以草石蚕为试材,研究了不同浓度萘乙酸(NAA)处理对草石蚕扦插效果的影响。试验结果表明,在试验浓度范围内,各NAA浓度处理可促进草石蚕扦插苗的生根及生长,且随着NAA浓度的增加,其根长、根数、根鲜质量、根干质量、株高和根系活力均呈先上升后下降的趋势,其中以浓度为700 mg/L的NAA处理效果最好。
Using the stone worm silkworm as test material, the effects of different concentrations of NAA on the cuttage of Ardisia mandshurica were studied. The results showed that within the experimental concentration range, NAA concentration could promote rooting and growth of M. cutanea seedling. With the increase of NAA concentration, root length, root number, root fresh weight, root dry weight, The root activity and root vigor both showed a trend of first increasing and then decreasing, of which NAA with a concentration of 700 mg / L had the best effect.
