Abstract

Infection rates of pinhole disease in farmed Undaria pinnatifida (Harvey) Suringar were examined between November 2002 and April 2003 at an Undaria farm at Wando on the southwestern coast of Korea. The growth stages of U. pinnatifida can be defined as: a growth phase from December to the end of February, and a decay phase from March to April. There was a significant increase in the level of infection with pinhole disease (measured as the number of pinholes per cm2) between December and April (P < 0.01). Infection progressed from the upper part of the frond in December to the basal part in April. The infection rate of pinhole disease in relation to growth phase on farms over time is limited by the harvest of the seaweed crop at the end of the cultivation period in April. The midrib, sporophyll and stipe showed no signs of infection at any time during the cultivation period. The reduced physiological activity and tissue aging that occurred over time in the sporophytic life phase is the probable cause of the increasing infection rate of the disease.
