摘要
分别使用不同浓度(600 mg/L、800 mg/L、1 000 mg/L、1 200 mg/L、1 400 mg/L)的3种生长调节剂萘乙酸、吲哚乙酸、吲哚丁酸对茶梅嫩枝穗条处理后进行单因素扦插试验,经过150天的生长后,调查其生根率、平均生根数、平均根长等生长指标,并进行方差分析和多重比较,探究最适合茶梅扦插繁殖的方法。结果表明,同种条件下,3种生长调节剂不同浓度对茶梅嫩枝穗条的生根具有显著的影响,萘乙酸及吲哚乙酸效果较好,吲哚丁酸效果相对较差。其中以1 200 mg/L吲哚丁酸处理穗条后的扦插效果最好,其生根率为66.7%,平均根长为0.83 cm,平均生根数为5.8条;1 000 mg/L的萘乙酸处理穗条的效果次之,生根率为53.4%,平均根长为1.34 cm,平均生根数为7.1条,均显著好于对照。
In order to study the cutting technology of Camellia sasanqua in this test, the cuttings were dealt with three kinds of rooting agent （NAA, IBA, IAA） in different concentrations （600 rag/L, 800 rag/L, 1 000 rag/L, 1 200 mg/L, 1 400 mg/L） for cutting experiment by using the method of single factor test. After 150 days＇ growth, by analysis of variance and multiple comparisons, the most suitable cutting propagation methods for Camel- lia sasanqua were found. The results showed that： under the same condition, the different concentration levels of different kinds of rooting agent had significant effects on the growth of Camellia sasanqua cutting. Generally speak- ing, Cuttings soaked with 1 200 mg/L IBA for 30 seconds took root best, the rooting rate was 66.7 %, with an average root length of 0. 83cm and the average root number of 5.8 ; Cuttings soaked with 1 000 mg/L NAA for 30 seconds took root better than the others, itg rooting rate was 53.4 %, with an average root length of 1.34 cm and the average root number of 7. 1, and all treatments were much better than CK.
