为了适应柑桔生产大发展的需要,中国农业科学院柑桔研究所组织培养组的同志们,遵照毛主席的“抓革命,促生产”的指示,顶住“四人帮”的干扰,为探索柑桔育种新途径,开展了柑桔植物组织培养的研究。他们于1977年10月首次成功地从柚子的胚乳培养出胚乳植株。植物种子中的胚乳是由三个单倍体(n)的核(即母本胚囊中两个极核和父本的一个精核)融合后分裂而成的三倍体组织。这种组织在离体条件下,通过人工培养分化产生的植株也是三倍体的,通称胚乳植株。这种胚乳植株以后可能结出无子的果实。又因胚乳也是受精产物之一,它的
In order to meet the needs of the great development of citrus production, the comrades of the tissue culture group of the Citrus Research Institute of the Chinese Academy of Agricultural Sciences abide by Chairman Mao’s instruction of “grasping the revolution and promoting production” to resist the interference of the “gang of four” Breeding new ways to carry out citrus plant tissue culture research. For the first time in October 1977, they successfully cultivated endosperm plants from endosperm of grapefruit. Endosperm in plant seeds is a triploid tissue that has been split by fusion of three haploid (n) nuclei (ie, two polar nuclei in a maternal embryo sac and a sperm nucleus of a male parent). This tissue in vitro conditions, through artificial differentiation of plants produced also triploid, commonly known as endosperm plants. This endosperm plant may later bear the childless fruit. Because the endosperm is also one of the fertilization products, it’s
