What factor primarily determines the time of year that a plant flowers?
Photoperiod determines the time of flowering in many plants. Accordingly the plants have been classified as short day plants, long day plants and day neutral plants. A short day plant can be brought into flowering by putting in the dark for a specific period of time for the required days. Similarly, long day plants can be subjected to artificial light of desired intensity to initiate flowering.Photoperiod determines the time of flowering in many plants.

What is the difference between florigen and phytochrome?
florigen )its a hormone responsible for inducing flowering in plants directly )moves from leaves to the apex inducing flowering by phloem mechanism )no inter conversion from one phase to other phytochrome )it is a light absorbing pigment which induces flowering in long day plants )pigments p660 and p730 absorb red and far red light respectively )p660absorbs red light and immediately converts into p730 and as p730 absorbs far red light which induces flowering thus flowering is induced in long day plants because p730 is present in day
What did early experiments on photoperiodism demonstrate?
Early experiments on photoperiodism dealt with the flowering period of plants. They defined short-day ( late summer and fall, less than about 16 hours ), long-day ( summer, longer than 9 to 16 hours ), day-neutral ( any length ), and intermediate-day ( not classifiable as either long-day or short-day) plants in relation to their photoperiod.

Do garlic plants bear flowers?
yes, garlic is a member of the onion family (Alium) and produce flowering umbles
What is photoperiod?
Photoperiodism is a response that certain plants have to decreases or increases in the amount they receive in a day (which is normally produced by seasonal movement of the sun - longer and shorter days). Some plants require short days to initiate flower formation, while others long day length initiates flowering. This process can be artificially created in greenhouses using curtains and artificial light to "trick" certain plants like chrysanthemums and poinsettia to flower outside of their natural flowering period. Photoperiodism is controlled at a cellular level by photoreceptor proteins in the cells of the plants. Phototropism is a the mechanism whereby plants grow towards the light (like a houseplant growing towards the window), or in the case of certain flowers like sunflower the way in which the "flower" tracks the path of the sun
Are ferns a flowering plant?

What should you know about day-neutral plants?
Daily periodicity of light (photoperiod) plays very important role in initiating flowering in a variety of plants. On this basis plants are classified as 1. long day plants, 2. short day plants and 3. day -neutral plants. Day neutral plants are not affected by daily photoperiod for their flowering whereas 1 & 2 category require long duration & short duration of light for flower initiation respectively.
What is Chailakhyans hyphothesis of vernalization?
according to this hypothesis,the application of gibberellins on long day plants in non-inductive cyles will induce flowering,while in short day plants if non inductive cycle is provided then application of gibberellin has no effect on floweringi.e. flowering will not be induced.
What is the difference between a hartstongue and a dafodil?
A hartstongue is a type of fern that has long, strap-like fronds, while a daffodil is a type of flowering plant from the Narcissus genus that produces yellow or white trumpet-shaped flowers. Hartstongues are non-flowering plants, while daffodils are flowering plants.
What is the action of phytochrom pigment in plant flowering?
Phytochrom-FarRed increases during the day to inhibit flowering. At night it degrades slowly to Phytochrom-Red which does not inhibit flowering. "Short-Day" plants need long nights to complete this process in order to flower in the late summer.
