During the early period of growing season, the increase rate of Salviae miltiorrhizae root weight was the highest, and it appeared the lowest at the end of growing season.

通过砂培试验研究了铜、锌对丹参根重，丹参根中3种丹参酮的含量及其累积量的影响以及铜、锌在丹参体内的迁移与分布规律。

The morphology of M2 and M3 was observed in hothouse and mutants on cotyledon and root of seedling, or embryo of seed were identified. The result showed that there were 8 types of mutative treats on cotyledon, including light-yellow cotyledon, yellowish cotyledon, trump-shaped cotyledon, multilobed cotyledon, non-cotyledon, single-cotyledon, tricotyledon and quadrcotyledon.

M_2和M_3的水培和形态学观察的结果发现，子叶性状出现浅色、黄化、喇叭形、多耳突、无子叶、单子叶、三子叶、四子叶等8种变异类型；根系性状出现短小根、发达根、无侧根和弱向地性等4种变异类型；种胚性状中发现了多胚变异。

常世民，韩培彦，邢汝东，等。cortisomol根管糊剂根充术后反应的近期疗效观察［j］。

Diospyros kaki Thunb cv.Fuyu and Jiro are Japanese persimmon varieties. Dormant buds taken from persimmon trees, as in vitro explants materials, were set up successfully. New shoots were attained. Callus was induced and adventitious buds were differentiated from leaves and roots of tissue cultures; new shoots propagation and shoots rooting were studied in different basal medium added different hormones.

本研究以甜柿品种富有柿与次郎柿为材料，系统地研究了两品种的组培快繁、组培苗叶片和根段的不定芽再生、愈伤组织的诱导和不定芽的分化、不定根的诱导等技术，以期为柿果的转基因技术奠定基础，同时也为富有柿与次郎柿苗木的快速繁殖提供技术依据。

Two Elsholtzia haichouensis Sun populations, one from Cu mine sites and the other from uncontaminated sites in Hubei province, were investigated in hydroponic experiments for the differences of Cu accumulation and ecophysiological responses to Cu under Cu treatment.

以海州香薷铜矿区种群和非矿区种群为对象，通过水培实验，比较分析了两个种群根中铜的吸收、MDA含量、根伤流液量和酸性磷酸酶活性变化的差异。

With the increase in Cu concentration in the solutions of the water culture, the plant height, biomass of the overground part, root length and weight of the vegetables decreased.

在水培条件下，随着铜添加浓度的升高，各蔬菜的株高、地上部生物量、根长和根重均逐渐降低。

The results showed that: 1 under the hydroponic culture established in this research, the experimental wheat plants grew well andperformed the typical architecture responses when exposed in Pi deprivation. Hemi-qantitative RT-PCR revealed that the transcriptional level of known P response gene changed dramatically; 2 In general the length of wheat root axis and the root/ shoot ratio arose when the Pi supply was deprived, however, the change models differed among different wheat genotypes. The investigation on their molecular basis would offer the useful clue for seeking high phosphorus efficiency protoplasma and gene resources of wheat.

结果表明：1在研究建立的小麦水培体系中，小麦植株生长正常并对磷饥饿胁迫条件做出发育形态建成水平的反应；半定量RT-PCR分析显示在此体系中小麦磷响应基因也在转录水平上产生显著变化；2在水培条件下不同基因型小麦对磷饥饿胁迫的反应总体上表现在根轴长度和根冠比有所提高，但不同基因型小麦的反应特点有差异；对这些反应特征的分子机理的深入分析可为有效筛选磷高效小麦新种质以及发掘磷高效基因资源提供线索。
