The various kinds of plants that may be attacked by a pathogen or insect.
Industry:Agriculture
The relative genetic ability of a cultivar to produce a larger or higher quality crop compared with other cultivars exposed to the same infestation level.
Industry:Agriculture
A plant that provides nourishment and protection to a parasitic organism, living plant, or animal.
Industry:Agriculture
A type of pseudoresistance where the plant evades insect injury by passing through the susceptible stage quickly or when insect numbers are low. An example is an early-maturing variety which is harvested before the insects reach damaging levels.
Industry:Agriculture
The organism on which a parasite lives or the plant on which a pest feeds.
Industry:Agriculture
Regulatory substance that controls metabolism and development, acts at low concentrations (e.g., less than one ppm, micromolar) and at a distance from its site of synthesis.
Industry:Agriculture
Resistance governed by many genes of minor effects which provide resistance (usually moderate) to any (or all) diseases or insect biotype of a given species, but can be easily affected by the environment (e.g., a variety may be susceptible in the greenhouse but may be resistant in the field or vice versa). A type of resistance expressed equally against all biotypes of a pest species. It does not involve a gene-for-gene relationship.
Industry:Agriculture
The complete drying up of rice plants caused by the extensive feeding by large number of planthoppers which suck plant sap (e.g., brown planthoppers Nilaparvata lugens).
Industry:Agriculture
A sugary liquid excretion of plant-sucking hoppers which consists of a mixture of undigested plant material and excretory products.
Industry:Agriculture
Having one type of allele in both chromosomes for a given gene or genes. Having the same members of the allelic gene pair, either dominant or recessive on both chromosomes, and producing only one kind of gamete.
