Term
Before planting our seed, the hard seed coat must be weakened in a process known as
Definition
scarification
Term
After the _______ is weakened, the seed is placed in moist soil in a cooler for several months to break its dormancy in a process known as cold stratification.
Definition
testa
Term
After the testa is weakened, the seed is placed in moist soil in a cooler for several months to break its ________ in a process known as cold stratification.
Definition
dormancy
Term
After the testa is weakened, the seed is placed in moist soil in a cooler for several months to break its dormancy in a process known as __________.
Definition
cold stratification
Term
The endosperm degrades in our __________ seed and the energy is stored in the cotyledons.
Definition
exalbuminous
Term
The seed undergoes ________ germination leaving the cotyledons below ground.
Definition
hypogeous
Term
As our single shoot begins to grow rapidly, __________ inhibits lateral bud break.
Definition
apical dominance
Term
After a couple years of growth, our plant still has spiny leaves unlike its parent indicating that it is still in its __________ phase.
Definition
juvenile
Term
As our plant matures further, it becomes __________ to flower.
Definition
competent
Term
Our plant must first undergo a period of chilling to initiate floral buds in a process known as ________.
Definition
vernalization
Term
Then, our plant will flower when there is greater than 10 hours of sunlight per day indicating that it is a __________ with its photoperiodism controlled by phytochrome.
Definition
long-day plant
Term
Then, our plant will flower when there is greater than 10 hours of sunlight per day indicating that it is a long-day plant with its photoperiodism controlled by _________.
Definition
phytochrome
Term
As our flower opens, we notice that we have a ___________ flower because the stigma is mature before the pollen has matured or dispersed.
Definition
protogynous
Term
Since we only had one flower this year and our plant was growing in a greenhouse isolated from other pollinizers, we thought that we would not produce any fruit. However we did produce a fruit! We removed our fruit once it had reached ___________ and could continue to develop and ripen after being detached from the plant.
Definition
physiological maturity
Term
We expected it to be a ____________ fruit that arose without pollination and lacking any seeds. But to our surprise, we cut open our fruit and there were seeds.
Definition
vegetative parthenocarpic
Term
This means our plant was actually ________ and produced seeds without fertilization. We collect the seeds and sow them knowing that they will be perfect clones of our mother plant, and the process begins all over again.
