Color Break Comments
COLOR BREAK: Caused by Other Than Virus Some plants produce abnormal flowers with a white or light wedge in a petal and may do so every few years. A66-134; OD71-199 0
COLOR BREAK, MILD: Caused by Both Major Virus Infections Chlorotic streaking appears in new leads, disappears in mature leaf; an illusive disease; plants can act as carriers to other plants where symptoms become more readily noticeable. A73-818; N322 0
COLOR BREAK, SEVERE: In Cattleyas Another disastrous disease caused by "severe color break disease"; color is patchy with ugly areas of pigmentation; it sometimes deforms flowers; plant is also affected -- new leads appear with rosy mottling, or leaves show raised ridges and bumps, perhaps are twisted. A73-819; B46; BU57 0
COLOR BREAK, SYMMETRICAL: In Cattleyas Dark pigment outlines sepals and covers all but the median area of the petals; it is a virus. N322 0
COLOR BREAK: Virus Induced in Cattleyas Cymbidium mosaic virus does not cause color-breaking; tobacco mosaic virus orchid strain induces it; illus. of infected flowers; diagrammatic plant with locations of virus. A70-395; BU57; OD71-199; S208 0
