Abstract

Seeds tend to undergo dormancy after being released from the parents. Seed dormancy
is a condition that prevents germination in a specific period of time. When the environmental
conditions are favorable, germination starts and the seed’s embryo continues its growth (Swain
et al., 1995). Germination begins when the seed absorbs water in a process called imbibition,
then special enzymes that are responsible for seed growth are activated by water. This process
is completed when the radicle (a part of the embryo that develops into the primary root) has
grown out of the seed coat. Seed germination is controlled by many factors such as plant
hormones, temperature, light, pH, etc. In this experiment, we tested the effect of sugar
(sucrose) on the germination rate of chia seeds. We did so by having each group member place
five chia seeds in four different containers (for a total of twenty seeds per student) containing a
sucrose solution of 0%, 2%, 4%, or 6%. The chia seeds were then observed for fifteen days and
data on sprouting and germination was collected every five days. After everyone had collected
their data, we ran a one-way ANOVA test and a Tukey’s test to determine whether our results
were significant. Our results found that the growth rate means were significantly different.
Specifically between the control and 4% sucrose solutions, and control and 6% sucrose solution.
In addition, the germination rate showed a decreasing trend by increase in the concentration of
sugar.
