Abstract
Scions from the one- and two-years old and the nodes of Ligusticum chuanxiong stem were used to study the rooting ability with the treatment of plant growth regulators planted to different bed soils as the alternative propagation for the present method by rhizome. The rooting ratio in the scion from the one- and the two-years old plants showed any difference, but that was ranged from 94% to 100% in the first node and from 56% to 64% in the second node from the bottom of the stem. The scion of first node from both the plants showed more than 90% in the root ratio and 16 in the number of rooting and growed more than 31cm in the root length. The Rootone-F and 250ppm of NAA were most effective for the promotion of rooting. Rooting ratios in the sand and in the mixture of vermiculite and perlite as bed soils were about 18%, but that in the cultured soil considerably decreased.
토천궁(土川芎)의 종묘비(種苗費) 절감(節減)과 증식율(增殖率)을 향상시키기 위하여 소목번식(掃木繁殖)에 대한 시험을 수행(遂行)한 결과를 요약(要約)하면 다음과 같다. 1, 삽수(揷穗)의 종류에 따른 발근률(發根率)은 1년생과 2년생에서 채취한 삽수간(揷穗間)에는 큰 차이가 없였고, 삽수(揷穗)의 부위(部位)에 따라 차이가 심하였으며, 첫째마디 부위(部位)를 삽목(揷木)할 패는
