Control of Flowering by Floral Bud Removal in ×Aranda Christine under Tropical Field Conditions

Abstract

The growth and flower production of×Aranda Christine cv. “130” grown under tropical field conditions were studied. On the average, an Aranda orchid produced 2-5 leaves and an increase of 7cm in height per month for the first 18 months after transplanting. Cut flower production was evident only 5 months later. Aranda has 3 major flower peaks-April, June and December. Cut flower production of×Aranda Christine could be successfully staggered by floral bud removal. Through bud removal, it is possible to shift the flower production peak for 2 weeks. No apparent effect of bud removal on flowering and flower quality was observed as the subsequent flowering behaviour was normal.
