摘要
A serial study on differential response in absorption and translocation of 14C-oxyfluorfen was conducted by use of a group of selected rice cultivars as the tolerant or the susceptible to oxyflourfen. 1. Differential response in absorption and translocation of selected cultivar group. The susceptible cultivar group has reached as higher rate as 209%, 193%, 344%, 204% and 152% of the tolerant cultivar group in root absorption rate per unit dry weight, lower-shoot absorption rate, higher shoot absorption rate, whole amount of absorption, and the rate of translocation from bottom to shoot, respectively. 2. Differential response in absorbtion and translocation of selected cultivar as affected by exposed portion and time. Regardless of cultivar, the rate of root absorption has effectively realized but the translocation was significantly limited. Lower portion of shoot has also achieved a higher amount of absorption but the translocation was very limted. By relaying the exposure time, the amount of root absorption was increasing, and persistent absorption was rather effective in the susceptible (cv. Mushakdanti) cultivar than the tolerant (cv. Chonkoto). Translocation of oxyfluorfen from shoot to root was tended to easily attaining in both cultivars
