用ＧＬ生根剂（ＩＢＡ１０００ｍｇ／Ｌ＋粉锈宁１５０ｍｇ／Ｌ＋ＰＰ３３３２ｍｇ／Ｌ）５０ｍｇ／Ｌ浸泡扶桑插条基部２４小时，提高了插条的生根率、生根数、根干重，并扩大了生根范围。插条叶光合速率高于对照８２．８％，分配到叶的１４Ｃ－光合产物比对照少，而分配到茎和不定根的光合产物高于对照。插条叶和不定根中的可溶性糖、淀粉和纤维素含量低于对照，并随处理后天数的延长逐渐减少，木质素含量增加；茎和插条基部的可溶性糖含量高于对照，淀粉和木质素含量低于对照
The rooting rate, rooting number and root dry weight of Hibiscus mulberry cuttings were increased by immersing the base of Hibiscus mulberry with 50mg / L of IB rooting agent (IBA1000mg / L + triadimefon 150mg / L + PP3332mg / L) and enlarged the rooting range. The photosynthetic rate of cuttings was 82.8% higher than that of the control, and the 14C-photosynthetic products distributed to the leaves were less than those of the control, while the photosynthetic products distributed to the stems and adventitious roots were higher than those of the control. The contents of soluble sugar, starch and cellulose in cuttings and adventitious roots were lower than those in the control, and decreased with the prolongation of days after treatment. The content of lignin increased. The content of soluble sugar in stems and cuttings was higher than that in the control, starch and wood Su-content lower than the control
