Rockweed Phenophase Definitions
Directions:
Record observations on a subset of 10 individual rockweeds at your site by determining how many observed individuals are in each phenophase. Do not make observations on rockweed individuals next to each other but every other one or haphazardly along the 10-meter transect line.
As you report on phenophase status (Y, N or ?) on the datasheets, refer to the definitions on this sheet to find out what you should look for, for each phenophase of this species. To report the intensity of the phenophase, choose the best answer to the question below the phenophase definition.
Leaves
New side branches: One or more new sides branches with smooth tips are visible on the plant. Side branches are considered “new” until they develop a receptacle, or until they reach a similar width and tough texture as the mature shoot on which they are growing. Do not include side branches with ragged tips, where a receptacle has recently detached.
How many individuals out of the ten observed have new side branches present? 1,2,3, … 10
Flowers
Flat receptacles: Mostly flat, oval-shaped, olive-green receptacles are visible on the plant.
How many of the ten observed individuals are in this phase? 1,2,3, … 10
Smooth inflated receptacles: Mostly inflated, smooth, olive-green receptacles are visible on the plant.
How many of the ten observed individuals are in this phase? 1,2,3, … 10
Dotted inflated receptacles: Mostly yellow or orange receptacles studded with small, raised dots are visible on the plant. Do not include receptacles that are torn or ruptured.
How many of the ten observed individuals are in this phase? 1,2,3, … 10
Torn receptacles: Mostly torn or ruptured, orange or dark brown receptacles are visible on the plant or plant has mostly ragged tips where receptacles have recently detached.
How many of the ten observed individuals are in this phase? 1,2,3, … 10
