摘要
以枣树(Ziziphus jujuba Mill)3个品种的试管苗叶片和大田苗叶片为材料,采用丙酮-乙醇提取法和SPAD-502(Minolta Co.Japan)便携式叶绿素计活体测定法测量其叶绿素的含量。结果表明,枣树3个品种大田苗的叶绿素含量均大于试管苗的叶绿素含量。
The chlorophyll contents in the leaves of three Ziziphus jujuba varieties were determined using acetone-ethanol extraction method and the SPAD-502 in vivo measuring meter.The result showed that the chlorophyll content of the three jujube varieties growing in the field was higher than that in vitro.
