Vernalization if the process of artificial induction of plant's flowering process which is discovered by Gassner and flowering time also changed by external factors.

The acquisition or acceleration of the ability to flower by a chilling treatment is said to be vernalization. It is the method of inducing early flowering in plants by pretreatments of their seeds at a very low temperature. Low-temperature effects may be obtained at any stage of plant development. The most effective temperature for vernalization is between 0 to 5 degree C. The duration of cold treatment for effective vernalization varies from four days to eight weeks. Thus option C is the correct answer. 

Vernalization is the acquisition of a plant's ability to flower in the spring by exposure to the prolonged cold of winter, or by an artificial equivalent. It can also refer to herbal plants requiring a cold dormancy to produce new shoots and leaves. The stimulus of vernalization is known as vernalin. The stimulus of vernalization that induce flowering could be a particular gibberellin or a mixture of gibberellins.

In many plants, the temperature has a profound effect on flowering. Some plants do not flower under the inductive photoperiod conditions but flower when a cold temperature treatment is given to them. This acquisition or acceleration of the ability to flower by a chilling treatment is said to be vernalization. It is the method of inducing early flowering in plants by pretreatments of their seeds at a very low temperature. Thus option B is the correct answer. 

• Vernalization is a method in which the seeds or the plants are exposed to certain treatments in order to initiate the process of flowering. 
• Generally, the plants are exposed to cold treatment, which induces the plants to produce flowers. 
• This term was introduced by T. D. Lysenko in the year 1920.
• Thus, the correct answer is option B. 

Lodicules are two scale like structures that lie at the  base of the ovary of  a grass flower including jawar .

Vernalization is the process by which plant can be induced to flower by exposing it to the prolonged cold or winter. The term was coined by Lysenko in 1928. He stated that certain plants can be made to flower by providing cold treatment to young plants or moistened seeds.

Vernalization is the process by which plant can be induced to flower by exposing it to the prolonged cold of winter. The term was coined by Lysenko in 1928. He stated that certain plants can be made to flower by providing low temperature treatment to young plants or moistened seeds. Other terms like jarovization, springification were also coined for the same phenomenon. However, today the most accepted term is vernalization.

Vernalization is the process by which plant can be induced to flower by exposing it to the prolonged period of low temperature or cold. After this, plants show quicker flowering. The term was coined by Lysenko in 1928. He stated that certain plants can be made to flower by providing low temperature treatment to young plants or semigerminated seeds.
