摘要: <正>研究了切根和截顶对湿地松苗木质量的影响,结果表明:(1)不同的切根处理对湿地松苗高和地径的生长有显著抑制作用,几种处理中,以9月份切根对苗高的抑制最小,以3次切根的处理对地径生长的抑制作用最小,但切根处理对湿地松苗木的高径比影响较小;(2)几种切根处理中,只有1次切根处理下地上部分的干重大干对照,2次切根处理根系干重最小。全苗千重以1次处理时最大,其次为对照;(3)不同的截顶处理下,湿地松苗高和地径生长都比对照低,单次截顶的苗高均比2坎截顶的高,地径生长以9月中旬处理的较大;(4)几种截顶处理中。根干重和侧须根干重都比对照低,其中8月中旬截顶处理下苗木生长最慢,单次截顶处理的侧主根干重均大于对照,全苗干重都明显小于对照。

Abstract: The explants in 4 em length collected from spring shoots of 3-year-old selected tree of Cerasus carnpanulata were inoculated on MS culture medium with 6-BA and IBA for adventitious buds mutiplication. The results showed that explants were prevented effectively from being brown and dying when the medium of 1/4MS were used. Explants grew fast and no vitrification when the medium plused with 1.0 mg/L 6-BA and 0.01 mg/L IBA. The medium of MS with 1.0 mg/L 6-BA and 0.3 mg/L GA3 was the best for multiplication and multiplication rate could reach to 600% during one culture cycle. Plantlets were to be transferred on the 1/2MS medium with 1.0 mg/L NAA and 0.2 mg/L IBA for rooting, when the explants were reached in about 4 cm. The root system could be developed well during 25 days and to be come a new plant. The rooting rate could reach to 92.1% after 35 days. The survival rate was above 94% when the plantlets were to be moved to nursery. The medium in 340//00 pearlite and 67%peat soil was good for rooting. This micropropagation technology could be applied in mass propagation.
