1 Angela Shemae SF. Gonzales Rendel John D. Rulona Effect of Different Colors of Light to Mongo Plant’s ( Vigna Radiata) GrowthAngela Shemae SF. GonzalesRendel John D. Rulona
2 What was the study all about? 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.
3 What were the problems?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 leafNumber of sprouts2. 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:Number of leavesSprout heightBiomass
4 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?
5 What was the scope of the study? 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.
6 What were the procedures done? SeedsPrepare the cloth and sacks and assign colors.Pick 10 seeds for each treatment.Lay seeds on top of each cloth; expose seeds to light.Observe and record data.Water the seeds, observe until seeds grow into sprouts.
7 What were the procedures done? SproutsPick 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 everydaySunlight will change in color when passing in the frames glass.
8 What were the results?Graph of the number of sprouts
9 What were the results?Graph of number of leaves (Week 1)
10 What were the results?Graph on number of leaves (Week 2)

14 ConclusionsSunlight 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.
15 Recommendations 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.
