Mango Glossary

GRIN stands for Germplasm Resources Information Network, the USDA information system supporting documentation of genetic resources. Plant records can include accession identifiers, taxonomy, collection history, and evaluation information relevant to mango research. It is a reference and collection-management resource, not a guarantee that every cultivar claim found elsewhere is correct or that plant material is available to every requester. Distinguish a documented accession from a commercial nursery name when investigating the identity or history of a mango.

A grow light supplies artificial light for plant growth when daylight is inadequate. For container mangoes kept indoors during cold weather, useful performance depends on the light reaching the leaves, coverage, daily operating time, and distance from foliage, not just the lamp's advertised wattage. Increase exposure gradually and monitor heat and leaf response. Supplementary light can maintain a tree through winter, but it does not automatically provide the space, pollination, and environmental conditions needed for a dependable indoor crop.

Gummosis is the exudation of gum-like material from damaged or stressed plant tissue, often visible on mango trunks or branches. It is a symptom rather than a single disease: injury, insects, infection, and environmental stress can produce similar appearances. Examine the site for wounds, boring holes, discoloration, and spreading dieback before deciding on management. Repeatedly cutting or coating the area without identifying the cause can worsen damage. A diagnostic assessment is more useful than assuming every gum deposit has the same treatment.
