We evaluated the effects of sucrose and carrot juice (CJ) in different media on growth and net CO2 exchange rate of Phalaenopsis hybrid ‘Pink’.
The combination of 30 g L−1 sucrose and 10% CJ in MS medium resulted in the highest leaf length, SPAD leaf greenness, total chlorophyll and CO2 uptake.
The combination of 40 g L−1 sucrose and 10% CJ in VW medium resulted in the highest leaf length, SPAD leaf greenness, total chlorophyll and CO2 uptake.
