本试验以34份有代表性的甜瓜种质为实验材料,分别测定了不同品种的甜瓜叶片在坐果期的反射光谱以及叶绿素的含量。用叶绿素仪测得的数据表明:不同种质的甜瓜在坐果期的叶绿素含量具有差异性,其中新蜜11号的叶绿素含量将近灰鼠子的1.4倍,以光谱分析仪所测得的数据图谱反映:在510 nm到660 nm的波段内出现了一个反射吸收峰。根据所有的数据进行分析显示:甜瓜坐果期叶片叶绿素含量与光谱植被指数mSR_(705)、mND_(705)和PSSRb之间都有着较强程度的线性相关性。表明可以通过相关的植被指数来初步估计甜瓜叶片的叶绿素含量。
In this experiment, 34 representative melon germplasms were used as experimental materials, and the reflectance spectra and chlorophyll contents of different varieties of melon leaves during fruit setting were measured. Chlorophyll meter measured data show that: the different varieties of melon in the fruit setting chlorophyll content is different, including Xinmi 11 chlorophyll content of nearly 1.4 times the squirrel, the spectrometer measured data Reflect: In the 510 nm to 660 nm band appeared a reflection absorption peak. Based on all the data, the chlorophyll contents of melon at the fruit-setting stage showed a strong linear correlation with the spectral vegetation index mSR 705, mND 705 and PSSRb. This indicates that the chlorophyll content of melon leaves can be estimated through correlation of vegetation index.
