Will a long-day plant (LDP) bear flowers after it was subjected to nights interrupted by flashing red light?
Step by step
Solved in 2 steps
- Phytochrome is a plant pigment protein that mediates plant infection promotes plant growth mediates morphological changes in response to red and far-red light inhibits plant growthWill a long-day plant (LDP) bear flowers after it was subjected to nights interrupted by flashing red light followed by far-red light? *Does red color generally attract birds and so facilitate pollination in a wide range of flowers?
- If a plant flowers in a controlled chamber with a daily cycle of 10 hours of light and 14 hours of darkness, is it a short-day plant? Explain.Owners and managers of plant nurseries have to plan lighting schedules for a long-day plant that will flower in February. What lighting periods will be most effective? What color of light should be chosen?We know that short-day plants do not really need short days, but actually long nights. Describe the type of treatment that proves this. Is some kind of light given during the night or some period of darkness given during the day?
- Light is often the most important environmental factor for inducing a plant to flower, but it is not the intensity of light. What it the important aspect?The signaling molecule for flowering might be released earlierthan usual in a long-day plant exposed to flashes of(A) far-red light during the night.(B) red light during the night.(C) red light followed by far-red light during the night.(D) far-red light during the dayWhy did plant physiologists propose the existence of a mobile molecule(florigen) that triggers flowering?
- A long day plant is given a long night, and is interrupted by a light pulse in the middle of the night. Which quality of the light pulse will most likely prevent flowering? Select one: a. UV light b. green light c. red light d. far-red lightCan you answer this question, all of the parts please. A. Please explain the phenomenon of apical dominance in plant growth. B. Which plant hormone(s) involved in apical dominance?Both a short day plant and a long day plant can produce can flowersimultaneously in a given place’. Explain.
