벼 도열병의 역학적 연구 I. 단일병반으로부터 포자이탈량 조사

Epidemiological Studies of Rice Blast Disease Caused by Pyricularia oryzae Cavara I. Measurement of the Amount of Spores Released from a Single Lesion

자연상태하에서 잎도열병 병반으로부터 포자의 량을 측정하기 위하여 4종의 포자탐집기(금의 원형, 금의 개량형, 길야의 원형, 금$\cdot$길야의 개량형)를 검토한 결과, 원골한 포자형성 및 이탈, 포자채집, 검경에 있어서 한 두가지의 결점이 발견되었다. 따라서 위의 결점을 보완할 수 있는 새로운 포자채집기를 고찰, 성능을 검토하여 상기 4종의 채집기의 결점을 보충할 수 있는 결과를 얻었으므로 금후 자연상태하에서 포자이탈량 조사에 유용할 것으로 생각된다.

Four types of spore trap (Kim's original, improved Kim's original, Yoshino's original and mixed type of Kim's and Yoshino's original) were evaluated for their efficacy to "estimate the amount of spores released from leaf blast lesions under the natural conditions. It was found that all four types had one or two defects in allowance for adequate sporulation/release, spore catch or spore counting. Thus, an improved type of spore trap was devised considering that it could cover the defects mentioned above. As a result, newly developed spore trap was quite satisfactory in above mentioned aspects and it could be used for pursuit of spore release phase under the natural conditions.
