Abstract
The concentrations of indole-3-acetic acid (IAA), naphthaleneacetic acid (NAA) and 2,4-dichlorophenoxyacetic acid (2,4-D) were followed for 35 days in cell-free liquid medium containing 100, 50, or 0% Murashige-Skoog (MS) salt base. Although the concentrations of NAA or 2,4-D remained constant the level of IAA decreased to only 11% of the original concentration after 35 days in the presence of 100% MS salt base. The observed rate of IAA degradation was accelerated by the presence of MS salts.
摘要
在含有 100%、50%或 0%Murashige-Skoog（MS）盐基础的无细胞液体培养基中，跟踪了吲哚-3-乙酸（IAA）、萘乙酸（NAA）和 2,4-二氯苯氧乙酸（2,4-D）的浓度 35 天。尽管 NAA 或 2,4-D 的浓度保持不变，但在存在 100%MS 盐基础的情况下，IAA 的水平在 35 天后降至原始浓度的 11%。MS 盐的存在加速了 IAA 的降解速度。
