What is the factors that initiates flowering in a long day plants?
Nights shorter than a critical length. Long day plants can also be thought of as short night plants.
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.

Flowering tundra plants must bloom and set seed quickly because?
The summers are very short
When flowering tundra plants they must bloom and set seed quickly because?
The summers are very short
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 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.
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.

What plants are on mount McKinley?
Over 650 species of flowering plants, mosses, lichens, fungi, and algae grow on Mt. McKinley. Only plants that have adapted to the harsh winters and short growing season can survive on Mt. McKinley.
Are daisies short-day plants?
No, they grow the most in the spring and summer!
Can you freeze tulip bulbs for a short time and replant to bloom again?
Not freeze, but they are often chilled in a cold store to enable control of flowering times.
