Terms Relative to the Postharvest Biology of Living Plants and Plant Parts
[ Return to Postharvest Biology ]
| Chemicalxcompositionx(plant)x- |
The main chemical components of a plant or plant part. |
| Chemical composition (plant) - |
The main chemical components of a plant or plant part. |
| Cooling - |
The removal of heat from a harvested product. |
| Energy balance - |
Balance between energy taken in and energy released from a plant or
plant part. |
| Ethylene synthesis rate - |
A measure of the rate of synthesis of the phytohormone ethylene,
often expressed as _L of ethylene*kg-1 of product*hr-1. |
| Flower sensitivity to ethylene - |
The susceptibility of flowers to the deleterious effect of
the phytohormone ethylene. |
| Gene expression - |
Process by which a gene's coded information is translated into proteins
or RNAs. |
| Heat transfer - |
The movement of heat from one location or substance to another by one of
more of the following means: radiation, convection and conduction. |
| Maturation - |
The process of becoming fully developed. |
| Maturity - |
A point in the overall development of a plant or plant part, the timing of which depends upon whether it represents biological maturity (i.e., capable of shifting from the vegetative to reproductive phase) or harvestable maturity (i.e., meets our requirements for harvest). |
| Metabolic pathway - |
A series of chemical reactions within a cell that are catalyzed by enzymes and result in either the formation of a metabolic product or the initiation of another metabolic pathway. Pathways generally involve a step by step modification of an initial substrate to form a product with an exact chemical structure. |
| Metabolism (plant) - |
The chemical processes occurring within a living plants or plant cells that are necessary for the maintenance of life. |
Movement and exchange of
gases, solvents and solutes - |
The transfer of molecules within a harvested product and/or between the product and its surrounding environment. |
| Perishable plant products - |
Living plant parts/products that will eventually spoil and decay. |
| Phytohormones - |
Hormones synthesized in plants that regulate growth and development. |
| Phytohormones - |
Hormones synthesized in plants that regulate growth and development. They are produced in low concentrations at specific locations within the plant and function as signaling molecules modulating processes in target cells at other locations. |
| Postharvest biology - |
A division of plant biology that deals with the study of plant material after it has been harvested. |
| Quality - |
The composite of those characteristics that differentiate individual units of a
product and have significance in determining the unit's degree of acceptability to
the user. |
| Recombinant DNA - |
DNA that has been altered by transplanting or splicing genes from
one species into the cells of a host organism of a different species. Such DNA
becomes part of the host's genetic makeup and is replicated. |
| Recommend storage conditions - |
The temperature, relative humidity and gas atmosphere
composition that gives superior storage longevity of a harvested plant product. |
| Respiration (plant) - |
Oxidative metabolic processes whereby plants obtain energy from
organic molecules; a process that takes place in living cells during which oxygen
from the surrounding environment is utilized, energy released, and carbon dioxide
produced. |
| Respiratory rate - |
A measure of the rate of respiration by a plant or plant part, often
expressed as mg of CO2*kg-1 of product*hr-1. |
| Storage - |
The act of storing plants or plant parts for future use. |
| Stress - |
An external factor (or succession of factors) of such magnitude that it tends to
interrupt, restrict or accelerate normal metabolic processes and does so in an
adverse or negative manner. |
| Transgenic plant - |
A plant in which a foreign DNA gene has been incorporated into its
genome. |
| Postharvest losses - |
Losses in product quantity and quality between harvest and utilization,
deterioration or death. |
| Postharvest pathogens - |
Microorganism that result in losses during the postharvest period. |
| Postharvest herbivores - |
A wide range of invertebrates and vertebrates that feed on
harvested plant products causing qualitative and quantitative losses. |
| Mechanical damage - |
The physical alterations to harvested plant products mediated by a
diverse range of mechanical stresses. |
| Gravitational stress - |
The stress imposed by altering a plant or plant part's orientation to
the earth's gravitational field which can result in undesirable changes in product
quality. |
