在尼日利亚做了把菠萝冠芽切成4、6、8、12或16块繁殖菠萝幼苗,6个月后再把这些幼苗再切开繁殖。400克重的冠芽被切成4—12块的100％发芽,切成16块的60％发芽。切成4—6块的栽种6个月后,幼苗生物产量重400克(鲜重),比切成16块的苗增重更多,叶片更大,后者同期仅增重100克,且叶片更少、更小。从切开冠芽获得的小苗再切开增殖,不管每一株切成多少块,发芽 In Nigeria, pineapple root shoots were cut into 4, 6, 8, 12 or 16 pieces of pineapple seedlings, and these seedlings were cut again 6 months later. 400 grams of crown buds were cut into 4-12 pieces of 100% germinated, cut into 16 60% germination. After 6 to 6 months of planting, the seedling biomass was 400 g (fresh weight), more weight than the seedlings cut into 16, and the leaves were larger, with the latter gaining only 100 g over the same period Leaves smaller and smaller. Seedlings obtained from the cut crown crown and then cut the proliferation, no matter how many pieces of each cut into pieces, germination
