Plant stem cutting are commonly used for vegetative propagation, and it can be used to obtain equal bio-types of Veronica dahurica Steven and the rare species Veronica pusanensis Y.N.Lee. Here, we compared the effects of three concentrations of indole-3-butyric acid (IBA) and α-naphthalene acetic acid (NAA) on the cuttings of V. dahurica and V. pusanensis. The effect of IBA treatment on the root quality of V. dahurica and V. pusanensis was more than that of NAA; moreover, the number of adventitious roots was significantly improved by 1.5 and 0.5 mg L⁻¹ IBA (59.00 and 46.85, respectively). In addition, the root length of V. dahurica treated with 1.5 mg L⁻¹ IBA (15.20 cm) and callus formation percentage of V. pusanensis treated with 1.0 mg L⁻¹ IBA (2.22%) were significantly improved. We suggest that the use of IBA may be beneficial for vegetative propagation of the V. dahurica and V. pusanensis cuttings.

植物的cutting插通常用于无性繁殖，可用于获得Veronica dahurica Steven和稀有物种Veronica pusanensis YNLee的相同生物型。这里，我们比较了吲哚-3-丁酸（IBA）和上的钻屑α萘乙酸（NAA）的三个浓度的影响V.白芷和V. pusanensis。IBA处理对根质量的影响V.白芷和V. pusanensis超过该NAA的; 此外，不定根的根数显着提高了1.5和0.5 mg L ^-1 IBA（分别为59.00和46.85）。另外，V。dahurica的根长用1.5 mg L ^-1 IBA（15.20 cm）处理的小鼠和用1.0 mg L ^-1 IBA（2.22％）处理的釜山葡萄的愈伤组织形成百分比显着提高。我们建议，IBA的使用可能有利于V. dahurica和V. pusanensis插条的无性繁殖。
