(一) 菠萝是采用无性繁殖的。菠萝的无性繁殖体有六种,即:(1)冠芽,(2)裔芽,(3)冠裔芽,(4)吸裔芽,(5)吸芽,(6)蘖芽。有刺的菠萝品种如菲律宾种和台湾种等通常用吸芽繁殖;而无刺的菠萝品种如沙拉越种和夏威夷种等则常用冠芽与裔芽繁殖。我们在多年的生产实践中,发现沙拉越种冠芽和裔芽的后代,变异性很大,品种严重退化,畸形芽与畸形果越来越多,叶缘多刺,果小而质差。
(A) pineapple is the use of asexual reproduction. There are six kinds of asexual propagules of pineapple, namely: (1) crown buds, (2) buds, (3) crown buds, (4) suction buds, (5) suction buds, and (6) tiller buds. Barbed pineapple varieties such as Filipino and Taiwan species are usually sprouted by suction buds; while unripe pineapple varieties such as salads and Hawaii species often use crown and descendants of reproduction. In many years of production practice, we found that saplings of more kinds of crown buds and descendants of descendants, great variability, serious degenerative varieties, abnormal buds and deformed fruit more and more, leaf edge prickly, fruit small and poor quality.
