藤本( 6.2 %)、1年生藤本( 2 。7%)和地上芽藤本( 1 。5%)，除地下芽藤本比例略高外，与亚热带常绿阔叶林生活型谱十分接近，具有比较明确的生态学意义；地下芽藤本比例略高的原因可能是由于该类藤本具有地下贮藏器官，因此有利于次年春天迅速的抽生攀援枝，较其他草质藤本更优先占领光合空间，这是对区域小生境长期适应的结果。

The results show that: double and heavy machine-plucking increase bud density and one-leaf and one-bud yield in autumn. They also remarkably decrease bud weight, length and fitting ratio for processing of Bailumaojian tea. Among the 4 treatments, light machine-plucking has the largest one-leaf and one-bud yield fitting for processing famous Bailumaojian tea. Chemical analysis shows that leaves of four treatments are all fit for processing famous Bailumaojian tea, while those of no machine-plucking treatment have the best organoleptic quality.

结果表明：2次机采和重度机采处理显著增加秋季茶芽密度和1芽1叶初展鲜叶产量，显著降低单个芽头的平均重量、长度及符合加工白露毛尖茶芽大小标准的茶芽合格率；符合加工白露毛尖茶芽大小标准的1芽1叶初展鲜叶产量轻度机采处理最高；内含成分分析表明，4个处理秋季1芽1叶初展鲜叶均适宜加工白露毛尖茶，以不机采对照处理感官品质最好。
