A FUNDAMENTAL STUDY OF "CONVENIENT CULTIVATION OF TEACHING MATERIALS FOR BIOLOGY EDUCATION".

(1)4种蓝藻(NIES19、NIES23、NIES24、IAMM6)可以在0.05%的Hyponex溶液中方便地培养。(2)由于环境的变化，毛状蓝藻在培养过程中发生了形态变化。这些结果表明蓝藻是教授固氮、生命周期和细胞分化的合适材料。(3)Volvox对经常用于微生物培养的矿泉水的性质有强烈的反应。这表明Volvox是水的锐利生物指示器，也是环境中教授水的合适材料。(4)我们对水中微生物的研究结果被记录在一本名为《水中微生物图解》的光盘中。(5)Kranz溶液中生长的拟南芥WS由于其生命周期的快速周转而适合于教学生命周期。(6)从Kranz溶液中生长的拟南芥Landsberg(Erecta)和拟南芥Columbia中收获了大量种子。在白光下生长的拟南芥比在白光下生长的拟南芥生长和衰老快。塞曼因其在人类活动影响下的坚持性、对人类生活的影响以及其吸引人的外形，适合于生态系统中的人类活动教学。

(1) 4 species of cyanobacteria (NIES19, NIES23, NIES24, IAMM6) were conveniently cultivated in 0.05% of Hyponex solution adjusted to pH 9 to pH11.(2) Morphological changes of cyanobacteria trichome were observed during cultivation due to their environmental change. These results indicate that cyanobacteria is suitable material for teaching N_2-fixation, life cycle and cell differentiation.(3) A sharp response of Volvox to nature of mineral water, used for cultivation of microorganisms frequently, was observed. This indicates Volvox is sharp biological indicator of water and suitable material for teaching water in environment.(4) Results obtained in our research about microorganisms in water were recorded in a CD-ROM entitled "Illustrated book of microorganisms in water.".(5) Arabidopsis thalianan WS grown in Kranz solution is suirable for teaching life cycle because of its rapid turnover of life cycle.(6) A lot of seeds were harvested from Arabidopsis thaliana Landsberg (erecta) and Arabidopsis thaliana Columbia grown in Kranz solution.(7) Due to ultraviolet irradiation, Arabidopsis grown under a labolight grew up and aged faster than that grown under a white light.(8) Araria elata (Miq.) Seeman is suitable material for teaching human activities in ecological system because of its perseverance under a condition affected by human activities, its influence on human life and its attractive shape.
