菠萝一般用吸芽和裔芽进行营养繁殖。果实发育系单性结实,不自然结子。然而,如果在品种间进行异花授粉,就能大量结子。为了取得优良品质,在不同品种间进行了杂交。腋芽试管繁殖已获成功。在本试验中,主要是诱发杂种胚长出愈伤组织,接着分化成苗。 Pineapple generally buds and descendants nutrition breeding. Department of fruit development is uniparent, unnatural knot. However, if cross-pollination among breeds, lots of knots can be made. In order to achieve good quality, hybridization was carried out among different varieties. Axillary bud propagation has been successful. In this experiment, mainly induced hybrid embryos grow callus, and then differentiated into seedlings.
