The teaching materials for plant sciences should be efficient and convenient, providing maximum information with minimal requirements for labour, facilities and expenditures. A tachyplant, Arabidopsis thaliana (L) Heynh. (Cruciferae) may meet above qualifications; its short life-cycle, its small size and therefore its ability to grow large populations under laboratory conditions and to grow normally on the artificial media, its fecundity of seeds, its low chromosome number (2n=10), and the existence of numerous mutant strains. In the present study, we have examined the capacity and efficiency of this plant for teaching the plant life-cycle, various developmental phenomena through its process and its regulation by environment in the courses on experimental botany. In this article we will describet he simplest method of the aseptic culture in a test tube, and demonstrate some experiments (effects on growth and development of nutrients, light, temperature and gibberellin, a plant hormone) practicable in classroom.
