: This study was conducted to investigate the effect of atmosphere-leaf vapor pressure deficit (VPD) in Allium microdictyon Prokh. and Allium ochotense Prokh. The vapor pressure deficit (VPD) was rapidly increased with increasing temperature and decreasing relative humidity. Taken as a whole, the stomatal transpiration reaction was slightly late with increading of VPD. Maximum photosynthetic rate at high-VPD condition was 5.98 µmol CO 2 · m −2 · s −1 in Allium microdictyon, which was a little lower than 6.59 µmol CO 2 · m −2 · s −1 in Allium ochotense, respectively. After 2 p.m, stomatal transpiration of Allium microdictyon at the high VPD condition were rapidly decreased. Ci/Ca began to decline sharply at 8 a.m and showed the lowest value at 2 p.m, The results showed that Ci/Ca decreased with being used CO 2 in the mesophyll intercellular space for photosynthesis. In high VPD condition, The water potential values showed the highest at 5 a.m, and the lowest at 1 p.m in high VPD condition. The water saturation deficits (WSD) in high VPD condition showed about 1.5 times higher than in low VPD condition. The results indicated that physiological activities in Allium microdictyon is more limited from high VPD conditions.

: This study was carried out in order to survey the soil physico-chemical, morphology and content of saponins of 5 year-old Platycodon grandiflorum radix from different areas in Gyeongnam. Soil physical properties was showed 1.01-1.29 of bulk density of soil and soil hardness was increased with increasing soil depth, especially below the 30 ㎝, however it was maintained or small increased below the 40 ㎝. T-N and OM contents of top soil were highest at Geochang as 0.27% and 56.9 g/kg, respectively, compared to other areas. The root length was longer at Kimhea and Geochang as 33.8 and 33.7 ㎝, respectively, and fresh weight was heavy at Geochang as 208.5 g. The contents of saponin of P. grandiflorum radix was higher in fine root compare to main root. By region, content of saponins of P. grandiflorum radix were higher at Hapcheon than other area. Mg content was highly negatively correlated at p < 0.01 with platycodin D3, deapioplatycodin D, platycodin D, and deapioplatycodin D (-0.499**, -0.433**, -0.421**, -0.511** respectively). These results suggest that no-fertilized Mg effected on the improvement of saponin contents in P. grandiflorum.
