Abstract
An experiment was carried out to study the effects of light intensity on the growth and flowering of Curcuma alismatifolia var. Pink. The experiment was conducted in Ladang 2 UPM. Four levels of shading consisting of T1 0 shade without using black net T2 30 shade T350 shade and T4 70 shade were used. The average light intensity measured for T1 T2 T3 and T4 was 1207.69 mol m-s- 497 mol m-s-. 398.61 mol m-s- and 286.88 mol m-s- respectively. There were 5 replications used for each treatment. The plant characteristics measured were plant height number of leaf leaf area photosynthesis rate inflorescence length inflorescence diameter number of flowers and sepals. Results obtained showed that there were differences in plant height number of leaf photosynthesis rate and number of flowers produced for plants grown under different light intensities. However there was no significant difference in inflorescence length produced. The study showed that T3 50 shade gave the best results for the growth and inflorescence production for Curcuma alismatifolia var. Pink with optimum plant height at 37.71cm highest number of leaves produced with an average of 5.95 leaves leaf diameter of 2.64cm and also produced the most number of inflorescences with good colour retention.
