Influence of light on seed germination of Calamus manan
1990

Freshly collected seeds of Calamus manan were sown under three light conditions: (a) in the open (b) under moderate shade of "attap" roofing and (c) under intact forest canopy. At 2, 4 and 6 month intervals, the samples that had been sown under shade ((b) and (c)) were moved into the open. Germination under all treatments occurred day 28 from sowing and was completed by day 60. Under open and attap condition, the cumulative germination percentage achieved 50 percent by about 6 weeks. Under forest, the cumulative germination percentage did not reach 50 percent. The results indicate that although the seeds appear insensitive to light regimes for germination, some amount of light (attap conditions) optimizes germination of Calamus manan.
