[Method] With the healthy branches of potted Coleus blumei as experiment materials, effects of sucrose concentration on the rooting of Coleus blumei cuttings as well as effects of sunlight on its growth were studied. [Results] Being compared with the CK (clear water), sucrose solution with low or high concentration will not promote the rooting of Coleus blumei cuttings; illumination will enhance the growth of Coleus blumei cuttings with roots; cutting treatment and management measures will greatly influence the rooting rate of Coleus blumei cuttings. [Conclusions] Sucrose solution will not promote the rooting of Coleus blumei cuttings; illumination will enhance the growth of Coleus blumei cuttings.展开更多
This paper studied on the way of Coleus blumei, the leaf was chosen as explants and was inoculated on 1/2 MS medium with different combinations of 6-benzyladenine (6-BA), α-naphthaleneacetic acid (NAA) and indole...This paper studied on the way of Coleus blumei, the leaf was chosen as explants and was inoculated on 1/2 MS medium with different combinations of 6-benzyladenine (6-BA), α-naphthaleneacetic acid (NAA) and indole-3-butyric acid (IBA). The optimal conditions of callus induction from explants were achieved on the medium containing 6-BA (2.0 mg· L^-1) and NAA (1.0 mg· L^-1). Shoot tips were induced on the medium containing 6-BA (4.0 mg·L^-1) and NAA (0.5 mg·L^-1). The same media conditions were found suitable for shoot multiplication, we multiplied shoots rooted best on 1/2 MS medium supplemented with IBA (0.1 mg·L^-1).展开更多
