영문 초록

The growth characters influencing the lodging degrees were examined in 10 cultivars of soybean under dense spacing and heavy dressing. Among major growth characters of soybean which related to lodging, plant height, number of branch and LAI were correlated positively to lodging and stem diameter and root dry weight were correlated negatively to lodging. The dominant factors related to lodging analyzed by path coefficient were number of branch and LAI, which were closely related to the decrease of light penetration into the canopy. Also the light penetration rate showed significant negative correlation with lodging degree, suggesting that the main factor of lodging under dense spacing and heavy dressing whould be the decrease of light penetration into soybean canopy.
