摘要
一、前言叶绿素含量的常规测定,是用丙酮提取离析植物组织,然后通过分光光度计进行比色测定。对于大批量样品的上述操作则很费工费时。最近我们发表了利用液闪测量中的颜色猝灭,将放射性示踪剂(^(14)C-正十六烷参考液)加到叶绿素提取液中来进行植物叶绿素的测量。
MeasUring the chlorophyll concentration in wheat leaves with H number is a new rapid and accurate method and operation with radioactive tracer is avoided. The results from this method were significantly related with those from routine colorimetric analysis (r=0.899) and no significant differences between these two methods were found (p>0.05 for test).
