摘要
以芥蓝种子为试材,研究不同浓度萘乙酸（NAA）营养液对芥蓝幼苗根、茎、芽生长的影响。结果表明：不同浓度的萘乙酸培养液对芥蓝的生长有不同的影响,即有不同程度的促进或抑制作用。其中0.001 mg/L NAA对侧根的生长表现出促进作用,同时对子叶生长也表现出促进作用,并且对根重和根长有促进作用;0.0001 mg/L对根重和根长有促进作用,但对侧根的生长（根数）没有促进作用;0.1-10 mg/L浓度范围内的NAA对芥蓝幼苗的生长有抑制作用,但10mg/L对茎的加粗却表现出明显的促进作用。
This article analyzed the effect of different concentration of naphthalene acetic acid（NAA） on the growth of the root and bud in Chinese Kale（Brassica alboglabra L. H. Bailey）. The results showed that, the effect that was promoting or restraining differed from different concentration of NAA on the growth of the root and bud of Chinese Kale. The 0. 001 mg/L NAA could accelerate the growth and development of lateral root and cotyledon in Chinese kale, meanwhile, also promote the growth of the weight and length of root. The 0. 0001 mg/L NAA also could promote the growth of the weight and length of root, but there was no promoting function on the lateral root （number of root）. The NAA in the range of 0. 1～10 mg/L performed restraining function to young Chinese kale, but the 10 mg/L increased caulis width obviously.
