METHOD FOR CLONAL MICRO-PROPAGATION OF LILAC IN VITRO Russian patent published in 2012 - IPC A01G7/00 

FIELD: chemistry.

SUBSTANCE: invention relates to plant biotechnology. The method involves culturing single-node segments on a multiplication medium containing macro-, micronutrients, iron chelate, vitamins on the formula Murashige & Skoog (MS) or Quorin & Lepoivre, or Woody Plant Medium, or Driver & Kuniyuki, 30-40 g/l sucrose, 8-9 g/l agar-agar, 0.2-2.0 mg/l 6-benzylaminopurine and/or 0.2-2.0 mg/l zeatin, or 0.5-1.5 mg/l kinetin and antibiotics (penicillin (50-1000 mg/l) and/or ampicillin (50-1000 mg/l), and/or cefotaxime (50-1000 mg/l), and/or ticarcillin(10-500 mg/l), and/or streptomycin (5-500 mg/l), and/or tetracycline (10-1000 mg/l), and/or vancomycin (1-100 mg/l)). The obtained test-tube microplants are re-grafted onto the apical part and middle single-node segments. The single-node segments are re-grown on the multiplication medium and the apical parts are planted on a rooting medium. The medium contains 1/2 macronutrients, full micronutrients, iron chelate and vitamins on the formula MS, 10-30 g/l sucrose, 8-9 g/l agar-agar, above-listed antibiotics, 0.1 mg/l indolebutyric acid, as well as 0.01 mg/l α-naphthylacetic acid or 0.1 mg/l indoleacetic acid. Culturing is carried out on light-culturing racks illuminated with white fluorescent lamps with total intensity of 2000-4000 lx with a 16-hour photoperiod and temperature 21-25°C.

EFFECT: invention increases output of normally formed own-rooted microplants and improves growth and development of explants.
