Report

 The subject used in this research study is the Mongo
(Vigna radiata) exposed to different colors of water
cellophane covered in the cold frame as alternate
source of light.
 The growth of mongo seeds in terms of onset of true
leaf and number of sprouts and growth of mongo
sprouts in terms of number of leaves, sprout height
and biomass exposed to different colors of light were
monitored for two weeks and compared.
1. On the first part of the experiment, what is the growth of the
mongo plants exposed to different colors of light and sunlight
in terms of:
 Onset of true leaf
 Number of sprouts
2. On the second part of the experiment, what is the growth of the
mongo plants exposed to different colors of light and sunlight
in terms of:
 Onset of true leaf
 Number of leaves
 Sprout height
 Biomass
3. Is there a difference between the growth of the
controlled plant and the experimental plant in terms
on onset of true leaf, number of leaves, sprout height
and biomass?
4. Which color of light would be the best for the plant’s
growth and has the big effect for the plants?
 This study is only limited to the determination of the
effect of the different colors of light such as red, yellow,
green, blue and white on the growth of the mongo
plant (Vignaradiata) in terms of a) onset of true leaf,
b) number of leaves, e) sprout height and f) biomass.
The differences must be recorded in each set-up of
plant. There would be thirty seeds assigned to a single
color. The subjects should be observed in two weeks.
 Seeds
Prepare the cloth
and sacks and
assign colors.
Observe and
record data.
Pick 10 seeds for
each treatment.
Lay seeds on top
of each cloth;
expose seeds to
light.
Water the seeds,
observe until
seeds grow into
sprouts.
 Sprouts
Pick 10 seeds for
each treatment.
Put soil in the cold
frame and plant
the seeds.
Assign colors and
put water
cellophanes into
each frame.
Observe and
record data.
Monitor growth,
water the plants
with 500mL of
water everyday
Sunlight will
change in color
when passing in
the frames glass.

Post-hoc Analysis of Biomass
.9509
 Sunlight has the best effect on plant’s growth than the
other group of plants exposed to different colors.
 White and yellow helps the sprouts grow faster than
sunlight.
 The sprout height of the plants exposed to sunlight
and white is shorter than the plants exposed to the
different colors of light.
 The biomass of the plants exposed to white and
sunlight is greater than the other groups.
 Find a much bigger place to conduct the experiment
 Extend the duration of the experiment to attain more
significant results.
 Try using secondary colors to have more efficient
results.
 Use artificial lighting instead of water cellophane to
see a greater and more specific effect to plants.
