The observation on the microstructure of six orchids demonstrated that they have the typical orchidaceous roots with velamen and thick cortical tissue.
Based on the theoretical analysis, the electrohydrodynamics (EHD) enhancement of condensation heat transfer inside vertical tube for five representative electrodes were investigated.
Exodermis An outermost layer of thickened or suberized cortical cells that sometimes replaces the epidermal layer in the older parts of roots if the epidermal cells have died.
Based on the catalytic effect of thiocyanate on the oxidation of alizarine red by potassium bromate,a new catalytic spectrophotometric method for the determination of trace thiocyanate was developed.
