地被菊花粉萌发及花粉活力的研究

用ME的盐类和维生素附加16％聚乙二醇4000(PEG4000)和15％蔗糖对野菊及新红、塞旗红、玫瑰红的花粉进行培养。结果表明，萌发率分别为80．2％、85．3％、61．3％和46．5％。PE‰对菊花萌发有明显促进作用。但庶糖的作用不能被PEG所取代。菊花花粉萌发较合适的温度为10-20℃，在4-8℃时，萌发率及速度迅速降低，35℃萌发虽快。但花粉管短且破裂。在4℃条件下花粉可贮藏4-14d。但不宜干燥贮藏。

High frequency embryogenic callus induction and plant regeneration from mature caryposis of big bluestem and little bluestem

Big bluestem (Andropogon gerardii Vitman) and little bluestem [Schizachyrium scoparium (Michaux) Nash.] are native to the North America and are important forage grasses and ornamental grasses. Both grasses are proposed as ideal biomass producers for cellulosic ethanol production. To apply genetic transformation, which is an important tool for incorporating desirable agronomic traits into plants to both species, however requires an efficient and reproducible regeneration protocol. We used mature caryopses from big and little bluestem as explants and tested the effect of various combinations of 2, 4-dichlorophenoxyacetic acid (2, 4-D) (1, 2, 3, 4 or 5 mg l⁻¹) and kinetin (KT) (0, 0.1 or 0.2 mg l⁻¹) on embryogenic callus induction with LS as the basal medium. The highest percentage of embryogenic calli induction occurred on medium containing 2, 4-D alone at 2 mg l⁻¹ for ‘Bison’ and on medium containing 4 mg l⁻¹ 2, 4-D alone for ‘Bonilla’ big bluestem. For little bluestem, the highest percentage of embryogenic callus induction occurred on medium containing 3 mg l⁻¹ 2, 4-D plus 0.1 mg l⁻¹ kinetin, suggesting that addition of KT is beneficial. Shoot regeneration took place on LS basal medium without any plant growth regulator for both species, although the addition of KT increased both regeneration frequency and the number of shoots produced per callus. Rooting of shoots reaching about 2 cm long occurred readily with or without α-naphthaleneacetic acid (NAA). Rooted plantlets were all successfully established in the soil.     

中日森林文化比较研究及启示

日本是一个森林大国，拥有着丰富的森林资源和森林文化，其教训和经验对中国乃至全世界的后工业化国家都有着很大的启发和借鉴意义。对日本的森林状况进行回顾和评价，从其森林思想中汲取精华，不断挖掘森林文化所蕴藏的丰富含义，恢复和弘扬森林文化，这对中国正在开展的生态文明建设以及解决环境问题都能提供思考和帮助。

影响番茄离体培养再生的主要因素探讨

以5个番茄品种的子叶和下胚轴为外植体,对无菌苗的生理状态、激素组合、激素浓度和基因型等影响组培效果的主要因素进行探讨,建立了番茄的高效离体培养再生体系。结果表明,下胚轴和子叶均得到了高达100%的出愈率和95%以上的分化率;最佳的品种是T431;最佳激素组合为ZT1.0mg·L-1和IAA1.0mg·L-1。     

Effects of Three Drugs on Membrane Metabolism Against Cysticerci cellulosae in vitro

To investigate the effects and mechanisms of the benzimidazole carbamate and benmidine drugs on Cysticerci cellulosae and choose effective drugs on Cysticerci cellulosae, the membrane metabolism of Cysticerci cellulosae in vitro was tested after three kinds of drugs which were used respectively. The indexes included the contents of lipids, the contents of SA and the changes of the membrane fluidity. The results showed that oxfendazole could inhibit the membrane metabolism of immature and mature Cysticerci cellulosae in vitro, and albendazole only inhibited the mature one, while thibendimidine neither acted on the immature nor mature one.
