This study was carried out to investigate the effect of mulching materials and GA₃ treatment in shade culture on the growth of Lilium spp. during high temperature season. The shade levels were 35%, 55% and 75% of full sunlight. In ´Casablanca´ , the thickest stem diameter was observed under the straw mulching at 55% shade. And under the 75% shade condition stem diameter increased with the more application of GA₃. Length of internode was longest in husk mulching at 75% shade. And GA₃ tended to increase length of internode with the more shade condition and more application. Plant height was highest in husk mulching and 3 time application of GA₃ at 75% shade. Chlorophyll contents increased with the more shade condition. In ´Antila´, the stem diameter increased at 35% shade and thickest stem diameter was observed at one application of GA₃. Length of internode and plant height was longest in husk mulching at 75% shade. In ´Nepal´, husk mulching at 35% shade had most effective on stem diameter. Longest internode was observed with the two times application of GA₃ at 75% shade. Plant height was highest in husk mulching at 75% shade.
