In plants, vivipary occurs when seeds or embryos begin to develop before they detach from the parent. Plants such as some Iridaceae and Agavoideae grow cormlets in the axils of their inflorescences. These fall and in favourable circumstances they have effectively a whole season's start over fallen seeds. Similarly, some Crassulaceae, such as Bryophyllum, develop and drop plantlets from notches in their leaves, ready to grow. Such production of embryos from somatic tissues is asexual vegetative reproduction that amounts to cloning.

  • في النباتات، تحدث الولادية (بالإنجليزية: Vivipary) عندما تبدأ البذور أو الأجنة بالتطوير قبل أن تنفصل عن الأم. وفي بعض النباتات تتطور وتسقط نباتات صغيرة من الشقوق في أوراقها، وتكون جاهزة للنمو. إنتاج الأجنة من الأنسجة الجسدية هو التكاثر الخضري اللاجنسي الذي يرقى إلى الاستنساخ. (ar)
  • Pada tumbuhan, vivipari merupakan fenomena ketika benih atau bibit mulai berkembang sebelum terlepas dari induknya. Selanjutnya bibit tumbuh, terlepas dari buah dan akhirnya tersebar. Tumbuhan seperti Iridaceae dan Agavoideae benihnya tumbuh di axils perbungaannya. Musim gugur merupakan waktu tanaman ini berkembang biak secara efektif. Demikian pula, beberapa Crassulaceae, seperti Bryophyllum, benihnya berkembang dan planletnya jatuh dari takik di daunnya, dan siap tumbuh. Produksi embrio dari jaringan somatik seperti itu adalah reproduksi vegetatif aseksual yang menghasilkan kloning . (in)

  • 胎生植物(Viviparous plants)又称 胎萌植物,是指果实成熟后不脱离母体植物,种子仍留在果实中并不掉落,而会在果实内直接发芽长成幼苗;即幼苗在母株上发育后才脱落、着生进而独立生长。 红树科的胎生,首先是胎生根(viviparous root)突破种皮及果皮,接着胚轴变粗而与胎生根形成棒状物,子叶仍留在种子内吸取母体养分;胚芽可从果实中钻出来并在母树上长成幼苗。当小树长到约20-30厘米左右高时,就自动落到海滩泥地里,然后生出根来,如果落下正落到水面上不能插入泥土,它会随海浪漂流,一旦遇到泥土,它就照样能扎下根,生长发育。 红树林是一類稀有的木本胎生植物。 (zh)
