HORTICULTURE

Detailed explanation-1: -To induce flowering you simply expose the plants to more than 12 hours of light each day. A similar method can be applied to control when your plants drop their leaves and become dormant. To do this the plant must think that it is getting late in the season and thus close to winter.

Detailed explanation-2: -Vernalisation is defined as the qualitative or quantitative dependence of plants on exposure to a low temperature to flower.

Detailed explanation-3: -Plants have the tendency to grow towards light, this phenomenon is called phototropism. It occurs in plants due to the presence of plant hormone auxin which is highly light sensitive. Thus, it is also responsible for the movement of hormones. Thus, light directly influences the growth and development of plants.

Detailed explanation-4: -An increase in leaf area can be due to the production of an enlarged primordium during the initiation at the meristem and/or to a progressive increase in size resulting from a faster and/or a prolonged growth period.
