Abstract
溫度、相對濕度及露水三種因素之各種組合，其出現時間之長短，對葉稻熱病之傳染速率有顯著之影響；其影響程度，因組合而異。根據相關分析研判，適於傳染之溫度，在新竹地區為22~26℃；加入露水因素時，最適溫度為22~24℃；不加入露水因素時為24~26℃。嘉南地區最適溫度為24~28℃。
A study of the influence of dew, temperature and relative humidity on the extent of infection was determined by way of correlation analysis. Data used in this study were obtained in field at O-mei, Hsinchu and Pai-ho, Chiayi in1977.
In Hsinchu, the temperature range favorable for leaf blast infection was between 22 and 26℃, with an optimum at about 22-24℃ as dew factor was combined; and 24-26℃ when dew factor was not combined; whereas in Chiayi the optimal temperature ranged from 24-28℃, regardless of dew factor added or not added.
