Hort 1001 Lecture 4

Front 1

True or False: Perennial plants are produced from seed in the spring and die at the end of the growing season.

Back 1

False. Annual plants are produced from seed and die at the end of the season.

Front 2

Vegetable phase

Back 2

Stem growth occurs by the apical meristem and through the addition/elongation of cells.

Front 3

True or False: The appearance of inflorescences serve as the signal to the transition of the plant changing from vegetative to reproductive.

Back 3

True

Front 4

Terminal Inflorescence

Back 4

When the apical meristem transforms into a reproductive meristem and produces an inflorescence.

Front 5

Determinant growth is popular in what?

Back 5

Agriculture and ornamental production

Front 6

True or False: Corn is an example of a plant with determinant growth.

Back 6

True

Front 7

Indeterminate growth

Back 7

Referred to as indeterminate since the length of the stem is not determined, but can continue throughout the year. Production continues until frost or another external factor.

Front 8

Why is indeterminate growth beneficial for landscaping?

Back 8

It allows for flowering plants all season long.

Front 9

True or False: It is normal to prefer indeterminate growth for gardening.

Back 9

True

Front 10

Solitary Flower Inflorescence

Back 10

Simple flowers that only support one flower.

Front 11

Peduncle

Back 11

The stem attaching the flower to the node from which it grew on a solitary inflorescence plant.

Front 12

Bract

Back 12

2nd to last node supports a leaf and the terminal node supports an inflorescence and a leaf

Front 13

Simple inflorescence (umbel)

Back 13

Contain peduncle, rachis, pedicel and a single flower structure.

Front 14

True or False: In a simple inflorescence, pedicels radiate out from a central point at the end of the peduncle and attach to a single flower.

Back 14

True

Front 15

Compound inflorescence (umbles in umbles)

Back 15

Similar to simple inflorescence except that they have a group of flowers instead of a simple flower.

Front 16

True or False: In a compound inflorescence, umbles radiate out from the end of the peduncle and the rachis is attached to the end of the umble .

Back 16

False: In a compound inflorescence, rachi radiate out from the end of the peduncle and the umbel is attached to the end of the rachis .
