荷花、睡莲根段繁殖试验
|
摘要
为了研究水生观赏植物的繁殖方法,对宝鸡植物园的荷花、睡莲进行了根段繁殖试验,结果表明:(1)根段繁殖与分株繁殖相比,繁殖植株数量多;与播种繁殖相比,生长快,经过幼苗阶段很快进入营养生长或生殖生长期。(2)荷花根段繁殖,当年可生出主藕、子藕、孙藕,当年成活株中70%可开花供观赏。而睡莲根段繁殖,当年能生根、发叶,但未形成供下次繁殖的地下茎,也未形成花器。
To find out the suitable reproduction methods, cutting root reproduction with Nelumbo SP. and Nymphaea tetragona Georgi was conducted. The result showed that: i) cutting root reproduction would produce much more plants, compared with plant-separation reproduction, and would have fast growth from seedling stage to vegetation or reproductive growth, compared with seed-sowing method; ii) Nelumbo SP. by cutting root reproduction would generate parent lotus root, offspring root and grand offspring root during current year, and 70% of survival plants will flower; whereas Nymphaea tetragona Georgi by cutting root reproduction would only have roots and leaves generated, no reproduction root and flowers formulated.
