REPRODUCTION
Most traits are adapted from Klotz et al. (2002).
Type of reproduction:
-
s: by seed or spore
-
ssv: mostly by seed, rarely vegetatively
-
sv: by seed and vegetatively
-
vvs: mostly vegetatively, rarely by seed
-
v: vegetatively
Propagule:
-

-
Bulb
-
Fruit
-
Fruit fragment
-
Fruit with appendage
-
Plant fragment
-
Rhizome
-
Root
-
Seed
-
Shoot
-
Spore
Dispersal mode (vectors):
-
Anemochory (wind dispersal)
-
Autochory (self dispersal)
-
Endozoochory (dispersal via an animal’s digestive system)
-
Epizoochory (external dispersal by animals)
-
Hydrochory (water dispersal)
-
Myrmecochory (ant dispersal)
-
Unspecialized
Breeding system:
-
Allogamous: obligate outcrossing; gametes originate from different sporophytes
- Facultative allogamous: mainly outcrossing, selfing is possible
- Autogamous: obligate selfing; gametes originate from the same sporophyte
- Facultative autogamous: mainly selfing, outcrossing is rare
- Mixed mating: both outcrossing and selfing are common
Sex type:
-
Androdioecious: male and bisexual (or monoecious) flowers on different plants
-
Andromonoecious: male and bisexual flowers on same plant
-
Dioecious: male and female flowers on different plants
-
Gynodioecious: female and bisexual (or monoecious) flowers on different plants
-
Gynomonoecious: female and bisexual flowers on same plant
-
Hermaphrodite: all flowers bisexual
-
Monoecious: male and female flowers on same plant
-
Trimonoecious: bisexual, male and female flowers on same plant
-
Trioecious: male and female and bisexual, and/or monoecious, gynomonoecious or andromonoecious flowers on different plants
Fruit type:
-
Aggregate drupelets: made up of many drupes but formed from a single flower, each drupe containing one seed
-
Berry: indehiscent, with fleshy pericarp and woody testa
-
Capsule: dehiscent, fruit with multiple carpels; may open in various ways splitting down two sides
-
Drupe: indehiscent, with fleshy epicarp and mesocarp and woody endocarp; testa not woody
-
Follicle: dehiscent; a single carpel splitting down one side
-
Head of achenes: made up of many achenes but formed from a single flower
-
Loment: special kind of dry dehiscent fruits which break up into sections containing a single seed, instead of splitting open
-
Missing: fruits are not developed (i.e. ferns, gymnosperms)
-
Nut: indehiscent, with dry pericarp
-
Nutlet: indehiscent, dry single-seeded fruit
-
Pod: dehiscent, single carpel splitting down two sides
-
Pome: indehiscent, fleshy; fruit (apple like) with a thin skin, not formed from the ovary but from another part of the plant (receptacle)
-
Schizocarp: dry fruit that splits up into separate fruitlets due to true septae across the carpel margins
-
Siliqua: dehiscent with two carpels splitting away from a central column
-
Vegetative
Fruit size:
Fruit length in mm.
Pollination mode:
-
Cleistogamy: selfing in unopened, rudimentary flower
-
Geitonogamy: selfing by a neighbouring flower
-
Insects: pollination by insects
-
Pseudocleistogamy: selfing in unopened flower
-
Selfing: spontaneous pollination within a flower
-
Slugs: pollination by slugs
-
Water: pollination on or below water
-
Wind: pollination by wind
Seed length:
Seed length in mm.
Seed width:
Seed width in mm.
Seed mass:
Seed mass in mg.
Seed production:
Number of seeds produced per plant.
Seed bank type:
According to Thompson et al. (1997)
-
I:transient seed bank with seeds that persist in the soil for less than one year
-
II: short-term persistent seed bank with seeds that persist in the soil for at least 1 year but less than 5 years
-
III: persistent seed bank with seeds that persist in the soil for at least 5 years
-
IV: seeds present but cannot be assigned to one of the three seed bank types
Flowering time:
First and last month of flowering period.
