Abstract: The effects of different concentrations of various hormones on the root number and length of Limonium bicolor were studied and the survival ratio and growth of plantlets in different substrates were evaluated. The results showed that MS+NAA 1.0mg/L gave the best result in root number, MS+IBA 1.0mg/L was best for root length, and the plantlets transplanted in peat and perlite substrate (1:1) resulted in the best growth. The cost of rooting and transplanting of plantlets of Limonium bicolor was also discussed.

Key words: Limonium bicolor, tube plantlet, rooting, transplanting

摘要： 以二色补血草为材料,研究了不同浓度激素配比对试管苗生根量及根长的影响,以及生根苗在不同移栽基质中的成活率和生长状况。结果表明,试管苗在MS+NAA 1.0mg/L培养基中的平均根量最多,在MS+IBA 1.0mg/L培养基中平均根长最长;生根苗在泥炭+珍珠岩(1:1)的基质中生长最好。同时进行降低成本的试验。
