鸢尾为早春花卉，繁殖率较低。应用ＭＳ＋６－ＢＡ１～２ｍｇ／Ｌ＋ＩＢＡ０．５～１ｍｇ／Ｌ＋３％蔗糖适于茑尾花茎进行组织培养快速繁殖。但鸢尾品种间内源激素水平不一致，而影响分化的时间，德国茑尾从接种—分化需２０天，法国鸢尾需２５天，意大利茑尾和燕子花则需３０天以上。应用１／２ＭＳ＋ＩＢＡ０．５～１ｍｇ／Ｌ＋ＮＡＡ０．５～１ｍｇ／Ｌ＋１．５％蔗糖＋０．３％活性炭适于诱导生根，每株可诱导生根５～６根。采用蛭石后转入腐叶土：砂质土１∶１混合土移栽７５％～１００％成活。
Iris early spring flowers, reproduction rate is low. Application of MS + 6-BA1 ~ 2mg / L + IBA0.5 ~ 1mg / L + 3% sucrose is suitable for rapid growth of tissue culture of Cynanchum. However, the levels of endogenous hormones in iris varieties are not the same, but affect the time of differentiation, German tail tail from the need of inoculation - differentiation for 20 days, French iris need 25 days, Italian tail and swallowtail need more than 30 days. Application of 1 / 2MS + IBA0.5 ~ 1mg / L + NAA0.5 ~ 1mg / L +1.5% sucrose +0.3% activated carbon is suitable for inducing rooting and induces 5 ~ 6 rooting per plant. After the use of vermiculite into the leaf mold soil: sandy soil 1: 1 mixed soil transplanting 75% to 100% survive.
