We made the survey to evaluate effects of practical experiences of environmental education using big tree in elementary school on teachers' perceptions. The survey was done at four elementary schools where a big tree was growing in the school grounds. We compared perceptions of teachers without practical experiences with perceptions of teachers with practical experiences. From the results obtained in this study, we understood that many teachers think of a big tree as local property and the imminent existence that always watches them, and had practiced the environmental education using imminent trees except the big tree. Therefore, we concluded that it was necessary to have some skills to affect the environmental education using trees, deepen a sense of closeness close to frequency to a big tree and find value widely for improvement of the practice will of teachers for the environmental education using the big tree. On the other hand, when there is not a big tree in school grounds, we understood that it was important that teachers practiced an environmental education using imminent trees. We thought that improvement of teachers' perceptions for the environmental education using trees and the knowledge is important.

The survey was conducted to evaluate the effect of environmental education, using big and tall trees in the period for integrated study in a lower secondary school, on the students' contact behavior with nature. In the month of May prior to the conduct of environmental education, the students were asked questions regarding their experiences of contact behavior with trees under several topics such as "climbing a tree" and "touching a bark." Thereafter, environmental education was conducted in the period for integrated study for a year. At the end of the learning, the same survey was conducted for both the students who selected the "Let's plant a tree nearby" course and those who did not, and the results were compared. Responses to the questionnaire showed that there was no significant difference between the students who chose the course and those who did not with regard to the frequency of contact behavior with nature, at the beginning of the learning. However, at the end of the learning, we discovered that those students who selected environmental education were more active in their contact behaviors than those who did not, which implicated that experimental study using big and tall trees would have a positive effect with regard to encouraging contact behavior with trees in everyday life.

We estimated the ability of aerial roots of Hedera helix 'Pittsburg' to adhere to the surface of 190mm-long wooden props with the cross section of 15mm X 15mm. On one side of the surface of a prop the 190mm-long ditch was made. The shape of the ditch was V-shaped (we called this type prop as V-prop) or rectangle (we called this type prop as R-prop). The width of the ditch in both V-prop and R-prop was 6mm or 9mm. For 84-85% of plants with V-prop, aerial roots grown toward the bottom of the V-shaped ditch, adhered to it and then extended longitudinally along it. And also for 68-74% of the p1ants with R-prop, aerial roots adhered to one of the L-shaped corners of a ditch and extended longitudinally along it. In some plants (9-23%) with either V-prop or R-prop aerial roots adhered to the flat surface of the lateral side or the bottom of the ditch and extended elliptically. These results showed that aerial roots prefer dark place such as the V-shaped valley or the L-shaped corners of a ditch, thus these results suggested the negative heliotropism of aerial roots of H. helix.

The effect of the supporting materials on the training of shoots in the production of potted Hedera helix cuttings was evaluated. Stalks made of Chamaechyparis obtusa woods with or without coconut-fiber mats (CMF) were used as supporting materials (props). The aerial roots adhered to the surfaces of props and radiated in all directions on them in the case where props without CFM (x-props) were used. On the other hand, aerial root extended to the surfaces of mats and penetrated into coconut fibers when props with CFM (y-props) were used. The ratio of rooted cuttings that adhered and climbed up to the top of the stalk was 33% when x-props were used, while about 70% in the case of y-props. In the case where no props were used, some shoots extended horizontally and twisted with the next shoot. In addition, some shoots with aerial roots touched the medium of other pots, and the roots grew into the medium. From these results, it is suggested that the use of props made of C. obtusa woods are useful in the production of potted H. helix cuttings.

In this study, we surveyed the actual conditions of facade greening with climbing plants for detached houses in Kyoto City. The percentage of detached houses with exterior space was 85% (N=222), and that of detached houses without exterior space was 15% (N=222). The scenes using facade greening were categorized into 4 types, street type, drive type, garage type, and water way type. We found out that the forms of facade greening were classified into 33 types. The typical cases were concrete block or brick wall combined with fence (N=40), concrete block or brick wall combined with gate (N=38), concrete block or brick wall (N=33), and wall surface of house (N=20). As a result of analyzing the combination of forms and scenes, the functions of the landscaping were considered to be an important role in street, drive, and garage. Analyzing the combination of the characteristics of using plants, scenes, and forms, we found out the various combinations of the properties of climbing plants and facade. The most important thing about this study is that facade greening was carried out at the various forms and scenes in detached houses.

A questionnaire survey was made for the dwellers of detached houses with 'facade greening' to know actual situation of such greening practice in Kyoto City. 79% of respondents said that they planned and made facade greening on purpose. Within respondents (N=94) for the control work, those who had sensed the work with the burden was as little as 21%. Though respondents who carried out facade greening without considering the street landscape was 52% (N=100), respondents who have received the good evaluation from the dwellers of neighborhood occupied 64% (N=100). The consciousness of the dwellers to the street landscape was low. However by positively tackling the operation and maintenance, it was proven that the dwellers had judged that facade greening contributes to the improvement in the street landscape.

We carried out landscape evaluation experiment by the semantic differential method using the roof panorama images to clarify how the difference of the landscape elements in the roof gardens and green roofs influence the psychology of people who use roofs. As a result of the factor analysis, the following 5 evaluation factors were understood as a landscape evaluation structure of roof gardens and green roofs : psychology, prospect bodily sensation, natural recognition, roof recognition and visual sense. Using the factor score, the effect of various landscape elements on the psychological evaluation of the roof users was examined. As a result, the psychological evaluation of the roof users rose, as the green regard rate increased (R=0.627, p=0.016) and as the building rate decreased (R=-0.707, p=0.005) in the roof panorama images.

Using the video images, we investigated the characteristic of landscape evaluation (LE) structure of different planting form of the roof. The planting form was classified from the field study of the green roof, 12 cases (roof garden (RG) of 5 cases, planting of single species (PS) using turf (T) and Sedum (S), and mixed planting (MP) of 6 cases, non-planting of 1 case) were extracted, and the LE experiment was carried out using evaluation grid method and semantic differential method. In the profile analysis, the psychological evaluation (PE) of the PS (S) was the lowest of the 12 cases. Meanwhile, the PE of the PS (T) was higher than that of the RG. In the RG, PS, and MP, in the factor analysis, the evaluation factors (EF) of body sensation and nature cognition were extracted. In addition to these two kinds of EF, the EF of vision was extracted in the RG.

We examined the effects of planting intervals and training methods on the growth of 3-years Stauntonia hexaphylla (Thunb.) Decne. seedlings covering fences of various mesh sizes with measuring ratios of covering fences. The differences of planting intervals and training methods affected the growth of seedlings. The average ratios of covering fences in close planting plot were larger than those in sparse planting plot. The average ratios of covering fences in vertical training plot were larger than those in horizontal training plot. The differences of mesh sizes affected the growth of seedlings. The average ratios of covering fences in small size of a mesh plot were larger than those in large size of a mesh plot.
