Germination and Productivity




Introduction
In this lab the study was about the germination of seeds both in the light and in the dark. In fact, the assumption of the experiment ask question and make the hypothesis as science to know the truth of germination. Eventually, different method come up to determine the fact of this experiment, bring some result of  both germinations light and dark.

  •    Question: Can plants germinate in the dark?
  •   Hypothesis: Seed don't germinate in the dark
  •   Treatments: Light and dark
  •     Experiment control: Germination seedling in the dark

Method

  1.            Get a 6*6 tra
  2.       Put soil organic in each of hole
  3.       Water in the soil to make it moisture
  4.         Four seeds in each of the them
  5.         Check after one week to see what happened

Result

Dark and light treatment

Percent germination of dark
57/144 * 100= 39.6%

percent germination of light
69/144 * 100% = 48%





 Light
Before:   Wet plants: 18.9 g.
After:      Dried plants: 10 g.
Duration: 8mn
Loss: 8.9g.
Temperature 400F

Dark
weight before dry 11.4g
weight after dry 2.0g


GPP and NPP
Calculate the GPP  of the dark treatment:

GPP= NPP + R
Then: NPP= 10g and R= 18.9g
GPP= 10g+18.9g             GPP= 28.9g


Calculate the GPP of the light treatment

GPP= NPP + R
Then: NPP= 2..g and R=11.4g
GPP= 2.0g + 11.4g         GPP= 13.4g

Comparison

The difference in appearance between the dark and light treatment plants are:  
  • The dark treatment had a color yellow. No photosynthesis because that treatment was in  a dark area.
  • The light treatment had a color green because that treatment was in presence of sunlight, that's why the light treatment plant reflects green by photosynthesis 

There was growth in the dark treatment plants.
The seed can germinate in the dark without receiving sunlight. It does not mean the can growth for long period. However, the seed grow in the dark are weak, and thy will never green.
