Understanding the surrounding plants (SP) by the high school students was compared with their abilities of intelligence (SI) and attitude (SA) in science education. 276 students attending 11 grade high school in the city of Incheon selected for this work were tested for SP and their abilities of SI and SA. The rates of SP were observed to be not related to the personal properties of student but to the abilities of total or science achievement scores made throughout school life. The abilities of SP were, by linear regression, calculated to be dependent upon the some components or variables of SI or of SA. Particularly, the abilities of SP were closely related to the abilities of picture matrix and vocabulary, but not to those of scientific logics among variables of SI. Also, the abilities of SP were calculated to be positively related those of scientific attitude, but negatively to science anxiety in SA. As based on this work, the SP was strongly suggested to be helpful for students `intelligences or for students` learning in their life.
Arbuscular 내생균근 균의 포트배양에 관한 연구
이상선,김명곤,엄안흠,이운학 한국균학회 1993 韓國菌學會誌 Vol.21 No.1
Four plants (Sorghum bicolor, Cassia mimosoides var. nomame, Sesamum indicum and Glycine soja) were cultivated at the pots including the soils containing arbuscular mycorrhizal fungi and were also investigated with the colonizations and productions of arbuscular mycorrhizal fungi. Whereas the colonizations of arbuscular mycorrhizal fungi continuously increased on the roots until 50 days, the productions of arbuscular mycorrhizal fungal spores were fluctuated with the terms of 30 days after inoculated. This indicated that the colonizations on the roots were not correlated with productions of arbuscular mycorrhizal fungal spores. Also, the various soils collected were applied to this technique by using pot cultures. Out of 82 various soils collected, the spore productions of arbuscular mycorrhiaze were observed only from the 42 soils. The spores cultured under artificial conditions were identified to 15 species with four genera. The spore productions of arbuscular mycorrhizal fungi using this technique would be considered to be related to the soil pH: The spore productions were found in the low pH for the species of Acaulospora and Glomus, the those near pH 7.6 for the species of some Glomus, Scutellospora and Gigaspora.
