Shoot types (on woody plants)

Long shoot (長枝): elongated, long node
Short shoot, spur shoot or fruit spur (短枝)
spur shoot
on Japanese larch (Larix kaempferi)
(Ref. Seasonal heterophylly)
Shoot
A: shoot with long internodes and well developed nodes. B: long shoot and dwarf shoots of Larix. C: ramification of shoot: dichotomic, overtopping, monopodial, sympodial (from left to right).

Embryo and seedling (胚と芽生)


Typical empbyo that contains hypochotyl: Diospyros kaki

cotyledon

Stem ()


Node (節): holding buds
Internode (節間): between nodes

stem

Aerial stem or aboveground stem (地上茎)
Subtarranean stem or underground stem (地下茎, s.l.)
Rhizome (地下茎, s.s.) ≈ rootstock (根茎)

Primary rhizome: primarily developing for underground stems
Secondary rhizome: originating from aboveground stems

Tuber, s.s. (stem tuber, 塊茎), from stems

⇔ Root tuber (storage root, 塊根), originating from roots, not from stems
Tuber, s.l. = stem tuber, s.s. + root tuber

Bulb (true bulb, 鱗茎)

Climbing plant (つる植物)

Vine
herbaceous, relatively thin-stemmed climber (s.s.)
Liana (liane)
woody climber
twiner: twining by the stems Ex. Pueraria lobata
climber

tendril climber: tendril or hook Ex. Galium spurium
root climber: aerial root Ex. Schizophragma hydrangeoides

leaner: only leaning against the object Ex. Rosa multiflora

Branch ()

Branch of woody plants
shoot apical bud = terminal bud
bud scale
axillary bud
leaf scar
bud scar
node
internode


Bud ()


A small lateral or terminal protuberance on the stem of a plant that may develop into a flower, leaf, or shoot

Winter bud (冬芽)


A dormant plant bud enclosed in a protective covering which enables it to survive during the winter ⊂ dormant bud
