Each pot contained a single transplanted leaf entity; 30 entities were tested for survival in each medium. The rooted and survival rate (%) was calculated after four weeks as follows: (number of survivals/number of transplanted leaf entities) x 100% . The experiment was carried out in a shaded greenhouse. Light intensity inside the greenhouse was 1.17% that of natural sunlight. The measured photo flux density in the greenhouse on a typical sunny day was 19.75 มิวmol mยกกำลัง -2 sยกกำลัง-1. The greenhouse temperature was controlled to be between 20 and 30 C for this experiment.
