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
- Will a long-day plant (LDP) bear flowers after it was subjected to nights interrupted by flashing red light followed by far-red light? *A short-day plant flowers only when exposed to light for less than 12 hours long. Which of the following would cause the plant to flower? * O a 13-hour night and 11-hour day with 1 minute of darkness after 6 hours a 12-hour day and 12-hour night with a flash of red light an 8-hour day and 16-hour night with a flash of white light after 8 hours O a 9-hour night and 15-hour day with 1 minute of darkness after 7 hours 24 hours of continuous lightDescribe how photoperiod affects the flowering of the following group of plants : i) day-neutral
- Predict whether flowering in a short day plant with a minimum critical length of 14 hours would be expected to occur in the following situations. The plant is exposed to 15 hours of daylight and 9 hours of darkness uninterrupted. The plant is exposed to 9 hours of daylight and 15 hours of darkness. The plant is exposed to 9 hours of daylight and 15 hours of darkness, with 10 minutes exposure to red light in the middle of the night.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.Which phytochrome is sensing the shading and what are the TWO (2) rapid shade avoiding responses? *
- 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?What is photoperiod (photoperiodism) ? Explain the affects of photoperiod (photoperiodism) ?Discuss other morphological differences between sunny and shady set-ups of mung bean in relation to phototropic response of plants. Characteristics sunny shaded Leaf color Lime Green Pale Green Direction of Growth Grows upward towards the direction of sunlight Oriented in the direction of the light but growth is bent downward
