trait details of "Storage organs"

group of trait Morphology
description The occurrence of storage organs is usually associated with the ability of vegetative propagation and dispersal. Special storage organs may not only store nutritions but also water.

label name description
a Runner Lateral shoot (exceptional main shoot) with long thin internodes and adventitious roots. Severance from the mother plant causes the formation of individual ramets
ak Runner with tuberous tip Tuberous swelling of several internodes at the distal end of a subterranean runner, which mostly develops at the end of the vegetation period for storing food. Above ground shoots develop from the tuber the following season
ar Runner-like rhizome Subterranean or close to the surface situated shoot with cataphyllary leaves, which is more or less thickened, adventitiously rooted and long-lived (> 1 year). Difficult to distinguish whether the storage or the spread function is of prime importance
az Runner with bulbous tip Bulb at the distal end of a subterranean runner used for vegetative propagation, spread and storage, and sprouting the following season
b Bulbil Compressed above ground, vegetative lateral shoot with disproportionately developed or still absent organs, which develops into a new independently viable plant after severance from the mother plant, acting as propagation
f questionable  
h Tuft Ring-like arranged more or less orthotropously growing shoots, which are tightly-packed because of numerous, spatially more or less regular ramification of the basally crowded, adventitiously rooted parts of the shoots
hk Hypocotyl bulb Thickend hypocotyl with storage function
p Pleiocorm System of compact, perennial shoots occuring at the proximal end of the persistent primary root. The innovation buds are situated in the axils of basal leaves. The connections between the shoots and the primary root are persistent
r Primary storage root Thickened primary root including the thickened hypocotyl and epicotyl, acting as a storage function
rh Rhizome Subterranean or close to the soil surface, mostly thickened shoot with short internodes, adventitious roots and (mostly) cataphyllary leaves. It stores and is long-lived (> 1 year). Ramification followed by distal decaying causes the formation of ramets
rp Rhizome-like pleiocorm System of more or less crowded shoots, persisting several years which arise mainly at the proximal end of the primary root especially in the first years of the individual cycle. At first the innovation shoots arise from basal leaf axils, later from the rhizome like, adventitiously rooted shoots, which later lose their connection with the primary root
sk Shoot tuber Thickened, mostly subterranean, roundish, short lived (< 1 year) part of a shoot which is used as storage
su Succulence Presence of special water storing tissue
sw Secondary storage root Partly thickened adventitious or lateral root acting as storage. Contrary to root tubers it has not lost primary root functions, such as absorption and anchoring
t Turio Vegetative compressed, mostly bud like shoot, which hibernates with leaves or parts of leaves and sprouts only after severance from the mother plant
wk Root tuber Thickened, not ramified adventitious root, formed by an innovation bud, which primarily acts as storage but rarely as absorption
z Bulb Compressed part of a shoot, partly with fleshy cataphyllary leaves or leaf bases, acting as storage
