This study was carried out to investigate the characteristics and infection effects of AMF with soil samples collected at some sites in Gyeonggi province, Korea. AMF spore and characteristics of infection structure in upland plant root were observed as wet sieving and staining method, growth of Capsicicum annum was compared between treatment and non treatment. AMF spores isolated from each soil sample were ellipse or circle type and the colors were soft yellow and white. The colonization rate of AMF with soil infection of Zea mays roots was 13.3~83.3%, the rate of infected soil collected from Z. mays was higher on average. When compared to the growth of C. Annum with control after infection on C. annum, it wasn't showing many differences in fresh weight, dry weight and height, but the yield of fruit of C. annuum showed double than the control group.

With increasing the demand of urban greenery, market of landscape trees using container has grown steadily. However, there has been little research on the proper fertilizer application for various landscape trees using container. This study was conducted to investigate optimal fertilizer intensity for Crataegus pinnatifida to produce landscape trees using container. The main objective of this study was to examine effects of fertilization treatments (Con., 0.5, 1.0, 2.0 g/L) on the growth characteristics of Crataegus pinnatifida. In this study, Crataegus pinnatifida showed the highest growth of tree height (TH), root collar diameter (RCD), dry biomass weight (DBW) and Seedling Quality Index (SQI) in 1.0 g･L-1 treatment (p<.05). Especially, 1.0 g･L-1 treatment showed 4 to 9 times better quality than other treatments in SQI. In the case of height/root collar diameter (H/D) ratio and top/root (T/R) ratio, there were no significant differences between the treatments (p>.05). Soil-plant analysis development (SPAD) value on 2.0 g･L-1 treatment was much higher than that on other treatments (p<.05), but 2.0 g･L-1 treatment showed lower value than 1.0 g･L-1 treatment in the growth of TH, RCD, DBW and SQI. Therefore, our results support that 1.0 g･L-1 could be more economical and environmental than 2.0 g･L-1 , which is the highest fertilizer intensity on Crataegus pinnatifida's container production.
