Abstract
Cytological observations in the seven varieties of Juniperus chinensis L. showed three varieties (J. chinensis var. procumbens, J. chinensis var. kaizuka and J. chinensi.s var. aureo-variegata) were tetraploid with chromosome number, 2n=44, and rest of four varieties (J. chinensis var. horizontalis, J. chinensis var. sargentii, J. chinensis var. gtobosa and J. chinensis var. aureo-globosa) to be diploid, 2n=22. Chromosome configuration and behavior in the meiosis of P.M.C. of three tetraploids appeared to be slightly irregular. These results suggest that triploid tree can be artificially produced with these specific clones.
Juniperus chinensis 7변종(變種)의 세포학적(細胞學的) 특성(特性)을 조사한 결과 J. chinensis var. procumbens, J. chinensis var. kaizuka와 J. chinensis var. aureo-variegate는 2n=44인 tetraploid이고, 여타 4개변종(個變種)은 2n=22인 diploid이다. 이들 tetraploid 변종(變種)들은 기공(氣孔)이 2n에 비하여 18.4% 크고, meiosis시(時)의 염색체(染色體) 행동(行動)이 불규칙(不規則)한 핵판(核板)이 관찰되었다.
