一、研究目的 测定花生的叶绿素含量时,究竟选取哪个叶位的叶片才有代表性,以往未见对此有专门的报导。为摸清花生不同叶位叶绿素含量的变化,特作如下试验,以便今后在取样过程中选择一个合适的叶位,提供依据。 First, the purpose of the study Determining the chlorophyll content of peanuts, which leaf position to choose the leaves were representative, in the past there is no special report on this. In order to find out the changes of chlorophyll content at different leaf positions of peanut, the following experiments were specially designed so as to provide a basis for selecting a suitable leaf position in the sampling process in the future.
