Under conventional culture conditions ((25±3)℃, relative humidity 60%-70%, 1500-2000 lx for 10-12 h/d), aseptic buds or leaves from the plants of Aloe vera var. chinensis, Pelargonium citrosum vanleenii and triploid Populus tomentosa were respectively used to research the technology of proliferation and rooting integration. The results showed that: after 50 d when aseptic buds of Aloe vera var. chinensis were transferred in MS + 6-BA 2.0 mg/L+ NAA 0.1 mg/L+ AC 0.1%, the average number of differentiated buds reached 3.4 and the rooting rate reached 100% with 6.1 roots which were sturdy, long and yellow-white and 52.0 cm length of all roots per plant. After 45 d transferred in MS + 6-BA 3.0 mg/L + NAA 0.2 mg/L + AC 0.05%, aseptic buds of Pelargonium citrosum vanleenii proliferated most fastest with the average number of differentiated buds reaching 10.2, and the rooting rate amounted to 100% with dark-green leaves. After 55 d when aseptic leaves of triploid Populus tomentosa were transferred in MS + 6-BA 0.5 mg/L + KT 0.4 mg/L + NAA 0.2 mg/L + Ad 25.0 mg/L + AC 0.05%, differentiated buds arrived at an average of 8.6 and the rooting rate achieved 92% with more and longer, light-white roots.
