CHE SIGNIFICA THIGMOTROPISM IN INGLESE
tigmotropismo
Thigmotropism è un movimento in cui una pianta si muove o cresce in risposta ai tocchi o agli stimoli di contatto. Il prefisso tigmo- viene dal greco per "tocco". Di solito il thigmotropism avviene quando le piante crescono intorno ad una superficie, come un muro, un pentolino o un traliccio. Le piante arrampicate, come le viti, sviluppano viticci che avvolgono oggetti di sostegno. Le cellule toccate producono auxina e lo trasportano in cellule intatte. Alcune celle non toccate si allungheranno più velocemente in modo che la crescita cellulare si curva attorno all'oggetto. Alcune piantine presentano anche una risposta tripla, causata da impulsi di etilene che provocano lo spessore e la curva del fusto per iniziare a crescere orizzontalmente. Le radici si affidano anche al tocco per navigare nel loro terreno. Generalmente, le radici hanno una risposta negativa di tocco, cioè quando si sentono un oggetto, si allontanano dall'oggetto. Ciò consente alle radici di attraversare il suolo con una resistenza minima. A causa di questo comportamento, si dice che le radici siano negativamente thigmotropic. Thigmotropism sembra essere in grado di ignorare la forte risposta gravitropica di primarie radici primarie.
definizione di thigmotropism nel dizionario inglese
La definizione di thigmotropism nel dizionario è la crescita direzionale di una pianta, in risposta allo stimolo del contatto diretto chiamato anche: aptotropismo, stereotropismo.

Plant Tropisms: And Other Growth Movements
Darwin found that in a vertical bean root, a contact stimulus could divert the root
away from the vertical, i.e. thigmotropism overrides gravitropism; but in a
horizontal root downward curvature always occurred, even against a contact
stimulus, i.e. ...
Touchy climbers SCIENTISTS have already shown that plants have a sense of
touch, called thigmotropism. So which is more important for a climbing plant,
phototropism or thigmotropism? Recent research by Moshe Negbi of the
Department ...

Blue Ribbon Science Fair Projects
But another type of tropism occurs in plants — mostly vines — that must rely on
an outside support to gain height and strength. Called thigmotropism, it's the
response of a tendril when it touches a surface. Botanists have much to learn
about ...
Plants also have a touch response, called thigmotropism. If you have ever seen a
morning glory or the tendrils of a bean plant twist around a pole, then you know
that plants must be able to detect the pole. Thigmotropism works much like the ...

Functional Biology of Plants
Many plants respond to touch, and we will consider here thigmotropism in
tendrils. In thigmotropism, the direction of movement is determined by the surface
stimulated. Again, Charles Darwin was a pioneer in this area of research.

2 Describe phototropism, gravitropism, and thigmotropism. Tropisms are
directional growth responses and are permanent. Phototropism is the directional
growth of a plant caused by light. Gravitropism is plant growth in response to the

Plant movement in response to light is called (a) phototropism (b) geotropism (c)
thigmotropism (d) hydrotropism 2. Plant movement in response to gravity is called
(a) phototropism (b) geotropism (c) thigmotropism (d) hydrotropism 3.
Thigmotropism: Directional Response of Plant to Touch an Object There are
some plants like bitter gourd (Karela), bottle gourd (Lauki), grape vine and pea
plant which have weak stems and hence, cannot stand upright (or erect) on their
own.

Cyber Science 5' 2007 Ed.
Thigmotropism is a growth response to touch. A typical example of a plant that
exhibits thigmotropism is the mimosa pudica, commonly called makahiya.
Likewise, when a vine winds around a tree, fence or trelises, it shows response to
touch.
