The results indicated the following: 1 All of the root, stem, leaf and bud of Ambrosia trifida have higher biosorption capability for Cu~(2+).

本论文获得的主要结论为： 1三裂叶豚草的根、茎、叶、花蕾四个部位对Cu~(2+)具有较强的吸附作用，且吸附能力的顺序为叶＞花蕾＞茎＞根。

Effects of explants,2,4-D,6-BA,NAA and AgNO3 on inducing buds were studied in pineapple(Ananas comosus cv.Hawaii) by using orthogonal design.

采用菠萝试管苗的叶片、叶鞘、茎段和茎薄片作外植体，以MS或1/2 MS为基本培养基，应用正交试验设计方法研究了不同浓度的2，4-D、6-BA、NAA和AgNO3对夏威夷菠萝不定芽的诱导效果，并在添加不同激素组合的培养基中进行芽的增殖和生根培养研究。

Basic fertilizer (organic fertilizer 500kg/667m2) add medium-term (organic fertilizer 500kg/667m2) facilitates favor to high-yield with the best conprehensive quality;density（40cm×60cm）with the highest yield; plastic mulching can significantly increase plant height, leaf width, leaf length, mature leaves, basal culm thickness, the first grade cormels weight and the second grade cormels weight; the first grade cormels of red sprout clocasia escalenta weight and yield had the obvious phenomenon of rapid growth in the medium expansion period of clocasia escalenta (July 14); an appropriate increase in plant height and stem yield was conducive to the increase in corn yield, the increase in corn yield favor to the first grade cormel numbers, the first grade cormel yield, the second grade cormel numbers, the second grade cormel yield, and thus obtain a higher yield.

基肥（有机肥500kg/667m2）+中期（有机肥500kg/667m2）有利于获得高产，综合品质最好；密度（40cm×60cm）产量最高；地膜覆盖可明显提高植株高度、叶宽、叶长、成叶数、茎基粗度、子芋和孙芋重量；红芽芋子芋重量和产量在芋膨大中期（7月14日）具有明显的快速增长现象；适当增加株高和茎叶产量有利于母芋产量的增加，母芋产量的增加有利于子芋个数、子芋产量、孙芋个数、孙芋产量的增加，从而获得较高的产量。

The results are as follows: the dwarf mutant A846 pertain to half-dwarf type, which height is about 38.64 cm on average, preponderating over the half-height of the wild-type, the elongation stage of the mutant represent dwarf character, internode elongation patterns of caulis are similarly the sh-type dwarf mutant, in which the first internode shows specific reduction, the elongation of these cells in the elongation zone immediately above the IM was dissimilar to the wild-type, longitudinal length of parenchyma cells were curtate, also the first internode exhibit markedly, which average is under the corresponding internode of the wild-type, the differentiation of the IM of each internodes of stem was similar to wild-type, as well as the number of internodes and the length of sheath of flag leaf.

结果表明：突变体A846平均株高38.64cm，大于野生型株高的一半，为半矮秆类型；其矮生性在拔节期显著表现；主茎茎秆各节间收缩比例不一，穗下第一节间显著缩短，与sh-型突变体类似；茎秆各节间居间分生组织细胞分化正常，由居间分生组织分化的细胞延伸受到不同程度的阻碍；各节间基本组织细胞纵向长度相应缩短，穗下第一节间缩短比例最大，其平均值小于野生型的一半；主茎节间数目与旗叶的叶鞘长类似于野生型。

Basal leaves decussate, middle stem leaves opposite, distal stem leaves alternate; inflorescence paniculiform with cymose branches

交互对生的基生叶，中间茎生叶对生，互生的上部茎生叶；花序圆锥花序状的具聚伞状的分枝 1b var。

Stems 18-100(-160) cm tall, well-branched above, densely gray villous on lower part, mixed above with short glandular hairs, often with raised lines decurrent from margins of petioles. Leaves subsessile or lower ones with petioles 1-3 mm; cauline blade lanceolate-elliptic to narrowly lanceolate or oblong-lanceolate, 3-12 × 0.5-2.5 cm, both surfaces villous, base usually rounded, margin denticulate with 15-60 teeth per side, apex subacute.

茎18-100(-160)厘米高，在上面的多分枝，叶近无柄或下部的具叶柄1-3毫米；茎生叶披针形椭圆的到狭披针形或者长圆状披针形， 3-12 * 0.5-2.5 两面，厘米具长柔毛，基部通常圆形，边缘具小齿具齿每边，近尖的先端。

This suggests that shoot apex is most sensitive to water stress and the ~(14)C-photoassimile distribution likely shifts from above-ground to root, being benefit to maintaining root growth and tolerance to water stress.

这表明茎尖对水分胁迫非常敏感，同化物向茎尖的运输受到抑制，运积重心由地上部转到地下部，从而有利于保持根系在胁迫条件下的生长，提高植物的抗旱性。

In order to screen out suitable lines for seashores in the east of China,lines of Spartin patens induced by low energy heavy ion were grown at simulating seashore environment condition.Leaf length and width,stem height and diameter,biomass and some photosynthetic indexes were assayed.
