摘要:

丹参根段繁殖可缩短育苗周期,而适当的根段长度可减少种根用量,降低种苗生产成本。为此,本试验设置不同丹参根段种植长度,分别为5.5、4.0、2.5 cm(记为T1、T2、T3),并用不同浓度的吲哚丁酸(IBA)+萘乙酸(NAA)等量混合溶液进行催芽,研究3种根段长度对丹参农艺性状、产量及药效成分含量的影响。结果表明,100 mg?L-1 IBA+NAA等量混合溶液为诱导丹参根段发芽的最佳诱导液,该条件下的发芽率可达94.44%。T1处理的主花薹长度、地上分枝数、主花薹下叶面积显著(p<0.05)高于T3处理,3个处理的主花薹层数、株高、羽状复叶数、主茎直径、根鲜重、根干重差异不显著。T2处理的根冠比显著大于T1和T3处理。3个处理的植株收获率、小区产量和667 m2产量无显著差异,T1处理达1 204.40 kg。所有处理的丹参酮和丹酚酸B含量都高于《中华人民共和国药典(2020年版)》所规定的含量要求。综上,根段长度对丹参产量的影响不显著,各处理丹参的药效成分含量符合《中华人民共和国药典(2020年版)》要求。因此,丹参根段种植时可缩短根段长度,可结合植物生长激素催芽后种植。

Abstract:

Root segment propagation of Salvia miltiorrhiza Bge. can shorten the seedling raising time,and an appropriate length of root segments can reduce the consumption of seed roots and cut the production cost of seedlings. For this purpose,different planting lengths of S. miltiorrhiza root segments were set in this experiment,namely 5.5 cm,4.0 cm and 2.5 cm(denoted as T1,T2 and T3, respectively),and an equal-volume mixed solution of IBA and NAA under different concentrations were used for germination acceleration,to investigate the effects of 3 root segment lengths on the agronomic traits,yield,and contents of pharmacologically active ingredients of Salvia miltiorrhiza. The results showed that a 100 mg·L-1 mixed solution of IBA and NAA in equal proportions was optimal for inducing germination of S. miltiorrhiza root segments,with a germination rate reaching 94.44%. The main inflorescence length,number of aboveground branches,and leaf area below the main inflorescence of T1 were significantly(p<0.05)higher than those of T3. However,no significant differences were observed among the three treatments in terms of the number of main inflorescence layers,plant height,number of pinnately compound leaves, main stem diameter, fresh root weight and dry root weight. The root-shoot ratio of T2 was significantly greater than that of T1 and T3. No significant differences were found among the 3 treatments in terms of plant harvest rate,yield per plot,and yield per 667 m2,and the yield of T1 reached 1 204.40 kg per 667 m2. The contents of tanshinones and salvianolic acid B in all treatments exceeded the requirements stipulated in Pharmacopoeia of the People's Republic of China 2020. These findings indicated that planting length of root segments has no significant effect on the root yield of S. miltiorrhiza,and the contents of active ingredients meet the requirements. Therefore,the length of root segments can be reduced when planting,combined with pre-germination induction using growth hormones.

Key words: Salvia miltiorrhiza Bge., root segment length, agronomic traits, yield, active ingredient
