Abstract:
This research was to study the effect of shading net on chlorophyll and 2-acetyl-1-pyrroline (2AP) contents of pandan (Pandanus amaryllifolius Roxb.) leaves. The experiment was carried out based on randomized complete block design (RCBD) at four different levels of shading net (0, 50, 60 and 70%), with 3 replications and the leaves were harvested 6 months after planted. The results showed that there were significant differences in the chlorophyll and 2AP contents in leaves growing under different levels of shading net. The chlorophyll contents of pandan leaves cultivated under 50, 60 and 70% of shading net were higher than those exposed out of field. The chlorophyll contents were 0.56 ± 0.06, 0.89 ± 0.02, 0.77 ± 0.03 and 0.84 ± 0.12 mg/g fresh plant at shading net of 0, 50, 60 and 70%, respectively. The amount of 2AP of pandan leaves increased as shading net decreased. The 2AP content were 5.40 ± 0.01, 5.40 ± 0.02 and 5.60 ± 0.01 µg/ g fresh plant at shading net of 70, 60 and 50%, respectively. However, when planted without shading net the 2AP content was decreased to be 5.55 ± 0.01 µg/ g fresh plant.
