Materials and methods
Rhizomal buds of A. sinensis (Oliv.) Diels were
collected from a field in Kunming Institute of Botany,
China. Rhizomal buds were of sterilized with half a
spoonful of orthocide in 100 ml of sterilized water for
30 minuetes, washed with 10% and 5% Clorox, con-
taining 1-2 drops of Tween 20 for 10 and 5 min, re-
spectively, and finally rinsed 2-3 times with sterilized
water. The buds were removed aseptically from the
rhizomes and cultured onto Murashige and Skoog (MS)
basal medium. After one month, shoot tips induced
from the buds were subcultured onto MS containing
3 mg/l benzyl amino purine (BAP or B) and 0.1 or 1
mg/l naphthalene acetic acid (NAA), and MS58 (0.1
mg/l BAP, 5 mg/l giberellic acid (GA), 150 mg/l citric
acid and double the strength of iron for the induction
of multiple shoots for one month. The shootlets were
subcultured in rooting media, which were MS con-
taining 0.2 mg/l BAP and 2 mg/l 3-indole acetic acid
(IAA), 0.1 mg/l kinetin (KN) and 0.02 mg/l NAA and
filter paper moistened with 1 MS liquid medium. The
plantlets were those grown in a tissue culture room
(controlled temperature = 25˚C, with 16 hours of light)
compared with those grown in a nursery. The me-
dium for growing in the tissue culture room using
sterilized vermiculite in pots and the medium for grow-
ing in the nursery using sterilized soil : ash : fertilizer
in the ratio of 2:2:1 in black plastic packets.
