| 摘 要： | 以罗汉果试管苗为试材进行不同生根方式的比较试验,并对其生根过程进行形态解剖学观察。结果表明:罗汉果试管苗茎段基部不定根起源于韧皮部与束中形成层交叉的部位,节部不定根主要起源于髓射线与束间形成层交叉的部位,属于内起源。节部不定根靠近叶隙,也与叶迹有关,根原基形成早。节部比节间生根早、根多,根分布结构好。

| Abstract: | In this experiment the in vitro plantlets were used as materials for studying the effects of rooting ways on rooting and further anatomical observation of rooting in Siraifia grosvenorii.The results indicated that the adventitious roots of the base of the stem originated from the cross region of phloem and fascicular cambium;and the adventitious roots of the burl originated from the cross region of pith rays and interfascicular cambium,which belonged to inner origin.The adventitious roots of the burl formed close to leaf gap and also beared on leaf trace.The root primordia formed early.Rooting in the burl was earlier than in the parel,so did the number of rooting.The distribution of root system was well in structure. |
