Determining The Tuba-tuba Resistance to Saline Water
Statement of the Problem
Previous
Main Problem
Is tuba-tuba a halophyte?
Sub Problems
1. Can tuba-tuba withstand 5ppm level of
water salinity?
Objectives of the Study
Previous
Main Objective of the Study
To know whether tuba-tuba is a halophyte or
not.
Revised (if necessary)
To determine the level of water salinity can
tuba-tuba withstand.
1. How will the increasing level of salinity
affect the leaves and color of the
specimen?
2. How will the increasing level of salinity
will affect the growth of the
specimen’s roots?
3. How will the level of water salinity
affect the rate of leaves falling?
Revised (if necessary)
To determine the resistance of tuba-tuba to
saline water.
Minor Objectives of the Study
1. To be able observe the changes
happening to the tuba-tuba plant while
we apply different levels of salinity.

Hypothesis of the Study (only those which requires statistical tools/proofs)
Hypothesis Statement
Theoretical Basis/Support
Since tuba-tuba is a plant that

Scope and Limitations of the Study
The research will be focusing on the determination of the ability of the Tubang Bakod to resist
particular levels of salinity. The research shall be conducted in local areas and the effect of the present
environment to the specimen shall not be included in our research. Faucet water shall be utilized in our
research and the chlorination of the water shall not be included in the proposed research. The research
shall be conducted regardless of what weather is present since we have limited time.
PROBLEM # 1
Sampling Method
Simple Random Sampling
Explanation (why you chose this sampling
method)
There are no differences on a population on the
same species of plant
6 half-gallon ice cream containers
6 tuba-tuba stems
5 chicken nets
salt
Beaker
Triple beam balance
faucet water

Experimental Set-up (May be presented using a table or a diagram. Please explain briefly why your
design is such.)
Experimental Procedure (May be in paragraph, bullet or flow chart.)


Gather 6 tuba-tuba stems approximately 45 cm. from the base, place them on a temporary
container until roots start to grow.
Fill each of the six half gallon icecream container with 2 L of faucet water.
In each of five containers, add a specific amount of salt depending on the level of salinity the
container is assigned to. One will not be added with salt for that is where the control will be
placed.
Place one tuba-tuba stem on each container.
Use chicken net to support the stem and prevent it from falling.
Record the observations daily for 2 weeks.
