通过对菊花霞光四射、桃花线等2个品种的嫩梢、茎段、腋芽、叶片等不同营养器官的扦插试验,结果表明,各种营养器官作为插穗,扦插后都能生根,但生根的速度是不一致的。以嫩梢生根最快,在保湿的前提下,8~13 d开始生根,以下部茎段为最慢,约13~17 d开始生根,腋芽、叶片等因品种不同而生根的速度也不一样。因叶片扦插后,虽能生根,但移栽后只长根不长芽,直至冬季到来前逐渐枯死,所以不能作为繁殖材料。本试验针对采取插穗比较困难,或短时间内需要大量繁殖种苗的情况下,在生产上有一定的指导意义。 The results showed that all kinds of vegetative organs could be rooted after cuttage, but the rooting rate of rooting was higher than that of other vegetative organs, such as young shoots, stem segments, axillary buds and leaves. Speed ​​is inconsistent. The fastest rooting in young shoots, under the premise of moisturizing, began to root 8 ~ 13d, the lower part of the stems for the slowest, about 13 ~ 17d began to root, axillary buds, leaves and other varieties of different rooting speed is not the same . Due to the leaves after cutting, although rooting, but only after long-rooted shoots do not grow, until the winter before dawn, it can not be used as propagation material. This test for the more difficult to take cuttings, or a short period of time need to breed seedlings in large quantities, in the production of a certain significance.
