近十多年来植物体细胞融合的研究取得一些进展,先后在烟草、矮牵牛、胡罗卜、蕃茄等几个属的植物上获得种间和属间体细胞杂种植株。在国内自1980年以来也获得烟草种间和属间体细胞杂种植株。但是无论国际、国内对体细胞杂种植株的观察多只停留在外形观察和体细胞染色体的计数上。对体细胞杂种植株的细胞学观察却极少报导。体细胞杂种与有性杂种有否异同?同育性有关的减数分裂情况如何等都不清楚。我们用本所80年获得
Some advances have been made in the research of somatic cell fusion in recent ten years. Interspecific and intergeneric somatic hybrid plants have been obtained successively in plants of several genera, such as tobacco, petunia, carrot and tomato. Tobacco interspecific and intergeneric somatic cell hybrid plants have also been obtained in China since 1980. However, regardless of international and domestic observation of somatic hybrid plants mostly stay in shape observation and somatic chromosome counts. Cytological observations of somatic hybrid plants are seldom reported. Is there any difference between somatic hybrids and sexual hybrids? How are meiosis related to fertility? We use our own 80 years
