Seeds of Nepenthes mirabilis were germinated in vitro on
composted medium. All seeds were germinated under white
(fluorescent), red, green, blue and yellow light. Over a period of
27 days, some Nepenthes seeds under white and red light
germinated first, and those under green light were the last ones to
germinate. The highest average speed of emergence was recorded
for seedlings under red light. All healthy and complete seedlings
were counted after 60 days. Seedlings under yellow light were the
most vigorous with the highest germination index and average
height of 0.79 cm. Seedlings under yellow light and white light
exhibited the highest average number of roots and light green
leaves as well as greatest root length, but seedlings under green
light had few roots and pale green leaves. There were more young
leaves on seedlings under yellow light (average 5.2) and red light
(average 5.0) compared with those under green light and blue
light.
