dc.description.abstract Seeds of five Obligate LDPs (Pot Marigold cv. Resina, Annual Phlox cv. Astoria Magenta, Cornflower cv. Florence Blue, Oriental Poppy cv. Burning Heart and Flax cv. Scarlet Flax) were sown into module trays containing homogeneous leaf mould compost. After germination, saplings of each cultivar were shifted into four light intensity chambers (42, 45, 92 and 119µmol.m-2.s-1) for a duration of 8h (from 08:00 to 16:00h). The findings of this study showed that Obligate LDPs grown under high irradiance (92 and 119µmol.m-2.s-1) flowered earlier. However, there was a non-significant difference between 42/45µmol.m-2.s-1 and 92/119µmol.m-2.s-1 irradiance levels. Although Obligate LDPs under 119µmol.m-2.s-1 flowered few days earlier than those received 92µmol.m-2.s-1 irradiance but the quality of plants (plant height and leaf size/appearance) was inferior. It is therefore concluded that for better plant quality and early flowering Obligate LDPs should be grown under 92µmol.m-2.s-1 irradiance. en_US
