The Effects of the Different Substrates on Banana Plantlet Growth and Photosynthetic Characteristics
The paper was aimed to screen suitable culture medium from six culture media of different ratio between coconut coir and lateritic soil for banana plantlet .Brazil Banana plantlet was selected and lateritic soil was used as the reference. The Li-6400 photosynthesis instrument was used to measure the diurnal variation of photosynthetic rate and transpiration rate.The result showed that the change of photosynthetic rate, transpiration rate and stomatal conductance was similar under different culture medium. When the ratio between coconut coir and lateritic soil was 1:2, the growth of banana plantlet was the best, and the above measured values were the highest; when the ratio was 4:1, the result was the worst. The intracellular concentration of CO2 was in the opposite.The growth of banana plantlet was the best when the ratio between coconut coir and lateritic soil was 1 : 2.
