Application Of Plant Hormones Flashcards
Agriculture
The art and science of farming involving cultivation soil and growing crops
Horticulture
The art or practice of garden cultivation and management
Uses of auxins
Herbicides, rooting powders, promoting growth in tissue culture
Auxins in rooting powder
Auxins in specific concentrations can promote the growth of the roots of plant cuttings
Auxins in weed killer
Auxins in high concentrations can cause plants to grow too facts and use up energy stores and die
Selective weed killer
Auxins can target specific plants by causing them to grow quicker and absorb substances such as weed killer at a faster rate
Negative impact of weed killer
Can significantly reduce biodiversity and impact food chains
Tissue culture
A plant divided into small cultures of cells that is incubated with plant hormones for the mass production of identical plant clones
Plant cuttings
A piece of a plant that is removed and dipped in rooting powder to produce a genetically identical plant clone
Plant clones
Genetically identical plants that can be quickly produces and have identical characteristics
Applications of plant clones
Can be used for plant species conservation, scientific research or for horticultural purposed
Apical meristem
The growth region in plant shoots and roots containing undifferentiated cells and is also the site of auxin production
Gibberellins
Plant hormones that are important in the intimidation of seed germination
Uses of gibberellins
End seed dormancy by encouraging early germination, promote flowering, increase fruit size and produce seedless fruit
Ethene
Plant hormone that controls cell division and promotes ripening of fruits
