对无花果地下部分形态学的观察表明：无花果地下部分可分为根与根茎；根茎部位易产生萌蘖，根茎扦插萌芽率达９６．２％；根段则无萌蘖发生。无花果品种间根茎扦插萌芽率差异显著，以“布兰瑞克”最高，达９０．０％；“绿抗１号”和“紫果１号”次之，分别为７５．６％和７０．７％；“玛斯义·陶芬”最低，仅４７．５％。以１ｍｇ／Ｌ和１０ｍｇ／Ｌ６－ＢＡ处理根茎，萌芽率分别为９０．０％和９０．３％，显著高于对照（清水处理）。不同浓度６－ＢＡ处理对根茎平均萌蘖数的影响差异不显著。同时，用０～１０ｍｇ／Ｌ６－ＢＡ处理根段，萌芽率均为０。对无花果根茎萌蘖解剖观察，发现萌蘖新枝源生于定芽而非不定芽。 Morphological observation of the underground part of the fig showed that the underground part of the fig can be divided into roots and rhizomes; rhizomes tend to sprout; the rate of germination of rhizomes reached 96.2%; There was significant difference in the rate of germination of figs among rhizomes in figs. The highest in Braunschweig reached 90.0%. The proportions of “Lancong 1” and “Zi Guo 1” were the second, 75.6% and 70 respectively. 7%; “Masi Yi Tao Fen” lowest, only 47.5%. The rhizomes treated with 1 mg / L and 10 mg / L 6-BA had the germination rates of 90.0% and 90.3%, respectively, which were significantly higher than those of the control (water treatment). The effects of different concentrations of 6-BA on the average number of rhizomes were not significant. At the same time, root segments were treated with 0 ~ 10 mg / L 6-BA, the germination rate was 0. On the fig rooting sprout anatomical observation, found that sprouting new branches originated in bud rather than adventitious buds.
