摘要
以从新鲜玉兰叶片中提取出的新鲜叶绿素为原料,用WGS-9型色度仪分别测出叶绿素提取液在不同波长的光和不同照射时间以及不同温度下的吸收光谱,通过对吸收光谱的分析得出不同光照和温度对叶绿素的影响及对叶绿素中成分的破坏情况。文中对实验结果一一作了解释,并进一步试着推出绿色植物或蔬菜在运输和保存过程中比较适宜的照明光的波长范围和温度。
Using fresh chlorophyll distilled from fresh leaves of yulan as experimental material, this research analyses the change of the absorption spectra of chlorophyl under light of different wave length, different illuminating time, different temperature by means of using the WGS-9 chroma analysing instrument. The research data indicates the degree of destruction to chlorophyll under light of different wave length, different illuminating time, different temperature. At last, the results of this experiment are explained and applied to further application of daily life.
