The Use of the SPAD-502 Chlorophyll Meter during the Flue-cured Tobacco Growth
Tianfu Li · Guizhou nongye kexue · 2006
The field experiment was tested to investigate the relationship between chlorophyll content in leaves of flue-cured tobacco and the value measured by SPAD-502 chlorophyll meter to discuss the application prospect of SPAD-502 chlorophyll meter in tobacco production.The results show that the optimal position measured by chlorophyll meter is the basic of the leaf,and there is a significant correlation between the values of different leaf position and degree of maturity measured by SPAD-502 chlorophyll meter and their chlorophyll contents measured in the laboratory,and the linear equation is y=ax+b.
