초록
ATCC로 부터 구입한 11종(種)과 우리나라의 토양에서 분리 동정한 6종(種)의 Trichoderma를 실험(實驗) 재료(材料)로 하였다. 2% malt extract agar 배지(培地)에서 배양(培養)하면서 균사의 영양핵에서의 핵분열을 관찰하였다. 염색(染色)은 Giemsa staining solution으로 염색(染色)하였고 그들의 염색체(染色體) 수(數)를 세었다. 염색체의 형태(形態)는 다른 균류와 마찬가지로 점(點) 모양(dot-like)의 것이 대부분(大部分)이었다. 염색체(染色體)의 크기는 매우 작아서
The life cycle of 17 species of Trichoderma was elucidated to seize the proper stage for observing the nuclear behavior and chromosome count. The most convenient stage for the purpose in their life cycle was the stage just before producing the asexual spore. Of the 17 species in the genus Trichoderma the haploid chromosome numbers were counted 5,6,7 and 10. Six chromosomes were most frequently observed. It is believed that the basic chromosome number is placed between 4 and 10, and that the number might be 6, referring to the related papers. It appears necessary to reclassify the single genus of Trichoderma into at least two or three genera.
