What is Juvenility in plants?

Juvenility describes the phase of growth following germination from seed during which flowering does not occur and the bud meristem is not “competent” to respond to seasonal environmental inductive cues, and hence remains vegetative. This could take days or years depending on the species.

What is Juvenility and flower bud differentiation?

Definition: In most fruit trees of the temperate zone, flower buds are fully differentiated before winter, but in olives, differentiation occurs during or at the end of winter. A period of chilling temperatures is needed to proceed irreversibly from flower bud induction to differentiation.

What is a vegetative phase in plants?

In the vegetative phase, which begins at germination and continues through tillering, the tissues of growth (meristems) are busy producing leaves. This is important because sufficient leaf surface area is needed to capture sunlight and continue photosynthesis.

Why does vegetative phase precede flowering in a plant?

Answer: Dear it is the growth phase which has to take place before flowering… otherwise the reproductive organs will not develop properly. Flowers need energy, so usually there is a vegetative phase before flowering.

What Juvenility means?

Definition of juvenility 1 : the quality or state of being juvenile : youthfulness. 2a : immaturity of thought or conduct. b : an instance of being juvenile.

What is meant by Juvenility and maturity?

Juvenility is referred to the period during which a plant cannot be induced to flowers whereas maturity is occurred if a plant gives flowers. The changes from juvenile to mature characteristics are well known as phase changes phenomenon.

What is human juvenility?

Juvenility can be defined as a pre‐reproductive stage in which the youngster is relatively independent from parents for survival, but still sexually immature. In humans, children become relatively able to feed themselves and protect themselves from predators at about 6–7 years of age.

What is vegetation period?

The vegetation period is usually defined as the part of the year when the average daytime temperature is above a particular threshold. This threshold depends on the type of plant, but is usually between +3°C and +5°C.

What is the first vegetative stage of growth called?

germination stage
The germination stage is where the plant grows from the seed. In the right environment (which we’ll discuss below), seeds start to produce the familiar parts including roots, stems, and leaves.

What is vegetative change?

Vegetative phase change is the juvenile-to-adult transition in plants. This transition is distinct from the reproductive transition and is most prolonged and pronounced in woody species. Manipulating phase change may be an important avenue for plant improvement.

Which of the following factors influence the process of flowering?

So, the correct answer is ‘Photoperiod’

When can you plea Juvenility?

Claim Of Juvenility Can Be Raised Before Any Court, At Any Stage, Even After Final Disposal Of The Case: Supreme Court Reiterates. The Supreme Court has observed that the claim of juvenility can be raised before any Court, at any stage, even after final disposal of the case.

What is juvenility in plants?

Juvenility describes the phase of growth following germination from seed during which flowering does not occur and the bud meristem is not “competent” to respond to seasonal environmental inductive cues, and hence remains vegetative. This could take days or years depending on the species.

How does length of juvenile period affect plant breeding efficiency?

Length of juvenile period in most of woody plants is still considered as a big problem. Indeed, it affects the plant breeding efficiency, plant propagation, and to the selection of new cultivars.

Is there a difference in trichome density between young and old grafted plants?

In contrast, young grafted plants did not display a difference in trichome density compared to the donor tree. As previously reported by others, this phenotype can be associated to the juvenile phase and a young grafted plant is thus developmentally closer to the adult tree than to the juvenile seedling.
