Abstract
Water relations of Kalopanax pictus leaves obtained from the P-V curve. In the upper leaves of Kalopanax pictus seedlings, the original osmotic pressure at maximum turgor was -1.44 MPa, and the osmotic pressure at incipient plasmolysis point was -1.84 MPa, and the relative water content at incipient plasmolysis point was 78.2%.
P-V곡선에 의한 음나무 묘목 상층엽의 수분특성을 측정하였다. 음나무 잎의 최대팽압시의 삼투포텐셜은 -1.44 MPa 이었고, 초기원형질분리점의 삼투포텐셜은 -1.84 MPa, 초기원형질분리점의 상대함수율은 78.2%였다.
