Plant Physiology - Greenhouse MGMT Flashcards
the natural process of leaves falling from the plant
Abscission
The uptake of nutrients from the soil solution.
Absorption
The process by which plants adapt to another climate or environment
Acclimatization (or acclimation)
Advanced period of plant growth, leads to flowering and production of seed
Adult stage of growth
Roots that remain in the air and exchange oxygen and carbon dioxide; they do not absorb water unless they enter a medium or fasten themselves to a solid surface.
Aerial roots
Lives without oxygen
Anaerobic
Pollen-bearing structure that is found at the end of the filament.
Anther
A bud that develops in the angle(axil) the leaf makes with the main stem.
Axillary bud
A modified leaf that may be highly colored; poinsettias have very colorful red ____s
Bract
The death of the developing flower bud, usually because of water stress.
Bud blasting.
A small daughter bulb of a bulb producing crop.
Bulblet
Made up of the sepals.
Calyx
Small daughter structures produced by a corm; gladiolus produce these
Cormels
All of the petals together.
Corolla
The first seed leaves that develop
Cotyledon leaves
A group of closely grouped stems or plantlets; African violets form multiple of these.
Crown
The resting stage of seed or plant.
Dormancy
Stretched, leggy seedlings resulting from exposure to a very low light intensity.
Etiolated seedlings
Stalk-like unit holding the anthers.
Filament
The first true stem of the seed.
Hypocotyl
The flowering head of a plant.
Inflorescence
Early stage of plant growth.
Juvenile stage of growth
An enzyme that controls the response of plants to day length
Phytochrome
Female reproductive part of the plant consisting of the stigma, style, and ovary.
Pistil
The part of the pistil that receives the pollen grain
Stigma
The specialized tissues that make up the pipelines that conduct water and nutrients through the plant.
Vascular tissue
Nonflowering growing point of the plant
Vegetative meristem
