vernalization

Other annual plants require winter cold to complete their life cycle, this is known as vernalization.

Many biennials require a cold treatment, or vernalization, before they will flower.

This vernalization, as it is known, is a fascinating phenomenon.

Many perennial and most biennial plants require vernalization to flower.

Some plants flower early in their life cycle, others require a period of vernalization before flowering.

Some seeds require exposure to cold temperatures (vernalization) to break dormancy.

It is possible to devernalize a plant by exposure to high temperatures subsequent to vernalization.

Biologically, the chilling requirement is a way of ensuring that vernalization occurs.

Spring cereals are planted in early springtime and mature later that same summer, without vernalization.

For regions with poor summer rainfall, vernalization was used, which chilled seeds of winter varieties, then planting them in the spring.

Bolting is a robust predictor of flower formation, and hence a good indicator for vernalization research.

It can be grown as a cold hardy garden plant, needing vernalization (a period of cold weather) in order to flower.

Lysenko's 1928 paper on vernalization and plant physiology drew wide attention due to its practical consequences for Russian agriculture.

Day neutral plants do not initiate flowering based on photoperiodism, though some may use temperature sensitivity (vernalization) instead.

Winter varieties do not flower until springtime because they require vernalization: exposure to low temperature for a genetically determined length of time.

Lysenko's vernalization practices yielded marginally greater food production on the farms, and he was quickly accepted as the hero of Soviet agriculture.

Many plants grown in temperate climates require vernalization and must experience a period of low winter temperature to initiate or accelerate the flowering process.

Due to plant flowering requiring the successful co-operation of several metabolic pathways, computer models that incorporate vernalization have also been made.

Where winters are too warm for vernalization or exceed the hardiness of the crop (which varies by species and variety), farmers grow spring varieties.

Tulips are indigenous to mountainous areas with temperate climates and need a period of cool dormancy, known as vernalization.

Decrease in potential yields is likely to be caused by shortening of the growing period, decrease in water availability and poor vernalization.

After vernalization, plants have acquired the ability to flower, but they may require additional seasonal cues or weeks of growth before they will actually flower.

Some variants, called "winter annuals", require vernalization to flower; others ("summer annuals") do not.

Typical vernalization temperatures are between 5 and 10 degrees Celsius (40 and 50 degrees Fahrenheit).

Early research on vernalization focused on plant physiology; the increasing availability of molecular biology has made it possible to unravel its underlying mechanisms.
