Application of Ethylene increases the number of female flowers in cucumber plants, thereby increasing the final yield.
What is the effect of ethylene on cucumber plant?
It is well established that ethylene promotes female flower development in cucumber. However, little is known about how the gaseous hormone selectively affects female flowers, and what mechanism it uses. Previously, we found organ-specific DNA damage in the primordial anther of female cucumber flowers.
Does ethylene promote male flowering in cucumbers?
Ethylene is a simple gaseous natural plant growth hormone. Cucumber has separate male and female flowers. Ethylene increases the number of female flowers in cucumber and thereby enhances the yield.
Which hormone induces femaleness in flowers of cucumber?
Hence, Auxins, Cytokinins and Ethylene are the hormones that increase the femaleness in plants. Was this answer helpful?
How does ethephon increase the yield of cucumber?
By increasing the number of female flowers. By increasing the number of both male and female flowers.
How do cucumbers induce female flowers?
The soil that is rich in organic matter, such as composted animal manure, will encourage more female cucumber flowers. Adding organic liquid fertilizer high in Nitrogen and Potassium will improve soil quality and promote more female flowers.
Is ethylene a chemical?
Ethylene is an important industrial organic chemical. It is produced by heating either natural gas, especially its ethane and propane components, or petroleum to 800–900 °C (1,470–1,650 °F), giving a mixture of gases from which the ethylene is separated.
How does ethylene promote female flowers in cucumbers?
(2010), together with previous studies published in the last decade, have provided evidence suggesting a link between ethylene signaling and primordial anther specific DNA damage in female cucumber flowers. These findings explained ethylene promotion of female flower by ethylene inhibition of stamen development.
Which hormone promotes the production of male flowers in cucurbits?
Gibberellins
Solution : Gibberellins promotes the production of male flowers in Cucurbits.
Which PGR is used to increase the yield of pumpkin?
Spraying with GA 3 25 ppm in four leaf stage at trellis method could be a suitable treatment for enhancing growth and yield of medicinal pumpkin.
Which hormone is used for killing weeds Dicots?
Synthetic auxin (2-4 d)kills broad leaved dicot weeds hence used as weedicides
E.
What is the function of cytokinin?
Cytokinins are a group of plant growth regulators which are primarily involved in performing cell division in plant roots, shoot system. This hormone helps in promoting the cell’s growth, development, differentiation, affecting apical dominance and delay in leaf senescence.
How do cucumber plants encourage male flowers?
Cucumbers will fail to bloom when they lack energy. The leaves need to be green for photosynthesis, and the soil must be rich in nutrients. Adding blood meal to the soil boosts nitrogen and phosphorous. It needs high temperatures for male flowers and cooler temperatures for female flowers.
Why are plant hormones called growth regulators?
As the plants require oxygen, water, sunlight, and nutrition to develop and grow, they do require certain chemical substances to manage their growth and development. These chemical substances are known as Plant Growth Regulators and are naturally produced by the plants itself.
Which of the following hormone has triple response?
ethylene
Triple response is the peculiar characteristic of ethylene. Germinating seedlings synthesize ethylene when their growth is impeded by the soil.
Which of the following is a gaseous plant growth regulator?
Ethylene is a gaseous plant hormone (phytohormone) produced by almost all parts of plant but meristematic tissues are considered as active sites for its production. Being a gaseous hormone it diffuses to other parts of the plant from its site of synthesis. Ethylene has the simplest structure (C2H4).
How do you increase the yield of a cucumber?

How do you make cucumbers grow faster?
Cucumbers will grow quickly with little care. Be sure they receive an inch of water every week. Make the most of your food growing efforts by regularly feeding plants with a water-soluble plant food. When soil is warm, add a layer of straw mulch to keep fruit clean and help keep slugs and beetles away.
Is ethylene harmful to humans?
HAZARD SUMMARY
* Ethylene gas can affect you when breathed in. * Skin contact with liquid Ethylene can cause frostbite. * Exposure to Ethylene can cause headache, dizziness, fatigue, lightheadedness, confusion and unconsciousness.
Why do we need ethylene?
Ethylene is the essential building block to make resins and plastics. Approximately 200 million tons are produced annually, and its worldwide production exceeds any other organic compound.
