Which Of The Following Can Delay Or Prevent Senescence In Plants? The hormones that delay senescence must decrease while the ones that speed up the aging process must increase. Cytokinins are one group of senescence delayers. These hormones are involved in cell growth, and high levels can help prevent senescence. Which hormone delays senescence in
How Treatment With Gibberellic Acid Will Affect The Cabbage? THE EFFECT OF GIBBERELLIC ACID (GA3)ON PLANT GROWTH BEFORE AND AFTER TRANSPLANTING. GA3 applied as a foliar spray on the Chinese flowering cabbage at 20 ppm, 10 days after transplanting, significantly enhanced the growth of the crop; but the transplanting date of the Chinese flowering cabbage
Is The Only Plant Hormone In Gaseous Form? ABA. Hint: The only plant hormone that is found in gaseous form helps in ripening of fruit. Farmers control the synthesis of this hormone by several physiological means and prevent the ripening of fruits. This hormone can also communicate with other plants via air. Which of the
What Is The Effect Of Gibberellins On Plants? Gibberellins are a group of plant hormones responsible for growth and development. They are important for initiating seed germination . Low concentrations can be used to increase the speed of germination, and they stimulate cell elongation so plants grow taller. They are naturally produced by barley and
How Does Auxin Produce Phototropism? Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. What is abscission layer in plants?
Which Examples Are Plant Responses To Hormones Check All That Apply? The best-known effect of the hormone is the promotion of fruit ripening: ethylene stimulates the conversion of starch and acids into simple sugars. Ethylene also triggers leaf and fruit abscission, flower fading and dropping. Which examples are plant responses to hormones? The best-known effect
How Do Plants Respond To Stimuli Give Examples? Plants respond to various stimuli. … Phototropism: Movement or growth of plants towards light is called phototropism. For example, sunflower turning towards the sun. Hydrotropism: Plant roots grow deeper into the soil in response to higher water concentration. How do plants detect stimuli? A plant’s sensory response
What Are The 5 Major Plant Hormones? There are five groups of plant-growth-regulating compounds: auxin, gibberellin (GA), cytokinin, ethylene, and abscisic acid (ABA). For the most part, each group contains both naturally occurring hormones and synthetic substances. What are the five classical plant hormones? Since 1937, gibberellin (GA), ethylene, cytokinin, and ab- scisic acid (ABA)
What Is The Stimulus For Phototropism In Plants? Phototropism is a growth response where the stimulus is light, whereas gravitropism (also called geotropism) is a growth response where the stimulus is gravity. What is the stimulus in plants? Stimulus in plants The plant responds to many types of external stimuli such as light, gravity, weather,
Do Plant Hormones Travel In The Air? Ethylene can be produced in almost any part of a plant, and can diffuse through the plant’s tissue, outside the plant, and travel through the air to affect a totally different plant. How are growth regulators transported in plants? A plant growth regulator is a chemical that controls
