摘要

在玉米初生根(cv;气相色谱-质谱联用(GC-MS)技术测定的内源性吲哚-3yl-乙酸(IAA)主要分布在石碑中。在白光下水平放置2 h后，伸长区皮层下部的IAA水平有轻微但显著的提高。

Endogenous indol-3yl-acetic acid in stele and cortex of gravistimulated maize roots

In primary maize roots (cv. LG 11) endogenous indol-3yl-acetic acid (IAA), measured by gas chromatography-mass spectrometry (GC-MS) technique, was predominantly located in the stele. When these roots were placed for 2 h in horizontal position and in white light, the IAA level was slightly but significantly enhanced in the lower part of the cortex of the elongation zone.
